DOT specification cylinder and is marked, labeled, filled, and 
maintained as prescribed by this subchapter;
    (2) Each battery used is of the nonspillable type;
    (3) The unit is constructed so valves, fittings, and gauges are 
protected from damage;
    (4) The pilot-in-command is advised when the unit is on board, and 
when it is intended for use;
    (5) The unit is accompanied by a person qualified to operate it;
    (6) The unit is secured in the aircraft in a manner that does not 
restrict access to or use of any required emergency or regular exit or 
of the aisle in the passenger compartment; and,
    (7) Smoking within 3 m (10 feet) of the unit is prohibited.
    (f) Hazardous materials which are loaded and carried on or in cargo 
only aircraft, and which are to be dispensed or expended during flight 
for weather control, environmental restoration or protection, forest 
preservation and protection, fire fighting and prevention, flood 
control, or avalanche control purposes, when the following requirements 
are met:
    (1) Operations may not be conducted over densely populated areas, in 
a congested airway, or near any airport where carrier passenger 
operations are conducted.
    (2) Each operator shall prepare and keep current a manual containing 
operational guidelines and handling procedures, for the use and guidance 
of flight, maintenance, and ground personnel concerned in the dispensing 
or expending of hazardous materials. The manual must be approved by the 
FAA Principal Operations Inspector assigned to the operator.
    (3) No person other than a required flight crewmember, FAA 
inspector, or person necessary for handling or dispensing the hazardous 
material may be carried on the aircraft.
    (4) The operator of the aircraft must have advance permission from 
the owner of any airport to be used for the dispensing or expending 
operation.
    (5) When dynamite and blasting caps are carried for avalanche 
control flights, the explosives must be handled by, and at all times be 
under the control of, a qualified blaster. When required by a State or 
local authority, the blaster must be licensed and the State or local 
authority must be identified in writing to the FAA Principal Operations 
Inspector assigned to the operator.
