Atmospheric testing is required for two distinct purposes:
Evaluation of the hazards of the permit space and verification that acceptable conditions exist for entry into that space. Evaluation Testing is done to determine what chemical hazards are or may become present in the space's atmosphere, and identify what steps must be followed and what conditions must be met to ensure that atmospheric conditions are safe for a worker to enter the space.
Verification Testing must be conducted before a permit space that may have a hazardous atmosphere can be entered. The testing is done to make sure that the chemical hazards that may be present are below the levels necessary for safe entry, and that they meet the conditions identified on the permit.
We have the experience and equipment to conduct such Atmospheric Tests in accordance with a Permit to Work or as a stand alone service.
