Show Work In Intense Heat. 'Persons who complain of the heat when the thermometer reaches tho nineties," said a steamship engineer "seldom think of the discomforts of men employed In gas works. In blast furnaces and In steamMps, where the firemen have to endure an atmosphere ranging from 118 to 140 degrees. In all these and many otbr places where big boilers are located tho men wear very little clothing, and while they undoubtedly un-doubtedly suffer from the exposure, they do not feel the heat as much as might be supposed. The explanation of this fact Is that tbej.? men are Dot reached by the humidity. They aro working In places where the artificial heat Is so Intense as to drlvo out lh humidity, and 118 or more degrees of heat, in a pure, dry air Is not felt as much as a mixture of 00 degrees of heat and SO per cent of humidity, that tells on people and sorely tries their vitality." |
