OPCH-05 special protective clothing system
Special ventilation insulating chemical protective clothing
Technical specifications
The OPCH-05 ventilation chemical insulating suit was developed in cooperation with the companies ECOPROTECT, s.r.o. and MALINA SAFETY, s.r.o. based on requirements of the Czech Army to replace the existing OPCH-90. The suit is designed for use in conjunction with a mask (OM-90).
OPCH-05 is a special protective device of the insulating type intended for multiple use serving to provide skin protection from toxic liquids or vapours, biological warfare agents and radioactive dust.
In conjunction with special filters, a self-contained breathing apparatus or an external air source, the OPCH-05 can also be used during industrial accidents involving release of toxic substances.
The outfit consists of 2 main parts, viz. the clothing and a filtering-venting unit. The OPCH-05 can also be used without the filtering-venting unit (unventilation variant).
The clothing system consists of the following components:
- Overall with overshoes and a hood with a sealing face flange
- Rubber gloves
- Special underwear (two-part)
- Air manifold with tubes
- Diaper underpants
- Cooling garment
The overall, underwear, inner gloves, overshoes, rubber gloves, and cooling garment are available in 3 sizes.
