Where should caution stickers be installed when working near power lines according to ASME B30.3?

Caution stickers are essential tools for promoting safety around cranes, especially when operating near power lines. According to ASME B30.3, it is specified that caution stickers should be installed at the operator's station and at the base of the crane. This placement is critical because it ensures that both the operator and crew members are immediately reminded of the hazards associated with proximity to electrical power lines, promoting a heightened awareness of safety protocols.

Having caution stickers at the operator's station directly informs the crane operator about the risks, fostering a mindset of vigilance. Installing them at the base of the crane ensures that anyone approaching the crane is also aware of these dangers, which is crucial in preventing accidents and ensuring that all personnel on site are informed and can act accordingly.

Other options, while they may offer some level of caution, do not provide the same comprehensive awareness that placing stickers at both the operator's station and at the base of the crane does. For instance, placing caution stickers solely on lifting hooks or on the crane's control panel limits visibility and might not effectively communicate the hazards to all relevant personnel. Furthermore, marking only the job site entrance may fail to reach individuals already working near the crane and its operations. Thus, the chosen method of placement aligns with best
