What document helps to classify hazards on the base of UN numbers?

1. Safety Data Sheet

2. Emergency Response Guidebook

3. Material Safety Data Sheet

4. Hazardous Materials Regulations

The correct answer is: Emergency Response Guidebook

The Emergency Response Guidebook (ERG) is designed specifically to assist first responders in identifying and managing hazardous materials incidents. It classifies hazards based on United Nations (UN) numbers, which are numerical identifiers assigned to hazardous materials that facilitate immediate recognition of the specific risks associated with various substances. This guide provides crucial information, including emergency response recommendations, potential hazards, and safety measures, thereby enabling a quick and effective response in emergency situations. In contrast, a Safety Data Sheet (SDS) provides detailed information about a particular chemical, including handling procedures, toxicity, and first aid measures, but it does not classify hazards using UN numbers. A Material Safety Data Sheet (MSDS) functions similarly to an SDS but may be less comprehensive in its structure and requirements. Hazardous Materials Regulations consist of legal requirements for the transport and handling of hazardous materials but are not a practical tool for classification based on UN numbers during an emergency response. Thus, the ERG stands out as the relevant resource for classifying hazards effectively using UN numbers.
