Hazard Communication Standard: Safety Data Sheets - Sections 5-8

Section 5: Fire-Fighting Measures
This section provides recommendations for fighting a fire caused by the chemical. The required information consists of:
  • Recommendations of suitable extinguishing equipment, and information about extinguishing equipment that is not appropriate for a particular situation.
  • Advice on specific hazards that develop from the chemical during the fire, such as any hazardous combustion products created when the chemical burns.
  • Recommendations on special protective equipment or precautions for firefighters.
Section 6: Accidental Release Measures
This section provides recommendations on the appropriate response to spills, leaks, or releases, including containment and cleanup practices to prevent or minimize exposure to people, properties, 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. The required information may consist of recommendations for:
  • Use of personal precautions (such as removal of ignition sources or providing sufficient ventilation) and protective equipment to prevent the contamination of skin, eyes, and clothing.
  • Emergency procedures, including instructions for evacuations, consulting experts when needed, and appropriate protective clothing.
  • Methods and materials used for containment (e.g., covering the drains and capping procedures).
  • Cleanup procedures (e.g., appropriate techniques for neutralization, decontamination, cleaning or vacuuming; adsorbent materials; and/or equipment required for containment/clean up)
Section 7: Handling and Storage
This section provides guidance on the safe handling practices and conditions for safe storage of chemicals. The required information consists of:
  • Precautions for safe handling, including recommendations for handling incompatible chemicals, minimizing the release of the chemical into the environment, and providing advice on general hygiene practices (e.g., eating, drinking, and smoking in work areas is prohibited).
  • Recommendations on the conditions for safe storage, including any incompatibilities. Provide advice on specific storage requirements (e.g., ventilation requirements)
Section 8: Exposure Controls/Personal Protection
This section indicates the exposure limits, engineering controls, and personal protective measures that can be used to minimize worker exposure. The 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 (e.g., use local exhaust ventilation, or use only in an enclosed system).
  • Recommendations for personal protective measures to prevent illness or injury from exposure to chemicals, such as personal protective equipment (PPE) (e.g., 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 (e.g., type of glove material, such as PVC or nitrile rubber gloves; and breakthrough time of the glove material).
