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 remove this comment, it can be found in the fire - prevention module of the welding & cutting topic.

Explanation:

1. Cylinders containing oxygen or acetylene are highly flammable and reactive. Placing them in confined spaces can be dangerous due to the risk of gas accumulation and potential explosion, so the first statement is true.
2. Welding and cutting operations generate heat and sparks. Keeping cylinders far away reduces the risk of ignition and explosion, making the second statement true.
3. For safety and proper functioning, when in use, fuel - gas cylinders should be placed with the valve end up to prevent liquid fuel from entering the regulator and causing problems, so the third statement is true.

Answer:

All of the above statements are true.
