What device warns crane operators of electrical hazards?

The proximity warning device is specifically designed to alert crane operators of potential electrical hazards in their vicinity. These devices use various methods, such as sensors and alarms, to detect when the crane is approaching power lines or other electrical infrastructures. When the crane gets too close to a hazard, the proximity warning device activates a warning signal to inform the operator, allowing them to take appropriate actions to avoid accidents. This proactive approach significantly enhances safety by preventing dangerous situations involving electricity, which is particularly critical when operating heavy machinery like cranes.

Other options, while they may relate to safety in general, do not have the specific designation or functionality that a proximity warning device has in the context of protecting against electrical hazards. For instance, a safety alarm system could refer to a range of general alerts that do not necessarily pertain to electrical issues specifically. An electrical safety monitor may suggest monitoring systems for electrical functions, but it does not actively provide warnings related to proximity. Finally, a hazard notification system could encompass various hazards but lacks the focused application that a proximity warning device offers in terms of real-time alerts regarding electrical dangers specifically.
