(1) Firstly, check whether the oxygen pressure gauge is intact and sensitive, whether the indicated pressure is correct, and whether the operation is safe.

(2) When inflating an oxygen bomb, the pressure must be slowly increased until the specified pressure is reached, and then maintained for 0.5-1 minutes.

(3) Do not come into contact with grease when using oxygen.

(4) Oxygen bomb oxygenation should be carried out according to the specified pressure, and the oxygenation pressure should not be too low or too high.
