Chemical data sheet for:

CAS Number - Chemical Abstract Service registry number. Unique identification number assigned to this chemical by the American Chemical Society.

UN/NA Number - The United Nations-North America number (also called UN number or DOT number). Four-digit number identifying an individual chemical or group of chemicals with similar characteristics. Required on shipping papers; often shown on placards or labels. This numbering system was developed by the U.S. Department of Transportation, and then became the UN standard system for classifying hazardous materials.

STCC Number - Standard Transportation Commodity Code. Sounds like "Stick number." Seven-digit chemical identification code used by the Association of American Railroads. A STCC number beginning with "49" indicates a hazardous material.

CHRIS Code - Three-letter code used by the U.S. Coast Guard to identify individual chemicals included in its CHRIS (Chemical Hazards Response Information System) manual.

NFPA 704 - Diamond-shaped label containing codes indicating the level of the chemical's toxic, flammability, and reactivity hazard, along with special hazards such as water- and air-reactivity. See a guide to the "NFPA diamond."

DOT Hazard Label - Required DOT hazard warning label for the chemical (e.g., "Flammable Liquid," "Corrosive"). This label must be displayed on shipped packages, railroad tank cars, and tank trucks according to specifications described in 49 CFR 172.

General Description - Brief description of the general appearance, behavior, and hazardousness of the chemical.

List of data sources.

Reactivity Alerts - Special alerts for chemicals that are especially reactive. See a table of reactivity alerts and their definitions.

Air & Water Reactions - Special alerts for chemicals that react with air and/or water or moisture.

Fire Hazard - Description of the chemical's flammability, byproducts that may evolve if the chemical is burned, and risk of explosion.

Health Hazard - Description of the health hazards of the chemical, such as toxicity, flammability, and corrosivity.

Reactivity Profile - Description of the potential reactivity between the chemical and other chemicals, as well as its reactivity with air and water, and any other intrinsic reactive hazards (e.g., polymerizability, peroxidizability).

Reactive Groups - The reactive group, or groups, to which the chemical was assigned, based on its known chemistry. Reactive groups are categories of chemicals that react in similar ways because they are similar in their chemical structure. Read more about reactive groups.

Special WMD note - For chemicals that historically have been used as weapons of mass destruction (WMDs) or that could be used as WMDs, a special note describes the physical clues that can help you to assess whether an attack has taken place.

List of data sources.

Fire Fighting - Response recommendations for fire incidents in which the chemical is involved.

Non-Fire Response - Response recommendations for incidents not involving fire, in which the chemical is involved.

Protective Clothing - General recommendations.

First Aid - Recommended first aid treatment for people exposed to the chemical.

List of data sources.

Regulatory Names - Names under which this substance is regulated under Federal laws such as CERCLA ("Superfund"), EPCRA ("Title III of SARA"), RCRA, and the Clean Air Act of 1990.

CAA RMP - Indicates whether this chemical has been listed as a toxic, flammable, or explosive hazardous substance under Section 112(r) of the Clean Air Act. For listed chemicals, displays the Threshold Quantity listed in the Act. A facility is subject to the accidental release prevention provisions of the Act if more than the Threshold Quantity of at least one listed chemical is in a process at the facility.

CERCLA - Indicates whether this chemical is listed as a hazardous substance under CERCLA (40 CFR 302). For listed chemicals, displays the Reportable Quantity (RQ) listed in CERCLA. A facility must report spilled quantities in excess of the RQ to Federal, state, and local governments.

EPCRA 302 EHS - Indicates whether this chemical is an Extremely Hazardous Substance (EHS), identified by the U.S. Environmental Protection Agency as an acute inhalation toxic threat, and listed under EPCRA. For listed chemicals, displays the Threshold Planning Quantity listed in 40 CFR 355. When the storage quantity of an EHS chemical at a facility exceeds this threshold, the reporting, community right-to-know, and emergency planning requirements of EPCRA must be met.

TRI (EPCRA 313) - Indicates whether this chemical is included in a list of toxic chemicals covered under Section 313 of EPCRA. Facilities manufacturing, storing, or using at least one Section 313 chemical may be required to submit annual reports of the amount of each chemical released into the environment, either routinely or by accident (see 40 CFR 372).

RCRA chemical code - Four-character identification code assigned to this substance under the Resource Conservation and Recovery Act of 1976 (RCRA).
