Mining operations present some of the most complex occupational health hazards in Canada. Western Health & Safety provides CIH-led mining occupational hygiene services including exposure assessments, silica monitoring, diesel particulate monitoring, noise assessments, ventilation evaluations, and occupational exposure monitoring programs for underground and surface mining operations. We support mining companies, contractors, engineering firms, and project teams with practical exposure assessment strategies designed to protect worker health, meet regulatory requirements, and support operational performance.
Occupational Hygiene Challenges in Mining
Mining environments can expose workers to a wide range of occupational health hazards that require ongoing assessment, monitoring, and control. Underground and surface mining operations often involve exposure to airborne contaminants, excessive noise, diesel emissions, heat stress, vibration, and other workplace hazards that can affect worker health over time. Effective occupational hygiene programs help mining companies identify risks, evaluate worker exposures, and implement practical control measures to reduce health impacts and maintain regulatory compliance.
One of the most significant concerns in mining is exposure to respirable crystalline silica generated during drilling, blasting, crushing, and material handling activities. Diesel particulate matter (DPM) from mobile equipment can also present significant risks, particularly in underground mining environments where ventilation is critical. In addition, workers may be exposed to elevated noise levels, welding fumes, metal particulates, naturally occurring radioactive materials (NORM), and other chemical and physical hazards depending on the mining process.
A comprehensive mining occupational hygiene program combines exposure monitoring, ventilation assessments, worker exposure evaluations, and exposure control planning to support a safer and healthier workplace. Western Health & Safety provides CIH-led occupational hygiene consulting services to help mining companies understand workplace exposures, prioritize risks, and develop practical solutions that protect workers while supporting operational objectives.
Mining Exposure Assessment Services
Effective occupational hygiene programs begin with understanding worker exposures. Western Health & Safety provides comprehensive mining exposure assessment services for underground and surface mining operations across Canada. Our assessments are designed to identify workplace health hazards, quantify worker exposures, and support informed decisions regarding exposure controls, regulatory compliance, and worker health protection.
Our mining exposure assessment programs evaluate a wide range of occupational hazards, including respirable crystalline silica, diesel particulate matter (DPM), airborne dust, welding fumes, metals, noise, heat stress, vibration, and other chemical and physical agents. Exposure monitoring is conducted using recognized occupational hygiene methods and industry best practices to ensure accurate and defensible results.
Exposure assessments may include personal exposure monitoring, area sampling, task-based assessments, ventilation evaluations, and worker exposure profiling. The information collected helps mining companies understand exposure trends, identify high-risk activities, evaluate the effectiveness of existing controls, and prioritize corrective actions where required.
Western Health & Safety works closely with mine operators, contractors, engineering teams, and health and safety personnel to develop practical exposure assessment programs tailored to the specific conditions of each operation. Our goal is to provide actionable data that supports worker protection, operational efficiency, and compliance with applicable occupational health and safety requirements.
Silica Exposure Monitoring for Mines
Respirable crystalline silica is one of the most significant occupational health hazards in the mining industry. Activities such as drilling, blasting, crushing, screening, conveying, and material handling can generate airborne silica dust that may be inhaled by workers. Prolonged exposure to respirable crystalline silica has been associated with serious health effects including silicosis, chronic obstructive pulmonary disease (COPD), lung cancer, and other respiratory illnesses.
Western Health & Safety provides CIH-led silica exposure monitoring programs for underground and surface mining operations across Canada. Our occupational hygiene assessments are designed to evaluate worker exposure levels, identify high-risk tasks, and support effective exposure control strategies. Monitoring programs may include personal air sampling, task-based exposure assessments, area monitoring, and evaluation of engineering and administrative controls.
Silica exposure assessments help mining companies understand where exposures occur, which workers are most at risk, and whether existing control measures are effectively reducing airborne dust concentrations. The results can be used to support regulatory compliance, worker health protection initiatives, exposure control planning, and continuous improvement of occupational hygiene programs.
Our consultants work with mine operators, contractors, and health and safety teams to develop practical silica management strategies that align with operational requirements while protecting worker health. By identifying exposure sources and implementing effective controls, mining organizations can reduce long-term health risks and create safer working environments.

Diesel Particulate Monitoring for Underground Mines
Diesel-powered equipment remains essential to many mining operations, particularly in underground environments where loaders, haul trucks, utility vehicles, and other mobile equipment are used daily. The operation of diesel engines can generate diesel particulate matter (DPM), a complex mixture of airborne particles and gases that may pose occupational health risks when workers are exposed over extended periods.
Western Health & Safety provides CIH-led diesel particulate monitoring services for underground and surface mining operations across Canada. Our occupational hygiene assessments help mining companies evaluate worker exposures, identify areas of concern, and assess the effectiveness of ventilation systems and exposure control measures. Monitoring programs are designed to provide reliable exposure data that supports worker health protection and occupational hygiene program development.
Diesel particulate monitoring may include personal exposure sampling, area monitoring, task-based assessments, and evaluations of work activities that contribute to elevated exposures. Results can be used to identify high-risk occupations, prioritize control measures, and support ongoing occupational health and safety initiatives.
In underground mining environments, diesel particulate monitoring is often closely linked to mine ventilation performance. Understanding both worker exposures and ventilation effectiveness provides valuable information for managing airborne contaminants and reducing occupational health risks. By combining exposure monitoring with practical recommendations, Western Health & Safety helps mining organizations develop effective strategies to control diesel particulate exposures and improve workplace air quality.

Noise Assessments for Mining Operations
Noise exposure is a common occupational health concern in both underground and surface mining environments. Drilling equipment, crushers, conveyors, mobile equipment, processing facilities, ventilation systems, and other mining activities can generate elevated noise levels that may contribute to noise-induced hearing loss if exposures are not properly assessed and managed.
Western Health & Safety provides CIH-led noise assessment services for mining operations across Canada. Our occupational hygiene assessments help mining companies evaluate worker noise exposures, identify high-noise tasks and work areas, and support the development of effective hearing conservation and noise control programs. Monitoring programs are designed to provide accurate exposure data that can be used to assess workplace risks and prioritize control measures.
Noise assessments may include personal noise dosimetry, area noise surveys, task-based exposure evaluations, and workplace noise mapping. These assessments help determine which workers are exposed to elevated noise levels, identify significant noise sources, and evaluate the effectiveness of existing engineering, administrative, and personal protective controls.
Understanding worker noise exposure is an important component of a comprehensive mining occupational hygiene program. By identifying exposure trends and implementing practical noise reduction strategies, mining organizations can better protect worker hearing, improve workplace conditions, and support long-term occupational health objectives.

Mine Ventilation and Air Quality and Radiation Assessments
Effective mine ventilation systems play a critical role in controlling airborne contaminants and protecting worker health. Ventilation programs are designed to dilute and remove airborne hazards generated by mining activities, including respirable dust, diesel particulate matter (DPM), blasting by-products, welding fumes, and other airborne contaminants. Evaluating ventilation effectiveness is an important component of a comprehensive occupational hygiene program and helps mining organizations identify areas where additional controls may be required.
