Occupational Safety Training for Automatic Foam Pouring Machine Operation

1. Overview of Automatic Foam Pouring Machines

a. What is an automatic foam pouring machine?

An automatic foam pouring machine is equipment used to automate the process of pouring polyurethane foam or other types of foam into molds or desired products. This equipment is commonly used in manufacturing industries to create foam products such as mattresses, pillows, or insulation components.

Benefits:

• High Efficiency: Increases productivity and reduces production time compared to manual methods.
• Consistent Quality: Ensures uniform product quality thanks to precision in mixing and pouring foam.
• Cost Savings: Reduces labor costs and minimizes material waste.

Applications:

• Mattress and Pillow Production: Pouring foam into molds to produce various types of mattresses and pillows.
• Insulation: Producing insulation components for the construction and automotive industries.
• Packaging: Providing protective packaging solutions for sensitive products.

The automatic foam pouring machine is an essential tool in the foam industry, helping to enhance production efficiency and improve product quality.

b. Operating principle of the automatic foam pouring machine

Material Preparation

• Chemical Materials: Automatic foam pouring machines use chemical components to produce polyurethane foam or other foams. The main components typically include isocyanate and polyol, along with additives such as foaming agents, stabilizers, and flame retardants.
• Material Storage: These materials are stored in separate containers connected to the machine via pipelines.

Mixing Materials

• Mixing System: The machine is equipped with an automatic mixing system to blend the chemical components at precise ratios. The system often includes agitators or mixers to ensure the components are evenly mixed.
• Ratio Control: The ratio between chemical components is adjusted via valves or metering pumps to achieve the desired foam quality.

Pumping and Pouring

• Material Pumping: After mixing, the foam mixture is pumped through pipelines to molds or desired shapes. The pumping system is typically adjusted to control the flow rate and pressure of the foam mixture.
• Foam Pouring: The machine may be equipped with flexible pouring heads to distribute the foam mixture into different molds or shapes. The pouring process can be adjusted to ensure even and precise foam distribution.

Temperature and Time Control

• Temperature Control: The temperature of the foam mixture and molds is often monitored and adjusted to ensure proper curing. The machine may have temperature sensors and cooling or heating systems to adjust the temperature.
• Curing Time: The time required for the foam to solidify can be automatically controlled, usually based on the technical specifications of each foam type. The machine may use timers or sensors to adjust curing time.

Finishing and Processing

• Cutting and Processing: After the foam has cured and meets quality requirements, the product can be cut or further processed to achieve the final size and shape. Some automatic foam pouring machines can integrate these steps into the process.
• Quality Inspection: The machine often has quality control systems to ensure the final product meets durability, uniformity, and other specifications.

c. Industries that use automatic foam pouring machines

b. Training duration

Initial safety training duration

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

The safety training center will schedule multiple training sessions depending on worker availability. Typically, there are 6 sessions over 3 days, provided the company can arrange continuous training time.

Periodic safety training duration

• Before the occupational safety card expires, workers who want to renew it must undergo periodic occupational safety training, with a duration equal to at least 50% of the initial safety training duration.

Explanation: The total periodic safety training duration is at least 12 hours, including testing time. After completing the periodic training and passing the test, workers will be reissued or have their occupational safety cards renewed.

c. Training content

See more training content for the 6 groups

d. Occupational safety card

After completing the occupational safety training course and passing the test, workers will be issued an occupational safety card (commonly known as a Group 3 safety certificate).

The Group 3 safety card specifies information such as full name, date of birth, job, and specific working environment. It also includes the training duration, official stamp, and signature confirming course completion.

According to the regulations on issuing safety cards stated in Clause 2 of Article 24 of Decree 44/2016/NĐ-CP, there are two cases:

• When the employer and employee have a labor contract, the employer must sign, stamp, and seal the safety card for the Group 3 trainee after they complete training from an occupational safety training provider and pass the test.
• In the case of freelancers or seasonal workers without a labor contract, the training unit must sign, stamp, and seal the safety card for the worker after they complete training from an occupational safety training provider and pass the test.

3. Hazards to workers when operating automatic foam pouring machines

Mechanical Hazards

• Being Pinched or Impacted: Moving parts of the machine, such as agitators and pumps, can cause the risk of being pinched or struck if not properly guarded.

Chemical Hazards

• Exposure to Chemicals: Chemicals used in foam production, such as isocyanates and polyols, can cause irritation to the skin, eyes, or respiratory tract if contacted directly.

Thermal Hazards

• High Temperatures: During production, temperatures can rise, especially in mixing and curing areas. High temperatures can cause burns or discomfort.

Electrical Hazards

• Electrical Malfunctions: Machinery may experience electrical faults, such as short circuits or leakage, posing the risk of electric shock.
