  • Protects against a wide range of chemicals
  • Extruded fabric construction for a smoother and more consistent fabric than bonded or glued processes
  • Supported by PermaSURE®  online tool to model permeation rates and provide safe-use times by calculating environmental, temperature and chemical exposure factors.

How long have I got?
The online PermaSURE® app is available for use with the ChemMax 3 chemical suit.

PermaSURE® is a free, mobile-friendly online tool that models permeation rates and provides safe-use times by incorporating environmental, temperature and chemical exposure factors. It is based on the known molecular characteristics and behaviour of 4000+ chemicals interacting with Lakeland’s specific chemical fabrics. Click the downloads tab for more info.

Lakeland coverall - strenuous work

Physical factors such as strenuous work?
The physical demands of a task such as climbing ladders, crawling or working in confined spaces, especially if the chemical is highly toxic,  may require higher strength fabric or a specific design, even though permeation analysis and/or the hazard spray type indicate a lighter/more comfortable garment.

Lakeland liquid or gas safety

Liquid or gas?
Liquid would normally suggest a Type 3 or 4 hazard. However, some chemicals have low boiling points, becoming vapour at low temperatures. In such cases a gas-tight suit might be appropriate. Such information can be obtained from Safety Data Sheets.

 

Type 3 vs Type 4 –  the different spray tests

EN 14605 – Type 3: ‘jet’ spraysEN14605 – Type 4: ‘liquid’ sprays

  • Strong, directional jets of liquid spray
  • Results in intense, local pressure on fabric, seams and joins
  • Back-spray will penetrate under, up or behind any loose flaps or joins
  • In finished garment spray test, single jets of liquid are sprayed at ‘potential’ weak areas of suit (seams, crotch, zip flap ect.)
  • Wider, less pressurised liquid sprays
  • Results in saturation of fabric (so sealed seams required) but no pressure on garment, seams or joins
  • No risk of back-spray penetrating under, up or behind loose flaps or joins
  • In finished garment spray test, four nozzles with general overspray of liquid

 

By identifying that your application is Type 4 only (rather than Type 3), this enables more options for garment design and choice, along with a greater level of comfort.

 

*About stitched and taped seams:

The seam is first stitched and sealed on the outside with a heat activated tape. This results in an impervious seam which is completely liquid-tight. As these seams are generally used for chemical suits the tape type is often constructed from a similar material to the garment fabric in order to maintain similar chemical permeation properties.

  • Grey coloured chemical coveralls
  • Multi-layer barrier film with smooth, flexible and even finish
  • Low noise level
  • Passes all four EN14126 bio-hazard tests
  • Cushioned double-layer knee pads
  • Super-B style: superior fit, wearability and durability
  • Three-piece hood, inset sleeves and diamond crotch gusset
  • Tapered centre piece, face and respirator mask fit
  • High neck and zip flaps
  • Double zip and storm flap front fastening
  • Suitable for asbestos handling and removal
  • Use PermaSURE® online tool with ChemMax 3
