Overview
The level 2 chemical protective suit RHF-II (semi-sealed type) is protective clothing worn by firefighters entering hazardous chemical or corrosive substance accident sites to carry out rescue operations. It is made from a modified PVC fabric coated on both sides, which resists acids and alkalis and also provides good flame retardancy and strength. The technical indices of the suit meet the requirements of XF 770-2008 Firefighter Chemical Protective Clothing. The suit is not limited to the fire service: it is also widely used in the petroleum, chemical and other industries.
Protective performance: acid and alkali resistance and flame retardancy. The suit can be used for rescue operations in organic media such as petrol, acetone and ethyl acetate, and in corrosive liquids such as sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid and sodium hydroxide.
