How to Properly Conduct Confined Space Atmospheric Tests

This 2 minute safety training video covers: How to determine the oxygen content, what is the measurement of a safe oxygen content, how to detect the presence of flammable gases, what are the flammables commonly found in the air of confined spaces, how to identify toxic contaminants vapors and dusts, what are the confined space atmospheric hazards and what are the three basic atmospheric tests.

65% of fatalities in confined spaces have to do with hazardous atmosphere inside the space. Let's say you enter a confined space, but there isn't enough oxygen in the atmosphere just to sustain you, within minutes your heart rates going to go up, you'll start to feel weak, your judgement will be impaired, you'll begin to lose motor skills, you may experience nausea and vomiting. Finally, you'll pass out and if you don't get oxygen right away, you'll die.Even the area just outside a confined space can be oxygen deficient. So don't even break the plane of the opening without following proper confined space entry protocol. Just as two little oxygen is a huge hazard, so is too much oxygen. When too much oxygen gets in the atmosphere, it can cause combustible materials to ignite very quickly.
