Footwear standards for static dissipative footwear
International Standards recommend regular testing of static dissipative footwear. The Sole-Mate™ provides a time-efficient and cost-effective method of ensuring personnel operating in hazardous areas are wearing static dissipative shoes that are capable of mitigating electrostatic charge accumulation on their bodies.
Both IEC TS 60079-32-1 Section 11.3 Dissipative and conductive footwear, and NFPA 77 Section 8.2.2.2 Static Dissipative (SD) Footwear/ESD Shoe Tester refer to 1 meg-ohm up to 100 meg-ohm (1 x 106 Ω up to 1 x 108 Ω) resistance through the shoes.
EN ISO 20345, which is another safety footwear standard, specifies a resistance range of 100 kilo-ohm up to 1000 meg-ohm (1 x 105 Ω up to 1 x 109 Ω).
When specifying footwear testers it is important to know what specification the shoes are manufactured to so that the applicable resistance range is tested on entry to the HAZLOC/EX area.
For example, if shoes manufactured in accordance with EN ISO 20345 are tested on a footwear tester designed to test shoes at IEC TS 60079-32-1 and NFPA 77 levels, there is a strong possibility that the tester will fail the shoes.
Footwear resistance testing
Footwear testers need to be used in accordance with the manufacturer’s instructions, and installed indoors in a safe area, for testing before entering the hazardous zone.
They are not designed to ensure 100% compliance with the relevant footwear standards. They can only indicate if the resistance through the shoes is below the maximum permitted resistance outlined in the relevant standard/s.
It is the site operator’s responsibility to ensure adequate levels of training are in place to ensure people use such testers correctly and Standard Operating Procedures (SOPs) are in place so that shoes not in the specified range do not get used in the zoned or classified area.
The Sole-Mate™ tests the resistance of static dissipative footwear to verify the resistance between the operator and the flooring meets specified safety standards/guidance like EN ISO 20345, IEC TS 60079-32-1, NFPA 77.
Easy to use
Designed for indoor installation in non-hazardous areas, the Sole-Mate™ is a user-friendly device designed to test the condition of static dissipative footwear before entering safety-critical hazardous areas exposed to potentially ignitable atmospheres. It provides a clear PASS or FAIL visual indication, offering a quick and easy verification of footwear compliance.
