Section 13- Disposal Considerations

This section provides guidance on proper disposal practices, recycling or reclamation of the chemical(s) or its container, and safe handling practices. To minimize exposure, this section should also refer the reader to Section 8 (Exposure Controls/Personal Protection) of the SDS. The information may include: -Description of appropriate disposal containers to use. -Recommendations of appropriate disposal methods to employ. -Description of the physical and chemical properties that may affect disposal activities. -Language discouraging sewage disposal. -Any special precautions for landfills or incineration activities

Section 10: Stability and Reactivity

describes the reactivity hazards of the chemical and the chemical stability information. Reactivity -Description of the specific test data for the chemical(s). This data can be for a class or family of the chemical if such data adequately represent the anticipated hazard of the chemical(s), where available. Chemical stability -Indication of whether the chemical is stable or unstable under normal ambient temperature and conditions while in storage and being handled.- Description of any stabilizers that may be needed to maintain chemical stability. -Indication of any safety issues that may arise should the product change in physical appearance. Other -Indication of the possibility of hazardous reactions, including a statement whether the chemical will react or polymerize, which could release excess pressure or heat, or create other hazardous conditions. Also, a description of the conditions under which hazardous reactions may occur. -List of all conditions that should be avoided (e.g., static discharge, shock, vibrations, or environmental conditions that may lead to hazardous conditions). -List of all classes of incompatible materials (e.g., classes of chemicals or specific substances) with which the chemical could react to produce a hazardous situation. -List of any known or anticipated hazardous decomposition products that could be produced because of use, storage, or heating. (Hazardous combustion products should also be included in Section 5 (Fire-Fighting Measures) of the SDS.)

Section 9: Physical and Chemical Properties

identifies physical and chemical properties associated with the substance or mixture. The minimum required information consists of: -Appearance (physical state, color, etc) -upper/lower flammability or explosive limits; -Odor -Vapor pressure -odor threshold -vapor density -pH -Relative density -melting point/freezing point -solubility -initial boiling point and boiling range -flash point -evaporation rate -flammability (solid gas) -Partition coeffcient: n-octanol/water -auto-ignition temperature -viscosity

Section 1: Identification

identifies the chemical and recommended uses. Also provides the essential contact information of the supplier. Product identifier used on the label and any other common names or synonyms by which the substance is known. Name address, phone number of the manufacturer, importer, or other responsible party, and emergency phone number. recommended use of the chemical such as a brief description of what it actually does, such as flame retardant and any restrictions on use including recommendations given by the supplier

Section 11: Toxicological Information

identifies toxicological info and health effects, what happens if inhaled, ingested, skin and eye contact. -Information on the likely routes of exposure (inhalation, ingestion, skin and eye contact). The SDS should indicate if the information is unknown. -Description of the delayed, immediate, or chronic effects from short- and long-term exposure. -The numerical measures of toxicity (e.g., acute toxicity estimates such as the LD50 (median lethal dose)) - the estimated amount [of a substance] expected to kill 50% of test animals in a single dose. -Description of the symptoms. This description includes the symptoms associated with exposure to the chemical including symptoms from the lowest to the most severe exposure. -Indication of whether the chemical is listed in the National Toxicology Program (NTP) Report on Carcinogens (latest edition) or has been found to be a potential carcinogen in the International Agency for Research on Cancer (IARC) Monographs (latest editions) or found to be a potential carcinogen by OSHA

Section 8-Exposure Controls/Personal Protection

indicates exposure limits, engineering controls, and personal protective measures that can be used to minimize worker exposure. Required information consists of: -OSHA Permissible Exposure Limits (PELs), American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs), and any other exposure limit used or recommended by the chemical manufacturer, importer, or employer preparing the safety data sheet, where available -appropriate engineering controls ( use local exhaust ventilation, or use only in an enclosed system) -recommended for personal protective measures to prevent illness or injury from exposure to chemicals such as personal protective equipment (PPE) (appropriate types of eye, face, skin or respiratory protection needed based on hazards and potential exposure). -Any special requirements for PPE, protective clothing or respirators ( type of glove material, such as PVC or nitrile rubber gloves; and breakthrough time of the glove material).

Section 7: Handling and Storage
