  • http://www.jsonline.mobi/news/wisconsin/125448073.html?ua=android&dc=smart&c=y A former maintenance worker at Appleton Medical Center who was seriously injured when a manhole cover blew off a boiler and struck him in the head in 2009 has reached a $1.6 million settlement with the company that was servicing the boiler and its insurance companies, according to the worker's attorneys. Daniel J. Quaintance, 56, of Appleton was following directions from a technician employed by the service company, BurCon Services, Inc. of Green Bay, when the boiler exploded, a news release from attorneys at Habush Habush and Rottier says. Quaintance suffered a traumatic brain injury as well as extreme blood loss, numerous broken bones in his face, respiratory failure, eye damage, hearing loss and some facial nerve damage, according to his lawyers. After the explosion, he was airlifted to Theda Clark Medical Center in Neenah, where he was hospitalized for more than a month, his lawyers said. Quaintance contended the explosion was a result of the BurCon worker's negligence, according to the complaint. Although Quaintance suffered some permanent residual effects from the explosion, he recovered enough to return to work within about six months, according to his attorney, Craig Christensen. About $90,000 of the settlement money has been set aside for future medical expenses, according to the agreement. "I think most people would be shocked that he wasn't killed," Christensen said Tuesday. "I think he's very thankful that he's been able to make the recovery to the extent he has and get on with his life as best he can." The BurCon worker who was in the boiler room with Quaintance at the time of the explosion was treated for minor injuries and released from Appleton Medical Center, Christensen said. The hospital was not evacuated, he said. The main impact on patients was that surgical instruments were not able to be sterilized for a period of time, he said. Daniel Hurst, a lawyer who represents BurCon and Cincinnati Insurance Co., was out of the country and could not be reached Tuesday. They continue to allege that Hurst Boiler, which manufactured the unit, bears some of the responsibility for the explosion because of negligent design, Christensen said.
  • On February 1, 1999 a natural gas explosion at the power plant for the Ford River Rouge facility near Dearborn, Michigan, triggered subsequent secondary explosions of coal dust that had accumulated on surfaces in the plant. Six people died and another 30 were injured. The power plant had to be completely rebuilt. Six employees were taking a boiler off-line for maintenance. A natural gas valve was inadvertently left open. When a secondary butterfly valve was opened for purging, gas entered the unfired boiler which was still hot. This resulted in an explosion in the boiler and that explosion caused secondary explosions from coal dust that had accumulated on building and equipment surfaces. All six employees were killed in the explosion. Cause and contributing factors The explosion occurred as maintenance workers and welders shut the boiler down so that it could be serviced. The boiler operators had turned the burners off from the control room so that a blank could be installed in the west gas line to start a nitrogen purge flow between the second-floor manual valve and the boiler. In the process, the main valves on the natural gas lines are normally turned off. The operator then opens the burner valves to allow the purged gas to pass through the boiler. Employees in the final stages of inserting the blank opened the gas valves to the west burners and to the east natural gas burners. However, the manual natural gas valve on one of the main gas lines on the second and third floors had not been closed, and gas flowed into the boiler through the three east natural gas burners mixing with air from an operating forced-draft fan for 90 to 120 seconds before the flammable mixture was ignited, probably by hot fly ash residue or the discharge of the electrostatic precipitator. Moments before the explosion, an employee in the control room noticed the mistake and tried to alert the crew, but it was too late. The resulting explosion vented flames and hot gases that raised dense coal dust clouds from the accumulated layers in the building. These dust clouds ignited, causing secondary explosions to propagate through the boiler house to remote areas such as the pulverizer building. The MIOSHA report concluded that several factors contributed to the incident. Among these were the lack of operating igniter and flame-sensing interlocks that would have prevented natural gas flow into the furnace without any flame or igniter and the lack of specific written procedures for shutting down and blanking the natural gas lines. Communication among the boiler operators and the crew performing the gas line blanking procedure was also inadequate.
  • Companies such as Trainco offer Boiler Maintenance Classes Do all boiler operators know how to operate the boiler within the permit limits? At the beginning of each shift, how do the boiler operators make sure the equipment is operating properly? Where the boiler’s operating and maintenance manual? What training have the Boiler Operators received?
  • 8- A boiler room log is used to record information regarding operation of the boiler during a given period of time. The number and frequency of the checks to be performed depend on the plant. Some plants maintain a log for every 8-hour period. Other plants maintain a log for a 24-hour period. Maintaining a boiler room log allows the operator to evaluate the past performance of the boiler. In addition, boiler room log information can be useful in determining the cause of a malfunction and/or predicting a possible problem.

  • Environmental Inspection Post a copy of the air operating permit near the boiler Ensure all boiler operators know how to operate the boiler within the permit limits At the beginning of each shift, make sure the equipment is operating properly Boiler operators should be familiar with the boiler’s operating and maintenance manual Regular service should be performed on schedule and recorded Operating records and inspection records should be reviewed regularly to ensure compliance
  • 8- There is no routine maintenance on a safety valve. However, safety valves are routinely tested to ensure proper operation. Safety valves are commonly tested by lifting the safety valve try lever. . With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible. Replacement safety valves must comply with the ASME Boiler and Pressure Vessel Code and all design specifications of the boiler. Any adjustments or repairs to a safety valve must be performed by the manufacturer or an authorized manufacturer representative. An evaporation test can also be used it is more accurate because it replicates a more realistic situation The feedwater is secured and water is allowed to evaporate. This is not necessary if a proper type cutoff is used. PPE used for this testing would general require insulation gloves. Refer to your company safety plan for instructions.

  • Image from http://www.tpub.com/content/construction/14279/css/14279_56.htm During 1996, a total of 1,211 incidents were reported in North America with respect to heating boilers (both steam and water) and 602 of them (fully 49.7%) were caused by a low water condition. Of the remaining 609 incidents, 346 were reportedly caused by operator error or poor maintenance. This shows that over 78% of all incidents involving heating boilers occur as a result of low water condition and/or operator error or poor maintenance. LOW WATER FUEL CUT OFF shuts off fuel to the burner in the event of a low water condition in the boiler. The low water fuel cut off is located 2" to 6" below the boiler water level. Low water fuel cut offs operate using an electric probe or a float sensor, if the sensor indicates a low water condition a contact to the main burner control circuit opens and shuts down the main gas.   Low water fuel cut offs should be tested monthly or more often depending on usage or requirements. If a low water condition is not properly sensed and the gas train does not shut down, the boiler can overheat . Overheated boilers will be permanently damaged. If the safety valve has not been serviced properly and does not relieve the pressure adequately, the boiler may explode and result in injury  or worse.  
  • 8- Ensuring proper water level may be the most important duty of an operator. The gauge glass is the primary devise used in determining water level and must be maintained in proper condition. It is connected to the water column which levels out the turbulent water in the boiler so it can be accurately read.

  • 8- When blowing down the water column and gauge glass, the operator should carefully monitor the action of the water in the gauge glass. Water should enter the gauge glass quickly when the gauge glass blowdown valve is closed, indicating that the lines are free of sludge, sediment, or scale buildup. If the water returns sluggishly to its normal level, there may be an obstruction partially blocking the flow of water. If the apparent obstruction cannot be removed by blowing down, then the boiler should be shut down and allowed to cool. If the gauge glass is integrated with the low water fuel cutoff, the float (or probe) chamber should be opened and inspected. Mud, scale, or sediment deposits should be removed completely. Linkage should also be examined to ensure proper working order. All connecting piping should be inspected for any obstructions.

  • Employees #1, #2, #3, #4, and #5 were restarting the recovery boiler under a partial-natural-draft. The power boiler was not online at the time. The boiler exploded. Employee #1 turned on the ignition switch to relight the heater, however, the pilot did not come on, and he heard some rattling noise from the valve. So employee #1 turned off the switch. Employee #1 again turned on the ignition switch and asked the Employee #2 to bend down and see if the heater had ignited. As Employee #2 bent to see the pilot, a flare up occurred which burned Employee #1 and employee #2's face. Employee #1, a systems operator, and Employee #2, were present at the job site while Employee #3, was performing inspections on a boiler. The boiler installation was performed by a third party. During the final installation check up, the third party reported that the boiler would not light off. Employee #3 was sent to perform start-up checks on the boiler. During this process, the boiler exploded. Employee #1 was instantly killed, Employee #2 was seriously injured and Employee #3 was critically injured. Employee #1, #2, and other coworkers were restarting the boiler in the Steam Unit, when the boiler catastrophically failed. The boiler explosion threw Employee #1 under the structure of the B27 boiler, causing him to sustain fatal blunt force trauma. A coworker and Employee #2 suffered unspecified injuries. Employee #2 was transported to a medical center, where he received treatment and was hospitalized The employee went through relighting procedures and then placed a burning wick into the locomotive boiler fire box and opened the fuel line. Due to the position of the wick, more fuel vapor than normal entered the box before the fire lit. This caused a flash fire that came out of the firebox door and struck the employee. -------------------------------------------------------------------------------- Accident 201363249 - One Employee Is Killed, Four Others Are Injured in Explosion Accident 201363249 -- Report ID: 0419400 -- Event Date: 05/03/2008 Inspection: 311414544 Open: 05/05/2008 SIC: 1541 M-Co, Inc.

After performing the maintenance, employee #1 turned on the ignition switch to relight the heater, however, the pilot did not come on, and he heard some rattling noise from the valve. So employee #1 turned off the switch and called his supervisor over the phone for further technical assistance. Employee #1 again turned on the ignition switch and asked the Employee #2 to bend down and see if the heater had ignited. As Employee #2 bent to see the pilot, a flare up occurred which burned Employee #1 and employee #2's face. This explosion disappeared after 1-2 seconds. Nothing else was burned or blackened in the boiler room where other 3 boilers were present. Both employees were taken to the Stanford Hospital where they were observed and released. It was determined that both employees suffered minor first-degree burns.

Employee #1 was in the facility where waste heat from boilers is harnessed to generate electrical power. Employee #1 was restarting a stand-by/waste heat boiler; the boiler did not fire the first time it was started, so Employee #1 made a second attempt to fire the boiler, which triggered an explosion in the forced draft fan area (which feeds fresh air and by-pass flue gas.) Employee #1 sustained cuts and a first degree burn on his face. It is suspected that the purging of unused gasses may not have been complete and unused gasses may have been by-passed back to the system causing the explosion at the fan.

  • Accident 202490157 - Fall From Scaffold Accident 202490157 -- Report ID: 0950621 -- Event Date: 05/26/2010 Inspection: 313233991 Open: 06/30/2010 SIC: 1799 Safeway Services Lp Worker 1 was a member of a work team that was dismantling a scaffold that had been erected inside a large boiler, which was part of a power generation plant. An unrelated company had used the scaffold to gain access to all areas of the inside walls of the boiler to clean them. The cleaning process produced a large amount of fine, dark-colored dust on scaffold parts and working platforms. As the planks and frames of each level of the scaffold had been removed, more of the dark-colored dust began to fill the air and settle on the scaffold planks below. By the time all but a couple of planks remained on the second to lowest tier, Worker 1 repositioned himself on the lowest tier in order to reach up and remove the two planks remaining above him. Since the lowest tier was protected by rails on the outside and the wall of the boiler on the inside, Worker 1 believed it was no longer necessary to tie off. At this point in the operation, there was a lot of activity on the lowest tier with workers moving toward the area where scaffold parts were being handed down.

Employee #1 ensured that the boiler was in a safe condition to restart and that all the valves and controls were in the proper position. Then she began to open the main feed water valve to the boiler that is located over-head and can be opened through a chain drop between boilers three and four. While Employee #1 was opening the valve, she stepped backwards to better view the valve, when she tripped over a permanently installed pipe. The pipe was located 11 inches above the floor and took up about 12 inches in width of the walkway. Employee #1 was taken to the employer's on-site infirmary, where she was treated for a fractured left wrist. The incident investigation concluded that the walkway between the boilers did not lead directly to an exit, but did have impaired clearances that were not posted, guarded, or barricaded, and that presented a tripping hazard.

The employee used a 10-inch crescent wrench in an attempt to remove the nut below the broke pressure gage face. The 10-inch crescent wrench failed to move the nut. The employer was handed a hollow metal pipe by the coworker to be used as a cheater bar. A cheater bar was a pipe placed over the stem side of a wrench to create a greater length and created additional leverage to move a nut by the wrench. The additional leverage afforded with the cheater bar removed the nut. The broken pressure gage was removed. The employee replaced the pressure gage and attempted to tighten the nut associated with the pressure gage with the cheater bar. However, the hollow metal pipe making up the cheater bar slipped off the wrench, and the employee crashed backwards into nearby pump foundation. The employee suffered eight fractured bones in his right wrist. The employee was sent to Mt. Diablo Hospital for surgery.

At approximately 2:00 p.m. on June 14, 2006, Employee #1, working for Hazcorp Environmental Services, Inc., and two coworkers were performing an asbestos survey throughout a United States Gypsum (USG) paper mill for wallboard. This facility has multiple buildings, operations and floors. The three Hazcorp employees went through a half-hour contractor safety program with an USG engineering manager and were allowed to conduct their survey throughout the facility unescorted. Around 2:00 p.m. the three employees were taking asbestos suspect samples at the fourth floor level of the boiler house. They entered a small room (approximately 8-ft by 16-ft) in the northwest corner of the boiler house. The west side of the room was barricaded by a 3-ft, 6-inch yellow railing which had been installed by USG in January 2006. The railing had no gate and was clearly meant to block passage into that side of the room. The roof over that portion of the room was deteriorated and partially collapsed, leaving a lot of roof debris on the floor area of the barricaded side of the room. The area also contained a 3-ft, 5-inch by 6-ft hole, which at one time was for equipment or a chute (per USG management). USG had placed a piece of styrofoam board over the hole to keep the rain from entering the boiler house and barricaded the area to keep employees from entering that side of the room. Per USG, that area was unoccupied space for their employees the majority of the time. Over time, the roof debris covered the styrofoam board. Thus, the floor area behind the barricade looked like a complete solid surface. The other two HazCorp employees were discussing the need for a sample of the roofing material, which was lying on the floor on the barricaded side when Employee #1 went over the barricade and said he would get the sample. The other two employees did not stop Employee #1 from crossing the barricade or tell him to immediately return from the barricaded area. Employee #1 picked up the roof debris, stepped towards the wall, and fell through the floor hole. He fell 32 feet to the first floor of the boiler house. He most likely struck piping on the way down and landed between the wall and a dumpster. His two coworkers ran down to the first floor. One obtained help from USG and the other contacted 911. Employee #1 was flown by helicopter to Medical University of Ohio, where he was hospitalized in critical condition. He sustained a broken right clavicle, multiple subarachnoid hemorrhages, a left frontal subdural hematoma, right temporal subdural hematoma, pulmonary contusion, basilus skull fracture, and pneumocephalus (presence of air in the intracranial cavity).

On January 28, 2005, Employee #1 and a coworker, both employees of APCom Power Inc., were repairing a leaking tube in a boiler at the Independence Power and Light Blue Valley Power Plant. Independence Power and Light (IPL) had a service agreement with APCom Power Inc. to service boilers and repair leaks. The contract employees were working as a two-man crew with no direct supervision by IPL. Employee #1 was the foreman and both employees were boilermakers by trade. The coworker was working at the third floor level of the boiler performing welding on casings on the outside of the boiler. Employee #1 had finished all work inside the boiler and was scheduled to break down the basket of the single-point adjustable suspension scaffold and remove it from the boiler. The employees ate lunch together at 4:30 a.m. and the coworker went back to the third floor at 5:00 a.m. to resume his work duties. The next break time occurred at 6:15 a.m. and the coworker returned to the bottom floor of the boiler to check in with Employee #1 when he found him laying unconscious with his head against the boiler door, his feet straddling the scaffold basket, and the scaffold partially collapsed on top of him. The rollers of the scaffold mast were lying just below his navel, his thighs were between the top rail and mid rail of the work cage, and the hoist motor and motor mount were positioned at his knees. The coworker found an IPL employee and emergency services were called. The employees returned to the boiler and attempted to free Employee #1 from the scaffold. The coworker operated the scaffold hoist to take the slack out of the wire rope and lift the scaffold mast, motor, and motor mount from Employee #1's body. Another employee, an IPL shift supervisor, administered CPR to Employee #1 but never got a response. The Fire Department arrived at the scene at 6:24 a.m. followed by the American Medical Response ambulance service at 6:29 a.m. Employee #1 was transported to MCI hospital by ambulance where he was pronounced dead. An autopsy was conducted. The coroner's report indicated that the victim died of mechanical asphyxia from being trapped by the partially collapsed scaffold.

They were working in between two columns on the exterior side of a boiler wall. One employee was working from an aerial lift holding the sheets in place for the welder, who was working from a spider lift (suspended platform), located directly below. The two other coworkers were working from ground level hoisting the sheets into position for installation, while the supervisor was standing at ground level observing the operation. In order for the employee to access the location where the sheeting was to be installed, he turned the aerial lift basket sideways and extended the basket between the columns, through a gap of approximately 3 feet. The dimension of the basket was approximately 3 feet wide by 6 feet long. The steel sheeting was located approximately 4 feet horizontally from the exterior side of the wall. After the installation of the fifth sheet, the employee attempted to reposition the basket when it became lodged between the columns. He attempted to clear the lift and in doing so, hydraulic pressure had increased to the extent that when the basket became unlodged, it caused the lift to catapult and turnover. The basket was extended to reach a height of approximately 55 feet. The victim was tied off in the basket, but died as a result of the injuries he sustained from the fall.

Employee #1 and a coworker were installing an air line for an acoustic air horn system for the boiler on the fifth-floor boiler level of a fossil fuel electricity generating plant. They were installing piping for the air line near the east side doors to Boiler #1, which were located just below the fifth floor. They reached the doors by lifting a section of the floor grating and descending to the top of the boiler ventilation duct 58 inches below. Employee #1 and his coworker lifted a 22-inch by 35-inch section of the floor grating in order for Employee #1 to lower himself through the floor opening onto the top of the ventilation duct to take measurements. When Employee #1 returned to the fifth-floor level, he assisted his coworker in tightening the overhead portion of a pipe. The coworker was standing on a platform ladder at the south end of the boiler, approximately 5 to 6 feet away from the floor opening and was looking upward while tightening the south end of the pipe. Employee #1 was on a separate ladder and was tightening the north end of the same piece of pipe. Employee #1's ladder was positioned less than 12 inches from the floor opening. After both workers tightened and leveled the pipe, the coworker looked down to get his wrenches. Hearing a noise, he saw Employee #1 falling through the opening in the floor grating. Employee #1 hit the ventilation ductwork below, bounced off it, and fell approximately 15 feet further to the fourth floor grating. Employee #1 lost consciousness and sustained two lacerations to the back of his head, a concussion, and a broken scapula. He was hospitalized. Neither worker could recall what work surface Employee #1 was standing on immediately prior to falling (i.e., both feet on ladder, both feet on floor grating, one foot on ladder, one foot on grating, one foot on a pipe near the floor level, etc.).

On March 27, 2001 at 6:00 a.m. at work crew of seven to twelve employees reported to their work site. They were working twelve hours shifts. This work site for the first and second shifts was at a crane power plant. The assignment was to continue the removing of the secondary super heater tubes from a boiler type area. Employee #1, a modification mechanic, was working from the upper platform while a welder was working down on the main header pipe. Employee #1 walked out to the end of the upper platform and then stepped from the platform out and down on top of the section of heater tubes. He was a full body harness. Employee #1 chose not to tie off to the retractable safety device because he felt if he just used the lanyard and he fell it could swing him into the previous cut pieces of sharp jagged steel. If he used the lanyard would catch on the jagged pieces he thought a fall would let him hit the head pipe. He also thought that lanyard would catch on the jagged pieces of previously cut steel and possibly cause him to lose his balance and cause him to fall. He also was concerned that the sharp pieces of steel could damage the lanyard. Employee #1 stood up on the tube section and placed his left hand on a protruding I-Beam coming out of the wall. As he placed his left hand and weight on the I-beam and began to step up to the upper platform the I-beam broke away from the wall. Employee #1's glove caught on the metal of the beam and it pulled him down. It was estimated that the I-beam section weighed approximately 80 to 100 pounds. Mr. Cuba's hand came free of the I-beam and he continued to fall and he landed on the header pipe and then rolled off of the header pipe and fell to the floor below. When he hit the header pipe he landed on his left arm and his face hit the pipe. He was hospitalized. He suffered a broken left wrist, a broken left ankle, and numerous bruises. After the incident it was determined that another welder had cut partially through the I-beam because it was scheduled to be removed. Apparently he cut farther through than he realized. The retractable safety system was not erected in the proper location.

On February 2, 2000, Employees #1 and #2 were boiler workers employed by Black and Veatch. Employees #1 and #2 were removing the temporary bracing from the west side of the low pressure side of the Heat Recovery Steam Generator (HRSG), Unit 1. The temporary bracing consisted of three steel I beams that had been welded into position on the vertical columns. The three temporary beams on the east side had been removed on January 31, 2000. Employees #1 and #2 were using an Arc Gouger to cut the welds. Once the welds were cut, a sling was attached to the beam and to the hook of a crane. The beams were freed from the structure by breaking the slag with a hammer. Once freed, the beam was lowered to the ground. The top beam had been removed between 9:00 a.m. and 0930 a.m. Employees #1 and #2 took a coffee break sometime between 9:30 a.m. and 9:45 a.m. Upon returning from the break, Employees #1 and #2.proceeded to cut the top weld of the second temporary diagonal bracing.. Examination of this weld indicates that it had been almost completely cut. At this point the structure started to move in a southerly direction. The structure struck the boom of the crane. The boom broke and struck the basket of the manlift that Employees #1 and #2 were working from, killing them. The boom also hit a second manlift. The worker in that lift sustained a broken leg. As the structure collapsed, it fell onto the crane trapping the operator. The crane operator sustained serious injuries to his legs.

On December 5, 2008, Employee #1 was dispatched to the site to perform normal maintenance on the building's boiler equipment. Two domestic heating boilers and three comfort heating boilers were located in the room. Employee #1 was working alone in the room. An employee of a cleaning service entered the boiler room at approximately 10:00 a.m. to get a ladder and observed that Employee #1 was sweating profusely and the room was extremely warm. At 11:00 a.m. an employee of the building management company tried to reach the victim by phone and did not receive a response. Between 11:30 a.m. and 12:00 p.m. on December 5, 2008, the victim's supervisor arrived at the site (also, after trying to reach him by phone) and found the door to the boiler room locked. At approximately 12:00 p.m. Employee #1 was found unresponsive in a boiler room of a condominium complex. Employee #1's supervisor reported that one of the three comfort heating boilers was operating. When the supervisor obtained the key to the room, he found Employee #1 sitting on the floor leaning against a box unconscious. Employee #1 was pronounced dead at 12:25 p.m. at the scene. The medical examiner called the fire department and requested that carbon monoxide measurements be taken in the boiler room. The fire department measured approximately 1,400 parts-per-million of carbon monoxide in the room. Exhaust dampers on two of the comfort heating boilers were observed by the contractor to be partially closed during troubleshooting following the accident. This included the damper on the boiler that was operating when Employee #1's supervisor entered the boiler room. Following an autopsy, the medical examiner declared Employee #1 died of carbon monoxide intoxication.

The employee died of carbon monoxide poisoning on January 28, 2008. The autopsy reported the death occurred as a result of acute carbon monoxide poisoning. Acute cocaine intoxication was a significant condition reported in the autopsy report. The employee was responsible for the maintenance of the equipment at the car wash. He was called in to work on Sunday evening to fix some of the equipment. Two policemen from the local police department removed the unresponsive employee from the end of the 30' X 8' room, opposite the entry door after being notified by an employee. Surveillance video footage showed the time the employee entered the room. The employee was removed from the room by the two policemen approximately 95 minutes after the employee entered the room. The police reported that 2 tool kits were opened on top of some drums of car wash chemicals. It appeared the employee was working on the car wash equipment. The sources of the employee's exposure may include a defective exhaust system for one of the boilers in the room, lack of make-up air and defective heat exchanger on a room heating unit in the equipment room. Two Raypak boilers were housed in the equipment room. One of the boilers was used to heat water for the water used in the automatic car wash bays and the other boiler was used to heat water for the floors in the automatic car wash bays. One of the boilers, Raypak 724 WP-B, Serial Number 0988106022 had several cracks in the top and side panels and the draft hood. Initial carbon monoxide measurements made by the local fire department indicated 0 ppm carbon monoxide in the room. However, the boilers had not activitated and the room was ventilated with the entry door open when the measurement was made. The gas company made a carbon monoxide measurement when the boiler (with the cracks) was activated. The measurement was approximately 1100 ppm of carbon monoxide at one of the cracks. The employee's carboxyhemoglobin level was 42.7after he arrived at the hospital. His exposure to carbon monoxide based on the carboxyhemoglobin level was calculated to be approximately 258 parts per million (ppm) as an 8-hour TWA, which is 5.15 times the PEL of 50 ppm.

This documentation may include, but is not limited to, evidence of the purchase or repair of the equipment, photographic or video evidence of abatement, or other written records. Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to the hazard of burns and bodily injury from the hot ash and steam from leaking or ruptured pressure-retaining items. The following conditions contributed to the existence of the hazard: a) Location Boiler House, Unit #3: On or about November 6, 2007 Dominion Energy New England operated a pressurized coal fired Babcock & Wilcox that was insufficiently inspected and examined in the lower vestibule/dead air space which contains steam at approximately 600 Degrees Fahrenheit under 1000 psig. Three employees were fatally injured on November 6, 2007, when the boiler tubes ruptured in the lower vestibule/dead air space. * The lower vestibule/dead air space had not been entered and inspected in over9 years. No appropriate testing had been preformed to determine the conditions in the lower vestibule/dead air space in that length of time. * Ash was allowed to accumulate in the lower vestibule/dead air space over a long period which does not allow for entry into and inspection of that area. Among other methods, feasible means of abatement would be to: 1. Conduct Operation, Care/Maintenance, and Inspection of power boilers following the most recent National Codes such as ANSI/NB-23, ASME Section 7 Care of Power Boilers and guidance from Electric Power Research Institute and the manufacturer, Babcock and Wilcox. Including cleaning out the ash and debris from the vestibule/dead air space to allow for the inspection. 2. Determine a lower vestibule/lower dead air space inspection interval based on sound engineering principles and scientific data. 3. Install alarm system associated with power boiler operating parameters (eg., feed water make-up, electrostatic precipitator load/current changes, boiler pH, furnace pressure, boiler sodium and leaks in vestibules). 4. Install Leak Acoustic Monitoring system in vestibule
