- Mitigating the high potential hazards in the Mineral Products Industry

Fatal 4 - Respirable Crystalline Silica 

Unlike the other Fatal 6, which relate primarily to trauma as a result of a single incident, the health and safety issues from respirable crystalline silica (RCS) arise from the long term  exposure to very small particles at concentrations  above the recommended levels.  The risks primarily arise when working in close proximity to the source.   

The long term effect of exposure to silica dust include silicosis, an incurable lung disease that leads to disability and death, lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease. Exposure to respirable crystalline silica is also related to the development of auto-immune disorders and cardiovascular impairment. 

Those most likely to be at risk are individuals involved in the mechanical sawing, grinding, polishing of concrete products or stone, particularly if the operation occurs within a confined space. 

The risks from exposure to RCS can be mitigated by the introduction of effective management controls, wearing appropriate PPE and the design of manufacturing systems that remove the dust from the atmosphere.

Typical measures include;

  • Establishing and implementing a written exposure control
  • Procedures to restrict access to areas  with high exposures  
  • Designating a competent person to implement plan
  • Use of appropriate RPE
  • Ensuring operators are trained in its use
  • Ensuring it is easily accessible and well fitted.
  • Use of housekeeping practices that minimise dust 
  • Engineering in dust suppression or removal
  • Medical examinations -including chest X-rays and lung function tests
  • Training workers  to raise their awareness of RCS 
  • Training workers to limit their exposure
  • Maintaining  records of exposure, objective data, and medical exams.

Respirable Crystalline Silica Monitoring Protocol - NePSi - June 2021

NePSi published an updated version of a Respirable Crystalline Silica Monitoring Protocol in June 2021

The main objective of this monitoring protocol is to provide a harmonized methodology to measure exposure to respirable crystalline silica (RCS) of workers employed at member companies of the NEPSI signatories. The project aims to provide a common basic methodology to help those sectors who do not have a standardized monitoring methodology in place and enable these sectors to collect RCS exposure data in a harmonized and representative way.

Guidance is provided on measurement strategy, appropriate sampling and analytical methods, and data management.

The implementation of the protocol is not mandatory, but should be considered as guidance for the development of a dust and quartz monitoring programme within all NEPSI partners.
