What is an explosive chemist?
The Explosive Chemist/Analyst is a person who receives, examines, and analyzes evidence, interprets results, writes reports and testifies to findings concerning casework. The qualified Explosive Chemist/Analyst may technically or administratively review other analyst’s explosives reports.
What causes explosions in chemistry?
Chemical explosions are caused by either decomposition or combination reactions that produce large amounts of extremely hot gas, which expands rapidly and increases pressure. The large amount of hot gas essentially forms shock waves, creating an explosion which can have shattering effects.
What are the main effects of an explosion?
The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.
What is the importance of knowing about the different types of explosives?
Each type of explosion can be equally devastating and serious, causing unprecedented harm to the surrounding people, atmosphere and infrastructure. Therefore, understanding different types of explosions and how they occur is important.
What is the best description of an explosive?
An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
What do you mean by explosive substance?
1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.
What is the chemistry of an explosion?
Chemistry of Explosives. Explosives are chemical mixtures or compounds that, when subjected to heat, impact, or shock, are capable of undergoing a rapid decomposition that releases heat and gases, which, in turn, expand to form high pressures.
Is it possible to make your own homemade explosives?
NO. Don’t ever, ever, EVER try to make homemade explosives! It’s not as simple as knowing the ingredients. The recipe for bread is flour, yeast and water. If you just mix them together without knowing what you’re doing you won’t get bread.
What are the characteristics of explosive materials?
EXPLOSIVES DEFINITIONS 1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.
