Driven (on) the employment place is the generic term of the task forces of fire-brigade, emergency service, THW and other relief organizations for the variety of harmful influences, which can occur in their employment places. In order to protect itself against them, they must know these dangers, their effects as well as means for their defense. For high-level personnel this is particularly important, in order to make the employment-tactically correct decisions.
Since the individual dangers can be extensive and difficult-to-understand, the task forces avail themselves the danger pattern, a noticing rule (4A-1C-4E-Regel), which designates the most important danger emphasis. Particularly in the guidance procedure by systematic going through of all single steps it is guaranteed that no danger became to ignore and the employment-tactically correct decisions is met.
| A | Breath poisons |
| A | Propagation |
| A | Fear reaction/panic |
| A | Atomic dangers/ionizing radiation |
| C | Chemical dangers |
| E | Explosion |
| E | Illness/injury |
| E | Electricity |
| E | Collapse |
Depending upon literature the 4A-1C-4E-Regel will through add of
to the 5A-1B-1C-5E-Regel extends. That is to strengthen the attention of these dangers in the context of the guidance procedure.
Advocates of the simpler form crash already contained in collapse, it can finally break not only things over someone, but also under someone away, the basis of biological dangers are in the long run also only hydrocarbon connections and become usually under chemical dangers, because of the similar employment-tactical procedure, and/or illness, the consequences because of, checked off, drowning falls then into the category illness/injury and water dangers earliest to propagation.
Apart from the dangers contained in the patterns exist further dangers, which are not transferred however due to missing general validity to the pattern. Examples are the ways to the fire station, travels with separating and rights of way, dangers those from special devices go out (power saw, Trennschleifer, hydraulic evacuation equipment," ) as well as dangers in the traffic.
Not all dangers concern humans, animals, environment and real values equally. For the purposes of the guidance procedure to this matrix additionally crew and equipment are taken up.
| Humans | Animals | Environment | Real values | Crew | Equipment | |

| Fear reaction | ||||||

| Attack | Eliminate the cause of the danger. |
| Defense | Protection of the threatened property by abolition of the influence of the danger. |
| Rescue | Remove the threatened property from the sphere of influence of the danger. |
| Retreat | Task of the threatened property. |
Poisons, which can be inkorporiert by the respiration. Although already into "chemical dangers "contain, breath poisons are again specified in the noticing pattern, in order to consider to its importance (frequency of the occurrence, high endangerment, simple protection). Breath poisons can endanger respiration of task forces also otherwise (e.g. contact contacts, etching action) beside the incorporation way. Example: Toxic ones combustible gas-see breath poison.
Instinct-steered behavior of humans, animals and task forces in different development example: To jump from the burning house into the jump rescuer or into the straight in the structure, not developed yet, present leader-see panic.
All forms of the enlargement of an employment situation, concerning both spatial enlargement and enlargement of the circle that concerning example: Spread the fire to an auxiliary building, contamination kidnapping in the GABC employment.
Harmful influences by ionizing radiation from radioactive sources or technical mechanisms such as x-ray units, particle accelerator example: To traffic accident with participation of a transport of radioactive preparations for medicine-see danger property.
From chemical characteristics resulting dangers such as and poisoning example: To reaction of household cleaners with education of chlorine-gas-see danger property.
Generally each form of illness, particularly trauma tables injuries by accidents and infection example: To employment in a hospital, endangerment by possibly infectious material-see danger property, first assistance.
Endangerment by pieces of throw and pressure wave with different event example: To flywheel explosion after mechanical defect, after fire-effect-see danger property, explosive, BLEVE, explosion prevention
Endangerment by rubble parts, crash of task force example: By fire effect weakened structural design leads to the destruction building-sees structural design, crash (accident).
Harmful influences on the human body by current flow, fire risk example: Employments within the range of overhead lines course-see electricity, electrical accident
