For any accident prevention work, engineering control is the best control, and aid of personal protective equipment (PPE) should be the last resort or a supplementary control. Nevertheless, the importance of personal protective equipment (PPE in short) is not less, its scope and utility have been tremendously increased during last few years and wide varieties of such equipment are available in the market. This requires proper selection of quality and utility for the specific purpose. The problem is not of the availability but is of its use by workers on the shop floors. Particularly in a country ours where the majority of workers are illiterate, not safety conscious and not trained to wear such equipment the problem becomes more acute mostly in small and medium scale factories.
The statistics of accidents exclusively due to non-use, misuse or defects of PPE is not available as there is no such distinct accident classification. 33% of total accidents could have been prevented by effective use of PPE. The conclusion is that @30 to 40% of total accidents can be prevented or controlled by the proper use of personal protective equipment. This figure is not small and highlights the need for PPE.
The PPE provides good defence against hazards of toxic exposure, oxygen deficiency, dusting, chemical splashes, steam, water and liquids, flying particles, hot substances, radiation, sharp edges, welding, cutting, grinding, striking against and stepping over objects, glare, personal falls and injury due to falling bodies, noise, scarp cleaning, material handling, opening of pipelines or any hazardous work, electric shocks, burn and firefighting. Many fatal accidents are caused due to these reasons and use of appropriate PPE can prevent or lessen many of them.
Limitation of the protection by PPE should be well understood. Respirators have limited use for the concentration and time mentioned by the manufacturer. they cannot be used in higher concentration for the longest time. In heavy concentration, only self-breathing apparatus (SBA) is recommended and that too for a limited time. Instead of providing hood and suction on flying particles, there is no meaning of giving respirator to the worker. Instead of providing a guard on a grinding wheel, it is meaningless to provide eye protection to workers. Instead of sealing leakage of gas or dust or allowing to continue it is unsafe to advise the worker to use a gas mask. Similarly, instead of trying to reduce pollution, it is of no use to tell the workers to use PPE only. It is always safer to improve the working conditions by engineering controls first. Then only the use of PPE may be recommended. It is the last line of defence.
PPE is a last line of defence. The first line is to eliminate or minimize workplace hazards. PPE cannot eliminate the hazard, it can help eliminate an injury or reduce its severity.
I remember a few fatal accidents from my investigation where I was of the opinion that besides engineering controls, PPE could have prevented such accidents. When an engineering control fails or becomes ineffective, what is the protection? Then this line of defence (i.e.PPE) comes to help and protect in most of the cases. In one case a worker died due to phosphine exposure and in another case due to chloroform vapor in a tank. In the third case due to a splash of 2-4 dichlorophenol, a worker died within 15 minutes. In still another case a worker died due to pesticide exposure in delayed effect. All four were young workers and died due to these toxic chemicals. If they would have worn appropriate PPE, they could have been survived. This shows the significance of the need for PPE. Through PPE cannot eliminate the hazard (like engineering control) it can certainly protect from it.
The need for PPE can be well judged from:
- Visual and foreseeable hazards.
- Accident experiences.
- Report on the safety committee/representatives.
- Safety audits, surveys, sampling, job safety analysis and risk assessment.
- Legal requirements and remarks of the authorities.
The need for PPE exists because:
- Chances of failure of engineering controls, materials, process, equipment and safety devices cannot be denied and in those circumstances, the PPE can act as a barrier between the man and hazard and save from the injury.
- There are certain operations or accidental situations where engineering controls are less possible and PPE becomes necessary. For repair or maintenance or to enter into toxic or oxygen deficient atmosphere, or while working at height or doing jobs like welding, cutting grinding, chipping, PPE gives good protection.
- It effectively avoids the contact of dangerous substances, noise, vibration and radiation.
- It protects from atmospheric contaminants.
- It is a legal as well as moral duty to provide suitable PPE.
STATUTORY PROVISIONS FOR SAFETY
No specific personal protective equipment is named by the Factories Act, but working conditions mentioned in sections 14, 30, 33, 35, 36, 37, 38, 87, 111, and 114 are such that free of charge PPE should be provided by the occupier for the protection from hazards due to dust, fume, gas, vapour, flying particles, glare, revolving machinery, hot or dangerous contents, entry in confined space, explosive or flammable atmosphere, fire, dangerous operations and hazardous process. Rules prescribed under the above sections provide further details. 27 schedules of Rule 102 of the Gujarat Factories Rules indicate the need of PPE at many places. Duty is cast upon the workers not to wilfully neglect to make use of such equipment and not to interfere with or misuse them. Model Rule 58 u/s 35 and Model Rule 95 u/s 87 also prescribe PPE for the specific process.
Rule 68B, GFR states that the PPE shall conform to the Indian Standards. OSHA standards prescribe tremendous details for PPE. Noise-induced hearing loss is an occupational disease under the 3rd Schedule of the Factories Act. Schedule 23 u/r 102, GFR requires noise reduction below 90 dBA or to provide ear protectors to workers and their auditory examination by the doctor. Sch. 27 required protection against cotton dust.

Glove material selection should be as under:
- Natural rubber gloves are stretchable and highly resistant to punctures. They perform well in mild caustics and ketone-based solutions and in temperatures ranging from
0 degree Farenheitto 300 degree farenheit. These gloves work well for jobwhich requires handling rough materials or sharp-edged objects such as plate glass and lumber.
- Neoprene is a premium-grade, synthetic rubber. Gloves coated with neoprene are resistant to strong acids, oils, grease, solvents
andcaustics, They perform well in temperatures from 0 degree farenheitto 300 degree farenheit.
- Nitrile is a super synthetic compound available in either a smooth or rough finish. They perform well in temperatures from 25
degree farenheitto 300 degree farenheit. Nitrile-coated gloves offer superior abrasion, snag and puntureresistance for tasks such as handling coarse building materials and rough castings.
- Viton gloves are especially useful for resisting chemical permeation from chlorinated and aromatic solvents as well as many other liquids and
- Polyvinylchloride (PVC) plastic gloves resist a broad range of chemicals and abrasives. They provide ample flexibility and durability in temperature ranging from 25
degree farenheitto 150 degree farenheit. PVC-coated gloves are ideal for jobs which involve handling rough machine parts, casting or petrochemical.
- Butyl rubber gloves offer high permeation resistance to many gases and
- Latex gloves are not appropriate for primary chemical resistance but offer good protection from standard grit/grime.
Utility and characteristics of hand protectors are:
|Leather gloves||Cuts, bruises, abrasions, lacerations during handling of metal sheets and other sharp-edged objects and sparks||Heat-resistant aluminised fabric or other special material|

Foot and Leg Protection:
Some typical risks are handling of heavy materials, caustic and corrosive liquids, wet conditions, molten metals, etc. Common foot and leg protective equipment are safety shoes or boots, leggings and foot-guards. Leg guards are used to protect-shins against impact. Knee pads are worn by mould loftmen and others who do continual kneeling. Selection is as follows:
Safety shoes/boots may be conductive, non conductive or spark resistant. Rubber boots are useful to work in wet conditions, steel toe boots against impact and puncture resistant soles to walk on surfaces having nails, sharp object etc.
Conductive shoes allow draining of static charge and non-ferrous shoes reduce possibility of friction sparks and much useful in fire/explosion prone area. Conductive footwear resistance should not exceed 450 kilo ohms.
Conductive shoes are used where floors are non-conductive and grounded such as in manufacture of certain explosive compounds or while cleaning tanks that have contained solvent or volatile hydrocarbons. These shoes have conductive soles and non-ferrous metal parts.
Foundary workers should wear gaiter or congress type safety shoes which have no fasteners or lashes and rapidly removable. The tops of the shoes should be covered by full pant leg, spats or legging to keep out molten metal.
Electricians need insulated shoes with non-metal parts. Leather shoes are useful to work in wet condition. Wooden soles to walk on hot surfaces and rubber shoes for working with acids and alkalis but not with solvents which dissolve the rubber.

Fall protection for the body includes safety belts, lifelines (ropes) and lanyards, harnesses (belts & straps with buckles) and fall-arrester devices or safety net.
It is important to note that such safety belts and associated equipments are used when fall hazards cannot be eliminated by strong support like railings, floors, platforms etc.
OSHA Standard has prohibited the use of a body belt only for fall arrest and a fall arrest system is suggested, since 1-1-1998.
Body belts are used where less than 1 m free fall is Full body harness anticipated and a body with safety belt and harness (belts or straps on fall arrester device chest, shoulders and thights) is used for a limited fall upto 2 m. A harness can spread the shock load over the shoulders, thights and seat (hips). The body belt or lifeline D-ring should be arranged at the back of the worker. The wearer of the safety belt should not tie off below waist level (to prevent turning down head). A window cleaner’s belt lenght is limited to 8 ft (2.5m). The chest belt is worn loosely to allow smooth breathing.
The lifeline may be vertical from a fixed anchorage or horizontal between two fixed anchorage
Independent of the work surfaces Lanyard is a flexible line up to 6 ft (1.8 m) to secure the wearer’s harness (D-ring) to a lifeline or fixed anchorage. Lanyards may be made of nylon or other fibrous or metallic material and non-strethable to limit free fall distance. Shock-absorber lanyards are available to absorb up to 80% of the stopping force of a normal lanyard. Metal lanyard must not be used where electrical hazard is possible. Snap hooks (locking type referable) and D-ring should be maintained in good condition. Knots or lengthening of lanyards must be avoided.
Body belts (work belts) are used to reduce the probability of falls. Chest harnesses are used where there is limited fall hazard (not vertical free fall) such as for removal of a person from a tank or bin. Body harnesses, covering chest, shoulders and thights, are used to arrest the most severe free falls.
Retrieval method is necessary to shorten the hanging distance after a fall upto 6ft (maximum limit of free fail for more fall height, other supporting fixed structure must be provided by fencing, railing, platform, fixed-ladder with platform and handrails etc.) Retractable lifeline, which will be shorten automatically (Spring action) after its full lenght, can limit falls to inches and avoid prolonged suspension causing high discomfort to a hanging person.
Fall arrester net, if used, should be tied firmly as near as possible under the working place to minimise the fall distance.
Belts, harnesses, lifeline, lanyards, buckles, joints, D-ring, etc. should be checked for weak points, washed regularly and kept
