Chemical Protective Clothing, Category III
To facilitate the selection of Category III protective clothing the EU PPE Directive has broken Category III down into six levels of protection ( Types ) with each Type being associated with a deﬁ ned level of exposure . Type I represents the highest level of protection down to Type 6 which generally offers the lowest . The six exposure levels are designed to equate to different modes of exposure to increasingly serious threats and are a frequently referred-to when specifying protective coveralls.
When selecting or specifying a Category III garment it is often referred to by its CE Type certiﬁ cation. However this is not sufﬁ cient for an appropriate garment selection. Different protective garments that all meet the standards do not necessarily offer the same protection performance (please see Annexe 3). Different protective clothing products produced in compliance to a speciﬁ c CE Type can exhibit very different protection, durability and comfort performance characteristics. The CE Type designation simply implies that a suit has passed one or more of the deﬁ ned whole-suit tests and meets the minimum mechanical and barrier requirements.
