Industrial Safety 29
hoisting devices must be equipped with limit switches for preventing loads block from over
traveling accidentally. Hoisting equipment especially cranes, should only be operated by properly
trained personnel for avoiding all sorts of mishaps or accidents. While operating a crane, the
operator should be entirely guided by standard signal and both operator and his signaler
should be thoroughly trained. Proper protections against fire and explosion hazards are
required when gasoline operated crains are being used. Where manual loading is done on
conveyors which run along a vertical path, either partially or totally, safe load sign should be
prominently displayed on all loading stations. Sufficient lighting, ventilation, drainage, escape
ways and guarding should be provided for conveyors which run in pits, tunnels and similar
other enclosures. Riding on a conveyor should always be prohibited. All the persons working
on or around the conveyor must wear tight cloths and safety shoes. All rotating, reciprocating
and projecting parts of machinery and equipments such as sprockets, gears, etc., should be
adequately protected by proper guarding. An effective lubrication schedule should be worked
out and implemented. All inspection should be carried out regularly and worn out parts, if
any, should be replaced immediately.
The workers should be properly trained to adopt safe working habits and proper supervision
should be done while these operations are being carried out manually. Industrial personnel
and unskilled workers should be adequately trained for adopting safe working habits in the
proper ways of lifting and setting down the objects. They should be told to be careful from
pinches and shear points and to grasp the articles firmly when lifting or setting down. Objects
which are wet or dirty or have slippery surfaces, such as greasy or oily and wet articles should
be completely wiped off dry before handling them. The hands should also be kept free of oil
and grease. For preventing hand injuries the handlers should be made to wear protective
clothing like leather hand gloves, sleeves, etc. The worker handling materials should always
wear foot in order to prevent foot injuries. If an object is to be lifted and carried to some
distance it should be ensured that the pathway is not slippery and there are no obstructions
on the passage or way. The unskilled industrial workers should be properly trained for
keeping correct positions of their feet, positions of back and knees, holding the object close
to the body while lifting and carrying, correct and firm grip, position of chin and application
of body weight in lifting and setting down by hand. This will help to prevent muscle strains
and back injuries. When a gang or team of workers is used to carry a heavy load form one
place to another the supervisor should ensure the use of proper tools and direct the work
himself to ensure proper synchronization in the lifting, walking and setting down actions of
all the workers involved. While transporting material by trucks, the truck should be operated
at safe limit speed as specified and special care should be taken at blind corners and doorways.
During storing material, it should be ensured that the electrical panels and installations and
fire extinguishers and hoses are kept clear and have free accessibility. Also the pathways,
entries and exits should always be kept clear for movement. The use of racks and bins
enables more storage capacity, easy movement of material from one place to another and
ensures better safety in an industrial organization
3.3.1 Objectives of Industrial Safety
The objectives of industrial safety are as follows:
1. Industrial safety is needed to check all the possible chances of accidents for preventing
loss of life and permanent disability of any industrial employee, any damage to
machine and material as it leads to the loss to the whole establishment.
2. It is needed to eliminate accidents causing work stoppage and production loss.
