Electronic Detonators

Electronic Detonators form a modern fully programmable high strength detonators. Each detonator contains a circuit board that can be programmed to initiate at a precise time within a firing sequence. Detonators are individually programmed via the use of a handheld tagger and initiated via a bespoke blasting box.

EPC-UK supplies the DigiShot electronic detonator to the UK market. Electronic detonators can be used in a variety of applications including quarrying, mining, demolition and other specialist areas. the high strength detonator is suitable for initiating most priming charges. Complex firing patterns can be easily transferred to the detonators through the use of computer based software, when implemented properly the highly accurate initiation timings offer benefits in vibration control, fragmentation and general blast optimisation.

The digital firing system used for initiation means each firing circuit and individual detonator is tested and a record retained in the software prior to firing. The circuit can only be initiated by specialist firing equipment offering benefit in safety and security over traditional systems. The DigiShot system can be fired in a remote configuration offering improved control over the blast danger zone.

HAZARD IDENTIFICATION

Other Hazards After detonation, dust and fumes may be harmful by inhalation on repeated exposure by inhalation (lead poisoning).

Classification

Electric detonators are designed to explode with a substantial release of energy and should therefore be handled with care. Detonators must not be subjected to impact, friction, or exposed to heat or flame. There is a danger of high velocity penetrating shrapnel within a radius of ±10 m around a detonator. Detonators are explosive articles. Without packaging electronic detonators are classified Exp 1.1 H201 (explosive: mass explosion hazard).

As packaged for transport Digishot detonators may be Class 1.1B or Class 1.4S

FIRST AID MEASURES

First Aid – Eyes Unlikely unless detonator is fired. Obtain medical attention ASAP.

First Aid – Skin Not harmful unless detonator is fired. Treat for high velocity trauma, stop bleeding and obtain medical attention ASAP.

First Aid – Ingestion Not normal route of entry, but seek medical advice ASAP. Make physician aware of explosive properties of ingested material.

First Aid – Inhalation Unlikely unless detonator is fired. Remove patient from NO2 exposure to clean air and obtain medical attention. Administer oxygen if possible.

Most Important Symptoms and Effects, Both Acute and Delayed

Trauma due to high velocity shrapnel.

Indication of Any Immediate Medical Attention and Special Treatment Needed

Treat symptomatically.

Description of First Aid Measures


FIRE FIGHTING MEASURES

Extinguishing Media Do not fight the fire if it has reached, or if it will reach the detonators.

If fire may be prevented from reaching the explosives, water, carbon dioxide, extinguishing powders or alcohol resistant foams may be used as appropriate. Don’t use water if electrical equipment is involved.

- DO NOT ATTEMPT TO EXTINGUISH THE BURNING EXPLOSIVES! RISK OF EXPLOSION.

Try to remain calm and extinguish the fire before it reaches the product. In case of the risk of an explosion, do not attempt to extinguish the fire. Evacuate to a shelter located at least 300m away. Secure the site against unauthorized access.

Special Hazards Arising from Product

Evolves toxic fumes (hydrogen chloride and phosgene) from the PVC when heated to the decomposition temperature.

Advice for Firefighters Set up a safety perimeter.Do not personally intervene to stop a pyrotechnics fire.Whenever possible, measures should be taken to prevent the fire from spreading.After the fire has been extinguished, the site where it took place may only be entered after ascertaining that the entire area has cooled completely. Be aware of unexploded detonators in area. When intervening, wear special fire prevention equipment (respiratory device, helmet, etc.).

ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment and emergency procedures

Damaged or cracked detonators may be very sensitive to sources of ignition. Do not pick up or move damaged detonators. Shut off all possible sources of ignition. Evacuate the area and then inform the relevant authorities or responsible person immediately. In case of a transport accident, notify the local authorities / police, the transport company and supplier.

Environmental Precautions Not applicable.

Methods and material for containment and cleaning up

While undamaged detonators may be picked up, freed of loose contamination and carefully packed in suitable, preferably original, packaging. (Note any change of packing may affect the transport classification). Pyrotechnic materials spilled accidentally must be collected by authorised personnel, so that they can be disposed of and, if necessary, destroyed (see waste handling, Disposal Considerations).

Reference to other sections See Exposure Control/Personal Protection and Disposal Considerations.
