Special ly treated asbestos clothing has been de veloped which is impervious to metal splash up to 3,000 F. Requirements for asbestos and wool gar ments are m general the same as those for leather, except that metal fastenings should be covered with flaps to keep them from becoming dangerously hot The most common types of asbestos clothing are the leggings and aprons usual ly worn by foundrymen working with molten metal Such leggings should com pletely encircle the leg from knee to ankle, with a flare at the bottom to cover the in step.

Where men must work in extremely high temperature up to 2,000 F, such as furnace and oven repair, coking, slagging, fire fighting and fire res cue work, aluminized Mines are essential The aluminized coating reflects as much as 00 per cent of the radiant heat and the un derlying material insulates against the re mainder. Some of these suits consist of separate units of trousers, coats, gloves, boots, and hoods Others are one-piece from head to foot Some suits used in in dustrial operations are air-fed to reduce heat and increase comfort. Aluminized heat resistant clothmg gener ally falls into two classes 1. Fire entry surfs (Figs. 36-28 and -29) are used where the temperatures may ex ceed 1,000 F, as m a kiln or furnace, or where men must move through burning Fig 36-30.
