- 21. System Under Operations This tag is to be used on equipment to be locked out that is no longer under the control of graves. The purpose of the tag is to identify: To graves employees that the lock and tag contained on the equipment belongs to the owner. To owner employees that graves employees MAY be effected by a change in the LOTO status. The tag is only placed with authorization of the system operator.
- 22. System Locked Out This is the standard LOTO tag. It is to be placed on most LOTO requests.
- 23. System Under Test This tag is to be placed on equipment that is or may be energized by testing employees
Editor's Notes
- #2 I. Speaker’s Notes: Today’s session is on OSHA’s Control of Hazardous Energy Standard, or “lockout/tagout.”
- #3 I. Background for the Trainer: Discuss the types of equipment the company has that may need to be locked out. Ask if anyone has had an incident or near miss when equipment inadvertently started.
- #4 I. Speaker’s Notes: This program is required by federal law. All employees are affected by lockout/tagout. Any employee who operates equipment is an “affected” employee. Any employee who maintains or services equipment is an “authorized” employee. Training must be provided for authorized employees initially and at least annually.
- #6 I. Speaker’s Notes: LOTO devices must be able to withstand the environment in which they are used. They should also be standardized according to color, size, or shape and should be substantial enough so that they cannot be accidentally removed. To be identifiable, they should have a legend that states phrases such as Do Not Operate, Do Not Start, Do Not Energize, etc.
- #7 I. Speaker’s Notes: There are many different types of energy sources that may need lockout/tagout. Do not overlook any potential source of energy. Many sources are invisible. A job hazard analysis can help identify energy sources. Make sure any and all sources of energy can be effectively isolated.
- #9 I. Speaker’s Notes: This slide lists when lockout/tagout must be used. If you are unsure to what equipment LOTO applies, perform a hazard analysis. Make sure that all sources of energy are considered. Do not under any circumstances jeopardize an employee by not requiring LOTO—when in doubt, lock it out!!
- #10 I. Speaker’s Notes: If any of these occur, the equipment must be locked out. If a guard is removed from a piece of equipment, it should be locked out. Basically, any time an employee could be injured by the piece of equipment, it should be de-energized and locked out.
- #11 I. Speaker’s Notes: No energy means no need for LOTO. If routine adjustments such as those made to a printing press must occur, then the equipment does not have to be locked out. However, it is a good idea to have a second employee nearby a disconnect to shut down the equipment while the other employee works on it. Cord-controlled devices do not require LOTO because it is assumed that for these items, the person performing the repair has control of the plug. Companies do make lockout devices for the male end of an electrical plug. It is always a good idea to use these as needed. Hot tap operations that could conceivably shut down a plant (e.g., boilers) are not subject to LOTO if they will adversely affect the operation of the plant as a whole.
- #12 I. Background for the Trainer: Distribute examples of these types of procedure. II. Speaker’s Notes: Procedures for appropriate lockout should be documented. It is helpful to post these procedures at the equipment location. These procedures can follow any format that is pertinent to your company. Using these procedures allows for consistency throughout a facility.
- #13 I. Speaker’s Notes: There are two categories of employees covered by 1910.147: 1. Affected employees 2. Authorized employees Affected employees can be almost anyone in a facility, except office workers. An affected employee can have a significant impact on authorized employees if the affected employee starts the equipment prior to the completion of the work by the authorized employee.
- #15 I. Speaker’s Notes: It is important that a company lives up to its regulatory responsibility. LOTO is a major cause of industrial fatalities and must be taken seriously. If you intentionally violate LOTO rules, appropriate disciplinary actions will be taken to avoid future incidents. Annual reviews will be conducted to ensure that the written LOTO program is followed.
- #16 I. Speaker’s Notes: Since affected employees can impact the authorized employees, it is imperative that they follow these rules. Affected employees should not be ultimately responsible for the placement of locks and tags unless they are also working on the equipment. The more that an affected employee knows about the equipment that is being locked out, the safer the lockout operation will be. Proper training is of the utmost importance.
- #17 I. Speaker’s Notes: Because authorized employees are in harm’s way, they must follow all appropriate procedures to ensure their own protection. If a device cannot be physically locked, the buddy system should be used to ensure that equipment remains de-energized. A second person can keep the emergency stop button or disconnect employed. The tag should be located as close as possible to the control panel so that anyone who tries to operate the equipment is aware of the potential danger.
- #19 I. Speaker’s Notes: OSHA spells out specific training requirements for LOTO. Every employer is required to provide training in accordance with these regulations. Probably the single most difficult aspect of training is the retraining function, both when deficiencies are noted and on an annual basis for authorized employees.
- #20 I. Speaker’s Notes: Remember that failure to lockout equipment is a leading cause of injuries and fatalities in industry. Employees must really stay on their toes and avoid shortcuts that could cost them their lives. Ignorance of LOTO procedures cannot be tolerated under any circumstances. Simply put, the program must be in place, the training must be conducted, and evaluations for effectiveness must follow.
