Key Regulations and Standards for Occupational Noise Measurement in the Workplace
Unacceptable noise can be defined as any unwanted, annoying, or potentially harmful sound that poses significant risks to workers, particularly in industrial environments. Prolonged exposure to these levels at or above 85db(A) can lead to noise-induced hearing loss (NIHL), a serious occupational health condition. Therefore, understanding and complying with regulations and standards for occupational noise measurement are vital for ensuring worker safety.
Allow the experts at IOH Solutions to explain the importance of noise measurement in the workplace and how it can assist you in protecting your workforce.
Regulatory Framework of Occupational Noise Measurement
In South Africa, the Occupational Health and Safety Act, No. 85 of 1993, plays an important role in addressing occupational noise hazards, specifically, the NIHL regulations. Under this Act, stringent measures are in place to protect workers from the many effects of excessive noise. These are designed to limit noise exposure, ensuring businesses adopt appropriate noise control measures.
Key Compliance Requirements
- Noise Measurement: The first step in compliance is accurate noise measurement. Companies must conduct regular noise assessments to determine noise levels in the workplace. This includes using calibrated sound level meters to record noise levels across different areas and during various operations.
- Noise Surveys: Comprehensive noise surveys are required to identify noise sources and assess potential risks. These surveys should be conducted by qualified professionals who can interpret the data and recommend appropriate control measures.
- Control Measures: Based on the results of these measurements and surveys, companies must implement noise control measures. These may include engineering controls like machinery upgrades, administrative controls, such as job rotation to limit exposure, and personal protective equipment (PPE) like earplugs or earmuffs.
- Hearing Conservation Practices: Businesses should establish hearing conservation programmes that include regular hearing tests, noise exposure monitoring, and medical surveillance to detect any early signs of hearing loss.
- Information Sharing: Workers must be informed of the risks associated with noise exposure and the proper use of PPE. Regular information-sharing sessions help maintain awareness and ensure compliance with noise control practices.
- Record Keeping: Maintaining detailed records of noise measurements, implemented control measures, information sharing, and medical surveillance is essential. These records serve as proof of compliance and can be vital during audits and inspections.
Industry Standards
Along with regulatory requirements, companies should adhere to industry standards that provide guidelines for best practices in occupational noise measurement. These standards are often set by organisations like the International Organisation for Standardisation (ISO). Compliance with these standards ensures that noise management and control practices meet both local and international benchmarks.
