Restrict traffic through storage areas to decrease chances of chemical contamination and spillage. Assign the responsibility for maintaining and distributing raw materials to one person. Purchase raw materials according to actual need, thereby avoiding partly used containers of material from becoming unusable while in storage. Ordering materials in returnable bins reduces or eliminates the need for cleaning. Test expired materials for usefulness.
Many chemicals are usable well beyond their expiration dates.
Extending Metal Working Fluid Life Regularly replace seals and wipers to avoid contamination of metalworking fluids by tramp oil. Cover sumps with screens or solid covers to reduce the contamination of fluids by cigarette butts, food, food wrappers and other litter. Establish a concentrated program for maintaining sumps. Regular cleaning of the sumps will result in extended and more efficient performance, and thus significant monetary savings. Use high quality, stable cutting, and grinding fluids.
