Occupational environment monitoring at a PVC pipe manufacturing factory

1. Overview of PVC Pipe Manufacturing Factory

a. What is a PVC pipe manufacturing factory?

Factory producing PVC pipes is a manufacturing facility specializing in the production of pipes made from PVC (Polyvinyl Chloride). PVC is a widely used synthetic plastic in the pipe industry due to its moisture resistance and chemical resistance.

b. Production stages in the PVC pipe manufacturing factory

The main stages in the PVC pipe manufacturing process may include:

• Raw material preparation:
  • PVC Resin: The main material for making PVC pipes.
  • Additives: Including stabilizers, flame retardants, enhancers, colorants, and other additives to improve the physical and chemical properties of the pipes.
• Mixing:
  • PVC resin and additives are mixed in a mixer to form a homogeneous PVC compound.
  • This process ensures uniform distribution of components and achieves a high level of mixture consistency.
• Pipe extrusion:
  • The PVC compound is fed into an extrusion machine.
  • During this process, the PVC compound is melted and pushed through a mold to form PVC pipes of the desired shape and size.
• Cooling and cutting:
  • After extrusion, the hot PVC pipe is cooled with water or air to achieve final rigidity and shape.
  • After cooling, the pipe is cut into sections of the required length.
• Quality control:
  • Cut pipe sections are checked for compliance with standards on dimensions, strength, and quality.
  • Quality inspection may include measuring diameter, opacity, strength, elasticity, and leakage testing.
• Packing and warehousing:
  • PVC pipes passing quality checks are packed according to factory standards.
  • Then, they are transported to users or distributors.

c. Machinery used in PVC pipe manufacturing factory

In a PVC pipe factory, several types of machinery are used in the production process. Common equipment includes:

• Mixer: Used to mix PVC resin and additives to create a uniform compound.
• Pipe extruder: Used to melt the PVC mixture and push it through a mold to form pipes of desired shape and size.
• Cooling machine: Used to cool pipes after extrusion to achieve final rigidity and shape.
• Pipe cutter: Used to cut pipes into required lengths after cooling.
• Quality control machine: Used to check parameters such as diameter, strength, opacity, and elasticity.
• Packing machine: Used to pack pipes after quality inspection according to factory standards.

d. Occupational diseases workers may face in PVC pipe factories

Workers in PVC pipe factories may be exposed to environmental and production hazards, causing some occupational diseases. Common ones include:

• Respiratory diseases: Exposure to hot PVC fumes and additives may irritate the respiratory system, causing coughing, shortness of breath, or pneumonia.
• Skin allergies: Exposure to chemical compounds may cause skin irritation, itching, dermatitis, or other skin issues.
• Eye problems: Dust, chemical fumes, and irritants can cause conjunctivitis, eye irritation, or vision issues.
• Joint and musculoskeletal issues: High-intensity tasks such as lifting, moving, and assembling parts can cause joint injuries, arthritis, and musculoskeletal problems.
• Lead poisoning: Certain PVC compounds contain lead, long-term exposure may affect the nervous system, digestive system, and blood formation.

e. Common types of PVC pipes on the market

There are many types of PVC pipes depending on their use and specifications. Common ones include:

• Water supply PVC pipes: Used for transporting drinking, industrial, and wastewater, with varying diameters and thicknesses.
• Drainage PVC pipes: Used to drain water from plumbing or rainwater systems, with larger diameters and higher pressure tolerance.
• Distribution PVC pipes: Used in public water systems or large buildings, designed to withstand high pressure and long lifespan.
• PVC pipes for air-conditioning systems: Used to transport air in HVAC systems for buildings, homes, and offices.
• PVC pipes for gas systems: Used to transport gases, hot steam, or cold air in industrial systems.

2. Overview of Occupational Environment Monitoring Services

a. What is occupational environment monitoring in PVC pipe factories?

Occupational environment monitoring in PVC pipe factories involves collecting, evaluating, and analyzing environmental indicators to take timely measures to reduce harmful effects on workers’ health and prevent occupational diseases. Monitoring is legally required for PVC pipe factories.

Monitoring is crucial for protecting and enhancing workers’ health because employees are the core resource generating profits for the business. Prolonged exposure to hazardous factors beyond permissible limits may harm health and cause occupational diseases.

d. PVC pipe factory monitoring report

Reports are prepared according to Form 04, Appendix III of Decree 44/2016/ND-CP in two copies: one for the contracting workplace and one for the monitoring organization. Records are kept indefinitely.

e. Frequency of occupational environment monitoring

According to Clause 2, Article 18, Law on Occupational Safety and Hygiene 84/2015/QH13, employers must perform monitoring at least once a year.

f. Deadline for submitting monitoring reports

Reports must be submitted before December 31 each year to the Department of Health where the business is headquartered and where employees work. Updates are required when production processes or facilities change, potentially introducing new hazards.

g. Penalties for violations of occupational environment monitoring regulations

According to Article 27 of Decree 12/2022/ND-CP, employers face penalties:

• Clause 2: 2,000,000 – 5,000,000 VND if monitoring results are not disclosed to workers promptly.
• Clause 3: 20,000,000 – 40,000,000 VND for failing to perform required monitoring.
• Clause 4: 40,000,000 – 60,000,000 VND for colluding with monitoring organizations to falsify data without reaching criminal liability.

3. Harmful Environmental Factors for Workers in PVC Pipe Manufacturing Factories

Workers in PVC pipe manufacturing factories may be exposed to several harmful environmental factors, including:

• Chemicals: The PVC pipe production process may involve the use of chemicals such as colorants, fragrances, stabilizers, and other additives. Exposure to these chemicals can cause skin, eye, and respiratory irritation and pose health risks.
• Dust and fine particles: During the processing and manufacturing of PVC pipes, dust and fine particles can be generated from cutting, grinding, and machining processes. Inhalation of these fine particles and dust can cause respiratory irritation, difficulty breathing, and potential respiratory issues.
• Noise: Machinery and equipment in PVC pipe manufacturing factories can generate high levels of noise. Prolonged exposure to noise can cause sleep disturbances, stress, and hearing-related problems.
• Temperature and humidity: Some PVC pipe production processes can produce high temperatures or humidity. Working in environments with excessive heat or moisture can challenge workers, affecting health and work performance.
• Waste materials and emissions: PVC pipe factories may generate waste materials such as scrap, residues, and emissions from the production process. Proper management and disposal of waste are necessary to ensure a safe working environment and protect the external environment.
