Hazardous Area Lighting

What is hazardous lighting

In a typical lighting fixture, the contacts, bulb, wiring and switches are exposed to the atmosphere. The spark from a movement of the switch, and even the heat of the bulb can be enough to create a flammable atmosphere. In a flammable proof lighting fixture, any explosion that may happen is contained inside of the fixture itself. Most people presume that these installations work by having a seal around the bulb as well as any switches so as to not allow flammable specks to become exposed to a spark or heat. This isn’t correct. More correctly, the fixture lets a small amount of air to flow within the fixture, and should be combustible pieces ignite, the fixture is designed in such a way that it will contain the flame inside the fixture housing.

Explosion proof lighting is a light fixture capable of withstanding an explosion in areas that are hazardous, such as manufacturing plants or laboratories, without the fixture breaking, shattering, or being otherwise compromised. Certain fixtures of this nature are also able to contain the explosion from even spreading into the environment surrounding the fixture. This type of lighting is ideal for areas where vapors, gases, heat, or other flammable materials are present to help reduce the likelihood of a total loss of your light fixtures in the event of an accident, and they also ensure glass from the fixture won't go flying in the event of an explosion which only adds to the danger of the situation.

What are Hazardous locations

Hazardous locations are defined as any area where there are high concentrations of combustible particles in the air that may cause an explosion or fire. These flammable materials include, but are not limited to, liquids, dust, gasses and some fibres. Whenever these hazards are present, employees must use specially designed equipment to avoid the chance of igniting any of these materials. According to OSHA (Occupational Safety and Health Administration), Hazardous locations are those areas “where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings.” Hazardous locations or areas are usually classified by specialists in the field, such as electrical inspectors, engineers, owners, area experts, and insurance companies. They may divide extreme locations into either ordinary (shocks & fires) or hazardous (explosion prone) areas.

The kind of lights required in a hazardous area is fixed on by the kind of flammable materials that will be in the air where the fixtures are going to be used.

How to identify quality explosion proof lighting

Identifying quality explosion-proof lighting is essential to ensure safety and reliability in hazardous environments. Here are some key factors to consider when evaluating the quality of explosion-proof lighting:

1. Certifications and Compliance: Look for explosion proof lighting fixtures that have obtained relevant certifications, such as ATEX, IECEx, UL, or CSA, depending on your region's regulations. These certifications ensure that the fixtures meet strict safety standards and have undergone rigorous testing for use in hazardous areas. We Duallitec Electric Singapore supports only reputable explosion proof lighting brands from the USA and Europe. 

2. Construction and Materials: Quality explosion-proof lighting fixtures are constructed using durable and robust materials that can withstand harsh conditions. Look for fixtures made from corrosion-resistant metals, such as aluminum or stainless steel, as well as impact-resistant and heat-resistant components. The use of tempered glass or polycarbonate lenses on such explosion proof lighting adds an extra layer of protection.

3. Sealing and Enclosures: Pay attention to the sealing and enclosure design of the explosion proof lighting fixtures. They should have a robust sealing mechanism to prevent the entry of hazardous substances and to maintain the integrity of the explosion proof lighting system. Look for features like gaskets, O-rings, and threaded enclosures that ensure a tight and secure seal.

4. Wiring and Connections: Check the wiring and connections of the explosion-proof lighting fixtures. High-quality fixtures will have explosion-proof wiring methods, such as threaded conduit entries or explosion-proof connectors, to prevent sparks and ensure proper electrical connections.

5. Temperature Ratings: Consider the temperature ratings of the lighting fixtures. Explosion-proof lighting should be designed to operate safely within the specified temperature range of the hazardous environment. We Duallite Electric Singapore will be able to assist to propose the suitable explosion proof lighting for all singapore and south east asia hazardous environments.

6. Manufacturer's Reputation and Expertise: Research the manufacturer's reputation and expertise in producing explosion-proof lighting. Choose manufacturers with a track record of providing high-quality and reliable lighting solutions for hazardous environments. Read reviews, seek recommendations, and consider their experience in the industry. Duallite Electric Singapore is in the business for more than 20 years, our team have the experience and reliability to tackle most projects in Singapore, Indonesia and Malaysia. 

7. Warranty and Support: Check the warranty and support offered by the manufacturer. A reputable manufacturer will stand behind their products and provide a warranty that covers defects and failures. Additionally, they should offer technical support and assistance in case of any issues or questions regarding the lighting fixtures.

By Considering these factors, you can identify high-quality explosion-proof lighting that meets safety standards and ensures reliable performance in hazardous environments. Consulting with experts in the field or seeking professional advice can also help in making informed decisions regarding the selection of quality explosion-proof lighting.
