What weather condition will prompt the discontinuation of hoisting a personnel platform?

The discontinuation of hoisting a personnel platform is necessary when dangerous conditions exist. This encompasses a wide range of potentially hazardous scenarios that may jeopardize the safety of personnel being lifted or the operation itself. Dangerous conditions can include not just extreme weather events such as severe storms or heavy precipitation but also other factors like electrical storms, visibility issues, or unforeseen obstacles in the lifting area.

While strong winds and heavy rain are specific weather conditions that can create danger, the term "dangerous conditions" provides a broader but pertinent context, indicating any environmental factor that would compromise safety. Therefore, if any conditions arise that are deemed dangerous, it is critical to halt operations to protect all individuals involved.

Sunny weather is typically not a reason to stop hoisting operations unless other risks are apparent, which is why it is not the right choice.
