SELECTION OF EQUIPMENT
This device should only be used in the following circumstances:
•
Factors/circumstances constituting respiratory hazard cannot be eliminated by other means.
•
A suitable and sufÞ cient risk assessment has been carried out which identiÞ es the hazards present
and the level of risk.
The risk assessment should identify:
•
The hazardous substances/chemicals present in the atmosphere, their physical state (liquid,
vapour, solid, gas), and likely levels of contamination.
•
Other hazards in the workplace, e.g. ß ying or falling solid objects, liquid splashes, molten, metal
splashes, potentially explosive atmospheres, noisy environments, UV, IR radiation etc.
•
Wearer factors such as medical Þ tness, beards or spectacles
•
Job/task factors such as required mobility, workrate, tools to be used, other PPE to be used (e.g.
protective clothing).
•
Environmental factors such as temperature, humidity or high winds.

Therefore, devices of class TH1 must never be
20
used against carcinogenic, very poisonous or
100
radioactive gases and vapours.
For devices with combined Þ lter apply the
relevant limitations of gas and particle Þ lters.
