Strong jet sprays –
higher pressure
Surrounding gases or vapours

 

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’ sprays EN14605 – 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.
