5 Safety requirements and/or measures
5.1 Preseparator
The welding fume separation equipment or the exhaust system shall be designed to protect the separation unit and
shall prevent damage to the filter caused by the impact of large, hot and/or abrasive particles.
5.2 Emission of particles from welding fume separation equipment
5.2.1 Welding fume separation efficiency
Welding fume separation equipment shall have a separation efficiency of at least 95 % and shall be assigned to a
welding fume separation class using the classification system given in Table 2. The welding fume classes differ in
the requirements for the separation efficiency based on the state of the art.
Table 2 — Welding fume classes
Welding fume class Separation efficiency (%) Recommended for the separation of particles generated by
welding of:
W 1 unalloyed and low-alloy steel, i.e. steel with a very low nickel
≥ 95
and chromium content
W 2 as above and alloyed steel, i.e. steel with a nickel and
≥ 98
chromium content ≤ 30 %
W 3 as above and high-alloy steel
≥ 99
NOTE The welding fume classes are only intended to provide guidance on the suitability of a given unit when considered in
combination with:
the welding location (e.g., a confined space or open workshop);
the fume emission rate;
the toxic elements present in the fume;
current legal requirements; and
the capture efficiency.
5.2.2 Marking of welding fume separation equipment
The manufacturer shall mark the welding fume separation equipment to indicate the welding fume class to which it
has been assigned using labels conforming to the specifications given in Annex A. The marking s
