Question

what care should be taken while handling explosives? ​

Answer 1

Answer:

For example, heating a magazine has to be done in such a way as to not direct the heat onto the explosives but to keep their temperature constant. OSHA’s regulations are very specific (e.g., “The electric fan or pump used in the heating system for a magazine shall be mounted outside and separate from the wall of the magazine and shall be grounded.”), but the basic requirements are that the explosives must be:

dry and well ventilated;

as cool as possible and not exposed to serious changes of temperature;

protected from direct sunlight and flooding;

not exposed to excessive or constant vibration,

stored separately from blasting caps, electric blasting caps, detonating primers, and primed cartridges; and

accessible only to authorized workers who are competent, trained and use extreme care.

Magazines storing explosives (whether they’re buildings or containers) must adhere to a number of requirements:

Magazines are to be kept clean and orderly.

All explosives must be accounted for at all times through the use of records and logbooks. The oldest explosives must be used first because the quality of explosives can degrade over time; a rotation system that allows for this must be in place.

When opening or closing wood packages of explosives, a wood wedge and a fiber, rubber, or wood mallet must be used.

Magazine floors must be regularly swept (the sweepings must be properly disposed of) and kept clean and dry. Brooms and other cleaning utensils mustn’t have any spark-producing metal parts.

In the event of a fire breaking out and being in imminent danger of contact with explosives, no firefighting actions should be taken. Instead, all employees must be removed to a safe area. In addition, the fire area must be guarded to prevent anyone from entering it by accident or on purpose.

Smoking and open flames mustn’t be present within 50 feet of explosives and detonator storage magazines. This should be well understood by everyone, but sometimes people need reminding.
