20 cards
- What work does 29 CFR 1910.147 cover?
- Servicing and maintenance where an unexpected startup, energizing or release of stored energy could injure employees.
- What three parts make up an energy control program?
- Energy control procedures, employee training and periodic inspections.
- What is the difference between an authorized and an affected employee?
- Authorized locks or tags out and does the servicing; affected runs the machine or works in the area.
- If an energy isolating device can take a lock, must the program use lockout?
- Yes, unless the employer shows that tagout gives full employee protection.
- If a tag is used on a device that can take a lock, where does it go?
- At the same spot the lock would go, with proof that tagout is as safe as lockout.
- Since what date must new or rebuilt machines have isolating devices that accept a lock?
- Since January 2, 1990, for new, replaced or majorly repaired machines.
- What must a written energy control procedure spell out?
- Its intended use; steps to shut down, isolate, block and secure; how devices go on, come off and transfer; and how to verify.
- When may an employer skip documenting a procedure?
- Only when all eight listed conditions exist, such as a single energy source and no stored energy.
- What four qualities must lockout and tagout devices have?
- Durable, standardized, substantial and identifiable.
- Standardized in what way?
- In at least one of color, shape or size; tags also in print and format.
- How strong must a tag's attachment be?
- Non-reusable, self-locking, attached by hand, with at least 50 pounds unlocking strength, like a one-piece nylon cable tie.
- What must a tag say?
- It warns of the hazard with a legend such as Do Not Start, Do Not Open, Do Not Close, Do Not Energize or Do Not Operate.
- How often is the periodic inspection, and who does it?
- At least once a year, by an authorized employee other than the ones using that procedure.
- What does the inspection certification record?
- The machine, the date, the employees included and the person who inspected.
- What training does each authorized employee receive?
- How to recognize hazardous energy sources, the type and magnitude of energy on site, and how to isolate and control it.
- What must all other employees in the area learn?
- About the procedure and that they must never try to restart a locked or tagged machine.
- What is the main limit of a tag?
- It is only a warning: it gives no physical restraint like a lock and can create a false sense of security.
- When is retraining required?
- When job assignments, machines or processes with new hazards, or procedures change, or when gaps show up.
- Who may apply lockout or tagout?
- Only the authorized employees who are doing the servicing or maintenance.
- Which does OSHA consider safer, lockout or tagout?
- Lockout devices: OSHA considers them more secure and more effective than tags.
