Industrial Safety 35
14. Projecting nips between various links and mechanisms, like cranks, connecting
rods, piston rods, rotating wheels and discs, etc.
15. Projecting sharp edge or nips of belt and chain drives; via belt, pulleys, chains
sprockets and belt fasteners, spiked cylinders etc.
16. Nips between revolving control handles and fixed parts traverse gear handles of
lathes, millers, etc.
17. Moving balance weights and dead weight, hydraulic accumulators, counter-balance
weight on large slotting machines, etc.
18. Revolving drums and cylinders uncased, tumblers in the foundry, mixers, varnish
mixers etc.
19. Nips between fixed and moving parts such as buckets or hoppers of conveyors
against tipping bars, stops or parts of the framework.
20. Nips between revolving wheels or cylinders and pans or tables, sand mixers, crushing
and incorporating mills, mortar mills, leather carrying machines, etc.
21. Cutting edges of endless band cutting machines, wood working, and log cutting
metal find stone-cutting band saws, cloth-cutting band knives, etc.
22. Nips between gears and racks strips, roller drives, presses, planning machine drives,
etc.
3.7 PREVENTIVE MEASURES
Few safety measures commonly used in industries comprise of the proper safety guards for
reciprocating machine components such as drop hammers, presses, shaper, slotter, power
hacksaw, paper cutters etc., fencing of dangerous and rotating parts like revolving shafts,
incorporating safety devices such as safety valves, rigid construction of heavy items like
hoists, cranes etc, proper insulation of electric wire and earthing of electric appliances,
wearing appropriate safety shoe and other necessary items for, body protection, maintenance
cleanliness of shop floor, removal of metal chips with proper protection, avoiding fire hazard.
Safety while working safely in any shop is the safety of human being and the safety of
workshop machinery. Hence there is a great need for the study of the domain of industrial
safety for accidents prevention and good house keeping is the utmost. Safe working conditions
in any industry may help to minimize the number of accidents taking place, prevent premature
death of talented employee, prevent needless pain and suffering to industrial employees,
reduce damages to equipment and machinery, increase production and reduce production cost.
Good housekeeping implies keeping industry clean, look pleasant well illuminated and ventilated
so that accidents are minimized, total production and quality are improved and the employee
morale is boosted. Careless handling of heavy materials and components is a major source
of back and foot injuries. To avoid premature fatigue of transport workers, full use should be
made of mechanized materials handling equipment. Use mechanical means of conveyance to
ensure the safety of men engaged in material handling. The transport workers should not be
asked to lift more than the permissible load. Personal protective devices such as safe hard
hats, rubberized hats for protection against liquids /chemicals, ear protectors, face mask/face
shields, welding helmet, goggles of case-hardened and clear glass for protection against impact
should be used as per the need.
