4. Add any notes on conditions in the space that
increase heat.
5. When results show that personnel will be
exposed to heat stress in less than 4 hours, send the
results to the CO promptly.
When stay time is greater than the duration of a
watch or work period (normally 4 hours), conduct the
next survey during the hottest time of the day. If the stay
time is greater than the normal watch or work period at
the hottest time of day, then you need only two surveys
each day.
When stay time is less than the watch or work
period, conduct a survey at least once per stay-time
period. If you conduct more than one, conduct them at
about equal intervals. In these cases, be sure to record
the outside weather dry-bulb and wet-bulb
temperatures. Compare those temperatures with those
at work or watch stations to learn how much moisture
is being added to the space due to steam and/or water
leaks.
RECOVERY TIME
When personnel leave a heat stress environment
because they have reached or exceeded their stay time,
they should stay in a cool, dry area that will help a rapid
recovery. The length of recovery time in a cooled space
should be twice the exposure time, or 4 hours, whichever
is less. If there is evidence of cumulative fatigue, the
recovery time should be longer. When personnel who
complete recovery periods are often unable to carry out
normal work, or have frequent health disorders, they
should be sent to the ship’s medical department for
evaluation.
PRECAUTIONS AGAINST HEAT STRESS
Learn the symptoms of heat injury and take action
if you see the symptoms in yourself or others. Get
treatment in sickbay for heat rash or heat cramps. Report
victims of heat exhaustion for treatment. Heatstroke is
a medical emergency; cool the victim by any possible
means and get medical help immediately. If you are
often exposed to heat stress environments, take the
following precautions:
. Eat three well-balanced meals daily.
. Drink plenty of water.
. Do NOT take salt tablets.
Do NOT drink commercial electrolyte
supplements instead of water.
Get at least 6 hours continuous sleep every 24
hours.
Do NOT wear starched clothing.
Wear clean clothing made of at least 35 percent
cotton (more natural fiber content means more
evaporation).
SIGHT CONSERVATION PROGRAM
Navy policy requires eye protection for personnel
who work in or visit areas or operations where there is
danger of injury to the eyes. This section will give you
an overview of the sight conservation program that
implements the policy. Refer to instructions for more
detailed information.
PROGRAM ELEMENTS
Each command will implement a sight conservation
program that will include at least the following
elements:
l
l
l
l
l
l
l
Use zone inspections and industrial hygiene
survey results to designate eye hazardous areas,
processes, and operations.
Implement a ship’s vision screening program
using shore-based medical facilities.
Maintain sight protection equipment.
Establish procedures for the use of temporary eye
wear.
Establish emergency eyewash facilities.
Follow approved safety standards that require
protective eye wear.
Establish training and program enforcement
procedures.
EYE HAZARD AREAS
Responsible personnel will conduct a survey of all
work areas, processes, and operations to identify those
that may be hazardous to the eyes. This survey will be
part of the workplace inspection and industrial hygiene
survey. The safety officer will keep a list of all areas,
processes, and operations that require eye protection.
