SEA USER'S MANUAL
General precautions & Warnings
The SEA is intended for use only as an emergency device to assist
a crewmember or passenger in making an emergency egress from a
submerged aircraft. Due to its limited air volume, it is not intended for use
while scuba diving, or egressing from depths greater than 45 ft/ 13.5 m.
Before using the SEA, it is important to receive in-water survival train-
ing which simulates an emergency egress situation. You must also learn
basic principals and techniques for breathing compressed air underwater.
Use of the SEA without proper training is dangerous and can result in
serious injury or death.
Visual inspection and factory prescribed service for the SEA must be
performed at least once every two years by a factory trained and quali-
fied service technician. Repair, service, and visual inspection must not be
attempted by untrained or unqualified personnel.
DO NOT attempt to overfill the SEA beyond 3,000 PSI/ 206 BAR at 70ºF/
21ºC. Doing so may seriously weaken the cylinder and cause it to rupture,
resulting in serious injury or death.
DO NOT fill or use the SEA if it has been exposed to extreme heat
exceeding 250°F / 121ºC, or open flame. Instead, discharge the cylinder
completely and return it to a qualified technician for inspection and
possible hydrostatic testing.
The SEA is designated compatible for use only with normal, atmospheric,
compressed air (21% oxygen and 79% nitrogen by volume). DO NOT at-
tempt to fill with other gases, including pure oxygen, or air which has been
enriched with oxygen exceeding 21% in content. Failure to observe this
warning may result in serious injury or death due to fire and explosion, or
the serious deterioration and failure of the equipment.
DO NOT apply any type of petroleum-based lubricant, such as household
oil or motor oil to any part of the SEA. The SEA does not require any lubri-
cation under normal circumstances, except that which is performed during
annual inspection and service by a factory trained service technician.
DO NOT apply any type of aerosol spray to the SEA. Doing so may cause
permanent damage to certain plastic components, including the second
stage housing.
During training exercises, it is important to ensure that the SEA is always
pressurized whenever it is submerged in order to prevent the entrance of
water into the system. Whenever the system has been completely emptied
of air underwater, it is important to return the SEA as soon as possible
to a qualified technician for visual inspection and any necessary service
before attempting to refill it.
It is important to fill the SEA only with dry, filtered air with a water vapor
content that does not exceed -65°F / -53ºC dewpoint. Excess water vapor
in the air can cause ice to form inside the SEA and interfere with the
operation of the system at colder temperatures.
