Hazmax™ Chemical Protective Safety Boots
For hazardous or aggressive chemicals our Hazmax™ range of boots offer unrivalled chemical protection. Hazmax™ safety boots are widely used by emergency responders and people working with or transporting aggressive or other hazardous chemicals.
Hazmax™ boots and overboots are certified to EN13832-3, the European standard for chemical protective footwear and meet the requirements of NFPA 1991 for chemical vapour protection.
Applications
Workmaster Hazmax™ safety boots are suitable for a number of industrial, chemical, pharmaceutical and emergency situations. Hazmax™ boots are available in an Electro-Static Discharge (ESD) variant, suitable for applications such as pharmaceutical electro-protective areas. Hazmax™ FPA boots are also available which offer the same performance of Hazmax™ boots but provide increased heat resistance and conform to the EN 15090:2012 F3A Fire fighter boot standard.
Hazmax™ compact chemical protective overboots are designed to fit simply of traditional safety shoes and trainers. Hazmax™ Maxi chemical overboots are designed to be worn over safety boots.

The Hazmax™ Range of Chemical Protective Boots
Hazmax™ Boots Chemical Permeation
The resistance of a boot compound to permeation by hazardous liquid and gaseous chemicals is defined by the permeation rate of the chemical through the compound and the breakthrough time. Permeation test methods include ASTM F739, EN374-3 and ISO 6529; exposure of the material to the chemical is total and constant, and emulates total immersion conditions.
The outer surface of the material is exposed to the test chemical. The inner surface of the material is monitored analytically to determine the amount of chemical (if any) permeating the material. The normalised breakthrough time (according to EN374-3:2003) is the elapsed time measured from the start of the test to the time at which the test chemical reaches a permeation rate of 1.0ug/(min.cm2).
The list below shows the 15 standard chemicals defined in EN943-2:2002 and their defined breakthrough time against our class leading Hazmax™ compound. For the full list of chemical permeation data, please click the button below.

With an in-house UKAS accredited materials testings laboratory we are able to perform a range of chemical permeation and physical testing to European, American and international standards. This also allows us to regularly re-test our materials to ensure quality.
Product Care
Please ensure that all strong chemicals or other types of contamination are washed off as soon as possible. Serious damage may result if certain chemicals, fats & oils are not removed, or if the boots are not cleaned regularly after use. If the Hazmax™ boot is cut or damaged then it will no continue to give the specified level of protection. Damaged boots should be immediately replaced.
The boot lining should be wiped with a mild detergent from time to time. Do not expose the boots to temperatures about 60°c when drying.
