What is the effect of fire and explosion?
Devastating effects The effects of accidental fires or explosions can be devastating in terms of lives lost, injuries, damage to property and the environment, and to business continuity. Working with flammable liquids, dusts, gases and solids is hazardous because of the risk of fire and explosion.
What are the main effects of 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 explosion effect?
Explosion effects generally include those of overpressure, thermal effects, energized projectiles (fragments, debris, and missiles), ground shock, and cratering. Although for larger explosions, ground shock can result in damage to underground structures and utilities.
What is fire explosion?
A fire occurs when there is chemical reaction of a substance (fuel) combining with an oxidizer to release energy in the form of heat or light. An explosion is a violent release of energy caused by a physical or chemical reaction. It is accompanied by a rapid increase in pressure and usually temperature.
What are the causes of explosions?
What Causes Explosions? An explosion is a rapid expansion of gases. Many explosions occur when gases are exposed to a source of heat- such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions.

How does explosion affect the environment?
Explosive weapons can devastate a landscape. They can reduce buildings to toxic rubble and destroy long-cherished trees. They can contaminate the soil for decades and cause poisons to leach into once healthy rivers. They can decimate ecosystems and disturb the harmony of nature.
What are the secondary effects of explosion?
Primary blast injuries affect the lungs, eyes and brain. Secondary blast injury: These are injuries caused by the debris from the explosion, which penetrates and cuts the skin, creating harmful wounds. Secondary blast injuries are among the most common injuries following an explosion.
What are the 4 types of blast injuries?
The four basic mechanisms of blast injury are termed as primary, secondary, tertiary, and quaternary (Table 1).
What reaction causes explosions?
One more important section related to combustion is the “explosive” chemical. Explosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases. It is the sudden buildup of gas pressure (see products above) that constitutes the nature of an explosion.
What causes an explosion?
An explosion is a rapid expansion of gases. Many explosions occur when gases are exposed to a source of heat- such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions. Some chemicals can even explode if exposed to air or water.
