When a compartment is fully involved in fire, e.g. post-flashover, fire is most quickly spread to other compartments through openings such as doorways, vent ducts, and open pipeways and wireways. It will also spread to adjacent compartments by heat conduction through the bulkheads. Fires normally spread faster vertically to the space above than to adjacent horizontal spaces.

Question 12

Eyes watering and or burning, difficulty breathing, tingling or numbness of the tip of the tongue, tip of the nose, finger tips and/or toes is an indication of ……?

Answer 12

fuel combustion gases (stack gas) and fuel vapors.

Reference: OPNAVINST 5100.19F Navy Safety and Occupational Health (SOH) Program Manual for Forces Afloat, Sect B Ch 2 Para 4.b.7(7) Impact of Fuel Combustion Gases (Stack Gas) and Fuel Vapors on Exposure Limits.
(a) Fuel combustion gases (stack gas) and fuel vapors can have severe physiological impact on personnel. The effects of these environmental factors are intensified by heat stress. Heat stress causes the body to shunt blood to the skin and to cause skin blood vessel vasodilatation to remove heat. Also, exposure to fuel combustion gases and fuel vapors causes blood vessels in the skin to vasodilate. Blood vessel vasodilatation is greater from combustible gases or fuel vapors and heat stress in combination than vasodilatation from either separately. Personnel experiencing heat stress while exposed to combustible gases or fuel vapors results in increased vasodilatation, which in turn causes increased skin absorption of the combustible gases or fuel vapors. Also, the synergistic combination of vasodilatation from heat stress and from combustible gases or fuel vapors impairs the individual’s cardiac reserve (i.e., their physiologic capacity to respond to further stress by pumping more blood). Prolonged exposure to relatively low concentrations can impact the ability of personnel to work safely. If someone entering a workspace or area for the first time in approximately 4 hours or more can smell the odor of stack gas or fuel vapors, then a harmful concentration may be present. Personnel should be checked for the symptoms in the following subparagraphs 4b(7)(a)1 through 4b(7)(a)4.
1. Eyes watering or burning, or both.
2. Difficulty breathing
3. Tingling or numbness of the tip of the tongue, tip of the nose, finger tips and toes.
4. Generalized sensation of mild alcoholic intoxication without alcohol consumption within the past 24 hours.

Answer 16

Take salt tablets.

Reference: OPNAVINST 5100.19F Navy Safety and Occupational Health (SOH) Program Manual for Forces Afloat, Sect B Ch 2 Para 3. e. Recommendations for Working in Heat Stress Environments
(1) Drink more water than satisfies thirst, but not more than 1.5 liters (about one and half quarts) per hour. Do not wait until thirst transpires to start drinking (scuttlebutts must be readily available and in working order). It is important that personnel stay hydrated. Backpack-style devices (operated with a tube or straw) have proven very effective in helping personnel to stay hydrated. Water storage devices facilitating hydration, are available in the supply system (NSN 9Q-8465-01-396-9855) and may be helpful in preventing dehydration.
(2) Eat three well-balanced meals daily.
(3) Get adequate rest. At least 6 hours of continuous sleep per 24 hours is recommended.
(4) Do not take salt tablets unless under the direction and supervision of the MDR.
(5) Limit intake of caffeinated drinks.
(6) The fleet has used several cooling vests in the supply system in a limited capacity. Initial research on one of these vests shows that if properly used in a heat stress environment it can reduce thermal strain. However, when using cooling vests, personnel must adhere to PHEL stay times as described in this chapter until revised PHEL curves are established for the cooling vest.

Question 17
