Make sure safeguards are used when cleaning with compressed air.
You must use the following when cleaning with compressed air:
(1) Air pressure that has been reduced to less than 30 p.s.i. static pressure at the nozzle;
(2) Effective chip guarding.
Note: | 1. You may use air pressure greater than 30 p.s.i. if you use a nozzle with vents, holes, flaps or slots that will direct the air flow away from the tip of the nozzle and will reduce the air flow to less than 30 p.s.i if the nozzle becomes blocked. |
2. Effective chip guarding means any method or equipment that protects the eyes and skin of the cleaner and other workers from flying chips or particles. | |
3. Examples include: | |
a. A protective cone around the nozzle to protect the cleaner. | |
b. Barriers, baffles or screens to protect other workers. |
Reference: | Appropriate personal protective equipment (PPE) needs to be worn when cleaning with compressed air. See WAC 296-800-160 in the safety and health core rules. |
