Where should "No Smoking" signs be located?

The placement of "No Smoking" signs is particularly critical in contexts where hazardous materials are present. These materials can be highly flammable or sensitive to ignition sources, and smoking poses a significant risk in such areas. By placing "No Smoking" signs specifically in rooms or areas where hazardous materials are stored or used, it effectively communicates the potential dangers and helps to mitigate fire hazards. This strategic placement not only fosters a safer environment but also complies with regulations that aim to prevent accidents and ensure the safety of all individuals in the facility.

Choosing to place signs in only certain locations, such as exits or outside the building, would not adequately address the specific risks associated with hazardous materials, nor would it promote comprehensive safety practices throughout the facility. Thus, areas with dangerous substances should be prioritized for "No Smoking" signage to enhance safety awareness and compliance among personnel and visitors.
