What locations should "No Smoking" signs be posted near?

The correct choice is to post "No Smoking" signs near hazardous material storage areas because smoking poses significant fire and health risks in environments where flammable or toxic materials are stored. The presence of such materials creates an increased likelihood of ignition and, consequently, severe fire hazards. Therefore, it's essential to clearly communicate the prohibition of smoking in these areas to ensure the safety of all personnel and prevent potential accidents or emergencies.

In contrast, while signs might be warranted near offices, restrooms, or break rooms, the urgency and necessity of "No Smoking" signage are paramount in locations that store hazardous materials. The other environments mentioned generally do not carry the same level of risk in terms of fire hazards as those associated with hazardous materials. Hence, the focus should primarily be on maintaining safety in high-risk areas.
