Occupational Safety Training for Operating a Blower

1. Overview of Blower Machines

a. What is a Blower Machine?

A blower machine is a mechanical device used to generate airflow or air pressure in a specific system or application. Blowers are commonly used to supply air for industrial processes, ventilation systems, cooling, waste treatment, or other applications that require specific air pressure or airflow.

Blowers usually operate by using a rotating fan or impeller to move air. The impeller creates pressure and pushes air out or draws air in, depending on the design and specific application. The blower can be controlled to adjust air pressure and flow according to system requirements.

Common applications of blower machines include building ventilation systems, wastewater treatment, aeration during composting, drying in manufacturing processes, and many other industrial uses.

b. Operating Principle of Blower Machines

The operation of a blower is based on the principle of a rotating fan or impeller creating pressure and airflow. Here is a basic description of how a blower works:

• Impeller: A blower has one or more impellers (fan blades). The blades are mounted on a rotating shaft, and when the blower operates, the shaft rotates, moving the blades through the air.
• Air intake and discharge: As the blades rotate, they create a low-pressure area behind them, drawing air in through an intake. The blades then push the air forward, generating high pressure.
• Air compression: The high pressure created by the blades is used to compress the air. The compressed air is discharged through an outlet. The pressure and airflow can be controlled by adjusting the blade rotation speed or other control devices.

c. Industries Using Blower Machines

Blower machines are widely used across various industries and applications. Key industries include:

• Wastewater treatment: Blowers supply air in wastewater systems such as activated sludge, biological filtration, and toxic gas treatment systems.
• Food and beverage industry: Blowers are used in composting waste and in food and beverage production, e.g., brewing, alcohol, and dairy production.
• Chemical industry: Blowers provide air for chemical processes and waste treatment in the chemical sector.
• Manufacturing and processing: Blowers are used for drying or cleaning during production, such as in paper manufacturing, animal feed production, and oil & gas industries.
• Healthcare: Blowers are used in medical equipment, such as air supply systems for patients or air filtration in operating rooms and cleanrooms.
• Electrical and electronics: Blowers assist in drying electronic products or cleaning electronic components.
• Energy industry: Blowers are applied in energy-related processes, e.g., drying in solar power projects or biofuel production.
• Mining and mineral industry: Blowers are used to clean mined products or supply air during mineral processing.

2. Overview of Safety Training for Blower Operation

a. What is Labor Safety Training?

• Labor safety training for blower operation equips workers with awareness to prevent workplace accidents. Workers directly handling blowers belong to Group 3.
• Safety training helps workers identify and avoid hazards, reducing the risk of workplace accidents.

b. Training Duration

Initial Safety Training

• Total training time is at least 24 hours, including assessment.
• 8 hours of theory on policies and labor safety laws
• 8 hours of basic occupational safety and hygiene theory
• 4 hours of specialized training theory
• 2 hours of practical specialized training
• 2 hours for final theoretical assessment

Training sessions are scheduled depending on worker availability, usually 6 sessions over 3 days, if continuous training time is feasible.

Periodic Safety Training

• Before the labor safety card expires, workers must complete periodic training, with at least 50% of the initial training duration.

Explanation: The total duration for periodic safety training is at least 12 hours, including assessment. After successful completion, the labor safety card is renewed.

d. Labor Safety Card

Upon completion of training and passing the assessment, workers receive a labor safety card (commonly called a Group 3 safety certificate).

The Group 3 card includes personal details, job, work environment, training duration, official stamp, and signature confirming completion.

According to Clause 2, Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the worker has a labor contract with the employer, the employer must sign and stamp the safety card after training and passing the test.
• If the worker is freelance or seasonal without a labor contract, the training unit must sign and stamp the safety card after the worker completes training and passes the test.

3. Hazards When Operating Blower Machines

When operating a blower machine, there are several hazards and safety issues to consider to ensure the safety of workers and equipment. Below are some common hazards when operating a blower machine:

• High temperature and pressure: Blower machines can generate high temperatures and pressures during operation. Improper operation may cause fire, explosion, or injury to workers.
• Contamination and impurities: The air or gas compressed by the blower may contain impurities or dust. This can lead to fire or explosions if flammable materials are present in the environment.
• Electrical voltage and hazards: Electric blowers can pose electrical risks if not properly maintained or operated. Electrical shocks can cause accidents or fires.
• Noise: Blower machines often generate loud noise during operation. Workers need protection from excessive noise to prevent hearing damage.
• Operation and maintenance: If the blower is not regularly maintained or operated correctly, it can cause malfunctions or fire hazards.
• Toxic gases: Blower machines may operate in environments with toxic gases. Workers need training to identify and handle risks related to toxic gases.
• During repair or maintenance, workers must use appropriate safety tools and equipment to avoid accidents.

4. Measures to Prevent Workplace Accidents When Operating Blower Machines

To prevent workplace accidents when operating blower machines, a series of safety measures and risk management practices should be implemented. Key measures include:

• Training: All employees involved in operating blower machines must be properly trained on usage, maintenance, and safety. Training should include potential hazards and how to address them.
• Personal protection: Ensure that employees use personal protective equipment (PPE) such as safety glasses, helmets, hearing protection, and protective clothing as required when working with blower machines.
• Inspection and maintenance: Conduct regular inspections and maintenance of blowers according to manufacturer instructions or industry regulations. Ensure the blower is always in safe working condition.
• Noise management: If the blower produces loud noise, provide hearing protection for employees using earplugs or soundproofing materials.
• Environmental conditions: Keep the working environment around the blower clean, free of impurities or flammable chemicals. Provide ventilation and manage toxic gases as needed.
• Temperature and pressure risks: Implement safety measures to control temperature and pressure during blower operation. Use sensors and safety systems to monitor and regulate these parameters.
• Toxic gas management: If operating in environments with toxic gas, ensure employees are trained to identify and handle toxic gases and use appropriate PPE.
• Follow safety procedures: Ensure specific safety procedures for blower operation are established and always followed. This includes start-up and shutdown procedures, emergency handling, and daily safety checks.
• Compliance with standards: Follow all relevant safety regulations and standards related to blowers in the workplace.
• Building a safety culture: Promote a safety culture within the organization, encouraging incident reporting and safety improvement suggestions.
• Periodic inspection of blowers to detect safety issues such as mechanical wear or defects, reducing the risk of workplace accidents.
