In the event of a hazardous material spill at your facility, are door signs used to notify individuals of the spill situation? Or do you use caution tape, cones, or some other physical barrier to prevent unauthorized entry into the hazardous material spill area?
When door signs are used rather than a physical barrier restricting access to the area, it is important to pay attention to how effective they are. I have witnessed cases of individuals seeing a door sign, and proceeding to enter the area out of curiosity. Larger physical barriers such as cones, can be hard to find storage locations for. Caution tape, on the other hand, can easily fit into spill kits and be used to hang across doors as a physical barrier.
Consider the efficacy of the tool used to restrict access to hazardous material spills at your facility, before you need to use it.
