What type of markers should be placed to indicate obstacles to be avoided?

The use of temporary reference markers is essential for indicating obstacles that need to be avoided in various environments, especially in construction and heavy equipment operation. These markers serve as visible indicators that can be easily set up and removed as needed, ensuring that operators and workers remain aware of potential hazards in the vicinity. Their temporary nature allows for flexibility in adjusting the layout of a work area, making them ideal for dynamic situations where obstacles may change over time.

While hazard signs and traffic cones can also indicate hazards, they serve different, more permanent purposes or are standardized for traffic guidance rather than being tailored for temporary job site adjustments. Reflective tape is useful for visibility in low-light conditions but does not provide the same level of clear identification or versatility as temporary reference markers. Thus, temporary reference markers are the best choice for effectively indicating obstacles to be avoided in a heavy equipment operation setting.
