Under what circumstances can a fire detail consist of personnel from less than one fire company?

A fire detail being composed of personnel from less than one fire company is allowed primarily under extenuating circumstances. This means that when situations arise that are unusual or beyond the standard operational capacity, such as a sudden need for coverage due to an unexpected absence of personnel, or during emergencies where full staffing is not attainable, it becomes permissible to have a detail that does not meet the usual company composition.

In contrast, the other scenarios presented may not typically justify a reduction in staffing to less than a full fire company. Scheduled maintenance is usually planned and should be covered by the full staffing of a company. Training activities generally require full participation from the personnel to ensure proper training and safety standards. Public events typically also necessitate a full company presence to ensure adequate safety protocols and response capabilities. Therefore, the flexibility to operate with less than one full fire company is properly reserved for cases that are deemed truly exceptional or unavoidable.
