2  Heat stress is any combination of air temperature, thermal radiation, humidity, airflow, workload, and health conditions that may stress the body as it attempts to regulate body temperature.  Ships shall not expose personnel to excessive heat stress and shall provide a shipboard work environment that minimizes the probability of such exposure. CONFIDENTIAL 2

3  To obtain accurate and reliable data on heat stress conditions, ships shall conduct heat stress surveys to record dry-bulb (DB), wet-bulb (WB), and globe temperature (GT) readings.  We must take DB and WB temperature with both thermometers shielded from radiant heat and the WB also must be properly ventilated to determine the effects of airflow. CONFIDENTIAL 3

4  The Navy uses either a wet-bulb (WBGT) meter or an automated heat stress system (AHSS) to measure each of the above temperatures.  WBGT index- is calculated using dry bulb, wet- bulb, and globe temperature. CONFIDENTIAL 4

5  Machinery spaces  Laundries  Sculleries  Galleys  Incinerator rooms  Flight decks  Steam catapult rooms CONFIDENTIAL 5

6  Other factors that reduce physical stamina and enhance susceptibility to heat stress are:  Dehydration  Lack of sleep  Illness  Use of medication  Drugs  Alcohol  The presence of atmospheric contaminants such as combustion gases or fuel vapors. CONFIDENTIAL 6

7  Heat acclimatization occurs gradually, usually requiring three weeks or more (although most of the process occurs in the first week). CONFIDENTIAL 7

8  Commanding Officer  Establish and enforced an effective heat stress policy  Review and initial all surveys  Investigate all heat stress injuries  Report heat related issues  MDR  Review all engineering and non-engineering to determine obvious inaccuracies  Report to CO  Provide training to divisions  Prepare reports according to paragraph BO204f  For submarines, the MDR conducts heat stress surveys in engineering spaces. CONFIDENTIAL 8

Limit personnel heat exposures accordingly, except as approved by the commanding officer in an operational emergency.  If maintenance or repair is required, record all heat stress related deficiencies on current ship’s maintenance project (CSMP). Appendix B2-B provides heat stress troubleshooting and recommended repair actions CONFIDENTIAL 9

10 (1) Ensure dry-bulb thermometers are installed per paragraph B0204b(1) and temperatures are monitored and recorded per paragraph B0204b(3) and (4). (2) May assign and qualify departmental personnel to conduct heat stress surveys or access AHSS readings of  departmental spaces. Qualification of personnel shall be as specified in paragraph B0206b. (3) Ensure the heat stress surveyor conducts heat stress surveys per B0204c(4) and B0204c(5). (4) Assign and qualify supervisors to review dry-bulb temperatures or access AHSS readings and take the required actions per paragraph B0204. (5) Review heat stress surveys and ensure stay times for personnel are being properly determined as specified in paragraph B0205. Limit personnel heat exposures accordingly, except as approved by the commanding officer in an operational emergency. (6) If maintenance or repair is required, record all heat stress related deficiencies on current ship’s maintenance project (CSMP).

11  (1) Limit personnel heat exposures per established stay times, except as approved by the commanding officer in an operational emergency.  (2) If maintenance or repair is required, record all heat stress related deficiencies on Current Ship’s Maintenance Project (CSMP). Appendix B2-B provides heat stress troubleshooting and recommended repair actions. CONFIDENTIAL 11

12  A trained person assigned to conduct or review AHSS readings for any required surveys.  Be personal qualification standard (PQS) qualified per NAVEDTRA B, heat stress monitor.  Perform heat stress surveys as required by paragraph B0204. CONFIDENTIAL 12

13  Thermometer (alcohol in glass - NSN 9G ) shall be permanently mounted at watch and workstations throughout the ship where heat stress conditions may exist.  Mounted in non-air conditioned spaces, not normally manned, in which personnel may have to periodically work or conduct maintenance, such as storerooms.  May be hung in or out ventilation air stream, must be hung at least 2 feet opening.  Plastic tie wrap or string (never hang with metal wire)  DOES NOT REQUIRE CALIBRATION CONFIDENTIAL 13

14  shall be mounted in a position so they indicate the most accurate representative temperature for the area where workers/watch standers spend the majority of their time  NOTE:  Dry bulb Temp Readings should also be mounted in these area in order manual readings are necessary! CONFIDENTIAL 14

15  The ship shall record DB temperature readings when the ship is underway or when potential heat stress conditions exist while in port  Assigned personnel shall monitor compartments as follows:  (a) Every four hours for manned spaces if DB temperatures do not exceed 85 degrees Fahrenheit.  (b) Every hour for manned spaces if DB temperatures exceed 85 degrees Fahrenheit.  (c) Every hour at temporary installations where the DB temperature exceeds 85 degrees Fahrenheit during repair or maintenance operations. CONFIDENTIAL 15

16  Drink more water than satisfies thirst, but not more than 1.5 liters (about one and half quarts) per hour  Eat well balance meals  Get at least 6 hours of sleep  Except where fire retardant or fire-fighting clothing is required, wear clean clothing composed of at least 35 percent cotton (more natural fiber content allows more effective evaporation of water from clothing).  Do not take salt tablets  Limit caffeine intake CONFIDENTIAL 16

18 The CO will ensure a HCP is maintained in their command.  The goal of the hearing conservation program (HCP) is to prevent occupational hearing loss and assure auditory fitness for duty of all Navy personnel. The CO will ensure a HCP is maintained in their command.  The goal of the hearing conservation program (HCP) is to prevent occupational hearing loss and assure auditory fitness for duty of all Navy personnel. 18

19  He/She shall do three things: 1. Request assistance from an industrial hygienist or occupational audiologist to conduct noise measurement and exposure analysis (survey) of areas and equipment. 2. Maintain a record of noise hazardous areas and equipment. 3. Periodically reviews records for any trends that could indicate inadequate use of hearing protection. 19

20 He/She shall:  (1) Maintain and ensure proper calibration of sound level measuring equipment.  (2) Annually, certify audiometric testing booths installed aboard the ships. 20

21  He/She shall 1. Ensure personnel with hazardous hearing exposure use proper hearing protection. 2. Ensure that a space or piece of equipment that is designated as noise hazardous is properly posted and labeled. 3. Ensure all personnel required to wear personal hearing protection are trained 4. Ensure personnel report for scheduled audiometric testing and training. 5. Ensure that personnel who require hearing retests due to a significant threshold shift (STS) are excluded from hazardous noise areas 6. Coordinates with medical department representative to identify personnel routinely exposed to hazardous levels of occupational noise

22 1. Coordinates with DIVO to identify and maintain rosters. 2. Train personnel during INDOC 3. Ensure annual training is completed 4. Schedule personnel in HCP for annual audiometric testing. Ensure that all test results have been entered into each individual’s health record. 5. Ensure all personnel that need retest are excluded from hazardous areas. 22

23  NAVMED 6260/2A or equivalent shall be used to label smaller, individual pieces of equipment or tools that produce hazardous noise.  Noise hazard warning signs and labels shall be annotated as to their circumstances or operations that create the noise hazardous condition when hearing protection is required  (e.g., when generator is operating).  The outside of doors are labeled for potential hazard 23

24  Hearting test  REFRENCE Baseline test-everyone in HCP gets, form used DD-2215, no exposure to workplace noise for 14 hours.  Booth used for testing is certified annually.  Monitoring Hearing test- annual for ppl in HCP.  Removal Hearing Tests. Individuals who are removed from hearing conservation will be given a hearing test to document auditory status at the time of removal from noise hazardous duties. Results of this test will be recorded on DD

25  Disposition Following Monitoring Hearing Tests. Pure tone air conduction monitoring hearing tests are designed to detect small changes in hearing and identify problems before the individual suffers hearing loss that interferes with verbal communications.  Re-established Reference Audiograms. Monitoring audiograms are compared to the baseline or reference audiogram to determine changes in hearing levels.  Termination Hearing Tests. Personnel shall receive a hearing test upon termination of service. 25
