Once  the  cylinder  valve  has  been  turned  on,  it provides a continuous air supply to the system regulator via the high-pressure hose. The pressure is reduced by the regulator for use by the wearer, and the low-pressure hose carries the breathable air into the facepiece. As a safety  feature,  these  are  positive  pressure  style regulators, which means that the air supply to the mask is just above any demand requirements eliminating any possibility of toxic fumes from entering the wearer’s mask. The time each cylinder lasts will be determined by a number of factors. The main factors will be the physical condition and size of the wearer and the work to be done. Generally, each bottle will last approximately 30 minutes from the time it is activated. REVIEW 5 QUESTIONS Q1.  How many minutes of air is the EEBD designed to provide? Q2.  Why should you stay away from open flames when you first remove an EEBD? Q3.  What should you listen for when donning an EEBD? Q4.  What  device  is  worn  by  engineering  watch standers? Q5.  What is the effective time of an OBA? Q6.  When do you pull the cotter pin on an OBA canister? FIREFIGHTING Learning Objectives: When you finish this chapter, you will be able to— Recognize the properties of a fire triangle and fire tetrahedron. I d e n t i f y   t h e   c o n d i t i o n s   n e c e s s a r y   f o r spontaneous combustion. Identify the types of heat transfer. Fire is a constant threat aboard ship. All possible measures must be taken to prevent a fire, or if one is started, to extinguish it quickly. Fires may start from s eve r a l c a u s e s — s p o n t a n e o u s c o m bu s t i o n , carelessness, hits by enemy shells, or collision. If the fire is not controlled quickly, it may cause more damage than the initial casualty and could cause the loss of the ship. FIRE AND FIREFIGHTING You cannot win against a fire. You can fight the fire and you can hold down its damage; but some property will be destroyed and, all too often, people will be injured or killed. Time is always lost, productive work is stopped, and additional effort and materials are required to make repairs and to clean up the mess. The objective of fire prevention, therefore, is to prevent  fires  from  starting.  Fire  prevention  is  an all-hands, all-day, all-night, heads-up effort. A cigarette tossed in the wrong direction can cause as much damage as an enemy bomb. An oily wiping rag or a sparking tool can be as dangerous as an open flame in a gasoline depot. Each ship is required to institute and maintain a fire prevention program. Your part in the fire prevention program is as follows: Ensure that all gear is stowed properly. 12-18 Student Notes:
