Explosion proof lamp

Explosion-proof lights are used in places where there is a possibility of explosion or fire. Explosion-proof lights are made in such a way that no spark occurs between them when the contacts are connected. An explosion-proof light is usually made of a very resistant lens or glass and is inside a thick steel frame. or aluminum is placed.

By using explosion-proof lights, in case of a spark inside the lamp housing, no burnt compresses will get out of the housing, and explosions and fires in the environment will be prevented.

How is an explosion-proof lamp made?

The manufacture of explosion-proof lights is completely different from ordinary lights, and these lights must have the most reliable explosion-proof certificates and standards. Before starting to operate and in order to obtain valid certificates, these lights must be tested. tests and various tests to provide correct use.

Tests such as:

• Testing the degree of protection against dust and moisture
• Durability test against cold and heat
• THERMAL TEST
• Dielectric test
• Impact and height test

The explosion-proof lamp is made of a highly resistant lens or glass that is placed inside a thick steel or aluminum housing. For this reason, these lights can be used in high-risk environments and harsh conditions, and by preventing cracking, they can prevent explosions in places prone to fire or explosion.

In environments that are prone to explosion due to the presence of flammable gases and vapors, lamps, contacts, wiring and any other switches are directly exposed to the ambient atmosphere. In such environments, sparks result from a contact or movement of the switch. And even the heat of the lamp can cause explosion and fire.

The explosion-proof lamp is usually made of a lens or glass with very high resistance, which is placed inside a thick steel or aluminum housing.

Explosion-proof lights and lighting equipment are designed and manufactured in such a way that any connection or spark occurs only inside the main compartment and its transfer to the outside and unsafe environment is prevented. Also, flammable gases and vapors penetrate into the compartment. The light is blocked.

Types of explosion-proof lights

Explosion proof lights by model

• Explosion-proof wall light: These lights are installed on the wall. Tunnel lights can also be included in this category.
• Hanging explosion-proof lights: This type of explosion-proof lights can be used in mines, oil refineries, petrochemical industries, fuel stations and anywhere that is prone to explosion.
• Anti-explosion fluorescent lamp: This type of anti-explosion lamp is used in environments such as refineries where there is a risk of ignition due to gas leakage.
• Hand-held explosion-proof lamp (portable explosion-proof lamp): This example of explosion-proof lamps is designed for use in environments such as mines.
• Anti-explosion street lights: this type of lights has a strong and resistant body against various weather factors and is suitable for use in various oil, gas and petrochemical industries where there is a possibility of combustion.
• Anti-explosion lamp for tank inspection: Anti-explosion lights for tank inspection (Tank Inspection Vessel Lamps) for providing the necessary lighting for inspection and observation inside tankers in industrial environments such as oil platforms, oil and gas industries, petrochemical, fuel stations and all industries. which have fuel tanks are used. This type of explosion-proof lights are suitable for use in Zone 1, 2, 21, 22 areas.
• Explosion Proof Emergency Exit Light: Explosion Proof Emergency Exit Light is a type of warning light that lights up in times of danger and shows the way out. Given that these lights must be used in dangerous situations and To be used in case of fire, it is necessary to have a very high resistance against explosion and fire.

Explosion-proof lights are classified in two areas:

• In the zone 1 prone to explosion
• In the zone 2 prone to explosion

Types of lamps used in explosion-proof lights

• Anti-explosion lamp with sodium vapor lamp: these lamps are suitable for lighting passages and places where there is not much traffic. (yellow color)
• Explosion-proof lights with mercury vapor lamps: Explosion-proof lights with mercury vapor lamps are used in passages. (yellow color)
• Explosion-proof lamp with metal halide lamp: the color of this lamp is very whitish (natural and attractive) and all objects under this light are in their natural color (white color).

Features of explosion-proof lights

• High resistance: the costs related to the maintenance, replacement and repair of lighting devices used in the workplace will be significantly reduced due to the high resistance and durability of explosion-proof lights.
• Less heat generation: explosion-proof lights emit less heat due to economy. This greatly reduces the possibility of sparks.
• Portability: Explosion-proof lights are portable due to their glass frame and protection against vibration and physical shocks.
• High efficiency: using explosion-proof lights will reduce production and operating costs.

Where are explosion-proof lights used?

Explosion-proof lights and lighting tools are used in dangerous places that are prone to explosions and fires (places where there are potentially explosive gases and vapors).

• Refineries
• Fuel supply station
• Oil and gas tanks
• Drilling platforms and oil terminals
• Petrochemicals
• Stone mines

Employees of jobs that operate in dangerous and explosive environments are constantly exposed to the risk of possible explosions and fires. This is why in many countries, the existence and use of anti-explosion equipment in dangerous jobs (refinery, Oil and gas tanks, etc.) are necessary and mandatory.

Explosion-proof lamp standards

Before buying any explosion-proof equipment, including explosion-proof lights, special attention should be paid to its certification and its standard. Any explosion-proof lights and lighting devices that do not have a certificate and standard will not have any value. This is because no test by Valid bodies have not been done on them.

ATEX explosion proof lights standard

he ATEX explosion-proof equipment standard stands for the French word Atmosphere Explosive and is considered one of the most important safety and protection guidelines in the European continent.

Explosion-proof lights and other explosion-proof equipment must pass the following tests to receive ATEX certification:

• Testing the degree of protection against dust and moisture
• Durability test against cold and heat
• THERMAL TEST
• Dielectric test
• Impact and height test

Explosion proof lamp coding

(EX d IIC T3) These terms and numbers are an example of the coding of explosion-proof lights and are read in the following order.

(EX) stands for EXPLOSION PROOF and means anti-explosion.
(d) This word means explosion-proof enclosure. All electrical equipment of explosion-proof lights are located in this compartment.
The term (IIC) indicates that this lamp is operational in the presence of IIC group gases.
The expression (T3) indicates that the level of this lamp will not be higher than 200 degrees under any circumstances. Therefore, the explosion-proof lamp is suitable for use in the presence of gases with an auto-ignition point of 200 degrees and above.

IEC standard for explosion-proof lamps

IEC is one of the affiliated organizations of the ISO International Organization, which is responsible for compiling the standards required by the electricity industry.

In this standard, hazardous environments are divided into three zones or zones according to the amount of hazardous gases.

In the IEC explosion-proof equipment and light standard, the codes on the equipment are divided into four parts:

EX: Mark and symbol of explosion-proof equipment in IEC standard
Protecyion Types System protection type: This section includes i, d, p, e and... subgroups
Gas group: into two parts of the gas group and gas group || It is divided. Gas group || It has subgroups A, B, C.
Thermal class T: from 85 to 450 degrees Celsius.

Before buying an explosion-proof lamp, special attention should be paid to the existing standards and certificates.

It is necessary to use explosion-proof equipment in high-risk environments. The explosion-proof lamp is one of the most widely used explosion-proof equipment used in these environments.
