Size Chart

The ChemDefend® 250 range of protective coveralls are constructed from a microporous polyethylene barrier film glued to the latest generation of spunbond polypropylene ( SBPP). The PP fibres are spun at a low dtex producing a high density of fine fibres per square metre, creating a lightweight and strong, but breathable material.The barrier and repellency to liquid chemicals and biological agents is excellent. This material is coated with an electrostatic dissipative layer.

ChemDefend® 250 range material is soft, quiet and drapable. The coverall is constructed to offer optimum body fit, with generous use of fabric in the underarms, chest and waist, allowing comfortable and unrestricted freedom of movement.

The garment incorporates a number of key design features to assist in maximising protection, comfort and strength and to ease the donning and doffing process.

The garment uses a sealed seam, bound with a barrier material to maximise the seam strength. This reduces any splitting or tearing in use and improves the liquid and particle barrier of the coverall.

Additionally, all the elastication within the coverall is fully bound and enclosed, and combined with the outer film layer delivers a coverall with reduced linting of any fibre contaminant.

EN1073-2:2002 – Protective clothing against radioactive particulate contamination.

EN1149-5:2008 – Protective clothing with electrostatic dissipative properties.

EN14126:2003 – Protective clothing against infective agents and biological hazards.

Type 5 – EN ISO 13982-1:2004+A1:2010 – Dry particle protection – suits which provide protection to the full body against airborne solid particles.

Type 6 – EN13034:2005+A1:2009 – Reduced spray-suits which offer limited protection against a light spray of liquid chemicals.

The product range is available in sizes Small to 3XL and a range of styles to suit different applications.

Note: ChemDefend® does not give any warranties or make any representations about its coveralls other than those contained within the official literature supplied by ChemDefend® with each coverall. Risk analysis should be carried out by the user to select the appropriate PPE and it is the user's responsibility to select the correct combination of full body protective coverall and other equipment. The user will also need to determine how long a coverall can be worn for a particular use and/or exposure to a hazard, with regard it its protective performance, comfort and heat stress. Unless otherwise stated all test data relates to laboratory test data generated on fabrics only. Note that seams and closure systems may offer different, possibly lower chemical barrier protection.
