Warning signs at the location of asbestos work must be readable up to how many feet away?

• A. 10 Feet
• B. 20 Feet
• C. 30 Feet
• D. 40 Feet

Answer: (B)

Warning signs for asbestos work are placed so that anyone approaching the site can see and read them in time to recognize a hazard before entering the area. The distance chosen, twenty feet, gives a practical balance: it’s far enough away to catch attention along approaches and allow a worker to stop or take precautions, yet not so distant that the sign isn’t effectively communicating the danger as you near the regulated area. A shorter distance like ten feet could reduce reaction time, while longer distances such as thirty or forty feet aren’t typically necessary for the typical access routes and can create confusion about where the boundary actually lies. So twenty feet is the standard readable range for these warning signs.
