ASPHALT SAFETY Asphalt operations are extremely dangerous.Some of the factors that make this one of the most dangerous operations weundertake are:1. Heavy equipment associated with paving2. Chemicals that make up asphalt, tack and emulsions3. Traffic control
HAND TOOL SAFETY Rakes Hand TampersPush Broom Shovels
SOFT TISSUE INJURYMany activities during paving operations are done in a position to bring on soft tissue injuries. Stretching prior to starting work warms up muscles and stretches tendons helping to prevent or reduce an injury.
PERSONNEL SAFETY Raking techniquesStanceMove your feet as you rake instead of remaining anchored in one place.Keep your feet a shoulder-width apart as you move.Pull your rake in a backward direction, and move with the rake through yourhands while working.Avoid twisting your trunk or bending as you labor.Wear gloves to prevent blisters.Stretch periodically by leaning backward and then by raising both armsupward toward the sky.

PERSONNEL SAFETY Shoveling techniques1. Warm up your body before using a shovel to move materials. You can do stretchesor simply walk in place to get your heart pumping and to loosen tight muscles. Thiswill help to prevent sore muscles the next day and reduce the possibility of soft tissueinjury.2. Stand with your feet approximately shoulder width apart when attempting toshovel materials. This will help you maintain your balance and lessen the strain onyour back.3. Place your hands about 6 inches apart on the shovel handle and wear sturdy workgloves. This will give you more leverage and assist you in lifting the heavy materials.
PERSONNEL SAFETY Shoveling techniques4. Spray your shovel blade with a lubricant to help the material slideeasily off the blade.5. Squat with your knees bent and keep your back area straight whenyou are lifting the materials. Do not lift the materials with your backmuscles; allow your leg muscles to do the work.6. Dump the materials in front of you, if possible. If you must dump thematerials to your side, move your feet in order to do this. Avoidtwisting your body because this can result in back injuries.

HEAT ILLNESS INJURY PREVENTION Heat Exhaustion -Individuals with heat exhaustion tend to have symptoms such as:• profuse sweating• weakness• muscle cramps• headache• nausea• vomitingAs dehydration increases from the loss of body water, lightheadedness mayoccur and fainting may occur especially, if the affected individual stands upquickly.A low grade fever also may be present.
HEAT ILLNESS INJURY PREVENTION Heat Exhaustion -How is heat exhaustion treated?The affected individual should stop their activity and then move from the hotenvironment to a cooler environment. The person may be placed in the shade ortaken to an air conditioned. Clothes may be removed to help with air circulationacross the body. Misting the skin with cool water also helps by stimulatingevaporation and cooling the body.Rehydration is the next important step in treating heat exhaustion. Small sips ofwater, a mouthful at a time. Water, sports drink and other electrolyte replacementdrinks are reasonable options.Muscles cramps and pain may be treated with over-the-counter medications likeAspirin and Tylenol.
HEAT ILLNESS INJURY PREVENTIONHeat Stroke -Common symptoms and signs of heat stroke include:high body temperaturethe absence of sweatinghot red or flushed dry skinrapid pulsedifficulty breathingstrange behaviorhallucinationsconfusionagitationdisorientationseizurecoma
How do you treat a heat stroke victim?Victims of heat stroke must receive immediate treatment to avoid permanentorgan damage. First and foremost, cool the victim.Get the victim to a shady area, remove clothing, apply cool or tepid water to theskin (for example you may spray the victim with cool water from a gardenhose), fan the victim to promote sweating and evaporation, and place ice packsunder armpits and groin.If the person is able to drink liquids, have them drink cool water or other coolbeverages that do not contain alcohol or caffeine.Monitor body temperature with a thermometer and continue cooling efforts untilthe body temperature drops to 101 to 102 F (38.3 to 38.8 C).Always notify emergency services (911) immediately. If their arrival isdelayed, they can give you further instructions for treatment of the victim
IF A PERSON SUFFERS HEAT STROKE NEVER LEAVE THEM ALONE!!! THEY MAY BE DISORIENTED. THE DIFFERENCE BETWEEN DISORIENTED AND DIZZY ARE DIFFERENT.A PERSON WHO IS DISORIENTED CANNOT ANSWER SIMPLE QUESTIONS SUCH AS: WHERE DO YOU LIVE? WHEN WERE YOU BORN? WHERE WERE YOU BORN? GET MEDICAL ASSISTANCE AS SOON AS POSSIBLE.
HEAT ILLNESS INJURY PREVENTION• INSURE THERE IS ADEQUATE WATER ON THE JOB AT ALL TIMES.• MAKE SURE EMPLOYEES HYDRATE OFTEN.• PROVIDE CLEAN DISPOSABLE ONE SERVICE CUPS.• CHECK WATER SUPPLY OFTEN TO INSURE IT DOES NOT RUN OUT.• SHADE NEEDS TO BE AVAILABLE FOR BREAKS. (POP UPS WORK GOOD IF THERE ARE NO TREES AVAILABLE). PROVIDE EQUIPMENT TO ASSIST IN PREVENTION: • HARD HAT SHADES • NECK COOLERS • BODY COOLING VESTS • MINERAL REPLENISHMENT DRINKS
MATERIAL SAFETY There is no current federal OSHA (Occupational Safety and Health Administration) existing occupational exposure limit (OEL) for bitumen fume in the U.S.Material Safety Data Sheets1. Train employees in the use of MSDS’s2. Follow the MSDS for the materials being used3. Know the proper PPE requirements as they are called out on the MSDSAsphalt Temperatures1. Asphalt is delivered at anywhere from 270 to 320 degrees2. This temperature will cause burns to skin and should be guarded against skin contact3. This temperature will dehydrate employees more rapidly
MATERIAL SAFETYAsphalt Fumes- Over a half-million workers are exposed to fumesfrom asphalt, a petroleum product used extensively in road paving,roofing, siding, and concrete work. Health effects from exposure toasphalt fumes include headache, skin rash, sensitization, fatigue,reduced appetite, throat and eye irritation, cough, and skin cancer.There are currently no specific OSHA standards for asphalt fumes.Exposures to various chemical components of asphalt fumes areaddressed in specific standards for the general and constructionindustries, such as personal protective equipment (PPE).
The complex chemical composition of asphalt makes it difficult toidentify the specific component(s) responsible for adverse health effectsobserved in exposed workers.Known carcinogens have been found in asphalt fumes generated atwork sites.Observations of acute irritation in workers from airborne and dermalexposures to asphalt fumes and aerosols and the potential for chronichealth effects, including cancer, warrant continued diligence in thecontrol of exposures.Partanen and Boffetta  recently conducted a meta-analysis ofstudies involving pavers and highway workers exposed to asphalt. Theirassessment did not find overall evidence for lung cancer risk amongpavers. Overall, the epidemiologic evidence for an association betweenlung cancer and exposure to asphalt in paving is inconclusive at thistime.
TRAFFIC CONTROL1. Obtain a traffic control plan completed by a traffic engineer2. While working within the traffic control area insure all employees are trained and aware of their surroundings.3. Set up approved traffic control equipment4. Use flaggers as needed
1. Keep heads on a swivel while working2. Be aware of truck and equipment movement within the closed traffic area3. Have a plan to move equipment and trucks in and out of closed traffic safely
Always use caution when setting up andtaking down traffic control devices.
PLAN, PREPARE AND EXECUTE. USE THE APPROPRIATE PPEAND EVERYONE GOES HOME HEALTHY!
