What must you carry for all races?

In the context of participating in races, especially those related to firefighting or emergency response situations, carrying a breathing apparatus is essential for ensuring safety. The breathing apparatus is designed to provide breathable air in environments where the atmosphere may be compromised, such as in smoke or hazardous conditions. This is particularly important for firefighters or rescue personnel who may encounter situations involving toxic smoke, chemicals, or other respiratory hazards.

Having a breathing apparatus allows individuals to perform their duties effectively while minimizing the risk of asphyxiation or inhalation of harmful substances. While the other options such as a fire extinguisher, water pack, and first aid kit are important for various reasons, they do not provide the same critical level of safety in environments where air quality is a concern. Therefore, a breathing apparatus is crucial for ensuring the health and safety of participants during races.
