What causes bombs to blow up?

It is the rapid liberation of heat that causes the gaseous products of most explosive reactions to expand and generate high pressures. This rapid generation of high pressures of the released gas constitutes the explosion. The liberation of heat with insufficient rapidity will not cause an explosion.

How blasting can be effective explain?

Blasting can be classified as effective if additional processes in the rock mass lead to an energy release and a transition of the rock mass to a new stable equilibrium state occurs. In the selected longwall, every blasting for roof caving gave a positive effect.

What happens to the air when a bomb explodes?

The blast creates a large fireball and a mushroom cloud of dust and particles. When the cloud settles down, dust and particles containing radioactive materials fall back to earth. This is called fallout. Fallout can be carried by the wind and can contaminate the air, soil, food and water.

What are the negative effects of explosive materials?

These materials can penetrate walls, break windows and even cause structural damage. Heat from the explosion can affect the properties of building materials. This can cause materials to lose flexibility, which may contribute to progressive collapse. Heat from the explosion can also ignite fires.

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 precautions should be taken during blasting?

To ensure that workers can perform abrasive blasting tasks safely, employers should take the following safety measures:

• Secure the Environment. Eliminate tripping and falling hazards.
• Check the Blasting Equipment. Look for cracks and other damage.
• Ensure Protective Gear Is Available.
• Use Proper Cleanup Procedures.
