Why is it advised to have more than one reference manual on hand during an incident?

Having multiple reference manuals available during an incident is important because different manuals are designed to address various hazardous situations, materials, and scenarios. Each reference source may provide unique insights, protocols, and guidelines tailored to specific types of hazardous materials or emergency responses. In scenarios involving hazardous materials, the conditions can change rapidly, and having multiple resources allows responders to access a broader range of information, ensuring a more comprehensive understanding of the risks involved and the appropriate response strategies.

While other factors, such as the requirement for emergency responders or the potential for outdated information, may play a role in preparedness, the primary advantage lies in the diversity of information across different manuals. This diversity helps responders make more informed decisions, ultimately enhancing safety and effectiveness during an incident. Having access to varied resources can also facilitate better problem-solving and adaptability in real-time, which is crucial in emergencies involving hazardous materials.
