What should firefighters do if they encounter a “placard” on a vehicle?

Firefighters should refer to the placard to identify the contents and associated hazards because placards are crucial safety tools indicating the nature of hazardous materials being transported. These color-coded signs provide vital information about the potential risks, helping responders understand what they're dealing with. By accurately identifying the substances, firefighters can implement appropriate safety measures, such as selecting the right protective gear and developing a strategy to manage the situation effectively.

Using the placard for identification not only enhances the personal safety of the firefighting crew but also helps mitigate risks to the public and the environment. This information is critical in ensuring that the right emergency response procedures are followed, such as determining whether evacuation is necessary or what type of firefighting agent might be effective against a chemical fire. Therefore, consulting the placard is a fundamental step in ensuring overall safety and effective incident management.
