Ground Personnel, Spotters & Signals
When Ground Personnel Are Needed
Ground personnel should be used for spotting, signaling near hazards, and in blind spots. Heavy equipment operators have significant blind spots around their machines. Ground personnel act as the eyes and ears where the operator cannot see, directing movements and warning of hazards.
Back-Up Alarm Purpose
The back-up alarm warns personnel when the machine is in reverse. It is a critical safety device that alerts workers in the area that the equipment is backing up. The alarm must be functional and audible above site noise. If the alarm is not working, the machine should not be operated until it is repaired.
Standard Hand Signals
Operators and ground personnel must know standard hand signals for communication. The signal for stop is arms extended with palms down in a sweeping motion. Other signals include raise, lower, swing left, swing right, and emergency stop. Both the operator and spotter must agree on signals before work begins.
Spotter Safety Rules
Spotters must never stand in the machine's travel path. Maintain eye contact with the operator at all times. If eye contact is lost, the operator must stop immediately.
Ground personnel and spotters are used for spotting, signaling near hazards, and covering blind spots. The hand signal for stop is arms extended with palms down. Back-up alarms must be functional on all equipment.
