OSHA: Lockout
| Question | Answer |
|---|---|
| What does this standard cover? | the servicing and maintenance of machines and equipment in which the unexpected energization or start up of the machines or equipment, or release of stored energy could cause injury to employees. |
| When does this standard apply? | Applies to the control of energy during servicing and/or maintenance of machines and equipment. |
| Applies to equipment only if... | An employee is required to bypass a guard, is required to place any part of his body into an area on a piece of equipment at point of operation, or where an associated danger zone exists during a machine operating cycle. |
