The leadinglamp manufacturers upon being acquainted of this fact inaugu-rated a survey of their own. with a view towards finding out if it lO UGHTING OP THE FOOD INDUSTRIES really was dangerous to use the incandescent lamp in such interi-ors and how they could best be applied with safety. A recapitula-tion of the results of this survey was presented before the societyduring the Annual Convention September 26-2gth, 1921, in a paperentitled Incandescent Lamp Temperatures as Related to ModernLighting Practice. As was pointed out at that time, it wasfound that fires or explosions which may be caused by incan-descent lamps in dusty atmospheres are of two kinds. First: In extreme cases, fires resulting directly from the ig-nition of dust accumulating on the lamp ,c ^!\l~A I r ^^8 typical conditions encountered in a grain elevator, rlZ. .\ /° P^^^ ^^^^^ ° ^-^-« - - 4 feet Absence o^ [ r 1 ^^^7l«t,on results in decidedly low utilization of light, averagenenity less than o^s ft-c.
