A62D CHEMICAL MEANS FOR EXTINGUISHING FIRES OR FOR COMBATING OR PROTECTING AGAINST HARMFUL CHEMICAL AGENTS; CHEMICAL MATERIALS FOR USE IN BREATHING APPARATUS
Introduced: September 1968
Description
A62D covers chemical formulations and compositions for fire extinguishment and chemical hazard protection. This includes fire-suppressing agents and powders, chemical detoxification processes that neutralize or reduce the harmfulness of toxic substances, and material compositions for protective equipment such as chemical-resistant clothing, gas mask components, and respirator systems. The subclass encompasses both the active chemical ingredients and the material compositions used in personal protective equipment and breathing apparatus, excluding mechanical fire-fighting devices and the structural design of protective garments or masks themselves.
