What must entry supervisors verify before allowing entry into a permit space?

The correct answer emphasizes the critical role of verifying all test results, particularly atmospheric tests, before allowing entry into a permit space. This is essential for ensuring the safety of workers entering potentially hazardous environments.

Atmospheric testing typically involves measuring levels of oxygen, flammable gases, and toxic substances. Without verifying these test results, there could be serious health risks, such as asphyxiation, fire, or exposure to harmful chemicals. The entry supervisor must ensure that all necessary tests are conducted according to established safety protocols, which provides a baseline assessment of the environment before personnel enter.

Inadequate verification, such as relying solely on verbal confirmations or past entry evaluations, would not provide a current assessment of the space’s conditions, potentially exposing workers to unnecessary dangers. Moreover, the assertion that entry supervisors are not required to verify any tests is misleading, as the verification process is a fundamental component of ensuring workplace safety and compliance with safety regulations.
