Safety Wick

It is an explosive blasting accessory made up of a black powder core covered in paper, several layers of cotton thread, asphalt and a layer of PVC to guarantee impermeability, flexibility and resistance to abrasion. This accessory transmits a flame or fire, at a known and constant speed to initiate a common detonator, which explodes and is responsible for sensitizing the explosives that are in contact with it. It is used as a means of initiating detonator number 8 fixed at one of its ends. The safety fuse has a combustion time per linear unit required to protect the explosive person who initiates the blast. Sensitive under certain conditions to impact, friction, spark or fire.
