22 Materials and Their Handling 



must be considered. The kind of container will 

 be determined by the material. In general, bins 

 or square boxes arc more economical of space 

 than barrels or drums, because the circular shape 

 of the latter leaves much open space in between. 

 Liquids may be contained in barrels or cans, or 

 carried in bulk. If inflammable, as in the case 

 of fuel oil, gasoline, etc., it may be necessary to 

 store them outside of the buildings. These should 

 be stored, not only outside, but in tanks so far 

 underground that if the tanks leak or pipes burst, 

 there can be no flow into any part of the buildings. 

 An overhead tank with a gravity feed is a deadly 

 fire hazard. The effect of gravity should be to 

 drain the pipes back into the underground tank 

 and the oil should be pumped up to the point 

 where it is needed. 



Only the rougher kinds of materials should be 

 exposed to weather. Materials which are affected 

 by heat must be kept in rooms where a given tem- 

 perature range is maintained. Many materials 

 are injured if subjected to acid fumes finished 

 machine parts, for example. These should not 

 be stored near pickle tubs nor a plating room, as 

 the fumes may damage them in a very short time. 



Fire Protection in the Storeroom. The ele- 

 ment of fire protection must constantly be borne in 

 mind, not only in the lay-out of the storeroom, but 

 also in the daily work about the storeroom. All 

 dangerous material should be segregated, to re- 

 move its menace from the rest of the plant. Lubri- 

 cating and cutting oils should be carefully handled,
