What type of certification is required for handling explosives?
NPS PERSONNEL All persons handling, transporting or using explosives shall be certified (licensed). All certified blasters shall possess a current Standard Red Cross First Aid certification, or equivalent, and a current cardiopulmo- nary resuscitation (CPR) certification.
What is cap sensitive explosive?
“Cap Sensitivity” means the sensitivity of an explosive to initiation by a detonator. An explosive material is considered to be cap sensitive if it detonates with a No. 8 Test Detonator.
How many classes of explosives are there?
There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.
What is explosive management course?
COURSE: NATIONAL DIPLOMA IN EXPLOSIVES MANAGEM… Explosives technologies are widely used in mining, manufacturing and construction. This programme equips students to apply these technologies safely and cost-effectively by developing deep technical knowledge and advanced management skills.
What is the most powerful military explosive?
PETN is a powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive….Pentaerythritol tetranitrate.

Which explosive corrodes most metal?
HMTD
Which explosive corrodes most metal? Explanation: HMTD ( hexamethylene-triperoxide diamine) is an improvised explosives which corrodes most of metal because of the property of extremely sensitive heat, shock and friction also.
What is the difference between high explosives and low explosives?
“High explosives” detonate, whereas “low explosives” deflagrate or burn. A high-explosives detonation provides both shock, which fractures (or breaks) the rock, and force (in the form of gas products), which heaves and displaces the fractured rock.
What is the difference between high explosive and blasting agent?
High explosive (HE)= an explosive material that can be caused to detonate with a No. 8 blasting cap when unconfined; and Blasting agent (BA)= a mixture consisting of a fuel and oxidizer, intended for blasting but otherwise not an explosive (cannot be detonated with a No. 8 blasting cap).
What is the loading density of an explosive?
Loading Density. An explosive’s loading density (LD) is defined as the weight of explosive per unit length of borehole at a specified hole diameter. Expressed in pounds per foot, LD is computed as: LD (lbs/ft) = 0.3405 ρD2. where D is the borehole drilled diameter in inches and ρ is the explosive density in g/cm3.
What is a wet gel explosive?
Wet BA’s: Water Gels and Slurries. A water-gel or slurry explosive is a gelatinous aqueous solution that consists of an oxidizer, such as AN, and a fuel. Typically, the fuel will contain additional dispersed solid oxidizers, fuels, and sensitizers such as aluminum or other explosives.
