Occupational Safety Training in Confined Spaces

1. Overview of confined spaces

a. What is a confined space?

• A confined space work environment is a work environment that does not have enough space or enough wide space for employees to work comfortably and safely. This can occur in many occupations, such as in computer rooms, manufacturing workshops, vehicles, or construction sites.
• In a confined space work environment, employees may have to work in small, enclosed, narrow spaces or in hard-to-reach locations, such as high, deep, or underground areas. Working in a confined space can cause a number of health, safety, and psychological problems for employees, so it requires occupational safety measures and proper work procedures.

b. Types of environments called confined spaces

The types of work environments called confined spaces include:

• Computer room: This is the main work environment for technical staff or technical support staff, where they have to work in a small, narrow space, with little air, and the air pressure is often kept at a higher level than the outside environment.
• Electrical system control room: is a special room designed to control, monitor and maintain electrical systems in a building, a factory or a manufacturing facility. It is the control center for electrical equipment, machinery, measuring devices and other electrical systems used in the manufacturing process, ensuring safety and efficiency for the entire electrical system.
• Mine shaft: this is a work environment in confined spaces with poor air circulation and high humidity, which can be dangerous to the health of those who work in it.
• Sewerage is a natural environment in drainage and wastewater treatment systems. It includes culverts, pipes and drainage channels used to move water and waste from factories, residential areas, schools and industrial facilities to wastewater treatment plants.
• Pipeline: Working in a gas pipeline is a job that requires high skills and experience, especially when the space in the pipeline is narrow. Workers must be well prepared and follow safety procedures to ensure their lives and health.
• Well: Working in a deep well is a dangerous job and there is a risk of health problems, especially when there are no proper safety measures. The main dangers of working in a deep well include: lack of oxygen, fire and explosion, toxins…
• Tank: is a type of construction with the function of containing liquid or gas in a confined space, often used in the chemical, petroleum, food and beverage industries. However, due to the limited space, many risks related to health and occupational safety can occur when working in a tank with a narrow space.

c. Specific jobs in confined spaces

Specific jobs in confined spaces often involve working in cramped spaces, limited movement and air. These jobs often include:

• Installing and repairing electrical, water, and gas systems in cramped spaces such as under stairs, in walls or on ceilings.
• Repairing and maintaining equipment such as air conditioners, heaters, water pumps, electronic devices in confined spaces.
• Installing and repairing lighting systems in confined spaces.
• Painting and plastering surfaces in confined spaces.
• Dismantling and moving items and furniture in confined spaces.
• Working on construction sites, industrial areas in confined spaces.
• Installing and repairing security systems, fire fighting systems in confined spaces.

d. Occupational safety card

After completing the occupational safety training course and passing the exam, the worker will be issued an occupational safety card (in practice, also called a Group 3 occupational safety certificate).

In which, the Group 3 safety card will clearly show information such as: full name, date of birth, job and specific work environment. At the same time, there will be the training duration, a red seal and a signature confirming the completion of the training course.

According to the regulations on issuing safety cards specified in clause 2 of article 24 of decree 44/2016/ND-CP, there are 2 cases:

• In case the employer and the employee have an employment contract with each other, the employer must sign, seal and initial the safety card for the trained person in Group 3 after undergoing the training course from the occupational safety training unit and passing the exam.
• In case of freelance, seasonal workers, without an employment contract, the training unit must sign, seal and initial the safety card for the worker after undergoing the training course from the occupational safety training unit and passing the exam.

3. Recognizing hazards in confined spaces

The work environment in a confined space has many different hazards, including:

• Confined spaces often lack oxygen and ventilation, posing a danger to the health of workers. The air in this space often contains a lot of toxic fumes, dust and pollutants.
• Some jobs in confined spaces can pose a fire and explosion hazard, such as working with flammable or explosive substances, or using electronic devices, mining lights, welding machines, mobile phones…
• Jobs in confined spaces often require moving in a small space, so the risk of collision and being punctured by foreign objects is very high.
• Work environments in confined spaces often have high or low humidity and temperature compared to the outside environment. This can cause health problems for workers, including fever, cold, headache, difficulty breathing, discomfort…
• Jobs in confined spaces are often associated with the effects of ultraviolet and X-rays, especially in the electronics, tobacco, security, and medical manufacturing industries.

4. Safety measures in confined spaces

When working in a confined space, ensuring safety is very important. Here are some safety measures to be implemented:

• Before entering a confined space, the person performing the work needs to carefully check the space, identify all possible dangers and prepare all necessary safety equipment and gear.
• For confined spaces that may have foul or toxic odors, the person performing the work needs to ensure ventilation and minimize the impact of toxic substances to the lowest possible level.
• The person performing the work needs to use full personal protective equipment such as safety glasses, masks, gloves, chemical-resistant clothing, anti-slip shoes, safety ropes, etc.
• When working in a confined space, the person performing the work needs to have a quick rescue plan and mechanism in case of an incident or accident.
• Avoid working in a confined space for too long and need to have breaks to ensure health and safety for yourself.
• The person performing the work needs to be fully trained and trained in occupational safety on the necessary skills and safety measures when working in a confined space.
• Periodically organize workplace environment monitoring in factories, collect and analyze harmful factors to workers, thereby adjusting to reduce the level of harm to prevent occupational diseases for them.

These safety measures will help minimize the risk of accidents and ensure the health of those working in confined spaces.

5. Types of accidents in confined spaces

The types of accidents when working in confined spaces can include:

• Confined spaces often have toxic gases accumulated and unable to escape. Toxic gases such as CO gas, H2S gas, CO2 gas, methane gas,… can cause poisoning and be life-threatening.
• Due to the possibility of flammable or explosive substances in confined spaces, and due to the use of equipment for working in confined spaces that can create sparks.
• Confined spaces are often construction works, construction sites, industrial parks, etc., and when performing construction, repair, and maintenance work, there is a risk of collapse, collision.
• When working in a confined space, there is a risk of injury from impact, falling objects, or being stuck in a narrow space.
• Confined spaces often have a slope and uneven surfaces, and when performing tasks in confined spaces, it can lead to loss of balance, slipping and causing accidents.
