Answer 3

1. Closed-circuit systems • Also known as re-breather apparatus • Uses dried compressed air or an oxygen source stored in a cylinder. • Exhaled air in a re-breather apparatus stays within the system. Carbon dioxide is ‘scrubbed’ from the exhaled and the air is then recycled into the inhaled air. • Provides longer air-supply duration then open circuit. • This system is not used by the Edmonton Fire / Rescue Department; however it is used by the City in the water & sanitation services. 2. Open circuit systems • Uses dried compressed air stored in a cylinder. • In an open-circuit SCBA exhaled air is vented through a regulator to the outside atmosphere. • This system is used by the Edmonton Fire / Rescue Department. 3. Supplied air systems (SABA) • Uses dried compressed air stored in a cylinder. • Air is supplied to the SCBA via a hose connected to an air cart or other large air supply cylinder. • This system has limited use by the Edmonton Fire / Rescue Department on Ladder apparatus NFPA

• Dry system – not filled with water until needed in firefighting. Used only by firefighters. Must be manually charged by fire department. • Wet system – standpipe is filled with water and is pressurized at all times. • Wet/Dry Combination system – Portions of the system are pressured with water and other portions are pressured with air. The standpipe system can also be divided into one of three classes. * Class I - provides 65mm hose line connections to supply water. These are usually found in the stairwells of the high rise structure or at dedicated areas within a warehouse. * Class II – provides 38mm hose cabinets that may be used by either occupants or firefighters. * Class III – provides both a Class I and Class II standpipe system – hose cabinet and standpipe connection. The 65mm connection may be in the stairwell or found in the hose cabinet.

1. Natural Anchors 2. Structural Anchors 3. Pseudo Anchors

Answer 34

1. Anchor System 2. Body holding harness 3. Rope rescue plan 4. Brake, belay, haul system

Answer 35

I.D.E.A.S.  Integrity - What is the integrity of the anchor point? How is it rooted to the ground or building? Does it have sufficient mass to withstand the force that may be applied to it?  Direction of Force – What is the direction of the force of the load upon the anchor? The anchor should be in line with the force being applied to it or any anticipated direction of force. Incorrect alignment may cause torqueing forces to the anchor, unequal loading of the anchor points or a pendulum of the rescue load.  Equalization & no Extension - The anchor legs should have equal tension placed on both legs. This will enable the anchor points to share the load of the system. Also, there should be no extension to the system. Extension refers to the movement of the focal point, should one anchor leg fail there should not be any extension of the anchor legs causing high impact forces to be placed on the remaining anchor point.  Angles - Examine the anchor system for “critical angles.” Critical angles increase the force of the load on the anchor points. This may cause a failure of the anchor system.  System of anchors - What type of anchor system is required for the situation, and what are the advantages and disadvantages of designed system?

Answer 176

1. Fuel load 2. Structural load 3. Dead load 4. Live load Impact, Static, and Repeated Loads 1. Impact loads are sudden, one-time, short-term bursts of pressure that can produce very high stresses, especially when applied laterally. 2. Static loads are gradual or constant pressures applied over the long term. 3. Repeated loads are pressures applied intermittently over a period of time. 1. Compression loads squeeze and shorten a member. 2. Tensile loads pull apart or lengthen a member. 3. Shear loads cause the planes of the member to slide past one another. 4. Concentrated loads are focused in one small area, rather than spread across the length of the structural member. 1. Axial load is a direct, even pressure applied to the center of the structural member’s cross section at a right angle to that center of the plane. It can be either tensile or compressive. 2. Eccentric load tends to bend the structural member. It is a direct, even pressure applied to one side of the member, at a right angle to the cross section but not centered on it. 3. Torsional load is a twisting pressure applied, at an angle, to any place other than the center of the structural member. The twisting action creates a shear load in the member. Torsion often causes extensive collapse. 4. Suspended loads use rods and or cables to connect the suspended load to a main beam. The connectors can carry heat into the wood beam and ultimately cause a heavy suspended load to fall. Loads may also be suspended from bar joist trusses that can be greatly weakened by heat and flames.

Answer 177

Wall Materials 1. Concrete walls may require a pneumatic (jack) hammer; where as a metal wall may require only a reciprocating saw. In some cases, a masonry wall can be breached with a battering ram. 2. Brick and stone walls are, for the most part, veneer walls and are easily breached with properly selected tools. Most entries can be accomplished with normal firefighting tools and/or power saws. 3. Interior walls are usually made of a wood frame with a gypsum board (drywall) cladding. Standard fire fighting tools such as an axe will accomplish the breaching. 4. Walls made of fire-resistive materials are used to divide structures into compartments. They may therefore block or retard the spread of fire with in the structure. Breaching this type of wall may promote the spread of the fire with in the structure.

Answer 233

**Thermal layering** In a high rise heated smoke and gases will rise until their temperature and pressure equal ambient air. When this equalization occurs, the smoke will cease to rise. Smoke and products of combustion if remain cool will bank downwards from the state of equilibrium and contaminate lower levels. **Natural Stack Effect** Cooler outside air Hotter outside air **Reverse Stack Effect** Hotter inside air Cooler inside air **Mushrooming** Mushrooming is similar to stratification but the cause of lateral and downward migration is a physical barrier and not temperature / pressure equalization.

When responders operate in the non-intervention mode they must: 1. Pull out to a safe distance. 2. Inform dispatch of incident conditions. 3. Set up and maintain scene control. 4. Start the incident management system. 5. Evacuate, if necessary. 6. Call for additional resources.

Answer 253

* *1. Offensive Mode**: Aggressive containment, confinement, fire control, and/or rescue operations. Activities are planned to attack and mitigate the problem. * *2. Defensive Mode**: Less aggressive techniques of diking, damming, and diverting are used to reduce the impact of the incident. The incident commander gives up ground to the incident for greater safety of responders and the public. * *3. Non-intervention**: In industry, non-intervention is not usually thought of as an option. However, with hazardous materials response, taking no action other than limiting access may be the appropriate action to take. All incidents will end eventually. The wise commander will try to balance the risk to people and the environment against the effect of doing nothing.

1. Cloud The material rises above the ground or water in a ball-shaped, round pattern. 2. Plume The airborne hazardous materials adopt a haphazard pattern. Wind and topography shape the downrange course from the point of release. 3. Cone The hazardous materials take on a triangular shape. The apex starts at the breach with the wide base of the triangle downrange. 4. Stream The stream of hazardous materials is a liquid engulfment that follows the surface of the ground or water. Gravity and topographical features direct the stream 5. Pool The hazardous materials collect on the surface of the ground or water in a flat, round pattern. 6. Hemispheric The material assumes a semicircular shape that remains in contact with the ground or water. 7. Irregular The irregular pattern of engulfment has no definite shape or pattern. It basically includes those patterns of dispersal that do not fall into the other categories.
