The Lakeland ChemMax 3 Type 3/4 chemical suit is made from a superior multi-layer barrier film laminated to a spunbound PP substrate.
- Soft and flexible multi-layer barrier fabric for protection against a wide range of chemicals
- This grey coloured chemical suit features extruded fabric construction which results in smoother and more consistent fabric than bonded or glued processes
- Superior softness, flexibility and more consistent chemical barrier (no ‘pinching’ or thinner bond points)
- European manufactured fabric, tested against a full range of chemical warfare agents for anti-terror and civil defence operations
- This coverall also offers Type 5/6 protection
- Extremely low noise level for improved safety and comfort
- All Lakeland ChemMax chemical coveralls feature cushioned double-layer knee pads for increased comfort and safety
- Super-B style design – this coverall has been developed for a superior fit, wearability and durability
- This well-fitted garment features inset sleeves and diamond crotch gusset
- These chemical coveralls feature a three-piece hood design with a tapered centrepiece for a superior face and respirator mask fit
- Advanced face and neck protection with higher neck and zip flaps
- Double zip and storm flap – front fastening for safe and secure protection
- All ChemMax protective coveralls feature stitched and taped seams to create fully sealed seams against liquid and dust ingress*
- Permeation tested against a basic range of chemicals
- Other chemical protective coveralls also available include the mid-level ChemMax 2 and the entry-level ChemMax 1
- All Lakeland coveralls are suitable for asbestos handling and removal
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.
Which garment to use:
Gas or Vapour
|Light spray/aerosol protection||Dry particle protection||General overall spray:|
no pressure but coverall soaked
|Strong jet sprays –|
|Surrounding gases or vapours|
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|
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.
