Industrial Accidents: Types and Causes of Accidents (explained with diagram)

Industrial Accidents: Types and Causes of Accidents (explained with diagram)!
The ever increasing mechanisation, electrification, chemicalisation and sophistication have made industrial jobs more and more complex and intricate. This has led to increased dangers to human life in industries through accidents and injuries. In fact, the same underlines the need for and importance of industrial safety. Let us first understand what industrial accident actually means.

Industrial Accident:

An accident (industrial) is a sudden and unexpected occurrence in the industry which interrupts the orderly progress of the work. According to the Factories Act, 1948: “It is an occurrence in an industrial establishment causing bodily injury to a person who makes him unfit to resume his duties in the next 48 hours”.
In other words, accident is an unexpected event in the course of employment which is neither anticipated nor designed to occur. Thus, an accident is an unplanned and uncontrolled event in which an action or reaction of an object, a substance, a person, or a radiation results in personal injury. It is important to note that self-inflicted injuries cannot be regarded as accidents.
An industrial injury is defined as “a personal injury to an employee which has been caused by an accident or an occupational disease and which arises out of or in the course of employment and which could entitle such employee to compensation under Workers’ Compensation Act, 1923”.

Types of Accidents:

Accidents may be of different types depending upon the severity, durability and degree of the injury. An accident causing death or permanent or prolonged disability to the injured employee is called ‘major accident. A cut that does not render the employee disabled is termed as ‘minor’ acci­dent. When an employee gets injury with external signs of it, it is external injury.
Injury without showing external signs such as a fractured bone is called an internal one. When an injury renders an injured employee disabled for a short period, say, a day or a week, it is a temporary accident. On the contrary, making injured employee disabled for ever is called permanent accident. Disability caused by accident may be partial or total, fatal or non-fatal.
The various types of accidents are now shown in Figure 20.1.

No accident occurs automatically. Instead, certain factors cause accidents. It has been noticed that an accident does not have a single cause but a multiplicity of causes, which are often closely related. The same is discussed subsequently.

Causes of Accidents:

The industrial safety experts have classified the various causes of accidents into three broad categories:
1. Unsafe Conditions
2. Unsafe Acts
3. Other Causes?
These are discussed, in brief.

1. Unsafe Conditions (work-related):

Unsafe working conditions are the biggest cause of acci­dents. These are associated with detective plants, tools, equipment’s, machines, and materials. Such causes are known as ‘technical causes’. They arise when there are improper guarded equipment’s, defective equipment’s, faulty layout and location of plant, inadequate lighting arrangements and ventilation, unsafe storage, inadequate safety devices, etc.
Besides, the psychological reasons such as working over time, monotony, fatigue, tiredness, frustration and anxiety are also some other causes that cause accidents. Safety experts identify that there are some high danger zones in an industry. These are, for example, hand lift trucks, wheel-barrows, gears and pulleys, saws and hand rails, chisels and screw drivers, electric drop lights, etc., where about one-third of industrial accidents occur.

2. Unsafe Acts:

Industrial accidents occur due to certain acts on the part of workers. These acts may be the result of lack of knowledge or skill on the part of the worker, certain bodily defects and wrong attitude.
Examples of these acts are:
(a) Operating without authority.
(b) Failure to use safe attire or personal protective equipment’s,
(c) Careless throwing of material at the work place.
(d) Working at unsafe speed, i.e., too fast or too low.
(e) Using unsafe equipment, or using equipment’s unsafely.
(f) Removing safety devices.
(g) Taking unsafe position under suspended loads.
(h) Distracting, teasing, abusing, quarrelling, day-dreaming, horseplay
(i) One’s own accident prone personality and behaviour.

3. Other Causes:

These causes arise out of unsafe situational and climatic conditions and variations. These may include excessive noise, very high temperature, humid conditions, bad working conditions, unhealthy environment, slippery floors, excessive glare, dust and fume, arrogant behaviour of domineering supervisors, etc.
Of late, industrial accidents have become common happening in our country. A brief catalogue of major accidents in the recent past in India is produced here:
Exhibit 20.1 Major Accidents in the Last Decade:
Bhopal, December 1984: In world’s worst chemical disaster, a methylisocyanate gas leak from the Union Carbide plant in the city killed over 4000 people. Thousands suffered irreversible health damage.
Delhi, December 1985: An oleum gas leak from the Sriram Foods and Fertilisers Plant in Delhi severely affected workers and those living in the neighbourhood.
Rourkela, December 1985: Blast furnace accident in Rourkela Steel Plant. 18 workers affected.
Durgapur, June 1987: Chlorine leak at Durgapur Chemical Factory created panic all around. Long distance trains were halted. Over 100 were affected.
Bombay, November 1988: Fire at the Bharat Petroleum Refinery at Mahul, north-east Bombay, killed 32.
Ramagunaam, September 1989: Major gas leak at Fertilisers Corporation of India unit at Ramagundam, killed 7.
Nagothane, November 1990: Explosion at the Indian Petrochemicals, Nagothane com­plex, 35 persons killed, over 50 suffered 70 per cent bums.
Bombay, July 1991: Accident in a Hindustan Organic Chemicals unit near Bombay kills 7 workers.
Gwalior, December 1991: Blast at the dyeing department of GRASIM unit at Gwalior. 14 Killed and 22 severely injured.
Panipat, August 1992: Ammonia leak at the National Fertilisers Plant, Panipat killed 11, many injured.
Kahalgaon, October 1992: Boiler explosion in the National Thermal Power Corporation (NTPC), 11 killed and several injured.
It is reported that in every twenty seconds of every working minute of every hour throughout the world, someone dies as a result of an industrial accident. Industrial accidents cause losses to the employees and organisations as well. Table 20.1 gives an idea about the enormous losses that acci­dents have caused to the industrial establishments in our country.
Table 20.1: Accidents—Estimated Loss:
 
Accidents causing losses to the industrial establishments need to be avoided. Adequate safety measures can avoid accidents. The subsequent discussion focuses on certain questions: What? Why?, and How safety?

Safety:

In simple words, safety means freedom from the occurrence or risk of injury or loss. As regards, industrial safety, it means the protection of employees/workers from the danger or risk of industrial accidents. In other words, industrial safety refers to protection against accidents occurring in the industrial establishments.
