Chemical repellent flame retardant disposable coverall – Lakeland Pyrolon CRFR

Lakeland’s Pyrolon chemical repellent and flame retardant suit is a highly flexible disposable coverall, delivering Type 3/4 chemical protection.

• Lakeland’s Pyrolon CRFR are both chemical repellent and flame retardant.
• These coveralls meet the requirements of EN 14116 (Index 1: Materials do not propagate a flame / no flaming debris / no spreading afterglow) for garment protection against heat and flames.
• Thermal Mannequin Tested – when the Pyrolon CRFR is worn over a Thermal Protective Garment (TPG) a total predicted body burn is as low as 24% of 1st degree burns.
• The fabric on chemical flame retardant suit will not ignite and chars at a low temperature, and unlike other disposables, these flame retardant coveralls will not continue to burn after the ignition source is withdrawn.
• It can be used safely over thermal protective garments without compromising protection.
• Offers Type 3/4 chemical protection against low to high pressure liquid sprays. Additionally offers Type 5/6 protection
• These coveralls feature stitched and taped seams to create fully sealed seams against liquid and dust ingress*
• Features outer FR PVC barrier film to proprietary nonwoven substrate of viscose rayon.
• Pyrolon flame retardant suit features super-B style design – this coverall has been developed for a superior fit, wearability and durability
• All Lakeland coveralls are suitable for asbestos handling and removing

Typical applications include:

• Petrochemical and refining industries
• Wear over thermal protective garments without compromising chemical protection
• Maintenance applications
• Fuel handling and distribution
• Oil spill clean ups

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.
