How should regulated areas be demarcated?

The correct approach to demarcating regulated areas emphasizes methods that effectively minimize the presence of personnel within those spaces to ensure safety. This approach acknowledges the importance of protecting individuals from potential exposure to harmful substances, such as asbestos, by reducing access to these areas.

Using methods that minimize ingress helps to create a safety buffer and control exposure risks, which is paramount in asbestos-related work. While bright signs can alert individuals to the presence of a regulated area and physical barriers like ropes can help cordon off the space, the primary objective is to limit the number of people who are allowed in.

Other methods, like painting, may not provide adequate warnings or restrictions on entry and can be less effective in preventing access when compared to more comprehensive strategies. Thus, focusing on minimizing personnel access is central to maintaining a safe work environment.
