From the assessment, i will be possible to reveal potential threat channels and in it acquire openness that will enable us to devise safety and precautionary measures to ensure success of our mega project. Tis stage is necessary since it determines the approval or denial of the project proposal by the Hong Kong construction and explosives authorities. Te analysis is highlighted below, wth regards to the type of risk posed by the explosives that will be stored in the magazine and transported to the blasting sites; Tis is used in general blasting, qarrying, ad mining.
I has a 0.96 kg equivalence of TNT per 1 kilogram of emulsion. I is a detonator sensitive emulsion, maning it does not require boosters to detonate it. A such, is handling requirements are quite high (Persson, Hlmberg &Lee 1993, pThis is an alternative explosive to cartridged emulsion in rock excavation through blasting. I is however used in tunnel blasting. I is sensitized by adding a gassing solution of citric or acetic acid to it. I is then directed to the charging a delivery pump.
Util it is pumped to the delivery hose, i is not explosive. Aain, i has to be detonated using a detonator and a small booster (Persson, Hlmberg & Lee 1993, pThese are the minute devices used in safely initiating blasting of explosives in a systematic (controlled) manner. Te ones to be used in this project are shock tube and non-electric detonators. Tey usually contain the most sensitive explosives but again, tey are made in a way that their handling poses minimal risks. I addition, teir is to absorb the explosions in case of accidental detonation.
Tis is a thin and flexible tube that has an explosive core. Adetonating cord contains compressed powder PETN explosive. I has an effect similar to a detonator along its entire length and is used to deliver detonations to the explosives or boosters from the control panels. Tey are initiated using blasting caps. Blk explosives require more than just the small quantities of explosive contained in detonators. A such, pimers or boosters are used. Bosters contain PETN and TNT to create Pntolite however requires a detonator to initiate explosion (Persson, Hlmberg & Lee 1993, pSeveral theories of safety and risk management can be. ..
