A person must hold a valid California Blaster’s License and must be physically present when performing, directing, and supervising blasting operations.

Note: the exception is persons 18 years or older and under the direct personal supervision of a licensed blaster.

Step 3

Reporting of Blasting Accidents

All blasting accidents affecting worker safety must be reported to the Division of Occupational Safety and Health (DOSH) within 24 hours.

Note: accidents involving a serious injury or illness must be reported to DOSH immediately but not longer than 8 hours.

Step 4

Storage of Explosives

Explosives must be stored in the proper type of magazine (see 5252 Table EX-1), 5251(a).

Step 5

Storage of Caps and Detonators

Caps and detonators must be stored in separate magazines away from other explosives.

Step 6

Transportation requirements are discussed in Subchapter 7 Article 115 (Index).

Step 7

Safety Rules for Blasting Operations

Safety rules for blasting operations are as follows:

-No smoking or open flames are permitted within 50 feet of explosives handling

-No source of ignition, except during firing, is permitted in areas containing loaded holes

-Only non-sparking tools are to be used for opening containers of explosives

-Explosives must be kept clear of electrical circuits by 25 feet

-Unused explosives must be returned promptly to the magazine

-Blasting mats must be used when flying material could damage property

-A tally sheet that records all movement of explosives must be kept at each magazine

-Holes may be loaded only after all drilling is complete

-No vehicle traffic should pass over loaded holes

-Loaded holes must be attended

-Workers must not try to quench an explosive’s fire

-Explosives at a blast site must be attended

-No one but the attendant(s), the loading/detonation crew, inspection personnel, and authorized supervisory personnel shall be allowed within 50 feet of the loaded holes
