  • Present above their cut-off/concentration limit, or
  • Present a health risk below the cut-off/concentration limit.
  • The concentration (exact percentages) of each ingredient must be specified except concentration ranges may be used I the following situations:
  • A trade secret,
  • There is batch-to-batch variation, or

  • Recommendations of special protective equipment or precautions for firefighters.

Section 6 provides recommendations on the appropriate response to spills, leaks, or releases, including containment and clean up practices to prevent or minimize exposure to people, properties, and/or the environment.  It may also include recommendations distinguishing between responses for large and small spills where the spill volume has a significant impact on the hazard.  Information required in this section includes:

  • Use of personal precautions (such as removal of ignition sources or providing sufficient ventilation) and protective equipment to prevent contamination of skin, eyes, and/or clothing.

Section 8 indicates the exposure limits, engineering controls, and personal protective measures that can be used to minimize exposures.  Information required in this section includes:

  • 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 manufacturer, importer, or employer preparing the SDS.
  • Appropriate engineering controls (i.e., use local exhaust ventilation, or use only in a closed system).
  • Recommendations for personal protective measures to prevent illness or injury from exposure, such as personal protective equipment (PPE) (e.g., eye, face, skin, or respiratory protection needed).
  • Any such special requirements for PPE, protective clothing or respiratory protection (e.g., type of glove material and breakthrough time of the glove material).

体育365Section 9 identifies physical and chemical properties associated with the substance or mixture.  The minimum required information required in this section includes:

The SDS may not contain every item on the above list as information may not be relevant or is not available.  When this occurs, a notation to that effect must be made for that chemical property.  Manufacturers may also add other related properties such as the dust deflagration index (Kst) for combustible dusts, used to evaluate a dust’s explosive potential.

Section 10 describes the reactivity hazards of the chemical and chemical stability.  This section is divided into three sections; reactivity, chemical stability, and other.  Information required in this section includes:

Reactivity

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 of polymerize, which could release excess pressure of heat, or create other hazardous conditions.  Also, a description of the conditions under which a hazardous reaction 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 decomposition products should also be included in Section 5, Fire-Fighting Measures.

Section 11 provides toxicological and health effects information or indicates that such data are not available.  Information required in this section includes:

  • Information on the likely routes of exposure (inhalation, ingestion, skin and eye contact).  The SDS should also indicate if the information is unknown.
  • Description of the delayed, immediate, or chronic effects from short- and long-term exposures.
  • The numerical measures of toxicity (e.g., acute toxicity estimates such as the LD50 (medial 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 fro the lowest to the most severe exposures.
  • Indication of whether is listed in the National Toxicity 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 edition) or found to be a potential carcinogen by OSHA.

Section 12 provides information to evaluate the environmental impact of the chemical(s) if it were released to the environment.  Information in this section may include:

  • Data from toxicity tests performed on aquatic and/or terrestrial organisms, where available (e.g., acute or chronic aquatic toxicity data for fish, algae, crustaceans, and other plants; toxicity data on birds, bees, plants).
  • Whether there is a potential for the chemical to persist and degrade in the environment either through biodegradation or other processes, such as oxidation or hydrolysis.

Section 13 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.  Information in this section 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 of incineration activities.

  • UN proper shipping name.
  • Transport hazard class(s).
  • Packing group number, if applicable, based on the degree of hazard.

Section 15 identifies the safety, health, and environmental regulations specific for the product that is not indicated anywhere else on the SDS.  Information in this section may include:

  • Any national and/or regional regulatory information of the chemical or mixtures (including any OSHA, Department of Transportation, Environmental Protection Agency, or Consumer Product Safety Commission regulations).

Section 16 indicates when the SDS was prepared or when the last known revision was made.  The SDS may also state where the changes have been made to the previous version.  You may wish to contact the supplier for an explanation of the changes.  Other useful information may also be included in Section 16.
