This standard specifies performance requirements for chemical protective suits with liquid-tight connections between different parts of the clothing for use by emergency teams, e.g. fire brigades, in situations where the chemical hazards are not immediately identifiable.
This standard specifies performance requirements for both the materials of construction of the chemical protective suit and for the suit as a whole, including component parts, seams, joins and assemblages.
This standard is applicable to reusable and limited-use chemical protective suits.
Chemical protective clothing conforming to this standard is not designed to provide protection against gases and vapours. Performance requirements for gas-tight chemical protective suits for emergency teams are given in BS EN 943-2.
NOTE Suits conforming to this standard can be suitable for use in situations other than those involving purely chemicals, e.g. situations involving infective agents and radioactive contamination. Information supplied by suit manufacturers can indicate such additional performance applications.
The chemical protection suits specified in this standard are designed to be used with respiratory protective devices. However, this standard does not specify requirements for respiratory protective devices.
