Choose the Right Light Source: LED lighting is a popular choice for hazardous environments due to its energy efficiency and low heat output. However, not all LED lights are suitable for hazardous environments. Look for lights that have been specifically designed for use in hazardous locations and have been certified by organizations such as Underwriters Laboratories (UL) and the Canadian Standards Association (CSA).
Understand Hazardous Area Classifications: The NEC and IEC provide guidelines for hazardous area classifications, which are based on the type and quantity of hazardous materials present. The classifications are divided into zones or divisions, which indicate the level of hazard. For example, a Class I, Division 2 environment is a location where flammable gases or vapors may be present in the air, but not in sufficient quantities to cause an explosion.
Follow Installation Guidelines: Installation guidelines for EX-Proof Lighting must be followed carefully to ensure that the lighting system is installed safely and correctly. The installation process may involve wiring, grounding, and mounting the lighting fixtures. It is important to follow the manufacturer’s installation instructions and any applicable regulations or standards, such as the NEC or IEC. For example, when installing lighting in a Class I, Division 2 environment, the wiring must be sealed to prevent the escape of flammable gases or vapors.manufacturer’s installation instructions and any applicable regulations or standards, such as the NEC or IEC. For example, when installing lighting
Perform Regular Maintenance: Regular maintenance is essential for ensuring that lighting systems continue to operate safely and efficiently. Maintenance tasks may include cleaning the fixtures, replacing bulbs or other components, and checking the wiring and grounding. Regular maintenance can help prevent equipment failure and reduce the risk of accidents. For example, the Appleton Mercmaster LED Luminaire features a modular design that allows for easy maintenance and replacement of components.
Consider Lighting Controls: Lighting controls, such as dimming and occupancy sensors, can help reduce energy consumption and improve worker comfort and productivity. However, not all lighting controls are suitable for hazardous environments. Look for controls that have been specifically designed for use in hazardous locations and have been certified by organizations such as UL and CSA.
Ensure Adequate Illumination: Adequate illumination is essential for worker safety and productivity. Lighting levels should be sufficient for the task at hand and should be evenly distributed throughout the work area. It is also important to consider the CRI of the lighting system, which indicates how accurately colors are rendered under the light.
Plan for Emergencies: In the event of a power outage or other emergency, it is important to have a backup lighting system in place. Emergency lighting systems should be designed to provide adequate illumination for evacuation and emergency response. For example, the Lithonia Lighting EXG LED Emergency Exit Sign features a battery backup system that provides up to 90 minutes of illumination in the event of a power outage.
By following these technical tips and selecting lighting solutions that are certified for use in hazardous environments, operators can ensure that their lighting systems are safe, reliable, and compliant with regulations and standards.
