Labeling and Posting

Chemical substance labeling:

• Containers must have labels that clearly identify their contents
• Direct hazards such as toxicity and exposure symptoms should appear on the label
• Containers should be labeled prior to mixing, dispensing, or transferring
• Materials should be returned to designated storage locations when not in use
• Labels and Material Safety Data Sheets (MSDS) are required for all chemicals stored or used in a lab and should be read and understood

Equipment should be labelled with sufficient information to enable laboratory personnel to find additional information from other sources.

• Manufacturer’s instructions
• Intended use and limitations
• Shutdown procedures, especially for equipment containing hazardous material
• Hazards and required maintenance and inspection
