WARNING
Never use aerosol-propelled sprays near the
face port of any Kirby Morgan diving helmet.
The propellant used in these aerosols can
invisibly damage the face port and cause it
to shatter on impact from any strong blow. If
the face port fails underwater, injury or death
may result.

2.5.2 Minimum Operating Temperature
The KM-77 can be used in waters at water tem-
peratures as low as 34 degrees Fahrenheit (1 degree
Celsius) without the use of a hot water shroud and
hot water to prevent freezing. However it is strongly
recommended that the hot water shroud be used for
the comfort of the diver. At the time of this writing a
specific part number hot water shroud is not available
for the KM-77 however work is underway to produce
one. The the standard shroud PN# 525-100 can be
modified to work. for more information contact Dive
Lab Inc. www.divelab.com
Without a hot water shroud, the diver may be subject
to hypothermia due to cold gas inspiration tempera-
tures. Kirby Morgan makes no physiological rec-
ommendations regarding minimum safe operating
temperatures for divers using this helmet.
WARNING
Diving in cold water, i.e., at temperatures
below 50 degrees F, may subject the diver
to severe respiratory heat loss. This may
lead to a decrease in body core temperature
also known as "hypothermia." Hypothermia
is extremely dangerous and can lead to a
loss of reasoning ability, decreased manual
dexterity, uncontrollable shivering, uncon-
sciousness, and death.
