Protective Clothing Ensembles
This standard is issued under the fixed designation F2668; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Protective clothing ensembles such as firefighter turnout gear, HAZMAT suits, and bomb suits may
impose a physiological strain on the wearer. This strain can take the form of heat stress and
cardiovascular and respiratory strain, which can result in injury to the wearer. This practice provides
information on the measurement of the physiological responses of a wearer to a protective clothing
ensemble. The protocol is designed to allow comparisons of the physiological responses of subjects
wearingdifferentprotectiveclothingensemblesofthesametype(forexample,firefighterturnoutgear)
and from different types (for example, firefighter ensemble vs. HAZMAT suit).
