Chemical Composition/Ingredients
The GHS is an acronym for The Globally Harmonized System of Classification and Labelling of Chemicals. The GHS is a system for standardizing and harmonizing the classification and labelling of chemicals. Chemicals are associated with codes that define their health, physical and environmental hazards.This universal hazard communication system was developed to ensure that employers, employees and consumers are provided with adequate, practical, reliable and comprehensible information on the hazards of chemicals, so that they can take effective preventive and protective measure for their own health and safety.
Advanced
The GHS classifications for chemicals associated with products in this database may be viewed by selecting the "Advanced" button on the Chemical Ingredients tables. Since this is a work in progress, GHS classifications may not be shown for all chemical ingredients.-
Primary Chemical Name is the standard name assigned to a chemical substance.
ChemicalChemical Abstracts Service Registry Number is a unique identifier for a chemical and its synonyms. CAS numbers identify the chemical, but not its concentration or specific mixture. CAS Registry Numbers are assigned by the Chemical Abstracts Service, a division of the American Chemical Society. For more information: www.cas.org
CAS No./ID
We have assigned "ID numbers" (with 6 leading zeros or nines, e.g., 000000-xx-x , 888888-xx-x) or 999999-xx-x) for blends and chemicals that do not have CAS numbers.Percent of chemical in preparation.

Acute health effects
From SDS:
Hazards Identification
Emergency Overview
Danger. May cause cancer. Causes skin irritation. Causes serious eye irritation. Causes damage to organs through prolonged or repeated exposure. Suspected of damaging the unborn child. Can cause silicosis and other permanent lung damage.
Potential Health Effects
Eye Contact: Causes serious eye irritation
Skin Contact: Causes skin irritation.
Inhalation: Dust may cause upper respiratory irritation.
Ingestion: May cause harmful effects if swallowed. -
Chronic health effects
From SDS:
In addition to cancer, breathing of silica over a period of time can cause damage to the lung tissue and silicosis after long exposure at low concentrations causing shortness of breath, fever, coughing, and weight loss. Prolonged and repeated exposure to respirable silica-containing dust may also cause autoimmune disease, kidney disease, tuberculosis, nonmalignant respiratory disease, and bronchitis.
In addition to cancer, prolonged or repeated skin contact may result in dryness and irritation of the skin. Long term skin exposure to asphalt can increase sensitivity to the sun and may cause discoloration. Oxidized asphalt may also cause irritation of the upper respiratory tract. -
Carcinogenicity
This product contains asphalt. The National Institute for Occupational Safety and Health has concluded that the fumes of heated roofing asphalt are a potential occupational carcinogen. Asphalt may also cause irritation of the respiratory tract. The physical nature of this product may help limit any inhalation hazard from asphalt during application in its hardened state. However, physical forces such as sawing, grinding, drilling and other demolition work on this product may liberate dust containing asphalt. Burning or heating of the product may cause fumes, vapors or mists.This product contains crystalline silica(quartz). IARC has determined that crystalline silica inhaled in the form of quartz from occupational sources is carcinogenic to humans (Group 1). IARC concluded that there was sufficient evidence in humans and animals for the carcinogenicity of inhaled crystalline silica in the form of quartz from occupational sources. The NTP has classified silica as known to be a human carcinogen. The physical nature of this product may help limit any inhalation hazard from crystalline silica during application and in its hardened state. However, physical forces such as grinding, drilling and other demolition work on this product may liberate crystalline silica dust. -

First Aid
Eye Contact: Immediately flush eyes with plenty of cool water for at least 20 minutes, occasionally lifting the eye lids to ensure thorough rinsing. Get medical attention if irritation persists.Skin Contact: Clean any exposed skin with warm soapy water if possible. If not, and a waterless hand cleaner is used, it should be without pumice. Do not use solvents or thinners to remove material from skin. Get medical attention if irritation persists or develops.Inhalation: If inhalation of cured product particles, fumes, vapors, or mist occurs, remove person to fresh air. Drink water to clear throat or blow nose to clear. If not breathing, give artificial respiration or give oxygen by trained personnel and get immediate medical attention.Ingestion: If swallowed, do not induce vomiting. If vomiting occurs, keep head lower than hips to avoid aspiration of vomit into the lungs which can cause inflammation or pneumonitis. Call poison control center or get immediate medical attention.
