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. 10-7
