Local Exhaust Ventilation (LEV)


The HSE law says if you have Local Exhaust Ventilation installed it must ‘have a periodic thorough examination and test.’

Local Exhaust Ventilation (COSHH LEV)

Smoke Test

Some systems require inspections done at smaller intervals, such as processes,  in which metal articles (other than gold, platinum or iridium) are ground, abraded or polished or Processes giving off dust or fume in which non-ferrous metal castings are produced which both require 6 monthly inspections.
