Factory Noise Complaint Guide - Pollution Control Thailand
How to file complaints about factory noise in Thailand. Pollution Control Department, industrial noise standards.
Factory and industrial noise affects communities across Thailand, particularly near industrial estates and manufacturing zones. The sound of machinery, compressors, cooling systems, and production processes operating around the clock can severely impact the health and quality of life of nearby residents.
Industrial noise in Thailand is regulated by the Factory Act B.E. 2535 and the Ministerial Regulation on Noise Standards from the Department of Industrial Works. Factories must comply with the Pollution Control Department's ambient noise standards: no more than 70 dB(A) during the day and 50 dB(A) at night in residential zones. Factory internal noise must also comply with occupational health standards.
Communities affected by factory noise have the right to file formal complaints with both the Pollution Control Department (กรมควบคุมมลพิษ) and the Department of Industrial Works (กรมโรงงานอุตสาหกรรม). Both agencies have the authority to conduct on-site inspections, order compliance, and revoke operating licences for persistent offenders.
How to Complain About Factory or Industrial Noise
- 1. Document impact: Record noise occurrences with timestamps and decibel readings. Note how the noise affects sleep, work, and daily life.
- 2. Identify the factory: Note the factory name, address, and any visible licence or registration numbers.
- 3. File with the Pollution Control Department: Call PCD hotline 1650 or submit a written complaint. PCD can conduct ambient noise measurements and order the factory to comply.
- 4. File with the Department of Industrial Works: Contact กรมโรงงานอุตสาหกรรม, which has authority to inspect factories and impose conditions on operating licences.
- 5. Organise community action: Factory noise complaints are more effective when filed collectively. Coordinate with neighbours to submit a joint complaint.
Health Impacts of Industrial Noise
Prolonged exposure to factory noise above 55 dB(A) at night is associated with sleep disturbance, increased risk of cardiovascular disease, elevated stress hormones, and reduced cognitive performance. These health impacts are well documented in WHO guidelines and Thai public health research.
If you can demonstrate that factory noise is causing health harm, your complaint carries greater legal weight. A medical certificate documenting noise-related health effects, combined with acoustic evidence, can support a civil damages claim or an application to revoke the factory's operating licence.
