Occupational safety training for hollow brick production

1. Overview of Hollow Bricks

a. What are hollow bricks?

• Hollow bricks are a type of rectangular-shaped brick, made from lightweight concrete, clay, or fly ash (unburnt bricks), which can be used to build retaining walls, partition walls or structures requiring sound insulation and thermal insulation properties. They are manufactured in various ways, including firing with heat, high-pressure material compression, or concrete bonding. Hollow bricks are commonly used in civil and industrial construction projects.
• Currently, the hollow brick manufacturing industry in Vietnam is developing quite actively, meeting the needs of both domestic and international markets. Hollow brick manufacturing companies in Vietnam can be divided into two groups: large-scale manufacturers and small-scale manufacturers.
• The group of small-scale manufacturers includes private enterprises or cooperatives that produce hollow bricks. These businesses are often smaller in scale, use simpler technology, and produce basic types of hollow bricks.
• However, there are still some issues in the hollow brick manufacturing industry in Vietnam, such as: product quality differences, lack of investment in research and technology development, and inadequate labor safety.

b. Types of Hollow Brick Production Machinery

There are many types of machinery used in the hollow brick production process, depending on the technology and production scale of each company. However, the most basic machines for producing hollow bricks include:

• Pressing machine: Used to press a mixture of clay and other raw materials into the brick mold to create the desired shape and size.
• Cutting machine: Used to cut hollow bricks into fixed-length sections.
• Drying machine: Used to dry hollow bricks after pressing and cutting to ensure the product’s solidity and durability.
• Polishing machine: Used to polish the surface of hollow bricks to create a smooth and shiny finish for the product.
• Logo printing machine: Used to print logos, brand names, images, or other information on the surface of hollow bricks.

In addition, large-scale companies that use more modern technology also use other equipment and machinery such as grinding machines, mixers, measuring machines, processing machines, air compressors, steam compressors, steam generators, kilns, and product quality testing equipment.

c. Typical Hollow Brick Production Companies

Currently, there are many hollow brick manufacturing companies in Vietnam with different scales and product qualities. Here are some typical hollow brick production companies in Vietnam:

d. Specific Jobs in a Hollow Brick Production Factory

Group 1

• Executive director, deputy executive director, department head in a hollow brick production factory.

Group 2

• Safety officer: manages safety in the factory, designs safety procedures, and supervises and urges employees to comply with safe work procedures.

Group 3

• Raw material preparation: This is a crucial step to produce quality hollow bricks. The main raw materials include clay, kaolin clay, spongy clay, various additives, and water.
• Raw material mixing: The raw materials are put into mixers to be evenly mixed. The mixing process must ensure the correct ratio and quality of materials to ensure the quality of the hollow bricks.
• Pressing into hollow shapes: The raw materials are pressed into hollow shapes using specialized pressing machines. Typically, the output of the pressing machine is long, tapered, or square-shaped hollows.
• Drying: After being pressed into hollow shapes, the bricks need to be dried. The drying process usually uses a drying kiln, where the bricks are placed on racks and dried for a certain period.
• Firing: The firing process is the final step to create the finished hollow brick product. The bricks are put into a kiln and fired at a high temperature for a certain period. After this process, the bricks will have a certain color and hardness.
• Transportation and stacking in the warehouse: After the finished brick products are ready, they will be taken to the warehouse, or transported from the warehouse to stores and construction sites.

Group 4

• Office jobs, serving, sales, marketing.
• Production management, quality management, human resource management, material management, financial accounting management.

2. Overview of the Hollow Brick Production Labor Safety Training Course

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 normally, 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.

Explanation: The total periodic labor safety training duration is at least 12 hours, including the test time. After completing the periodic training course and passing the test, the worker will be re-issued or have their labor safety card renewed.

c. Content of the training course

See more training content for 6 groups

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 show information such as: full name, date of birth, specific job and working environment. It also includes the training duration, 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.
