GENERAL PRECAUTIONS AND WARNINGS
The SEA-4500 is intended for use only as an emergency device
to assist a crew member 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-4500, it is important to receive in-water
survival training which simulates an emergency egress situation.
You must also learn basic principles and techniques for breathing
compressed air underwater. Use of the SEA-4500 without proper
training is dangerous and can result in serious injury or death.
Visual inspection and factory prescribed service for the SEA-4500
must be performed at least once every two years by a factory trained
and qualified service technician. Repair, service and visual inspection
must not be attempted by untrained or unqualified personnel.
DO NOT attempt to overfill the SEA-4500 beyond 4500 PSI / 310
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-4500 if it has been exposed to extreme
heat exceeding 250º F / 121º C or open flame. Instead, discharge
the cylinder completely and return it to a qualified technician for
inspection and possible hydrostatic testing.
The SEA-4500 is designated compatible for use only with normal,
atmospheric, compressed air (21% oxygen and 79% nitrogen by
volume). DO NOT attempt 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.
