EXHAVST SYSTEMS, GENERAL O COMFORT VENTILATION temperature plus large sources of radiated heat have been met by a suit of quilted ma terial faced with aluminized doth, a helmet with an infrared-reflective glass faceplate, and a self-contained air supply of com pressed gas With such an outfit, men have made emergency repairs in kilns, remaining almost indefinitely under temperatures up to 1,000 F.

IONIZING RADIATION proportion of about one nitrogen atom to twenty oxygen, to five carbon, and to fortyfive hydrogen atoms It is therefore impor tant to study the effects of radiation on water and on materials of a composition which resemble human tissue Irradiation of water produces large num bers of free electrons which have been ejected from the parent atoms, leaving posi tive ions In this process of ionization, there is dissociation of the water molecule and the release of oxidizing agents In die human body, there may be changes of struc ture of organic molecules and changes m the biochemical processes.

5--Removing the Hazard from the Job active cooperation of the safety professional In some instances, the purchase of ma chinery or equipment involves engineering de tails of great importance For such purchases, the industrial establishment will undoubtedly have a system whereby definite specifications, perhaps including drawings, will first be pre pared by engineers These plans and specifi cations will then be carefully checked by the safety professional before bids and estimates of cost are solicited The purchasing agent will have the plans and specifications at hand when he asks for prices However, he will want to keep in close touch with the safety professional throughout the negotiations in order to use the latter's knowledge and experience in ac cident prevention.
