Sets out requirements for the safe use of explosives including the mixing, testing, initiation and firing of charges. The Standard also provides information on misfires as well as considerations such as ground vibration and airblast. Special topics including blasting in hot material, blasting under water and demolition by blasting are also included.

This Standard sets out requirements and precautions for the use of factory-made explosives and certain explosives mixed at sites. It does not apply to the following:(a) Explosives used in underground coal mines.(b) Safety ammunition and propellant powder.(c) Pyrotechnics including fireworks, rockets, fog signals or the like.(d) Purpose designed and manufactured military explosives.NOTE: This Standard should not be regarded as overriding statutory requirements, including licensing, but may be construed as a set of working rules to be used in conjunction with such requirements.NEW MATERIALS, METHODS AND
