EMERGENCY OVERVIEW
Warning! May cause severe eye irritation and injury. May cause skin irritation or burns. Inhalation of dust may
cause irritation of the nose, throat and respiratory tract. Repeated skin contact may result in allergic dermatitis.
Prolonged inhalation of respirable crystalline silica (quartz) may cause a disabling, progressive lung disease,
silicosis, and lung cancer.
See Section 11 for detailed information
4. FIRST AID MEASURES
Ingestion: Wash mouth with water. Do not induce vomiting. Seek immediate medical attention.
Skin Contact: Remove contaminated clothing and wash immediately with plenty of soap and water. Get medical
attention if irritation or other symptoms develop. Launder contaminated clothing before reuse.
Eye Contact: Rinse immediately with plenty of water for 15 minutes, while lifting the eyelids. Get immediate
medical attention.

11. TOXICOLOGICAL INFORMATION
PRODUCT HEALTH HAZARD INFORMATION
Skin: Contact with dry product may cause dryness of the skin. Contact with wet product or presence of product
on skin damp with sweat will cause irritation and possible serious burn. Repeated contact may result in allergic
reaction in some individuals.
Eye: May cause severe irritation and possible serious eye injury. Dust may cause physical (mechanical) eye
injury.
Inhalation: May cause irritation of the nose, throat and upper respiratory tract.
Ingestion: May cause irritation of the mouth and gastrointestinal tract.
Chronic Heath Effects: Chronic overexposure to any respirable dust will cause adverse effects on the lung.
Chronic overexposure to respirable crystalline silica may cause a progressive, disabling lung disease, silicosis
which may be fatal. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness and
reduced pulmonary function. This disease is exacerbated by smoking. The International Agency for Research on
Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz from occupational sources is
carcinogenic to humans (Group 1). The National Toxicology Program classifies respirable crystalline silica as

known to be a human carcinogen.. The American Conference of Governmental Industrial Hygienists (ACGIH)
classifies crystalline silica, quartz, as a suspected human carcinogen (A2).
