1 Scope
This British Standard gives guidance on assessing the effects of personal protective
equipment (PPE) on heat stress and its consequences for possible heat-related health
problems (heat strain). This standard gives guidance on the application of the methods
for measuring heat stress given in BS EN 12515:1997 and BS EN 27243:1994 to workers wearing PPE.
NOTE 1 The conditions in which BS EN 12515:1997 and BS EN 27243:1994 are applicable (as outlined in the scope of each of these standards) are not extended
by this British Standard.
NOTE 2 Guidance on the application of the methods given in BS EN 12515:1997 and BS EN 27243:1994 to measurement of heat stress in workers wearing PPE is given in annex A and worked examples are given in annex B. Examples of the thermal insulation values of clothing are given in annex C. The theory behind the modifications to the method given in BS EN 12515:1997 for workers wearing PPE is given in annex D.
This British Standard is intended for use by all who:
a) have a responsibility for the health and safety of workers wearing PPE in situations
