to establish safe work schedules in heat stress environments. Aboard ship, heat stress conditions can occur in almost any space. The causes of heat stress conditions are steam and water leaks, ventilation system deficiencies, missing or deteriorated insulation, and weather conditions of high heat and humidity. Prolonged exposure to heat stress conditions can cause heat exhaustion or heatstroke. These injuries occur when the body temperature continues to increase. The first signs are— Increased body temperature causing fatigue Severe headache Nausea Reduced physical and mental performance If not immediately and properly treated, these injuries can be life threatening. The best way to control heat stress hazards is to follow recommended work practices and procedures. Every ship in the Navy has a heat stress monitoring program. This program is designed to assist personnel that may be required to work in a heat stress environment by limiting the time they spend in a high heat stress situation. Personnel required to work in a heat stress environment receive training at regular intervals. Heat stress not only affects personnel that work below decks or in confined spaces but also personnel that work topside. Read your command’s heat stress instruction; it may help you work smarter and safer. COLD WEATHER The Navy conducts operations in areas where weather is often a problem. You have already learned about the possible problems that you may meet in the Tropics. Now, you will learn about the problems you may face when the Navy operates in severe cold weather areas. These problem areas range from the Antarctic to the northern regions of the Pacific or Atlantic Oceans. Your major health risk when working in these areas is hypothermia. Hypothermia results when the temperature of the body reaches subnormal levels. First aid for hypothermia, like that for heat stress, must be immediate. Other safety factors involved with operations in colder regions include ice accumulation on ships’ decks and superstructures or when outside bulkheads or fittings become so cold that, when touched with bare skin, the skin sticks to these objects. To protect yourself from hypothermia if you’re working topside or go topside as part of your duties, you need to wear clothing designed to maintain body heat. You need to limit the amount of time you’re exposed to such conditions. If you work topside and start to lose feeling on any part of your body, get inside and warm up. Safety is paramount! REVIEW 12 QUESTIONS Q1. Heat exhaustion and heat stroke are life threatening. List the symptoms of heat exhaustion and heat stroke. a. b. c. d. Q2. What is the major health threat of cold weather? GENERAL PRECAUTIONS The precautions that follow are general, all-around safety practices that don’t fit into any particular category. Some apply to several situations. Failure to observe any one of these practices could result in a serious mishap. Use tools that fit the work being done. Screwdrivers aren’t meant to be used as punches. 19-23 Student Notes:
