Question

which of the following statements about cylinder placement are true? select all that apply. cylinders containing oxygen or acetylene shall not be placed in confined spaces cylinders should be placed as far away as possible from the welding or cutting operation when in use, fuel gas cylinders should be placed with the valve end up if you need to review this content, it can be found in the fire prevention module of the welding & cutting topic.

Explanation:

• Cylinders with oxygen or acetylene in confined spaces pose risks (e.g., gas accumulation).
• Placing cylinders away from welding/cutting (reduces heat - related hazards).
• Fuel gas cylinders valve - end up (ensures proper gas flow, prevents liquid fuel issues).

Answer:

All the statements are true. So, "Cylinders containing oxygen or acetylene shall not be placed in confined spaces", "Cylinders should be placed as far away as possible from the welding or cutting operation", and "When in use, fuel gas cylinders should be placed with the valve end up" are correct.
