2. Hazards Identification


The finished Caesarstone® is an inert, stable product that does not release hazardous materials in its fully intact form. However, dust derived from Fabrication Processes* contains respirable crystalline silica (SiO2). Hence, workers involved in Fabricating Processes, whether at the fabrication workshop or upon installing and removing/demolishing Caesarstone® slabs are at risk for significant respirable crystalline silica exposure. During the Fabricating Process, it is necessary to consider the following information.  

* “Fabrication Process/es” or “Fabricating” or “Fabrication” means cutting, grinding, chipping, sanding, drilling, polishing, etc. manufacturing processes, including during installation or removal of the product.

In this SDS Caesarstone® slabs are referred to also as “products”.

CALIFORNIA PROPOSITION 65


WARNING: This product contains chemicals, including silica and titanium dioxide, that become airborne and respirable when fabricating the product and are classified by the State of California as causing cancer and birth defects. For information see www.p65warnings.ca.gov.

Potential Health Effects

Inhalation: Do not breathe dust.

Workers who inhale very small crystalline silica particles are at risk for silicosis – an incurable, progressively disabling and sometimes fatal lung disease. Silicosis results in permanent lung damage. Silica dust particles become trapped in lung tissue, causing inflammation and scarring and reducing the lungs’ ability to take in oxygen. Symptoms of silicosis can include shortness of breath, cough and fatigue, and may or may not be obviously attributable to silica. According to the USA OSHA alert of Feb 2015, workers exposed to airborne crystalline silica also are at increased risk for lung cancer, chronic obstructive pulmonary disease (COPD) and kidney disease, and according to certain medical schools of thought, such workers are also at increased risk for auto-immune diseases (for example rheumatoid arthritis).

Skin and Eye Contact: Mineral dust may produce transitory mechanical irritation to skin and eyes.

Aggravation of Pre-existing Conditions: Persons with impaired respiratory function and chronic respiratory disorders may be more susceptible to the effects of this substance and may be adversely affected by any airborne particulate matter exposure. Smoking can increase the risk of lung injury. Inhalation may increase the progression of tuberculosis.  Persons with preexisting skin disorders may be more susceptible to the effects of this material.

Employers should consult with a trained occupational safety and health professional in order to monitor the air in their workplace and in order to determine worker exposures to hazardous dust.

Exposure Control

Manufacturing and Installation: Dust derived from the Fabrication Processes contains crystalline silica (SiO2). Exposure to SiO2 dust without the use of suitable protection may cause serious diseases as detailed in Section 2 and Section 11.

 

Exposure to dust may be monitored and controlled with suitable control measures such as:

Engineering Controls: CNC machines and wet cutting methods are recommended to reduce generation of dust. When Fabricating the product, installing or removing/demolishing the installed product, use equipment with integral dust collection and/or use local exhaust ventilation in a safe manner to maintain the ambient workplace atmosphere below the relevant PEL. 

Cleaning and Maintenance: Use HEPA vacuum and/or water cleaning systems. Never dry sweep or use compressed air.

Preventive Maintenance Programs: Preventive maintenance programs should be developed to ensure a correct procedure for the cleaning and operation of work equipment.

 

Personal Protective Equipment

Eye/Face Protection: During Fabrication operations, use dust-proof goggles or safety glasses with side shields.8

Hand and Skin Protection:  Cotton or leather work gloves9 and steel-toed shoes should be worn when handling and transporting the product. During the Fabrication Process protective clothing should be worn to minimize cuts and/or skin exposure to dust. Wash hands before eating, drinking, smoking, or using toilet facilities. Wash thoroughly after work using soap and water. Promptly remove dusty clothing (which is a source of respirable silica) and launder safely, preferably on site, separately from other clothes, before reuse. 

Respiratory Protection: Properly fitted respiratory protection equipment approved by the National Institute for Occupational Safety and Health (NIOSH; USA) for protection against organic vapors and dusts is necessary to avoid inhalation of crystalline silica during the Fabrication Process of the product, and other processes that generate dust. The appropriate respirator selection depends on the type and magnitude of exposure.10 Use a positive pressure air supplied respirator if there is a potential for an uncontrolled release, exposure levels are not known, or under any other circumstance where air purifying respirators may not provide adequate protection.

Medical Surveillance: Each worker should undergo relevant health surveillance prior to exposure and at regular intervals thereafter.

Respiratory Effects

Crystalline Silica (SiO2)

Repeated, long-term exposure to respirable crystalline particles of a very small size (less than 10 microns) may cause silicosis, an incurable, progressively disabling and sometimes fatal lung disease.  Silica dust particles become trapped in lung tissue, causing inflammation and scarring and reducing the lungs’ ability to take in oxygen. Symptoms of silicosis can include progressive shortness of breath, cough and fatigue.  Safety measures including wet processing and the use of effective respiratory protection will reduce the burden of inhaled dust and prevent the disease.

Titanium Dioxide (TiO2)

Exposure to respirable titanium dioxide particles may cause lung fibrosis and nuisance particulate accumulation in lungs. NIOSH recommends exposure limits of 2.4 mg/m3 for fine TiO2 as time-weighted average (TWA) concentrations for up to 10 hours per day during a 40-hour work week. These recommendations represent levels that over a working lifetime are estimated to reduce risks of lung cancer to below 1 in 1,000.

Carcinogenicity: The following components are listed by IARC, NTP, OSHA or ACGIH as carcinogens.

Silica, crystalline (quartz and cristobalite) Group 1 carcinogenic to humans Known to be a carcinogen Yes regulates as carcinogen A2 suspected human carcinogen

Teratogenicity: No data

Mutagenicity: No data

Name of toxicologically synergistic products: No data

Specific Target Organ Toxicity Single and Repeated Exposure:

Silicosis is caused by the inhalation and retention of respirable crystalline silica dust. Silicosis can exist in several forms, chronic and accelerated (acute). Chronic silicosis is the most common form of silicosis and can occur after many years of exposure to relatively low levels of airborne respirable crystalline silica dust. It is further defined as either simple or complicated silicosis. Simple silicosis is characterized by lung lesions (shown as radiographic opacities) less than 1 centimetre in diameter, primarily in the upper lung zones. Simple silicosis may not be associated with symptoms, detectable changes in lung function, or disability. Simple silicosis may be progressive and may develop into complicated silicosis or progressive massive fibrosis (PMF). Complicated silicosis or PMF is characterized by lung lesions (shown as radiographic opacities) greater than 1 centimetre in diameter. Symptoms, if present, are shortness of breath, wheezing, cough, and sputum production.
