OSHA / General Industry

OSHA air quality standards need to be met for any industry using compressed breathing air, for the safety of the employees. The AirCheckKit™ helps you comply with the 1st item of OSHA’s 14-point Checklist for Breathing Air Quality and Use. We can test the compressed air quality of your air supply to assure that it meets Grade D breathing air requirements. Since OSHA doesn’t state what frequency you need to test or even how many locations need to be tested, we will provide assistance there too.

General Industry Compressed Air Quality

Easy Compliance with the #1 item on OSHA’s Checklist

Compressed air is used in a variety of industries including welding, sandblasting, spray painting, chemical spill cleaning and more. Some examples of when compressed breathing air should be used include but are not limited to the following examples:

  • If your employees work in situations where the level of oxygen is insufficient, or potentially insufficient.
  • If your employees are potentially exposed to harmful levels of hazardous gases or vapors.
  • If your employees are exposed to other potential respiratory hazards, such as dust, mists, fumes, sprays, and other airborne particles.

The 14-point Checklist and other useful OSHA documents are available in our Standards & Specifications section.

Since each company has unique requirements; we will work with you to package an AirCheckKit™ to meet your specific needs. Compressed air testing is what we do! You can request a brochure or call to discuss your low pressure and high pressure breathing air testing needs. Our AirCheck Team of Experts is available, knowledgeable and eager to assist you with any of your air compressor testing questions. Just give us a call! 1-800-247-1024
