For how long must DPM sample results be retained?

The requirement for retaining DPM (Diesel Particulate Matter) sample results for a period of 5 years aligns with safety regulations and best practices in the mining industry. This duration ensures that records are available for review, enabling ongoing evaluation of air quality and employee exposure over a significant period. Retaining records for 5 years helps in identifying trends in air quality, assists in compliance with regulatory standards, and provides necessary documentation in the event of inspections or audits. It also allows for adequate assessment of the effectiveness of any interventions or modifications made to improve workplace conditions. Maintaining these records is an essential aspect of health and safety management within mining operations.
