What Is an Explosion?
An explosion is defined as the sudden and violent propagation of high levels of thermal energy, light, combustion gases, sound, and pressure through the air resulting from the ignition of explosive substances in solid, liquid, or gaseous form, or of environments containing dust clouds, for various reasons. Explosion-proof electrical equipment must be used in explosive environments.
Explosion;
- Explosive mixture,
- Oxygen,
- It is possible when "ignition energy"—such as a spark, heat, an open flame, or static electricity—is present at the same time.
| Industry | Explosion Hazard |
 |
Chemical Industry:
Due to the flammable gases, liquids, and solids used or processed in various operations within the chemical industry, explosive mixtures or atmospheres may form during these processes. |
 |
Landfill Gas and Waste Disposal:
Flammable gases may be released during the storage or burial of waste or landfill gas. To prevent potential ignition and uncontrolled gas emissions, the necessary technical precautions must be taken. These flammable gases can accumulate in poorly ventilated tunnels or cavities. |
 |
Thermal Power Plants:
Although the likelihood of a mixture of lump coal and air creating an explosive atmosphere is low, the pulverized coal dust generated during conveyor transport, grinding, and drying poses a risk of creating an explosive atmosphere (dust-air mixture). Care must be taken regarding the spontaneous combustion properties of coal and coal dust. |
 |
Waste Disposal Sector:
Gases generated at wastewater treatment plants can create an explosive atmosphere (a gas-air mixture). |
 |
Natural Gas:
A natural gas leak can create an explosive atmosphere (a mixture of gas and air). |
 |
Wood Industry:
Wood dust generated during woodworking and in the furniture industry can create an explosive atmosphere (a mixture of dust and air) in locations such as silos, filters, or exhaust systems. |
 |
Paint shops:
Explosive atmospheres (gas-air mixtures) can form in paint spraying operations or in factory painting departments due to the mixing of solvent vapors with air. |
 |
Agriculture:
In biogas production facilities, an explosive atmosphere (gas-air mixture) may form as a result of gas release or leakage. |
 |
Pharmaceutical Industry:
Solvents used in the pharmaceutical industry can create explosive atmospheres (gas-air mixtures). In addition, active and excipient ingredients can create explosive atmospheres (dust-air mixtures) and cause dust explosions. |
 |
Refineries:
Explosive atmospheres can form in refineries due to hydrocarbons. |
 |
Recycling Facilities:
During waste recycling, containers, drums, boxes, or cans containing explosive gases or flammable liquids can create an explosive atmosphere (gas-air mixture). Additionally, an explosive atmosphere (dust-air mixture) can form due to paper or plastic dust. |
 |
Metal Industry:
During metal production, explosive metal dust may be released from the surfaces of the metals being processed or shaped. When this dust accumulates in collection systems or exhaust hoods, it can create an explosive atmosphere (a dust-air mixture). |
 |
Food Industry and Animal Feed:
When dust is collected in filters or exhaust systems during the storage, transport, or processing of grains and sugar, an explosive atmosphere (dust-air mixture) may form. |
