Shock Tube Detonators Safety Sheet
The signal tube has an internal dusting of HMX and aluminium powder. The detonator has a lead azide and PETN charge
Detonators are classed as explosive.
a) Personnel handling explosives must be trained in their use.
b) Personnel should be trained in lifting/handling.
c) Avoid ingestion and contact with skin.
First Aid Measures
Fire Fighting Measures
Fires involving explosives must NOT be fought. An area of at least 300 metres around the fire should be evacuated and the site of the fire must not be approached until it is absolutely certain that the fire is out, if a detonation occurs within the mass, this may be transferred to other detonators.
Use water based extinguishers to prevent fire reaching detonators.
Accidental Release Measures
Spillages – Collect up articles, wipe carefully with clean, damp clothes, repack in paper bags and into cardboard boxes. Seal with glue or adhesive tape.
Should this not possible, the explosive should be destroyed in the manner described in U.I.E.”s leaflet “RECOMMENDED METHODS FOR THE DESTRUCTION OF EXPLOSIVES & ACCESSORIES”.
Handling & Storage
Detonators must be handled with care and not subject to naked flame, friction or shock. Smoking whilst handling explosives is forbidden. Keep product clean and free from contamination. Do not carry electric detonators in plastic bags and do not exert force on electric detonator lead wires or shock tube.
Static electricity, stray electric currents and use near CB radios and transmitters should be avoided with electric detonators. Explosives may only be stored in licensed premises.
Exposure Controls / Personal Protection
When handling detonators, personnel are advised to wear overalls and suitable gloves.
