Abstract :
PROTECTIVE lighting is not a new practice grown out of the present war program. It has been in use for the past 25 years and is better known as yard lighting. It has been used by generating plants to prevent raids on the coal pile, in silk mills to prevent theft of valuable merchandise, in automobile factories to prevent theft of storage batteries, tires and other readily saleable parts. Yard lighting has been universally used by steel plants to prevent yard accidents and by many plants as a means of protection of property during strikes. In some industries, such as shipbuilding and structural steel plants and oil refineries, much of the production work is carried on out-of-doors, and yard lighting has been used to facilitate production, storage, and shipping. During war times, theft, fire, strike damage, and interruption of production become “sabotage,” and so yard lighting takes on a new name — protective lighting, referring to protection of property — material, facilities, and life and limb. The chief difference is that loss from sabotage is greater and industry can ill afford the loss in such times.
