Introduction

In today’s global apparel supply chain, industrial hygiene and occupational health & safety (OHS) have become essential pillars of sustainable manufacturing. Factories that maintain clean indoor air, controlled exposure limits, and ergonomic working conditions consistently achieve higher productivity, better product quality, and improved worker retention.

This case study presents an Industrial Hygiene Survey and Indoor Air Quality Assessment conducted at a leading RMG facility in Bangladesh by Greentech Inspection Ltd.

About the Study

The assessment was performed to evaluate:

• Indoor air quality parameters
• Exposure levels of airborne pollutants
• Worker lung function (FEV1 testing)
• Compliance with WHO, OSHA, DOE, and EPA standards
• Ventilation effectiveness and workplace safety conditions

Monitoring was conducted across multiple production sections including cutting, sewing, printing, knitting, elastic dyeing, and finishing units.

Key Industrial Hygiene Parameters Monitored

The following pollutants and environmental factors were analyzed:

• Carbon Dioxide (CO₂)
• Carbon Monoxide (CO)
• PM2.5 & PM10
• Suspended Particulate Matter (SPM)
• Formaldehyde (CH₂O)
• Volatile Organic Compounds (VOCs)
• Ozone (O₃)
• Manganese (Mn)
• Temperature, Humidity & Air Velocity

Major Findings

1. Indoor Air Quality Performance

All measured pollutant levels were found within permissible limits set by DOE (Bangladesh), WHO, and EPA standards.

• CO₂ level: ~380 ppm (Good ventilation condition)
• PM10: 120 µg/m³ (Within limit)
• PM2.5: 65 µg/m³ (At permissible threshold)
• VOCs: 465 µg/m³ (Controlled exposure)
• CO: 760 µg/m³ (Excellent condition)

👉 Overall result: Healthy indoor environment with effective ventilation systems

2. Workplace Environment Conditions

• Average temperature: 29.4°C
• Relative humidity: 58.2%
• Air velocity: 0.05 m/s

The study confirmed that the factory has:

• Adequate natural ventilation
• Exhaust fan-supported air circulation
• No significant pollutant stagnation

3. Worker Health Indicator (FEV1 Test)

Forced Expiratory Volume (FEV1) tests were conducted to evaluate lung function:

• Male workers: slight average decline (~7.8 cm³)
• Female workers: slight average decline (~5.8 cm³)

👉 Interpretation:
No significant respiratory impairment was observed, indicating low occupational exposure risk under current conditions.

4. Exposure Limit Compliance (TWA & STEL)

The study compared:

• 8-hour Time Weighted Average (TWA)
• Short Term Exposure Limit (STEL – 15/30 min)

Findings:

• All values were below OSHA, WHO, and DOE limits
• No Immediately Dangerous to Life or Health (IDLH) conditions detected

Discussion

The results confirm that the assessed garment factory demonstrates:

• Strong occupational health and safety practices
• Effective ventilation and emission control systems
• Low risk of long-term respiratory exposure
• Compliance with international environmental standards

This reflects how modern RMG factories in Bangladesh are improving industrial hygiene practices, aligning with global sustainability and ESG expectations.

Importance for Bangladesh RMG Industry

The apparel sector in Bangladesh contributes significantly to national GDP and export earnings. However, sustainable growth depends on:

• Safe working environments
• Pollution control systems
• Continuous industrial hygiene monitoring
• Regulatory compliance with DOE, WHO, OSHA standards

Factories adopting such practices are more likely to attract international buyers and long-term partnerships.

Conclusion

The Industrial Hygiene Assessment conducted by Greentech Inspection Ltd at Apex Fashion Wear Limited confirms a well-managed indoor environment with pollutant levels within safe limits.

Overall, the facility demonstrates:

• Safe occupational exposure levels
• Effective air quality management
• Good worker health indicators
• Compliance with global safety standards

This case study highlights that healthy workplaces lead to sustainable productivity and higher-quality garment production in Bangladesh’s RMG sector.
