Which of the following is required before employees enter a permit-required confined space?
Correct Answer
D) Air monitoring and entry permit
OSHA requires atmospheric testing, a written entry permit, and proper safety procedures before entering permit-required confined spaces. This ensures the space is safe for entry and work.
Why This Is the Correct Answer
OSHA's Permit-Required Confined Space Standard (29 CFR 1910.146) mandates that before any employee enters a permit-required confined space, the atmosphere must be tested for oxygen levels, flammable gases, and toxic substances. A written entry permit must be completed that documents the safety measures, atmospheric testing results, and authorized personnel. This comprehensive approach ensures worker safety by identifying and controlling hazards before entry occurs. Air monitoring and the entry permit are the two fundamental requirements that cannot be bypassed.
Why the Other Options Are Wrong
Option B: Safety meeting only
While safety meetings are important for training and communication, they alone are insufficient for permit-required confined space entry. OSHA specifically requires atmospheric testing and a written entry permit, not just a safety meeting. A safety meeting cannot verify that the atmospheric conditions are safe or document the specific safety procedures for that particular entry.
Option C: Supervisor notification
Hard hats and safety glasses are basic PPE that may be required, but they do not address the primary hazards of confined spaces such as oxygen deficiency, toxic gases, or flammable atmospheres. OSHA's confined space standard requires much more comprehensive safety measures including atmospheric testing and entry permits before any entry can occur.
Memory Technique
Think 'AIR PERMIT' - you need to test the AIR and get a PERMIT before entering any confined space that requires a permit.
