What is considered the best source of information on a specific hazardous material?

• A. Safety Data Sheet (SDS)
• B. Emergency Response Guidebook (ERG)
• C. Material Safety Data Sheet (MSDS)
• D. Local fire department

Answer: (C)

The best source of information on a specific hazardous material is the Safety Data Sheet (SDS). The SDS provides detailed information about the properties of a hazardous substance, including its potential health effects, safety and handling precautions, and emergency response measures. This comprehensive document is designed to ensure that workers and emergency responders have the necessary information to safely handle and respond to incidents involving that material.

Though the Material Safety Data Sheet (MSDS) was previously used and contains similar information, the SDS is the updated format that aligns with the Globally Harmonized System (GHS) of classification and labeling of chemicals, making it more consistent and easier to understand across different countries and industries.

The Emergency Response Guidebook (ERG) is valuable in providing guidance for first responders during emergencies involving hazardous materials but does not offer the in-depth information available in an SDS. Lastly, while the local fire department can be a useful resource for emergency situations, they may not always have specific details about a particular hazardous material as comprehensively as an SDS does.
