Tailgate Safety Talks
Compressed Air Safety
This Tailgate Talk is part of the NLTAPA collection.
Compressed air is often misjudged and not recognized as a hazard because people think of air as harmless.
Air forced into body tissues through skin can cause an air embolism (air bubbles in the bloodstream) which can be fatal if it reaches the heart, lungs, or brain.
Inflation injuries of the intestine can be caused by air being directed at private body areas. A worker in the U.K. died of injuries sustained through horseplay with a compressed air hose. The act of horseplay can be deadly!
Air blown into the mouth at only 5 PSI can rupture the esophagus or the lungs.
Eye and ear injuries can occur from a blast of air or flying particles. These types of eye and ear injuries can cause partial or total loss of sight and hearing.
The sound from a compressed air hose can reach 120-130 dB which is well above OSHA’s 90dB permissible exposure limit.
40 PSI can blow out an ear drum from 4 inches away and possibly cause brain damage.
As little as 12 PSI can blow an eye out of its socket!
Flying particles can cause cuts and bruises to any part of the body.
Hoses and lines should be rated to meet the maximum operating pressure of the equipment.
Always wear proper Personal Protective Equipment:
Safety glasses with side shields and a face shield if needed
Respiratory protection, depending on the material(s) being worked with
Normal work clothing is not protection against compressed air.
If you must clean with compressed air, do not use air that is set above 30 PSI. You must also have effective chip guarding and proper PPE (OSHA standard 1910.242(b)).
NEVER USE COMPRESSED AIR TO CLEAN CLOTHING OR HAIR!
NEVER POINT COMPRESSED AIR AT YOURSELF OR ANOTHER PERSON!
Go through the manufacturer’s safety recommendations in the air compressor’s safety manual and read and understand the maintenance requirements for the compressor.
