Occupational safety training for gypsum production

1. Overview of Gypsum

a. What is Gypsum?

• Gypsum is a common building material made from hydrated calcium sulfate (CaSO4·2H2O). It is used to create false walls, ceilings, partitions, soundproof walls, etc.
• Gypsum has many advantages, including good fire resistance, flexibility in design and installation, high durability, and noise reduction capability. It is also easy to cut, drill, sand, and paint to suit specific design requirements.
• There are two main types of gypsum: regular gypsum and moisture-resistant gypsum. Regular gypsum is used in dry areas not exposed to water, while moisture-resistant gypsum is used in areas with higher humidity, such as bathrooms or kitchens.
• According to statistics from the Vietnam Construction Association, gypsum production in 2020 was estimated at about 15 million m2, an increase of 7% compared to the previous year. Gypsum manufacturing companies in Vietnam are growing and providing gypsum products with increasingly high quality and affordable prices, meeting the needs of the domestic and international markets.

b. Types of Gypsum Production Machinery

The types of machinery involved in gypsum production include:

• Crusher: Used to crush gypsum raw materials before feeding them into the kiln.
• Dryer: Used to dry gypsum particles after they have been ground.
• Mixer: Used to mix the gypsum compound with additives such as fiberglass, cellulose fibers, shaping agents, etc.
• Press: Used to press and shape the mixture of gypsum and additives into gypsum boards.
• Cutter: Used to cut gypsum boards into desired sizes and shapes.
• Grinder: Used to grind and pulverize cut gypsum boards into gypsum powder.
• Drill and Sander: Used to drill holes and sand gypsum surfaces for use in construction projects.
• Stacker: Used to stack gypsum boards into bags and cartons for transportation to a destination.

These machines are often used in gypsum factories to increase productivity and reduce production costs.

c. Gypsum Production Companies in Vietnam

In Vietnam, there are many gypsum production companies, including large enterprises such as:

• Knauf Group: Founded in 1932 in Germany, Knauf is one of the world’s largest gypsum producers. In Vietnam, Knauf established a gypsum factory in Phuc Dien Industrial Park, Long Bien, Hanoi in 2010.

b. Training Duration

Initial safety training duration

• The total training duration is at least 24 hours, including the test time.
• 8 hours of theoretical study on the system of policies and laws on labor safety and hygiene.
• 8 hours of theoretical study on basic knowledge of labor safety and hygiene.
• 4 hours of theoretical study on specialized training content.
• 2 hours of practical training on specialized training content.
• 2 hours of theoretical testing at the end of the training course.

The safety training center will distribute the time into several training sessions depending on the time arrangement for employees. But usually, there will be 6 training sessions, the course will take place over 3 days, provided that the manufacturing company can arrange continuous study time.

Periodic safety training duration

• Before the labor safety card expires, if workers want to have it reissued, they must undergo a periodic labor safety training course, with a periodic safety training duration of at least 50% of the initial safety training duration.

d. Labor Safety Card

After completing the labor safety training course and passing the test, the worker will be issued a labor safety card (in practice, it is often called a Group 3 labor safety certificate).

The group 3 safety card will clearly state information such as: full name, date of birth, specific job and working environment. It also includes the training time, red stamp, and 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 two cases:

• Case where the employer and the employee have a labor contract with each other, the employer must sign, stamp, and seal the safety card for the trained person in Group 3 after they have gone through the training course from a labor safety training unit and passed the test.
• Case where the worker is a freelancer, seasonal worker, and does not have a labor contract, the training unit must sign, stamp, and seal the safety card for the worker after they have gone through the training course from a labor safety training unit and passed the test.

3. Identifying Dangers Affecting Workers in Gypsum Production

The production of gypsum can pose many dangers that affect the health of workers. Below are some common dangers and how to identify them:

• When producing gypsum, gypsum boards are often ground or cut, resulting in the creation of gypsum dust. This dust can cause respiratory problems such as bronchitis, asthma, or lung cancer. How to identify: Gypsum dust is often white, light, and floats in the air. Workers can recognize gypsum dust by seeing or inhaling it.
• Machinery in a gypsum factory creates loud noise, causing hearing problems such as hearing loss or hearing damage. How to identify: Noise is often at a high level and can be heard clearly from a distance.
• During the gypsum production process, toxic gases such as SO2, CO2, NOx, CO, H2S… can be generated. These toxic gases can cause health problems such as headaches, nausea, or cardiovascular disease. How to identify: Toxic gases are often odorless or have an unpleasant odor and workers may feel uncomfortable, nauseous, or dizzy.
• Equipment in a gypsum factory can generate high voltage, posing a danger to workers. How to identify: High voltage is often displayed on the equipment, and workers may feel a tingling or shock when in contact with high voltage.

4. Types of Labor Accidents that Often Occur to Workers in Gypsum Production

The types of labor accidents that often occur to workers in gypsum production can include:

• Accidents due to machinery: Machinery in a gypsum factory can cause labor accidents such as crushing, cutting, collision, or being caught. These accidents can cause serious injury or death to workers.
