Shipping papers for hazardous materials must be visible and accessible to whom at all times?

Shipping papers for hazardous materials must be visible and accessible to emergency personnel at all times to ensure a prompt and effective response in case of an incident. In the event of an emergency, first responders need to quickly assess the situation, including identifying the type of hazardous materials involved, to implement appropriate safety measures and containment strategies. Having immediate access to this critical information can significantly mitigate risks and help protect both human life and the environment.

While there may be other individuals who find it beneficial to know the shipping information, such as shipping company representatives and other drivers, their need for access does not equate to the urgency and importance placed on emergency responders. Passengers also do not require access to this information for safety reasons. Thus, the focus on emergency personnel highlights the necessity of preparing for accidents and emergencies involving hazardous materials.
