placement3. of FE is to be used and placed at a visible place. 4. FE are placed in areas with high probability of fires 5. Portable FE are placed on the wall, so that the handle of EF was up to 1,5m
above the ground 6. FE on the floor must be prevented from falling 7. FE in vehicles are placed not to endanger personal safety
