Combustible Gas Detection System

If the explosive gas detection system sensors detects a 50 percent concentration of the lower explosive limit for a gas and maintains that level for six continuous seconds, a red LED on the system panel illuminates and an alarm sounds.

If a red LED illuminates when driving, quickly bring the vehicle to a safe stop. Apply the park brake, turn off the ignition, and press the eStop button on the dash prior to exiting the cab. Immediately call emergency services.
