UL 1345 applies to lighting fixtures that are designed for use in explosive gas atmospheres or combustible dust environments. It covers general-purpose lighting fixtures as well as special-purpose fixtures such as emergency lighting, exit signs, and floodlights. The standard specifies requirements for construction, wiring, electrical ratings, marking, and performance characteristics of these fixtures. It also provides guidance on documentation, testing, and certification processes for manufacturers.

Testing Requirements for UL 1345 Certification

To obtain UL 1345 certification, lighting fixtures must undergo rigorous testing by an independent laboratory accredited by the Occupational Safety and Health Administration (OSHA) and the Standards Council of Canada (SCC). The testing process includes various tests to evaluate the durability, flame resistance, temperature limitations, corrosion resistance, and electrical safety of the lighting fixtures. Any lighting fixture that successfully meets all the testing requirements will be granted UL 1345 certification.

The Benefits of Using UL 1345 Certified Lighting Fixtures

The use of UL 1345 certified lighting fixtures in hazardous environments offers several advantages. Firstly, it ensures the safety of individuals working in these environments by minimizing the risk of accidents and explosions caused by faulty lighting fixtures. Secondly, UL 1345 certification provides assurance that the lighting fixtures conform to recognized safety standards and undergo regular testing to maintain their safety performance. Thirdly, using UL 1345 certified lighting fixtures can help organizations comply with regulatory requirements and avoid potential legal liabilities.
