Is it true that hydraulic fluids used in aerial lifts around energized lines must be fire resistant?

The assertion that hydraulic fluids used in aerial lifts around energized lines must be fire-resistant is accurate, as fire-resistant fluids are typically required to minimize the risk of ignition in the event of a leak or spill, especially in environments with potential electrical hazards. Using fire-resistant hydraulic fluids helps ensure safety when working near energized lines, as these fluids can significantly reduce the likelihood of fire and the severity of any incidents that may occur.

While options that suggest the requirement varies based on voltage or local regulations do have merit in certain contexts, they don't override the fundamental safety principle of using fire-resistant fluids when working in proximity to live electrical lines. The focus on using materials that help mitigate risks associated with fire and electrical hazards is crucial in maintaining a safe working environment. Thus, the expectation for hydraulic fluids to be fire-resistant under such circumstances is grounded in best practices for workplace safety.
