Safety in Steel Plant: Why It Matters and How to Achieve It
Steel is one of the most important materials in the modern world, used for various applications ranging from construction, industrial machinery, consumer products, and more. However, producing steel is not an easy task, as it involves many potential hazards that can pose serious risks to the workers, the environment, and the public. Therefore, safety in steel plant is a crucial aspect that needs to be given utmost priority and attention by all the stakeholders involved in the steel industry.
What are the hazards in steel plant?
According to the Ministry of Steel, Government of India, the steel industry has been classified as a hazardous process industry as per Chapter 1 Sec-2 (cb) of Factories Act 1948 (Amended in 1987)¹. Some of the common hazards in steel plant are:
- Fire and explosion: Steel making involves high temperatures, flammable gases, and combustible materials, which can cause fire and explosion if not handled properly. Some of the sources of fire and explosion are molten metal, slag, coke oven gas, blast furnace gas, oxygen, hydrogen, acetylene, etc.
- Electric shock: Steel plant uses a lot of electrical equipment and machinery, which can expose the workers to the risk of electric shock if there is any defect, damage, or improper maintenance. Some of the sources of electric shock are electric arc furnace, induction furnace, ladle furnace, transformers, motors, cables, etc.
- Noise and vibration: Steel plant generates a lot of noise and vibration due to the operation of various machines and processes, which can cause hearing loss, stress, fatigue, and other health problems to the workers. Some of the sources of noise and vibration are rolling mills, forging hammers, crushers, fans, blowers, compressors, etc.
- Heat stress: Steel plant exposes the workers to high temperatures and humidity, which can cause heat stress, dehydration, heat exhaustion, heat stroke, and other heat-related illnesses. Some of the sources of heat stress are furnaces, ladles, converters, casting machines, etc.
- Chemical exposure: Steel plant involves the use of various chemicals and substances, which can cause skin irritation, eye injury, respiratory problems, poisoning, and other health effects to the workers. Some of the chemicals and substances are acids, alkalis, solvents, lubricants, oils, dust, fumes, gases, etc.
- Mechanical hazards: Steel plant involves the movement of heavy and sharp objects, which can cause cuts, bruises, fractures, amputations, and other injuries to the workers. Some of the mechanical hazards are cranes, hoists, conveyors, rollers, shears, presses, etc.
- Ergonomic hazards: Steel plant requires the workers to perform various tasks that can cause musculoskeletal disorders, such as back pain, neck pain, shoulder pain, etc. Some of the ergonomic hazards are lifting, pushing, pulling, bending, twisting, reaching, etc.
- Radiation hazards: Steel plant uses some sources of radiation, such as X-rays, gamma rays, etc., which can cause cancer, genetic damage, and other health effects to the workers. Some of the sources of radiation are radiography, thickness gauges, level gauges, etc.
How to achieve safety in steel plant?
To achieve safety in steel plant, it is essential to adopt a systematic and proactive approach that involves the following steps:
- Identify the hazards: The first step is to identify the hazards that are present in the steel plant, and assess their severity and probability of occurrence. This can be done by conducting regular inspections, audits, surveys, etc., and using tools such as hazard identification and risk assessment (HIRA), failure mode and effect analysis (FMEA), etc.
- Eliminate or control the risks: The second step is to eliminate or control the risks that are associated with the hazards, as far as it is reaso
