What does NFPA® 1901 require to be listed on a placard in every apparatus?

The requirement from NFPA® 1901 that is specified for placards on every apparatus is to include the vehicle height and weight. This is crucial for several reasons. First, the height of the vehicle is critical for navigating under bridges, canopies, and other overhead obstacles. Knowledge of the vehicle's height helps operators avoid accidents and damage when responding to emergencies or traveling through urban environments.

Similarly, the weight of the vehicle is essential for ensuring safe operation. Fire apparatus must adhere to weight limits for roads and bridges, and understanding the weight allows for proper loading and balancing of equipment and personnel. Including this information on a placard makes it immediately accessible to the driver or operator, promoting safety and compliance with regulations.

While other options might provide useful information regarding the apparatus, they do not meet the specific requirements laid out in NFPA® 1901 for placard contents, emphasizing the importance of vehicle height and weight as a priority for operational safety.
