1. Overview of Steel Sheet Rolling Machine
a. What is a Steel Sheet Rolling Machine?
A Steel Sheet Rolling Machine is an industrial device used to transform the shape of steel sheets. This rolling process is typically performed to create products with specific shapes and sizes, such as steel sheets, steel pipes, or other structural components.
The operating principle of a steel sheet rolling machine usually involves placing a steel sheet between two rollers and applying compressive force to change its thickness and shape. This process can be repeated multiple times with specific settings to achieve the desired result. Rolling machines can be adjusted to form steel into different shapes, depending on production requirements.
Applications of steel sheet rolling machines are diverse and may include the production of construction structural components, shipbuilding, automotive manufacturing, and many other industrial fields.
b. Operating Principle of Steel Sheet Rolling Machine
The operating principle of a steel sheet rolling machine involves applying compressive force to a steel sheet to change its thickness and shape. Below is an overview of how the machine operates:
- Placing the steel sheet: A steel sheet is positioned between the two rollers of the machine.
- Compressive force: The upper and lower rollers apply pressure, generating high force on the steel sheet. This force is adjusted to meet specific rolling requirements.
- Shape transformation: The compressive force deforms the steel sheet and reduces its thickness. If necessary, the process can be repeated multiple times with varying pressure to achieve the desired result.
- Rolling stages: Rolling machines often have multiple stages, with each stage using a different pair of rollers to refine the steel sheet’s shape.
- Control system: The rolling process is typically managed by automated systems to ensure accuracy and uniformity of the final product.
c. Industries Using Steel Sheet Rolling Machines
Steel sheet rolling machines are widely used across various industries to produce steel products in different shapes and sizes. Some major industries using these machines include:
- Construction: Used to produce steel sheets and structural components such as columns, beams, and other construction elements.
- Shipbuilding: Used to manufacture parts of ship hulls, containers, and other structural components.
- Automotive: Plays an important role in producing car panels, frames, and other automotive components.
- Energy: Used to produce steel pipes and components for oil, gas, and renewable energy industries.
- Machinery and Equipment Manufacturing: Used to produce parts for industrial machinery and equipment.
- Processing Industry: Used in various manufacturing processes, such as producing household appliances and other required components.
2. Overview of Occupational Safety Training for Operating Steel Sheet Rolling Machines
a. What is Occupational Safety Training?
- Occupational safety training for operating steel sheet rolling machines provides workers with awareness on preventing workplace accidents. Workers directly operating these machines belong to Group 3.
- The safety training course helps workers identify and prevent hazards, reducing the risk of workplace accidents.

b. Training Duration
Initial safety training duration:
- Total training time is at least 24 hours, including testing time.
- 8 hours of theory on safety and labor hygiene policies and laws
- 8 hours of theory on basic occupational safety and hygiene knowledge
- 4 hours of theory on specialized training content
- 2 hours of practical training on specialized content
- 2 hours of theory test at the end of the course
The training center schedules sessions depending on workers’ availability, typically in 6 sessions over 3 days, provided the company arranges continuous training time.
Periodic safety training duration:
- Before the occupational safety card expires, workers must undergo periodic occupational safety training, with the duration being at least 50% of the initial training time.
Explanation: total periodic safety training time is at least 12 hours, including testing. After completing the course and passing the test, workers are reissued and renewed their occupational safety card.

d. Occupational Safety Card
After completing the training course and passing the test, workers will be issued a Occupational Safety Card (commonly referred to as Group 3 Safety Certificate).
The Group 3 safety card displays information such as full name, date of birth, specific job and work environment, training duration, official stamp, and signature confirming course completion.
According to regulations in Clause 2, Article 24 of Decree 44/2016/ND-CP, there are two cases:
- If the employer and employee have a labor contract, the employer must sign and stamp the safety card for Group 3 employees after they complete the training and pass the test.
- If the worker is freelance or seasonal with no labor contract, the training unit must sign and stamp the safety card after the worker completes the training and passes the test.

3. Hazards When Operating Steel Sheet Rolling Machines
Operating steel sheet rolling machines can involve numerous hazards due to the nature of the work and the working environment. Below are some common hazards when operating steel sheet rolling machines:
- Injuries from machinery: Moving parts of the rolling machine, such as rollers and transmission systems, can pose injury risks if workers do not follow safety rules or are not properly trained.
- Heat hazards: The rolling process often generates high temperatures. Uncontrolled heat can cause fire or explosions or degrade machine components.
- Crushing and deformation hazards: Rolling machines can produce high pressure, and without proper safety measures, workers risk being crushed, deformed between rollers, or trapped in machine parts.
- Chemical hazards: Coating and surface treatment processes may use toxic chemicals, posing health risks if safety measures are not followed.
- Noise and vibration hazards: Rolling machines generate noise and vibrations that can affect workers’ health if ear protection and anti-vibration equipment are not used.
- Fire hazards: High temperatures and work processes can increase fire risks. Maintaining fire prevention and emergency measures is crucial.
- Lack of safety training and awareness: High risk occurs when employees are not properly trained in workplace safety and machine operation procedures.
