| Abstract |
In Japan, there are two safety codes for gas-removing respirators and gas mask canisters: Japan Industrial Standard (JIS) T8152 and the safety code of the Ministry of Labour (MoL). The MoL code was established later than the JIS code, as a simplified standard comparable to foreign ones. The MoL code reduced the number of test materials, deleted numerical criteria for structural criteria such as field of view, and simplified test conditions for air-flow resistance. Current topics under study are the distribution of service lives of canisters and cartridges from one lot of articles, and the usefulness of changes in weight of canisters or cartridges for estimating breakthrough times. New respirators for protection against toxic gases used in semiconductor manufacture are needed, as are sensors for breakthrough detection. |
