Question

under what circumstances can cylinders containing oxygen or acetylene be placed in confined spaces? select the best option. when the supervisor has approved it when there is a fire watch present when there are extinguishing agents nearby oxygen or acetylene cylinders should not be placed in confined spaces

Explanation:

Oxygen and acetylene cylinders are highly flammable and pose significant safety risks. Confined spaces restrict ventilation and increase the likelihood of gas accumulation, which can lead to explosions or fires. Even with a supervisor's approval, a fire watch, or extinguishing agents nearby, the inherent danger of confined spaces makes it unsafe. Safety protocols generally prohibit placing such cylinders in confined spaces.

Answer:

Oxygen or acetylene cylinders should not be placed in confined spaces
