Fire safety of magnesium alloy

1. The main disasters of molten magnesium alloy are:

l Magnesium alloy on fire

l Magnesium liquid sputtering

l Personnel burns

Do not use water to extinguish fire

Do not use Class A, B, C fire extinguishers

2. The correct extinguishing agent and its fire fighting procedures are as follows:

(1) Covering agent for magnesium alloy

l Usually fire in the furnace, use a covering agent to extinguish the fire in the initial stage of combustion or a small amount of burning.

l When using, dry the covering agent with a spatula or other tools and sprinkle it on the fire.

l Cut and throw the cover plastic bag directly to the fire, unless the fire is too large to be accessible.

(2) dry dry sand

l Dry or dry sand can be used to extinguish fires regardless of whether the fire has burned.

l Make sure the dry sand is dry before use.

l When using, use a shovel to spread the dry sand on the fire. The amount should be large and the coverage should be average.

l For magnesium chips, when the slag is extinguished, not only should it be covered and should be tumbling, so the fire extinguishing effect will be good.

(3) Metal fire extinguisher for magnesium alloy (D type fire extinguisher)

l The metal fire extinguisher cannot completely extinguish the burning magnesium, and the fire is controlled.

l Operate according to the method and procedure of using the fire extinguisher. The injection pressure should not be too large to blow away the burning magnesia to create a larger disaster range.

l Because the fire cannot be completely extinguished, after the fire is controlled, the embers must be batched, and a small amount of shovel should be moved to other safe places for further treatment.
