Toxicity of the Off-Gas Products from Diver Hoses

Abstract

The Naval Civil Engineering Laboratory (NCEL) was requested to ascertain the compostion and toxicity of compounds off-gassing from diver hoses and to develop new acceptance tests for the military specifications for diver hoses. A literature survey disclosed that the off-gassing would consist primarily of organic solvents and would contain only traces of plasticizers and deterioration products of rubber. Two acceptance tests were developed for measuring the quantities of organic solvents emitted by diver hoses. In both tests, measurements of ionizable carbon are employed as indices of the concentrations of solvents vapors and related organic compounds. The concentration of nearly any compound that might off-gas from diver hoses should be at safe levels in breathing mixtures delivered through hoses that pass the above tests. Exceptions are that solvents carbon disulfide and carbon tetrachloride. Military specifications must forbid their use in the fabrication of diver hoses.
