| Abstract |
A welder's helmet was modified by adding a millipore filter holder, a tube for the sampling of carbon monoxide, and a Teflon tube for the sampling of nitrogen dioxide and ozone. The helmet is also equipped with a compressed-air plenum chamber for conducting tests with or without supplied air. The sampling tubes are connected to conventional midget impingers and bubbers modified in order to prevent loss of liquid in certain welding positions. The apparatus, which can be made in any glass-blowing shop, was found to be completely satisfactory in field tests. |
