The International Agency for Research on Cancer (IARC) has determined that crystalline silica in the form of quartz or
cristobalite that is inhaled from occupational sources is carcinogenic to humans (Group 1- carcinogenic to humans). Refer
to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (published in June 1997) in conjunction with the use of
these materials. The National Toxicology Program (NTP) classifies respirable crystalline silica as "known to be a human
carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial
Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (Group A2).
Breathing dust containing respirable crystalline silica may not cause noticeable injury or illness even though permanent
lung damage may be occurring. Inhalation of dust may have the following serious chronic health effects: Excessive
inhalation of respirable dust can cause pneumoconiosis, a respiratory disease, which can result in delayed, progressive,
disabling and sometimes fatal lung injury. Symptoms include cough, shortness of breath, wheezing, non-specific chest
illness and reduced pulmonary function. Smoking exacerbates this disease. Individuals with pneumoconiosis are
predisposed to develop tuberculosis. There is some evidence that breathing respirable crystalline silica or the disease
silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune
system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease. Prolonged,
repeated, or high exposures may cause weakness and depression of the central nervous system.
Ethylene Glycol may cause kidney and liver damage upon prolonged and repeated overexposures. Studies have shown
that repeated inhalation of ethylene glycol has produced adverse cardiovascular changes in laboratory animals. Ethylene
glycol has been shown to cause birth defects in laboratory animals.
Primary Route(s) Of Entry: Skin Contact, Skin Absorption, Inhalation
Medical Conditions which May be Aggravated by Exposure: If dry sanded, asthma and asthma-like conditions may
worsen from prolonged or repeated exposure to dust.
Carcinogenicity:
First Aid - Eye Contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get
medical attention immediately.
First Aid - Skin Contact: Wash off immediately with plenty of water for at least 15 minutes. Wash off immediately with
soap and plenty of water. Remove and wash contaminated clothing. If skin irritation persists, call a physician.
First Aid - Inhalation: If inhaled, remove to fresh air. If breathing is difficult, leave the area to obtain fresh air. If
continued breathing difficulty is experienced, get medical attention immediately.
First Aid - Ingestion: Call a physician or Poison Control Center immediately. Do not induce vomiting.
Note to Physician: None.
COMMENTS: If over-exposure occurs, call your poison control center at 1-800 -222-1222.
