What You'll Learn
Silica is a contaminant and an irritant
The health risks associated with silica exposure are well-documented. Inhalation of RCS can cause silicosis, a disease that scars lung tissue and increases the risk of tuberculosis, lung cancer, and chronic bronchitis. Other potential health consequences include chronic obstructive pulmonary disease and kidney disease. The Occupational Safety and Health Administration (OSHA) estimates that over 34,000 foundry workers in the US are currently exposed to RCS.
Industries where silica exposure is prevalent include construction, tunnel work, masonry, sandblasting, glass manufacturing, stone cutting, and steel production. Even highway construction can expose nearby residents to silica particles. One notable example of silica air pollution was the World Trade Center collapse, which resulted in toxic air that affected first responders, clean-up crews, and citizens in the area.
To mitigate the risks associated with silica exposure, monitoring and control measures are essential. Personal and area dust monitoring equipment can help limit exposure, and real-time aerosol monitoring instruments can measure aerosol concentration. In addition, innovative dust abatement systems can be implemented to reduce dust emissions.
Due to the health hazards posed by silica exposure, it is considered a pollutant and is addressed in pollution liability policies. The Contractors Pollution Liability (CPL) policy, for example, provides coverage for bodily injury, property damage, defence, and cleanup related to silica exposure. The Pollution Legal Liability (PLL) policy also addresses silica as a pollutant, offering coverage for similar issues.

Industries that expose workers to silica
Silica, or more specifically respirable crystalline silica (RCS), is a common mineral found in the earth's crust. It is present in materials like sand, stone, concrete, and mortar. RCS is created when silica-containing rocks and minerals are blasted, chipped, cut, ground, and drilled, releasing small particles into the air that can be inhaled and settle in the lungs. Inhaling RCS can lead to serious health issues, including silicosis, lung cancer, chronic obstructive pulmonary disease, and kidney disease. Due to the dangers associated with silica exposure, it is crucial to identify industries that put workers at risk.
One of the industries where workers are vulnerable to RCS exposure is the metal foundries industry. The casting sand, fettlings, and kiln linings used in metal foundries can release RCS particles, endangering workers' health. The U.S. Occupational Safety and Health Administration (OSHA) estimates that 34,591 foundry workers are currently exposed to RCS.
Another industry where silica exposure is prevalent is the construction sector, particularly involving asphalt roofing materials, concrete products, cut stone, and clay products. Workers in the railroad, shipyard, and oil and gas industries, who often work with these materials, are at risk of inhaling RCS. Even those in dental laboratories and jewelry manufacturing are exposed to RCS due to the nature of their work.
Additionally, stone countertop fabrication and installation pose significant risks of silica exposure. Cutting, sawing, grinding, drilling, and crushing stone, rock, concrete, brick, block, and mortar generate RCS particles, which, if inhaled, can cause deadly lung diseases. This has prompted OSHA to implement initiatives to protect workers in this industry from silica exposure.
It is important to note that silica exposure is not limited to these industries alone. Any workplace where silica-containing materials are blasted, chipped, cut, ground, or drilled can potentially expose workers to RCS. Therefore, it is crucial for employers and workers to be vigilant about monitoring silica dust levels and implementing necessary safety measures to minimize exposure and protect workers' health.

Health risks of silica exposure
Silica exposure is a serious health risk, and even deadly in some cases. The mineral is commonly found in the earth's crust, and when rocks and minerals containing silica are disturbed, small particles are released into the air, which can be breathed in.
The health risks of silica exposure are well documented. Inhaling respirable crystalline silica (RCS) can lead to silicosis, an irreversible scarring and stiffening of the lungs. This condition typically occurs after 15-20 years of exposure to RCS, and symptoms include shortness of breath, fatigue, chest pain, and respiratory failure. In rarer cases, individuals exposed to high concentrations of RCS can develop symptoms within weeks, including fever and weight loss.
The dangers of silica exposure don't end with silicosis. Lung cancer, chronic obstructive pulmonary disease, and kidney disease have all been linked to RCS exposure. The tiny particles of silica cause scarring and inflammation, leading to the formation of lung nodules, which may indicate cancer. The scarring can also cause pulmonary fibrosis, making it difficult to breathe.
In addition to these serious health issues, silica exposure increases the risk of bacterial infections, such as tuberculosis. The respiratory system is particularly vulnerable to silica dust, but the damage doesn't stop there. The particles can also settle in other parts of the body, causing further issues.
The hazards of silica exposure are not limited to any one industry. While mining is often associated with silica-related health risks, workers in glass and steel factories, construction, and even dental laboratories and jewelry manufacturing are also at risk. It is important for employers and employees to be aware of the dangers and take steps to limit exposure, through monitoring and risk management processes.

Lawsuits and insurance liability
Silica is a pollutant and exposure to it can be deadly. Inhalation of respirable crystalline silica (RCS) can lead to silicosis, lung cancer, chronic obstructive pulmonary disease, and kidney disease. In 2003, the peer-reviewed journal Occupational & Environmental Medicine (OEM) published an article that closely linked RCS overexposure and COPD. The US Occupational Safety and Health Administration (OSHA) estimates that 34,591 foundry workers are currently exposed to RCS.
Workers in a variety of industries are exposed to RCS, including those in metal foundries, railroad, shipyard, oil and gas, dental laboratories, and jewelry manufacturing. In California, over 20 silicosis lawsuits have been filed, with attorney Raphael Metzger of Metzger Law Group at the forefront of these cases. Most silica-related lawsuits are product liability cases, with plaintiffs alleging negligence, negligent design or manufacture, and negligent failure to warn.
In terms of insurance liability, silica is considered a pollutant, and the environmental insurance marketplace does not limit coverage for silica under basic contractors pollution liability (CPL) and pollution legal liability (PLL). The CPL policy is available to all types of contractors and provides coverage for bodily injury, property damage, defense, and cleanup. The capacity available for CPL in the current marketplace exceeds $300 million, with the most any one insurer can offer being $150 million.
The PLL policy is offered to any organization that owns, leases, rents, acquires, or divests real estate or property. Like the CPL, it provides coverage for bodily injury, property damage, defense, and cleanup related to pollution conditions. The PLL is provided with a claims-made insuring agreement and can include coverage for mold or microbial matter, as well as bodily injury, property damage, and/or mold cleanup costs.
In the case of Pauli Systems v. Golden Eagle, the court held in favor of the insurance company, stating that silica dust falls within the broad definition of "any solid, liquid, gaseous, or thermal irritant or contaminant" and is identified by federal regulations as an air contaminant. This decision grants the insurance policy and its endorsements the meaning reasonably intended by the insurer and understandable by a reasonable insured.
For those considering a silica-related lawsuit, there are a couple of options. Firstly, a workers' compensation claim can be filed against the employer, which typically covers on-the-job injuries and occupational diseases. Secondly, a product liability claim or lawsuit can be filed against third parties such as job site owners and product manufacturers. It is recommended to hire an experienced product liability lawyer for such cases.

Monitoring and reducing silica exposure
Silica dust is a well-known health and environmental hazard. Exposure to silica dust, or respirable crystalline silica (RCS), can lead to silicosis, lung cancer, chronic obstructive pulmonary disease, and kidney disease. The danger arises when silica-containing rocks and minerals are blasted, chipped, cut, ground, and drilled, releasing small particles into the air that can be inhaled and settle in the lungs. As a result, monitoring and reducing silica exposure are crucial to protect workers and the public from the harmful effects of silica dust.
Monitoring Silica Exposure
Monitoring silica exposure is essential to ensure the health and safety of workers and to comply with work health and safety laws. There are several methods available to monitor and assess silica exposure:
- Total Dust Sampling: Collecting a total dust sample and sending it to a laboratory for analysis, typically using X-ray diffraction (XRD) techniques. OSHA provides guidance on collecting air samples to measure airborne silica.
- Personal and Area Dust Monitoring: Using personal and area dust monitoring equipment, such as real-time aerosol monitoring instruments, to measure aerosol concentration and identify unsafe particulate levels.
- Fixed Particulate Detection: Utilizing instruments that employ nephelometer technology to provide real-time particulate monitoring for site remediation or perimeter monitoring. These monitors measure the concentration of airborne particles and are essential for protecting workers.
- End-of-shift Silica Monitoring: Using specialized equipment, such as the NIOSH Pocket Guide to Chemical Hazards, to assess silica exposure at the end of a worker's shift.
Reducing Silica Exposure
In addition to monitoring, it is crucial to implement measures to reduce silica exposure and protect workers:
- Engineering Controls: Engineering controls are interventions that help eliminate or reduce exposure to hazards. Wet methods, such as water sprays and ventilation controls, are effective in controlling dust. Local exhaust ventilation should be used in dusty work areas, and water and ventilation controls can be combined for enhanced dust control.
- Work Practices: Safe work practices should be followed, such as using enclosures to isolate dusty work processes and avoiding dry sweeping or using compressed air during housekeeping.
- Personal Protective Equipment (PPE): Providing workers with appropriate PPE, such as respirators, to reduce their exposure to silica dust.
- Health Monitoring: Conducting regular health monitoring for workers exposed to silica, as outlined by organizations like Safe Work Australia, to detect any loss in lung function before permanent damage occurs.
By implementing effective monitoring techniques and following guidelines to reduce silica exposure, employers can protect their workers' health and ensure compliance with health and safety regulations.
