# 7.3 Safety Requirements

### 7.3.1 Kill Switch

Participating ships must have a clearly visible and accessible kill switch physically on board the ship, which disengages all motorized and moving parts. Additionally, there must be a remotely controllable kill switch with the same function. 

Teams must also implement a “naturally off system with delay”. This should function in a way that turns off all autonomous movement after a team has lost radio communication with their vessel for 60 seconds. This is an extra safety in case one loses radio communication.

### 7.3.2 Firebox

The vessel must include a firebox, which should contain and prevent fire from spreading. This firebox should be designed to withstand and resist the spread of flames for 4 minutes, thereby providing a window of time for a response team to shut down the fire. The firebox need to contain complete power supply and additional firehazards. Sensors and batteries can be store outside the firebox

### 7.3.3 Waterproof

All components and systems on the vessel should be waterproof or water resistant to prevent damage or operational disruption. This is to ensure safety and for the vessel to function during different weather conditions. 

### 7.3.4 Marking

All sharp, pointy, moving or other sensitive parts must be covered and marked.
