Smoking Controls and Designated Smoking Areas

Expert-reviewed Updated: 2026-09-01 Expert-reviewed: 2026-09-04 (Guido Hesse, Hesse Group Holding AG) Version 0.1.0

Smoking controls and designated smoking areas are organisational measures by which operations exclude uncontrolled ignition sources from smoking in fire-hazardous areas while meeting statutory requirements on protection from passive smoking.

Smoking as an ignition source

Discarded cigarettes and ash residues are among the most frequent uncontrolled ignition sources in industrial and warehouse operations, especially near storage and waste areas, fuelling points, and zones with combustible dust or vapours. Unlike hot work, smoking is typically unsupervised, so a smouldering fire is often only discovered as open flame hours later.

Implementation on site

An effective policy sets out written no-smoking rules for production, storage and hazardous materials areas, provides structurally and technically suitable smoking areas with non-combustible ash receptacles, and embeds the rules in house rules and contractor inductions. In Switzerland, smoking is already prohibited by law in enclosed rooms serving multiple people as a workplace; site rules for fire-hazardous areas typically go further and also cover outdoor zones next to storage areas and buildings.

Relevance for insurance

Property insurers frequently require comprehensive smoking bans as a policy condition where combustible loading or an explosible atmosphere is elevated. Enforcement and monitoring of the rule – for example through self-inspections – are standard checkpoints of every risk survey.
