Overview
The level 1 chemical protective suit RHF-I (fully encapsulated type) is designed and manufactured to XF 770-2008 Firefighter Chemical Protective Clothing. The fabric is a PVC double-coated textile produced by laminating several material layers together.
The suit consists of a large-view face window, a breathing apparatus backpack, puncture-resistant chemical boots, chemical gloves, a sealed zip and a ventilation system. It must be used together with a self-contained breathing apparatus. Under positive pressure the suit effectively prevents the ingress of toxic, harmful and corrosive gases and liquids, protecting the wearer in hazardous environments. It is intended for firefighters working at acid and alkali chemical accident sites.
