Confined Space Atmospheric Testing
Program length: 18:00

Nine of every ten confined space fatalities are the result of hazardous atmospheres. Confined Space Atmospheric Testing will demonstrate the basics and importance of proper atmospheric testing techniques for confined spaces.

Identifying Confined Spaces

OSHA defines a confined space as any space that:

  • Is large enough for a person to enter and perform work in
  • Has a limited opening for entry and exit
  • Isn’t intended for continuous human occupancy.

Any space that contains serious hazards that could cause death or serious injury must be classified as a permit-required space.

Identifying Atmospheric Hazards

Atmospheric hazards present in confined spaces are oftentimes odorless and invisible to the naked eye. Proper identification of hazards is paramount in determining appropriate safeguards. Confined Space Atmospheric Testing will breakdown the three main categories of hazards:

  • Unsafe oxygen levels (either oxygen deficient or oxygen enriched)
  • Flammable gases
  • Toxic vapors and/or toxic dust particulates.

Specialized equipment and procedures are required to detect all three of these potential dangers.

Testing for Atmospheric Hazards

Before ANY entry into a confined space, the atmosphere inside must be tested for hazards using a calibrated direct-reading instrument. Results must be noted on the entry permit. Confined Space Atmospheric Testing will show you how to employ proper Evaluation Testing to determine procedures and what equipment to use.
