Both formats can meet the professional requirements. The deciding factors are group size, workplace risks, organisation and the need for a direct connection to the site.

The correct provision follows from the risk assessment, fire classes, floor area, extinguishing ratings and the specific work areas.

Fire safety assistants are not emergency responders. An extinguishing attempt is reasonable only when the situation is manageable, the escape route is clear and there is no personal risk.

From the safety briefing to each participant’s extinguishing attempt, this is how theory becomes reliable practical competence.

What ASR A2.2 and the DGUV say about refresher intervals, and when an earlier refresher is useful or required.

Metal fires behave differently from ordinary fires. Learn why water and CO₂ can be dangerous and which extinguishing agent is suitable for Class D fires.

Portable heaters can warm rooms quickly, but they also involve high electrical loads, hot surfaces and, with unsuitable fuels, an invisible carbon monoxide hazard.

Lithium-ion batteries are reliable when used correctly. Damage, heat, unsuitable charging or technical defects can, however, cause a fire that is difficult to control.

The number of certificates is not what matters. Reliable availability of qualified people on every shift and in every relevant area is decisive.

Electric blankets provide targeted warmth, but damaged cables, incorrect use or heat build-up can cause fires and burns.

Fire classes classify burning materials. They help identify a suitable extinguishing agent, but they do not by themselves determine whether its use is safe.

English-speaking employees must genuinely understand the content, workplace procedures and limits of fire-fighting.

The DGUV Workplace Barometer 2026 shows how employees assess their organisations’ crisis preparedness and where action is needed, particularly in fire safety.

Extinguishing effect alone is not enough. Fire class, room, people, equipment and potential consequential damage determine the correct choice.

Training extinguishers must be safe, operational and matched to the operating principles of the equipment available at the workplace.
