Confined Space Hazards

One can t rely on one s comfort level to determine if a confined space is safe or not.

Confined space hazards. Osha uses the term permit required confined space permit space to describe a confined space that has one or more of the following characteristics. Large enough for an employee to enter and perform work 2. Confined space hazards presence of toxic gases inside vessels or pipelines in harmful concentrations. In many instances employees who work in confined spaces also face increased risk of exposure to serious physical injury from hazards such as entrapment engulfment and hazardous atmospheric conditions.

Has limited or restricted means for entry or exit 3. Common confined space hazards pits and trenches sewers and drains vats silos and tanks chambers and ducting unventilated or poorly ventilated rooms.
