Pyrolon™ CRFR Cool Suit Suit with breathable back and elasticated hood, cuffs, waist and ankles

Style Number: ECRCF428

The Cool Suit® principle uses the main chemical protective coverall fabric for the garment and includes a breathable back covered by a flap sealed at top and sides. The innovative design allows circulation of air into the suit - enhanced by wearer movement - to radically improve comfort yet maintain protection against Type 4 liquid sprays.

  • Type 4 chemical protective coverall with elasticated hood, cuffs, waist and ankles with breathable rear panel
  • Pyrolon™ CRFR orange fabric with grey seams and rear panel cover for easy identification.
  • Pyrolon™ fabric with sealed seams provides both chemical protection and is FR to EN 14116- Index 1: the fabric will not burn or ignite, so unlike standard chemical suits Pyrolon™ CRFR can be worn OVER traditional thermal protective garments without compromising thermal protection.
  • Improved Super-B style coverall: superior fit, wearability and durability.

Features: Tape sealed seams, Breathable back panel, Double zip / storm flap front fastening, "Super B“ pattern

Physical properties data is based on standard tests required by CE certification designed to allow easy comparison of the strength, durability and robustness of different garments. Lakeland's "Guide to Type 5 & 6 Coveralls" contains easy reference comparison tables of Lakeland garments with main competitors. A glossary with brief explanation of these tests can be found in Lakeland’s “Guide to Chemical Suit Selection”.

Penetration is the process by which a liquid (or dust) will pass through the fabric via holes or gaps in its structure. It is generally measured using visual methods and is suitable for garments designed to protect against chemicals with lower levels of toxicity - those that require larger volumes to cause harm. (For combined chemical / FR protection against higher hazard chemicals see Pyrolon® CBFR)

For Pyrolon® CRFR & TPCR garments, because the resistance against permeation by chemicals is limited (see permeation test results) more extensive testing has been conducted according to the US ASTM F903 Penetration Test. This measures the time until a visible breakthrough of the chemical through the fabric is apparent. Pyrolon CRFR and TPCR combine chemical resistance with FR properties (certified to EN 14116 Index 1: unlike standard chemical suits the fabric will not ignite and burn* and so can be worn OVER Thermal Protective Garments WITHOUT compromising thermal protection. Whilst Pyrolon CRFR and TPCR have a limited permeation barrier, depending on the chemical toxicity, a penetration test result may be a good indication of suitable protection where the fire or flammability risk is of primary or major concern.
