Which garment to use:

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.

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.
