How Krajowa Izba Kominiarzy Made Saint Florian a Carbon Monoxide Test
"A Sign From Saint Florian" is a 2019 public service campaign created by Grey Group Poland for Krajowa Izba Kominiarzy, Poland's national chamber of chimney sweeps, using printed images of Saint Florian placed against household ventilation inlets to test airflow and alert residents to potential carbon monoxide risk.
Krajowa Izba Kominiarzy launched the campaign in April 2019 in Poland, operating across the film medium and the broader public interest category. The campaign's central mechanic is both devotional and diagnostic. Saint Florian is the patron saint of chimney sweeps — as well as a figure associated with protection from fire — making his image a culturally resonant object in Polish households. Grey Group Poland engineered a dual function for that image: when held against a ventilation inlet, the printed card acts as a rudimentary airflow indicator. If the card adheres to the surface, airflow is present and ventilation is functioning. If it falls away, the blockage signals a potential carbon monoxide hazard requiring professional chimney-sweep inspection.
According to adsoftheworld.com, the campaign ran for more than fourteen months and distributed almost thirty million instruction cards across Poland over that period. In the Polish context, where household heating systems — including coal-fired stoves, wood-burning fireplaces, and gas boilers — place ventilation maintenance at the centre of domestic safety, the campaign addresses a genuine and recurring public health risk. Carbon monoxide poisoning remains a leading cause of non-fire-related fatal poisoning in Poland, according to reporting by Little Black Book. By anchoring the safety message to a recognisable religious and professional icon, Krajowa Izba Kominiarzy and Grey Group Poland created a campaign object that could move through homes, churches, and community gatherings without feeling like institutional government communication. The Clapboard Score for this campaign is 76/100.
Krajowa Izba Kominiarzy occupies a specific institutional position in Poland's domestic safety landscape. The organisation is the national professional body for chimney sweeps, responsible for both trade standards and public education around ventilation, fire prevention, and carbon monoxide awareness. Its 2019 campaign did not emerge in isolation. According to adsoftheworld.com, the chamber had distributed twenty-eight million leaflets through a Grey-created carbon monoxide campaign the previous year, in 2018, working through partner brands and retail environments. "A Sign From Saint Florian" represents a strategic evolution of that distribution model — moving from passive information leaflet to interactive diagnostic tool.
The strategic insight is rooted in the cultural calendar. Chimney Sweeps' Day in Poland falls on 4 May, as documented by adsoftheworld.com, and Krajowa Izba Kominiarzy held its national professional celebration in Olsztyn between 22 and 24 May 2019, according to adsoftheworld.com. The April launch of the campaign positioned it directly ahead of this professional and public moment, maximising the window during which chimney-sweep services are top of mind for Polish homeowners transitioning out of the heating season.
In the broader Polish public safety communications space, Krajowa Izba Kominiarzy operates alongside the National Fire Service of Poland, which serves as an official authority and partner on fire and carbon monoxide safety, as noted by Izbakominiarzy Pl. Where the National Fire Service's communications tend toward emergency-response messaging, the Krajowa Izba Kominiarzy campaign positions the chimney sweep as a preventive professional — a distinction that differentiates the chamber's public interest work from reactive government safety advertising. The 2016 "Zaproś kominiarza" campaign, which used press, television, trade fairs, and written communications to public authorities across Poland, according to izbakominiarzy.pl, established the chamber's precedent for multi-channel public engagement. The 2019 campaign narrows that approach to a single, high-utility physical object with a film component driving awareness of its use.
Grey Group Poland built the campaign's creative logic around a single, transferable object. The printed image of Saint Florian — patron saint of chimney sweeps, firefighters, and metalworkers, as documented by adsoftheworld.com — functions simultaneously as a devotional keepsake and a ventilation diagnostic card. This dual identity is not incidental; it is the entire creative proposition. By making the test object something a Polish household might already choose to display or preserve, the campaign removes the friction that typically prevents safety tool adoption.
The film component, catalogued in the Clapboard archive and on adsoftheworld.com as the campaign's primary media asset, demonstrates the mechanism in action: a resident holds the Saint Florian card against a ventilation inlet, observes whether it adheres or falls, and understands the result without technical knowledge. The instruction requires no literacy beyond the visual demonstration, which extends its utility across age groups and educational backgrounds in Poland.
According to lbbonline.com, Marcin Ziombski is identified in connection with the campaign's creative development at Grey Group Poland. The production approach prioritises the instructional clarity of the demonstration over aesthetic complexity, consistent with the public service category's demand for immediate comprehension over branded entertainment. The decision to use Saint Florian specifically — rather than a generic safety mascot or a medical-style diagram — reflects a considered understanding of how Catholic iconography functions in everyday Polish domestic life. The card does not need to be explained as a safety device because it arrives framed as something already welcome in the home. That cultural encoding is the campaign's primary creative achievement, and it is what distinguishes the work from conventional carbon monoxide awareness advertising produced elsewhere in Europe.
No verified independent performance data for "A Sign From Saint Florian" is publicly available in the form of audience recall scores, chimney inspection uplift figures, or carbon monoxide incident reduction statistics attributable to the campaign. What the public record does document is distribution scale. According to adsoftheworld.com, the campaign distributed almost thirty million instruction cards across Poland over a period of more than fourteen months — a figure that, set against Poland's population of approximately thirty-eight million, as recorded by official Polish national statistics, suggests near-universal theoretical household reach if distribution was demographically targeted.
That scale becomes more legible when placed against the prior year's precedent. The 2018 Grey-created carbon monoxide campaign for Krajowa Izba Kominiarzy had distributed twenty-eight million leaflets through partner brands and retail environments, according to adsoftheworld.com. The 2019 campaign marginally exceeded that distribution volume while replacing a passive leaflet with an active testing device — a structural improvement in utility that the distribution figures alone do not capture but which the campaign's design logic makes evident.
From a structural effectiveness standpoint, the campaign resolves three common barriers to public safety communication in Poland and comparable markets: it provides an immediate, self-administered action rather than a deferred call to professional services; it uses a culturally embedded object to lower resistance to engagement; and it connects the test result directly to the professional service — chimney sweep inspection — that Krajowa Izba Kominiarzy exists to promote. The film medium asset documents and amplifies the mechanic rather than carrying the safety message independently. The campaign's design means its primary medium is the card itself, distributed at scale, with film serving as demonstration and reach driver.
"A Sign From Saint Florian" is a 2019 public service campaign created by Grey Group Poland for Krajowa Izba Kominiarzy. It distributed printed images of Saint Florian that doubled as household ventilation tests, alerting Polish residents to potential carbon monoxide risk when airflow was insufficient to hold the card against a ventilation inlet.
Saint Florian is the patron saint of chimney sweeps in Poland, as documented by adsoftheworld.com. Using his image made the ventilation test card a culturally familiar object in Polish homes, lowering resistance to engagement and allowing the safety tool to circulate through domestic, religious, and community settings without appearing as institutional government messaging.
According to adsoftheworld.com, almost thirty million Saint Florian instruction cards were distributed across Poland over the campaign's run of more than fourteen months. This marginally exceeded the twenty-eight million leaflets distributed through the chamber's previous Grey-created carbon monoxide campaign in 2018, also per adsoftheworld.com.
The printed Saint Florian card is held against a household ventilation inlet. If sufficient airflow exists, the card adheres to the surface, indicating functioning ventilation. If the card falls away, the absence of airflow signals a potential blockage and possible carbon monoxide risk, prompting the resident to contact a professional chimney sweep for inspection.
Krajowa Izba Kominiarzy published the campaign in April 2019 in Poland, according to adsoftheworld.com and Clapboard's archive. The campaign ran for more than fourteen months in total, as reported by adsoftheworld.com, with the April launch timed directly ahead of Chimney Sweeps' Day in Poland on 4 May.
Grey Group Poland created "A Sign From Saint Florian" for Krajowa Izba Kominiarzy, Poland's national chamber of chimney sweeps.
