Respirable Crystalline Silica Manchester

Hazardous Substance Assessment in Manchester

In February 2025, a Hazardous Substance Assessment was carried out at a construction site in Manchester to evaluate employee exposure to airborne contaminants, particularly dust and respirable crystalline silica (RCS). The focus was on operatives working in lift shaft areas, where drilling and anchoring activities generate airborne dust.

The results showed that all measured dust and silica levels were well below Workplace Exposure Limits (WELs), meaning exposure is controlled under current working conditions. The use of hollow drill bits with local exhaust ventilation (LEV) linked via Bluetooth to the drill played a key role in keeping dust levels low. However, care should still be taken when emptying or maintaining LEV vacuum systems to prevent unnecessary exposure.

To maintain safe conditions, the report recommended continuing the use of LEV systems, ensuring workers have access to respiratory protective equipment (RPE) and providing regular training on dust control measures. Additionally, routine air monitoring and health surveillance were advised to track any potential long-term risks.

By following these recommendations, the site can continue to protect workers from hazardous dust exposure, ensuring a safer and healthier working environment for all operatives.

Hazardous Substances Assessment at Manchester Lift Shaft

We recently carried out a hazardous substances assessment at a lift shaft project in Manchester. Our aim was to evaluate the exposure levels of workers to respirable crystalline silica and general dust. Using both personal and static air sampling methods, we gathered data on the concentration of these substances during typical work activities.

The findings showed that the levels of respirable crystalline silica and dust were within the safe limits set by workplace exposure regulations. However, due to the carcinogenic nature of silica, we recommended implementing a health surveillance programme for the operatives. The use of respiratory protective equipment (RPE) was also advised, although current controls appeared sufficient.

To further reduce risks, we suggested maintaining regular testing of the local exhaust ventilation (LEV) systems and ensuring proper training for all employees on dust suppression and the use of control measures. This project highlighted our commitment to ensuring a safe working environment by providing thorough assessments and practical safety recommendations.
