4.3.8 The fuel tank(s) shall be located for protection against collision damage, and so that any overflow during tilling, or any leakage from the tank, fuel lines, or fittings, will not impinge on engines exhaust system. electncal system, or other ignition sources, or enter the driver’s cabin.
4.3.9 Tow hooks shall be installed on the chassis structure, with at least one at the front and one at the rear. The tow hooks shall be usable with the operators’ cabin or basket in any position.
4.3.10 Storage electrical batteries shall be of the heavy duty type, and alternators shall be dimensioned bearing In mind that dc-icing units often operates in engine Idle condition hut with all electrical consumers switched on.
4.4 Aerial device
4.4.1 The de-icer shall provide an aerial device including a supporting boom, to which shall be attached either an enclosed operator’s cabin fitted with windshield wipers and a defroster/heater system. or (see Note in the Introduction) an open operator’s basket entirely surrounded by full guard-rails up to a height of at least 1,1 m (43 in) over its floor. Cabin or basket shall be rated for a minimum of two persons (minimum load capacity of 204 kgJ450 Ib). to provide for operators training and possible visual dc-Icing control by a separate qualified person. Where these objectives are not retained, a cabin or basket intended for a single person shall be rated for a minimum load capacity of 160 kg (3S0 Ib).
4.4.2 The operator’s cabin or basket and its supporting boom shall be designed to position an operator to effectively apply de-icingjanti-iclng fluid to the upper areas of aircraft control surfaces, wings, vertical and horizontal stabilizers, and fuselage. Consideration shall be given to the height of these surfaces on aircraft types Intended to be serviced while designing or selecting any de-icer type.
4.4.3 The operator’s cabin or basket shall have a self-adjusting mechanism to maintain a vertical operating attitude for all boom positions.
4.4.4 The operator’s cabin or basket shall allow safe access from the ground in the stowed position, and provide for safe and easy entry and exit The cabin door or basket gate shall not fold or open outwards. and shall be constructed to either be automatically self-closing and latching, or boom movements. including lifting from the stowed position, be prohibited unless the cabin door or basket gate is closed and fully latched. Where this Is ensured by interlocking, the corresponding safety device shall ensure a pertormance level c in accordance with ISO 13849-1.
4.4.5 The design of the operator’s cabin shall be such as to strictly minimize, in as much as possible, entry of de.iclng/antl.icing fluids aerosols (with windows closed). See Annax A for toxicological hazards. The cabin shall, as a minimum, be equipped with a mechanical filter on the air intake, for removal of aerosols produced.
4.4.6 The cabin’s inner operator envelope shall take into account the likeliness of operators wearing heavy winter clothing, boots, and gloves. The cabin, unless fitted with seats with safety belts for all occupants, or basket shall be fitted with harness anchorage points for personal protective equipment (PPE) harness(es). If provided, operator seat(s) shall be fitted with automotive type 3 poInts inertia reel safety belts.
4.4.7 (A) lighting projector(s), adjustable from the operator’s cabin or basket, shall be provided to illuminate the spraying area for night operation. The minimum total luminous flux shall be 1000 Im (equivalent to approximately 100 W incandescent bmp power).
4.4.8 The structural and fatigue strength of the cabin or basket, its attachment to the boom, the boom itself, and Its attachment to the chassis shall be in accordance with the requirements of 4.12 and 4.1.3. The aerial device, including the cabin, the boom, and its attachment to the chassis shall be designed in such a manner that periodic structural inspection can readily be carried out without major disassembly.
