Product Description

This item may be fitted by competent users, as defined in BS4275: 1974 (replaced by BS EN 529: 2005, presently under review) . 
It is tested compliant with the relevant provisions of EN 250 and EN 136, for robustness and duty. It does not include the visor and frame assembly.

Mask body, fitted with five buckles and demand, or breathing valve manifold to Interspiro Specifications. 

Scott/Kemira branded, othwerwise exactly similar to Interspiro's, the product and its tooling was was jointly developed with Kemira, in 1981.

It is made in grey rubber compound, mixed from SBR, natural and Neoprene rubbers and designed for general use in Diving SCUBA, industrial respirators and Firefighting BA.

Natural/Neoprene/Styrene Butadiene, mixed compound, is much stonger, more elastic and more comfortable than Silcone rubbers

Note that new, mask rubber components and new masks are coated with a thin layer of mould release wax, which also inhibits surface staining and oxidisation in storage. 
You may therfore see some residues, when unpacking. These may be wiped or washed off, prior to use, if desired. They are not harmful and contain no dermititic agents or solvents.
