SLIP

CHEMICAL

WHAT’S THE RISK? Chemical resistant footwear protects the wearer from chemical related hazards in the workplace. It’s important to understand the chemicals used in the environment and to use the appropriate classification of protective footwear to withstand chemical penetration and permeation according to the risk levels.

WHAT’S THE RISK? Safety footwear should protect the wearer from slip hazards in the workplace, ensuring that critical elements such as sole design and compounds are optimal for use to protect the wearer from such hazards.

This European Standard specifies a method of test for the slip resistance of conventionally soled safety, protective and occupational footwear. It is not applicable to special purpose footwear containing spikes, metal studs or similar. The item of footwear to be tested is put on a surface, subjected to a given normal force and moved horizontally relative to the surface. The frictional force is measured and the dynamic coefficient of friction is calculated. If the outsole passes both the ceramic tile test (SRA) and the steel floor test (SRB) it is marked as SRC.

WHO IS AT RISK? Those working in the chemical industry and in cleaning environments using harsh chemicals.

INJURIES This can cause skin sensitivity, irritation and chemical burns.

Footwear protecting against chemicals - Part 3: Requirements for prolonged contact with chemicals. Resistance to degradation: Samples are placed in contact with the chemical for 24 hours. This footwear resists permeation and degradation by the stated chemicals (at least 3 from the list below)
