A 62 D

 CHEMICAL MEANS FOR EXTINGUISHING FIRES OR FOR COMBATING OR PROTECTING AGAINST HARMFUL CHEMICAL AGENTS; CHEMICAL MATERIALS FOR USE IN BREATHING APPARATUS
 

Note
 

Processes using enzymes or micro-organisms in order to:
 

(i)

 liberate, separate or purify a pre-existing compound or composition, or to
 

(ii)

 treat textiles or clean solid surfaces of materials
