when are explosion proof lights required
We need to understand what explosion-proof lights are. In short, it is a lighting device that can work safely in potentially explosive environments. The design of such lighting fixtures can prevent internal sparks or high temperatures from coming into contact with flammable gases in the external environment, thereby avoiding explosions.

In what environment do we come into contact with situations that require the use of explosion-proof lights? Usually, this involves specific locations and industries. For example:
- Petrochemical industry: Refineries, chemical plants, oil depots, and other places often store and process large amounts of flammable chemicals. The air in these places may be filled with flammable gases or dust, therefore, lighting devices used in such environments must comply with strict explosion-proof standards.
- Mining: Coal mines or other mines containing combustible mineral dust also require the use of explosion-proof lamps to reduce the risk of explosion.
- Food processing industry: Some processing processes may produce flammable dust, such as mills or flour processing plants.
- Paint and coating facilities: These places may emit flammable vapors during production and storage processes.
- Pharmaceutical manufacturing: Some chemical synthesis processes may produce flammable substances.
- Military and aviation sectors: Explosion proof lighting is also required in areas such as ammunition depots and fuel warehouses to ensure operational safety.
- Shipbuilding industry: fuel tanks, paint rooms, and other spaces that may contain flammable gases or liquids.

In the above-mentioned industries, the use of explosion-proof lights is not only to ensure the safety of workers, but also to protect equipment and production facilities from damage. According to different environments and needs, explosion-proof lamps can also be classified into different levels and types, such as explosion-proof, increased safety, intrinsic safety, etc.
Explosion proof lighting equipment has a sturdy outer shell structure that can withstand internal explosions without damage, and does not allow internal explosions to affect the combustible environment outside. The increased safety type reduces the risk of igniting external flammable mixtures by limiting the temperature of electrical components and the current of the circuit. As for the intrinsic safety type, it is ensured through low-power design that it will not ignite surrounding flammable gases even under the most dangerous conditions.
