2. Roll outer legs up approximately 20-23cms (Fig.7)
3. Step into protective boots (Fig.8)
4. Roll down outer leg over exterior of boots (Fig.9)
Exactly the same procedure should be utilised when wearing suits with elasticated inner and outer legs, plain inner and outer legs
and plain socks with elasticated outer legs or plain outer legs.
Single elasticated legs

3. Close the outer zip flaps securely with the velcro (Fig.16)
Doffing procedure
It is recommended that the doffing procedure is carried out with the aid of a dressing assistant. Depending upon the contaminant
encountered, it may be necessary for the assistant to wear appropriate PPE selected by qualified safety personnel. Remove all
sealing tape from around the face mask, arms and ankles.
1. Open the zip flaps by unfastening the velcro closures, then unfasten the zipper
2. Fold the hood of the coverall up and over the wearers head

Chemical permeation testing at Respirex
Permeation is the process by which a chemical moves through protective clothing material on a molecular level. At its headquarters
in Surrey, UK, Respirex operate a chemical permeation testing laboratory equipped with the latest technology. All testing is carried
out by fully qualified chemists who are able to test Respirex's own materials against a wide range of chemical substances. In
this way the customer can be advised and recommended the most suitable material to use against any challenging chemical
encountered in the workplace.
Permeation tests can be carried out in accordance with EN374-3, EN ISO 6529 and ASTM 739. The clothing material is exposed to
the challenging chemical in a permeation cell so that breakthrough times and permeation rates can be measured. Breakthrough
time is the time taken for the chemical to permeate through the material after continuous contact with the outer surface of a
chemical safety suit. Permeation rates, measured in µg (min.cm²), are an indication of the amount of chemical reaching the wearer
inside the suit after breakthrough occurs.
