The maximum pressure in hose lines should be limited to 250 psi. Only emergency needs which allow for no other corrective action permit the use of higher pump pressures. Pressures in excess of 250 psi can only be ordered by who?

Company officers may order the stretching of 1 3/4 inch hose at fires as the initial line if its use is compatible with fire conditions and the extinguishing capability of the 1 3/4 inch hose is weighed against what?
• The fire’s magnitude, location and potential for spread.• The occupancy of the structure and possible life hazard.• The advantages to be gained by an increased speed in stretching and the increased mobility of the line, versus the need for a greater water delivery rate to control the fire.LO LAMPL- Life HazzardO- OccupancyL- Location fireA- Advantages speed and mobilityM- magnitude of fireP- potential for spread7.6.2 GS
The use of 1 3/4 inch hose would be inappropriate and a company officer should not order it stretched if any of the following conditions exist:?
• The line is expected to be used from a purely defensive position.• An advanced fire on arrival.• A large volume of water is required to cool a superheated fire area.• A large body of fire in a large uncompartmented area.• When the officer cannot determine the size or extent of the fire or fire area.DALLASD- Defensive purleyA- Advanced fire on arrivalL- Large volume water neededL- Large body fire in LARGE uncommpartmented areaA- Area , size or extent fire not determinedS- Standpipe operation7.6.3 GS
