OSHA Air Compressor Guidelines: Key Safety Rules

If you manage or maintain an air compressor in a commercial or industrial setting, following OSHA guidelines is critical. Staying compliant helps you avoid fines — and more importantly, keeps your team safe.

Here are the key OSHA safety rules you should know when operating air compressors.

1. Regular Inspections and Maintenance

OSHA requires compressed air systems to be regularly inspected and maintained to ensure safe operation. This includes checking safety valves, gauges, hoses, and other components for wear or damage.

2. Proper Pressure Relief Valves

Every pressure vessel (including receiver tanks) must have properly rated and functioning pressure relief valves. These valves prevent dangerous over-pressurization events.

3. Clearly Labeled Controls and Gauges

All control switches and gauges should be clearly marked and easily accessible. Employees should be trained to read and understand these controls to monitor system status safely.

4. Safe Air Nozzle Pressure

When used for cleaning, OSHA limits compressed air nozzle pressure to 30 psi unless it is equipped with a safety nozzle that prevents backpressure buildup. This reduces the risk of serious injury.

5. Personal Protective Equipment (PPE)

Operators using compressed air for cleaning or maintenance must wear appropriate PPE, such as eye and face protection, to guard against flying debris and sudden air bursts.

6. Training and Documentation

OSHA requires that operators receive proper training on compressor operation and safety. Documentation of training and maintenance activities should be kept up to date and accessible.

Stay Safe and Stay Compliant

Following OSHA guidelines isn’t just about avoiding penalties — it’s about protecting people and equipment. A safer shop or plant is a more productive one.
