Local Exhaust Ventilation (LEV) Testing
Local exhaust ventilation systems (LEV) are an engineering control system used to extract air which contains harmful contaminants away from the worker to prevent potential harm.
Examples of LEV’s include paint spray booths, welding fume hoods and fume cupboards. The law states that these systems must be tested and checked by a competent person every 12-14 months. Testing includes a combination of physical checks, observations and also air flow and pressure measurements taken throughout the system.
