Question

Which of the following tests is required before entry into a confined space?

A) Air quality testing
B) Visual inspection of the space
C) Noise level testing
D) Surface friction testing

Answer 1

The necessary test before entering a confined space is Air quality testing, which is crucial to prevent health hazards due to poor ventilation and potentially toxic atmosphere.

Step-by-step explanation:

The test required before entry into a confined space is A) Air quality testing. This is essential for ensuring the safety of individuals entering the space because it measures levels of oxygen, flammable gases, and potential toxic contaminants. Confined spaces can have inadequate ventilation which might lead to hazardous atmospheres, and therefore, air quality must be tested to prevent asphyxiation or other health risks.
