PRIMACORD

PRIMACORD detonating cords are flexible linear explosives with a core of PETN explosive encased in a textile outer jacket. PRIMACORD detonating cords are designed for use as trunklines and/or downlines in various mining, quarrying and construction applications.

 

APPLICATION RECOMMENDATIONS

 

• ALWAYS cut detonating cord with a sharp, non-sparking knife.

• NEVER attempt to cut detonating cords by abrasion or with a blow from a sharp or blunt object.

• ALWAYS use square knots to extend/join detonating cords that will propagate selfto-self. When connecting downlines to trunklines, always use a clove hitch knot and keep incoming and outgoing cords at right angles to avoid possibility of cut-offs.

• NEVER join PRIMACORD 1, 2 and 3 together with knots because it will not propagate self-to-self.

• ALWAYS use a detonating cord product, such as PRIMACORD 4Y or 4R or detonating cord with a greater explosive coreload as a trunkline to initiate PRIMACORD 1, 2 or 3.

• ALWAYS use a double wrap clove hitch knot to connect PRIMACORD 1, 2 and 3 detonating cord to the trunkline cord.

• NEVER allow trunklines and/or downlines to cross.

• Minimum recommended initiating detonator is a No. 8 strength.

• Minimum recommended cord initiator is a 3.6 g/m (18 gr/ft) detonating cord, such as PRIMACORD 4Y or 4R, or another detonating cord with an equal or greater explosive coreload.

 

TRANSPORTATION, STORAGE AND HANDLING

 

• PRIMACORD must be transported, stored, handled and used in conformity with all federal, state, provincial and local laws and regulations.

• For maximum shelf life (5 years), PRIMACORD must be stored in a cool, dry, well ventilated magazine. Explosive inventory should be rotated. Avoid using new materials before the old. For recommended good practices in transporting, storing, handling and using this product, see the booklet “Prevention of Accidents in the Use of Explosive Materials” packed inside each case and the Safety Library publications of the Institute of Makers of Explosives.
