Cessna 190 and 310 Battery Positions

Cessna 190 and 310 Battery Positions

<HTML>I'm a Volunteer firefighter in the area whereI live and need to know the battery positions would be on these aircraft for the safety course that I am doing to teach other firefighters where the Battery cables are on these aircraft. These are cut by firefighters in order for it to be safe to enter the aircraft so that lives may be saved.</HTML>

Re: Cessna 190 and 310 Battery Positions

<HTML>There is no reason to have to cut any battery cables on any aircraft in order to evacuate persons from that aircraft. This misconception is a throw-back to the early days of turbine powered aircraft that had nicad batteries subject to "thermal runaway", a hazard not commonly seen anymore due to subsequent aircraft modification. Cessna 190 and 310 aircraft do not use nicad batteries. Aircraft batteries are contained within battery boxes located in non-passenger areas (forward of firewalls, aft of cabin bulkheads, or in dedicated wing-lockers,...and in very few cases in ejection-compartments below cockpit flooring) and are always vented to atmosphere. If you arrive at the scene of an aircraft emergency do not waste time looking for battery location. Remove the occupants away from the aircraft and apply chemical fire suppressant commensurate with any other heavily fueled vehicle. I do not advise you to alter the aircraft in any unnecessary manner without the permission of the pilot or owner, in which case you may obtain battery information from them. Any cutting of aircraft structures (other than for fuselage/passenger-cabin access) carries the risk of actually increasing danger of hydraulic/fuel/electrical spillage and fire.</HTML>

Re: Cessna 190 and 310 Battery Positions

<HTML>Thanks for the response, the problem is not that firefighters are afraid of runaway aircraft, but the fact that local bylaws require us to do so. They were put in place due to incidents on various vehicles actually starting while on fire. I realize that cutting aircraft apart is dangerous, I am a Aircraft Mechanic myself, but due to these laws and the fact that as firemen we can be held liable and sued if we do not follow local laws. so any info on these locations would be helpful.
