Section 2
SECTION 2: Hazards identification
Emergency Overview Respirable dust from these products may contain crystalline silica, which is known to cause respiratory disease. (See Section 11 for more information)
Potential chronic health
Prolonged/repeated inhalation of respirable crystalline silica may cause delayed lung injury (e.g.: silicosis, lung cancer). Possible Health Effects Target Organs: Eyes, skin, nose and/or throat
Principle Routes of Exposure
Inhalation Acute effects: May cause temporary, mild mechanical irritation to the eyes, skin, nose and/or throat. Pre-existing skin and respiratory conditions may be aggravated by exposure.
2.1 Classification of the substance or mixture
Info Dust samples from these products have not been tested for their specific toxicity, but may contain more than 0.1% crystalline silica, for which the following apply: The International Agency for Research on Cancer (IARC) has classified crystalline silica inhaled in the form of quartz or cristobalite from occupational sources as carcinogenic to humans (Group 1). The Ninth Annual Report on Carcinogens (2000), prepared by the National Toxicology Program (NTP), classified silica, crystalline (respirable size), as a substance known to be a human carcinogen. The American Conference of Governmental Industrial Hygienists (ACGIH) has classified crystalline silica (quartz) as "A2-Suspected Human Carcinogen." The State of California, pursuant to Proposition 65, The Safe Drinking Water and Toxic Enforcement Act of 1986, has listed "silica, crystalline (airborne particles of respirable size)" as a chemical known to the State of California to cause cancer. The Canadian Workplace Hazardous Materials Information System (WHMIS) – Crystalline silica [quartz and cristobalite] is classified as Class D2A - Materials Causing Other Toxic Effects. The Hazardous Materials Identification System (HMIS) – Health 0* Flammability 0 Reactivity 0 Personal Protection Index X (Employer determined) (* denotes potential for chronic effects)
