A maintenance technician must enter a below-grade sewage ejector pit with limited entry and potential hydrogen sulfide. How should this space be classified?

Answer: Permit-required confined space

A confined space with a potential hazardous atmosphere meets OSHA's definition of a permit-required confined space.

When testing the atmosphere before confined space entry, in what order should hazards be tested?

Answer: Oxygen, flammables, toxic gases

Oxygen is tested first because combustible gas meters need adequate oxygen to read accurately, followed by flammables and then toxics.

Catastrophic consequences can make even low-probability hazards a high priority for mitigation.
