ChemMax™ 1 overboots with anti-slip soles

Style Number: CT1S023NS
  • Very lightweight, soft and flexible fabric.
  • Low noise level - improved comfort and safety.
  • Anit-slip sole is backed by ChemMax™ 1 fabric so chemical barrier is maintained on the sole.
  • Very cost effective Type 3 & 4 Partial Body chemical protection.
  • Infectious Agent Barrier - passes at highest classes in all four EN 14126 bio-hazard tests (EB version used extensively by UK Government health workers in 2015 West African Ebola Crisis).
  • 31cm Overboots with textured PVC anti-slip soles a calf and foot ties

Features: Tape sealed seams, Over-boots

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 Chemical Suit Selection" contains easy reference comparison tables of Lakeland garments with main competitors along with a glossary with brief explanation of the tests.

NOTE: Permeation test data relates to "Normalised Breakthrough" which measures the time for the permeation rate to reach a specific speed (In CE EN 6529 testing, 1.0µg/min/cm2 and in US ASTM F739 testing, 0.1µg/min/cm2). This does not indicate when the chemical first breaks through the fabric and is not an indication of how long the suit can be safely used as the chemical may have permeated through the fabric before the Normalised Breakthrough time. This might be critical in cases of chemicals with high toxicity.
