The regulations for LEV testing are set out by the Health and Safety Executive (HSE) in the Control of Substances Hazardous to Health (COSHH) guidelines. It's mandatory that every employer should maintain working conditions for the employees, and any employer who uses LEV techniques in the workplace must have the equipment examined and tested every 14 months to ensure it's working effectively and safely. Our engineers hold the BOHS P601 certification, which is one measure of competency in this area and we pay close attention to the HSE guidelines while undertaking any examination, maintenance, or repair work.
