 SUBJ: HEAT INJURIES
 A. COAST GUARD CUTTER HEAT STRESS PROGRAM, COMDTINST  M6260.17 

 
 1. SEVERAL MISHAPS RELATED TO HEAT INJURIES HAVE  BEEN REPORTED IN THE PAST MONTH INCLUDING A NEAR FATAL CASE OF HEAT  STROKE. UNIT COMMANDERS ARE RESPONSIBLE FOR ENSURING THAT THE  PREVENTIVE  MEASURES IN THE HEAT STRESS PROGRAM ARE FOLLOWED PER   REFERENCE "A". 

 
 UNIT COMMANDERS SHOULD CONSIDER HAVING EITHER A  SAFETY STAND DOWN  OR ALL HANDS MEETING TO DISCUSS HEAT INJURIES AND THEIR PREVENTION. 

 
 UNIT COMMANDERS SHALL REFER TO THE WORK/REST  SCHEDULE TABLE NOTED  IN HTTP://WWW.USCG.MIL/HQ/G-W/G-WK/WKS/INDEX.HTM   UNDER "HOT TOPICS" AS WELL AS THE PREVENTIVE MEASURES NOTED   BELOW TO ESTABLISH
 A SAFER WORKING ENVIRONMENT. 

 
 2. IT IS VERY IMPORTANT THAT ALL COAST GUARD  PERSONNEL MAINTAIN A  HIGH LEVEL OF AWARENESS OF THE POTENTIAL FOR SERIOUS   ILLNESS OR  DEATH DUE TO EXPOSURE TO HIGH TEMPERATURES. THE  MAJOR CATEGORIES OF HEAT INJURY ARE NOTED BELOW: 

 
 A. HEAT STROKE. 
 
 1. HEAT STROKE IS CONSIDERED A MEDICAL EMERGENCY  HICH IS CAUSED  BY THE SHUTDOWN OF THE BODYS REGULATORY
 SYSTEM. THIS RESULTS  IN A SIGNIFICANT RISE IN THE BODYS CORE TEMPERATURE   AND BEGINS TO  ADVERSELY AFFECT THE BODYS MAJOR ORGAN SYSTEMS. IF   UNTREATED, HEAT STROKE MAY RESULT IN DEATH. SIGNS INCLUDE THE FOLLOWING: ALTERED MENTAL STATUS, HOT DRY SKIN, DEEP AND RAPID BREATHING, RAPID PULSE, AND HIGH BODY TEMPERATURE. 
 
 2. PREVENTION. IMPLEMENT AN APPROPRIATE WORK/REST SCHEDULE TO PREVENT HEAT RELATED INJURIES. DRINK ADEQUATE
 AMOUNTS OF WATER THROUGHOUT THE WORK PERIOD. PER THE INSTITUTE OF MEDICINE, ADEQUATE FLUID INTAKE IS PPROXIMATELY 10 CUPS (80 OUNCES) FOR WOMEN TO 13 CUPS (100 OUNCES) FOR MEN OF WATER OR OTHER NON CAFFEINATED BEVERAGES A DAY. THE NEED FOR FLUIDS VARIES DEPENDING ON ACTIVITY LEVEL, CLIMATE AND TEMPERATURE. DRINK
 ADEQUATE AMOUNTS OF FLUIDS THE DAY BEFORE A PLANNED WORK PERIOD WHERE PHYSICAL ACTIVITY IS EXPECTED UNDER HEAT STRESS CONDITIONS. ALCOHOL CONSUMPTION SHOULD BE AVOIDED DURING THESE PERIODS.  EAT WELL- BALANCED MEALS BEFORE AND DURING THE WORK CYCLE AND GET A MINIMUM OF EIGHT HOURS OF SLEEP THE NIGHT BEFORE. ACCLIMATIZATION TO THE ENVIRONMENT IS IMPORTANT FOR THOSE WITH PRIOR   HISTORY OF HEAT RELATED INJURIES. 
 
 3. TREATMENT. SEEK IMMEDIATE EMERGENCY MEDICAL ASSISTANCE AND MOVE THE VICTIM TO A COOL ENVIRONMENT. REMOVE ANY CONSTRICTED CLOTHING TO COOL THE SKIN. APPLY COOL (NOT COLD)   WATER ON THE VICTIM BY IMMERSION IN A TUB, PLACING THEM IN A SHOWER, SPRAYING WATER ON THE VICTIM THROUGH A HOSE, OR SPONGING THE
 VICTIM WITH COOL WATER AND FAN THEM UNTIL EMERGENCY MEDICAL PERSONNEL ARRIVE.  

 B. HEAT EXHAUSTION. 
 
 1. HEAT EXHAUSTION IS ATTRIBUTED TO DEHYDRATION AND EXCESSIVE PHYSICAL ACTIVITY UNDER THE CERTAIN HEAT STRESS
 CONDITIONS. HEAT EXHAUSTION IS CHARACTERIZED BY AN INABILITY OF THE BODY TO GIVE OFF ENOUGH HEAT DUE TO HEAT OVERLOAD, BUT THE BODYS COOLING MECHANISMS ARE FUNCTIONING. SIGNS OF HEAT EXHAUSTION INCLUDE THE FOLLOWING: PROFUSE SWEATING, HEADACHE, TINGLING SENSATIONS IN THE EXTREMITIES, SHORTNESS OF BREATH, PALE, MOIST SKIN, WEAK BUT RAPID PULSE, NAUSEA, AND DIZZINESS. 

  2. PREVENTION. SAME METHODS FOR PREVENTING HEAT STROKE. 
 
 3. TREATMENT. SEEK IMMEDIATE MEDICAL ATTENTION.  REST CASUALTIES IN A COOL AND/OR SHADED ENVIRONMENT UNTIL SEEN BY AN EMERGENCY MEDICAL TEAM. INDIVIDUALS SHOULD FOLLOW THE REHYDRATION INSTRUCTIONS GIVEN IN (A-2) ABOVE. AFTER RECOVERY, EFFECTED INDIVIDUALS SHOULD NOT RETURN TO FULL PHYSICAL WORK ACTIVITY UNTIL
 EVALUATED BY MEDICAL. 

 
 C. HEAT CRAMPS ("MUSCLE CRAMPS"). 

 
 1. HEAT CRAMPS ARE MUSCULAR SPASMS CAUSED BY AN ELECTROLYTE IMBALANCE RESULTING FROM SIGNIFICANT WATER LOSS AND INADEQUATE WATER REPLACEMENT (E.G., NOT DRINKING ENOUGH WATER). INSUFFICIENT DIET OR IRREGULAR MEALS DURING THE DAY ALSO CONTRIBUTE TO INEFFICIENT ELECTROLYTE REPLACEMENT. SYMPTOMS OFTEN
 INCLUDE MOIST COOL SKIN AND PAINFUL CRAMPING OR STRAIN IN THE MUSCLES. 
 
 2. PREVENTION METHODS. EAT THREE WELL BALANCED MEALS A DAY AND DRINK WATER AS THE PRIMARY FLUID REPLACEMENT.  COMMERCIAL SPORTS- TYPE DRINKS CAN BE CONSUMED AS A SUPPLEMENTAL FLUID REPLACEMENT,
 BUT NEVER AS A REPLACEMENT FOR WATER. 

 
 3. TREATMENT. CEASE PHYSICAL WORK AND SIT IN A COOL AND/OR SHADED AREA. INDIVIDUALS SHOULD FOLLOW THE
 REHYDRATION INSTRUCTIONS GIVEN IN (A-2) ABOVE. SPORT-TYPE DRINKS ARE PERMITTED, BUT ONLY AFTER DRINKING THE MINIMUM WATER QUANTITY RECOMMENDED. IF MEALS WERE SKIPPED, TAKE A MEAL BREAK.  

 

 D. HEAT RASH ("PRICKLY HEAT"). 

 
 1. HEAT RASH IS CHARACTERIZED BY RED BUMPS, USUALLY IN AREAS WHERE CLOTHING IS RESTRICTIVE, AND GIVES RISE TO A
 PRICKLING PAIN OR IRRITATION. AS SWEAT INCREASES, THE IRRITATION INCREASES. HEAT RASH IS CAUSED BY THE BLOCKAGE AND INFLAMMATION OF SWEAT DUCTS. HEAT RASH INTERFERES WITH SLEEP, RESULTING IN DECREASED EFFICIENCY
 AND CUMULATIVE FATIGUE. IN ADDITION, HEAT RASH IMPAIRS SWEATING, DUE TO SWEAT DUCT BLOCKAGE AND INFLAMMATION, RESULTING IN A DECREASED EVAPORATIVE COOLING PROCESS. 
 
 2. PREVENTION METHODS. WEAR LESS RESTRICTIVE   CLOTHING AND KEEP THE SKIN DRY AND CLEAN, AS MUCH AS POSSIBLE. KEEP BERTHING AREAS COOL WITH FANS. TAKE FREQUENT SHOWERS FOR CLEANING. 
 
 3. TREATMENT. THE BEST TREATMENT FOR HEAT RASH IS TO PROVIDE A COOLER, LESS HUMID ENVIRONMENT AND KEEP THE AFFECTED AREA DRY.
