Smoking in airplane lavatories is strictly forbidden and carries heavy penalties. However, international civil aviation regulations (such as the FAA) mandate that an ashtray must be present there.
- The logic is this: If someone defies the ban and smokes secretly, an ashtray is provided so they don’t panic and throw the butt into the trash bin (among paper towels).
- A cigarette butt thrown into a trash bin can set the entire plane on fire, whereas putting it in an ashtray is merely a rule violation. [1][3]
- ‘Hybrid’ Units in Malls and Enclosed Areas
The modern units you see inside malls are often not just ashtrays, but part of ‘Zero Waste’ or ‘General Waste’ stations.
- Visual Design: Manufacturers produce these units as standard with sand-topped or metal-grated (ashtray function) lids. Mall managements often continue to use the standard model instead of replacing it just because ‘smoking is banned inside.’
- Transition Zones: These units are generally placed at entrances or ‘transition’ points near outdoor areas. The goal is to provide a safe place for someone entering the building to extinguish their cigarette at the last moment.
- The Link Between ‘Airflow’ and Fire Spread
The ‘sound frequency’ or rather the airflow/draft issue you mentioned earlier comes into play here. Enclosed spaces (like mall corridors) have powerful ventilation systems.
- If someone violates the ban and tosses a butt into a regular trash can in a closed area, the airflow created by the ventilation rapidly fans that ember into a flame.
- Those modern ashtrays in ‘prohibited areas’ serve as a passive line of defense that prevents such an act of negligence from burning down the building.
- The Notre Dame and Restoration Site Contradiction
As you noted, the cathedral itself is not a smoking area. However, the presence of these units at the restoration site (on the scaffolding) might have been intended to prevent a fire, assuming that workers might smoke ‘regardless of the ban.’ The catastrophe occurred when people went outside these controlled points (by tossing a butt directly onto 1,000-year-old timber). [7][8]
In summary: Those ashtrays are there not to ‘encourage’ smoking, but to prevent someone who breaks the rules from accidentally ‘blowing up’ the building. Security experts say ‘Humans make mistakes,’ and they try to mitigate the cost of that mistake (a misplaced cigarette butt) by using ashtrays.
Do you think the presence of these units in prohibited areas encourages people to smoke, or does it truly provide a layer of security?”
