Heavy-duty Chemical Protective Suit
Chemical protective class one ensemble for firefighters is specially designed for fighters to protect them-self from being damaged by chemical substances when in fire spot or in accident spot.
RHF-02 suits will not getting flux and dropping only carbonization. Sewing to the use of frame-resistant and adhesive strong the Nylon, with both-sides being covering with chemical protective and fire-resistant rubber. Both-surface chemical resistant rubberized fabrics, then process it into the clothing and gloves in glue of laminating then combine with a chemical protective and fire-resistant and spike-resistant of boot to make up a set of clothing.
