It does not lead to disability or infection. (5) In estimating the possible effects of any given industrial substance, it is necessary to know its chemical nature. (6) It now appears that certain silicates which were once considered as inert may became noxious when subjected to high temperatures. (7) Certain metals when subjected to high temperatures, liberate their oxides which may produce chemical pneumo nitis. (8) An industrial environment per se does not induce tuberculosis. -- Author's summary 289 Pathogenesis of Industrial Pulmonary Disease.

It is impossible to install a water gage glass on an inverted bucket trap, but if visual inspection is necessary, a gage glass can be placed on the line leading to the trap.

A comparison between the perform ance of two designs, unless based on such tests on each, may lead to entirely erroneous conclusions.

Toxic Dust Type Respirators are approved for protection against inhalation of toxic or piosonous dusts, such as lead, cadmium, arsenic, chromium, manganese, selenium, vanadium and their compounds.

The air volume should be sufficient to maintain a velocity of not less than 100 fpm over the open area of the booth (150 fpm is preferable where benzol or lead is present in the paint) and the vapors should be discharged through a suitable stack to permit dilution.

Supply Mains (.Steam): The pipes through which the steam flows from the boiler or source of supply to the run-outs and risers leading to the heating units.

If the pipes leading to it are large enough, it will be easy to secure sufficient circulation for the other two radiators.

It is not clear from the description whether his lungs were normal when examined histologically after death or whether they showed asbestosis: the history of this worker does, however, show that prolonged exposure does not necessarily lead to any disability.
