FOR SAFETY SAK E
THE NO-PRESSURE APPROACH TO AIR COMPRESSOR SAFETY One of today’s most versatile tools operates based on a very simple principle: squeezing a volume of air into a smaller space dramatically increases its pressure. Air compressors produce highly pressurized air that can be used for everything from powering tools – like a jackhammer, or impact wrench – to blowing out irrigation lines. Pressurized air is remarkably powerful and, when used correctly, is very safe. The key to ensuring safe operation of air compressors is making sure that the operator has been properly trained and is familiar with the particular model that is being used. It’s important to read the operating manual and follow the proper steps for operation. In this article, we’ll review some of the best practices for safe compressor operation.
PRE-TASK PREPARATION Before using the compressor, verify that it is in good working order and has been properly lubricated. If necessary, check the oil level. If you need to add oil, be careful to avoid overfilling, or spilling oil on the compressor itself.

Verify that the air filter is clean, and that the air entering the compressor is fresh. If the filter appears to be dirty, replace it. Make sure that any moving parts have been guarded so that workers can’t come into contact with them inadvertently. Because some compressed air tools can generate static electricity, be sure that the compressor is properly grounded before using it where any kind of flammable or explosive vapors may be present. You should not use compressors that burn gasoline or diesel fuel indoors, and you always want to ensure that the exhaust from compressors is directed away from air intakes and windows. continued on page 18
