1. Overview of Steel Sheets
a. What are Steel Sheets?
- Steel roofing sheets (also called corrugated steel roofs) are materials used to cover and protect buildings, houses, warehouses, factories, restaurants, schools, hospitals, industrial parks, farms, and other constructions from external weather elements such as rain, sun, wind, snow, and ice.
- Steel roofing sheets are usually made from galvanized steel, cold-rolled steel, color-coated steel, aluminum-zinc steel, and other materials, but galvanized steel is the most commonly used in the construction industry. They offer many advantages such as durability, aesthetics, light weight, easy installation, and lower cost compared to other materials.
- However, using steel roofing sheets also requires safety precautions during installation and use to prevent accidents such as falls from height, slips, trips, and injuries. It is necessary to fully comply with occupational safety regulations and use protective equipment correctly when working with steel sheets.
b. Machinery for Steel Sheet Manufacturing
The machinery used in steel sheet manufacturing includes:
- Rolling machine: Used to roll steel sheets into thick or thin sheets with different widths and thicknesses. Rolling machines are typically used to manufacture roofing sheets for construction projects.
- Cutting machine: Used to cut steel sheets into pieces of various sizes and shapes to meet customer requirements. Cutting machines are commonly used to produce roofing sheet pieces for construction projects.
- Welding machine: Used to weld steel sheet pieces together to form larger parts or sheets. Welding machines are used to manufacture roofing components for buildings.
- Bending machine: Used to bend steel sheets into different shapes according to design requirements. Bending machines are used to produce curved roofing sheets or roofing accessories.
- Pressing machine: Used to press steel sheets into different shapes to match design specifications. Pressing machines are used to manufacture roofing accessories for construction projects.

b. Training Duration
Initial Safety Training
- Total training duration is at least 24 hours, including testing time.
- 8 hours of theory on occupational safety policies and laws
- 8 hours of theory on basic occupational safety knowledge
- 4 hours of theory on specialized training content
- 2 hours of practical exercises on specialized content
- 2 hours of final theoretical test
Training centers schedule multiple sessions depending on workers’ availability. Typically, 6 sessions over 3 days are arranged, provided the manufacturing company allocates continuous training time.
Periodic Safety Training
- Before the occupational safety card expires, workers must undergo periodic safety training, with periodic training duration at least 50% of the initial training duration.
Explanation: The total periodic training duration is at least 12 hours, including testing. After completing the periodic training and passing the test, workers receive a renewed occupational safety card.

d. Occupational Safety Card
After completing the occupational safety training and passing the test, workers will be issued a Group 3 occupational safety card (commonly called occupational safety certificate).
The card shows full name, date of birth, job, and workplace, as well as training duration, red stamp, and signature confirming completion.
According to Clause 2 of Article 24, Decree 44/2016/ND-CP, there are 2 cases:
- If an employment contract exists, the employer must sign and stamp the card after the worker completes training and passes the test.
- If the worker is freelance or temporary without a contract, the training unit must sign and stamp the card after completion and passing the test.

3. Identifying Hazards Affecting Workers in Factory Manufacturing of Steel Sheets
The hazards affecting workers in the factory manufacturing of steel sheets include:
- Steel sheet manufacturing often involves the use of equipment and machinery operating in environments with gases and flammable liquids. Therefore, the risk of fire and explosion can always occur during manufacturing.
- Tasks during steel sheet manufacturing such as cutting, grinding, pressing, and welding can cause accidents like cuts on hands, burns, or eye injuries due to dust or other materials.
- Steel sheet manufacturing can cause environmental pollution due to the use of chemicals and toxic substances during the manufacturing process.
- Using large machinery and equipment in steel sheet manufacturing can generate noise and vibrations, affecting workers’ health.
- Materials used in steel sheet manufacturing during cutting, grinding, and welding can release dust and toxic fumes, posing health risks to workers.
- Equipment and machinery in a factory producing steel sheets may create fall hazards if not properly maintained and regularly inspected.
- If electrical equipment in the factory is not regularly maintained, sufficiently insulated, or waterproofed, it can pose the risk of electric shock to workers during manufacturing.
4. Common Occupational Accidents for Workers in Steel Sheet Manufacturing
Common occupational accidents in steel sheet manufacturing include:
- Fire and explosion accidents: Steel sheets are produced through heating, rolling, and thermal processes, so the risk of fire and explosion in the factory is very high. Chemicals used in steel sheet manufacturing, such as oil, gas, solvents, and other liquids, also increase the risk of fire and explosion.
- Injury accidents: Steel materials are moved and transported during manufacturing. If not careful, accidents can occur when they collide or fall on workers. Additionally, operating steel sheet manufacturing machinery also carries a risk of injury.
- Health hazards: The steel sheet manufacturing process often produces dust and toxic fumes that can harm workers’ health, especially if they do not wear sufficient personal protective equipment.
- Fall accidents: Activities such as climbing on equipment or moving steel sheets can lead to falls, especially when workers do not wear proper protective gear or follow occupational safety regulations.
- Piercing or collision accidents: During manufacturing, moving machinery and materials without caution can lead to piercing or collision accidents, especially if workers do not wear protective gear and follow safety rules.
5. Safety Measures When Participating in Steel Sheet Manufacturing
To ensure workers’ safety during steel sheet manufacturing, the following measures should be implemented:
- Training: Provide workers with complete knowledge and skills before starting steel sheet manufacturing tasks.
- Use of protective equipment: Ensure all machinery and equipment are equipped with protective devices, such as gloves, safety glasses, masks, safety belts, etc.
- Equipment maintenance: Ensure all machinery and equipment are periodically maintained and inspected to guarantee safe and efficient operation.
- Safety inspections: Conduct regular safety inspections to detect and address safety and health issues for workers.
- Applying occupational safety regulations: Comply with state occupational safety regulations and specific company rules to protect workers’ safety and health.
- Adjusting transportation methods: Adjust transportation means to ensure physical safety and a safe working environment for workers.
- Creating a safe workspace: Develop a safe and organized working environment, including arranging machinery and equipment to ensure workers’ comfort and safety.
- Regularly conducting occupational environmental monitoring in factories, collecting and analyzing harmful factors, and adjusting to reduce hazards to prevent occupational diseases for workers.
