This document defines the general requirements for ventilation equipment used to capture and separate fumes generated by welding and allied processes, e.g. arc welding and thermal cutting. This document also specifies the test data to be marked on the capture devices. It applies to the design and manufacture of parts of the equipment including hoods for welding, ducting, filter units, air movers, systems that inform of unsafe operation and workplace practices to ensure safe working with regard to exposure. Significant hazards are listed in Clause 4. It does not cover electrical, mechanical and pneumatic hazards. This document is applicable to: — local exhaust ventilation systems (LEV) excluding draught tables; — mobile and stationary equipment; — separation equipment used for welding and allied processes; This document is not applicable to: — general ventilation, air make up or air movement systems; — air conditioning systems; — grinding dust. This document applies to systems designed and manufactured after its publication. NOTE Specific safety requirements for thermal cutting machines are defined in ISO 17916.
