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.
A mixture of diisodecyl phthalate and diisononyl phthalate has been tested in a two-generation toxicity study in laboratory
animals. No effects on reproductive parameters were seen. However, a small but statistically significant increase in early
offspring mortality was seen at high oral doses. The significance of this to humans is uncertain.
The mixture of phthalate esters contained within this product has been shown to cause developmental effects at high doses
in laboratory animals when administered orally by gavage in a developmental study and developmental and fertility effects
when administered at high doses by feed in a two-generation reproduction study. The potential risk from occupational and
consumer exposure is considered to be very low, based on limited relevance of the rodent findings to humans and the large
safety margins between exposure and the effect levels.
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: None known.
Carcinogenicity:
First Aid - Eye Contact: In case of contact, immediately flush eyes with large quantities of water for at least 15 minutes
until irritation subsides. Get medical attention immediately.
First Aid - Skin Contact: Wash off immediately with soap and plenty of water for at least 15 minutes. Get medical aid if
symptoms persist. In case of contact, immediately flush skin with plenty of water while removing contaminated clothing and
shoes. 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: If you experience difficulty in breathing,
