Correct Answer
A. Before an employee enters a permit confined space, the internal atmosphere shall be tested for oxygen content, potential toxic air contaminants, flammable gases and vapours.Explanation
This statement is true because before an employee enters a permit confined space, it is necessary to test the internal atmosphere for various factors such as oxygen content, potential toxic air contaminants, flammable gases, and vapors. This is done to ensure the safety of the employee and to identify any potential hazards that may be present in the confined space.Rate this question:

When confined space entrance covers are removed, the opening shall be guarded prior to removal by (select all that apply);
-
Railing and/or Signage
-
Temporary Cover
-
Temporary Barrier
-
OSHA Regulated Board Stretchers
-
Proper testing activities to ensure compliance.
Correct Answer(s)
A. Railing and/or Signage
A. Temporary Cover
A. Temporary BarrierExplanation
When confined space entrance covers are removed, it is important to guard the opening to prevent accidents or unauthorized access. Railing and/or signage can be used to clearly indicate the danger and restrict entry. A temporary cover can be placed over the opening to prevent falls or objects from falling into the space. A temporary barrier can also be used to physically block access to the opening. OSHA regulated board stretchers and proper testing activities are not directly related to guarding the opening and are therefore not applicable in this situation.Rate this question:
