Which message is displayed on a soil fumigation buffer zone warning sign?

The message displayed on a soil fumigation buffer zone warning sign is critical for ensuring safety and preventing exposure to toxic substances used in fumigation. The phrase “Do Not Walk” specifically communicates to individuals that they should avoid walking through the area, which is designed to minimize the risk of unintentional exposure to harmful chemicals.

This warning is essential as it helps protect both the general public and workers by clearly designating the buffer zone around the treated site. It conveys actionable guidance without causing undue alarm, as it implies that while access is restricted, it is also focused on foot traffic.

In contrast, other options may imply different levels of restriction. For example, “Stay away from this area” might seem redundant or unclear about specific actions, while “No Entry Permitted” could suggest a broader restriction that may not be representative of foot traffic specifically. “Danger: Toxic Chemicals” conveys concern but may not actively instruct individuals on what to do in the vicinity of fumigation. Thus, the phrase "Do Not Walk" is more appropriate for the purpose of the sign in a soil fumigation context.
