25
What system is replacing Halon
NOVEC & FM 200
26
What is a way to remove flammable liquid from a fire?
By closing a valve that’s supplying the flammable liquid
27
What type of fire extinguisher is good protection against reflash?
Dry chemical
28
What type of fire extinguisher does not offer good protection against reflash?
CO2
29
What is the most versatile, easiest, and readily available source of fire protection?
Water
30
American fire hoses are typically
2 1/2” & 1 1/2”
31
100psi ~
100ft stream
32
35 cubic feet of water =
1 ton
33
Sprinkler systems are commonly found on
Passenger ships & Ro/Ro
34
A 2 1/2” hose with 120 psi~ ~ | =~
800gpm 110 cubic ft 3 tons/minute
35
How did the S. S. Normandie capsize?
Excessive firefighting water pumped on board
36
An eductor utilizes
Venturi principle
37
Co2 can be
Hand held Semi portable Fixed systems
38
A fixed co2 system requires
Closed protected compartments, and releases calculated required quantity to extinguish the flames
39
What are some advantages to CO2 systems?
No consequential damage, it’s transported through long distances their pipelines, and it’s a relatively low-cost material
40
What are some disadvantages to CO2 systems?
High risk to personnel, large quantity of gas needed, cylinders have to be stored in an isolated space, many safety devices needed, and the action is not repeatable
41
What system is an alternative to CO2?
NOVEC
42
NOVEC advantages
Less environmental impact, less harmful to personnel, no special room, no residue, not stored under pressure, easier to handle, more effective on volume basis
43
NOVEC disadvantages
Hi refill cost, toxic gas my form due to fire in engine room
44
Class K fires are a
Subclass of class B fires.
45
Class K flames can be extinguished by
Wet chemical or dry chemical
46
Galley fire suppression systems typically have a
Remote actuating station
47
An exceptionally efficient fire safety technology, that uses significantly less water than traditional sprinkler systems while achieving a similar or better level of performance while minimizing fire and water damage is called a
Hi velocity fog
48
What occurs by self heating do to exothermic internal reactions followed by thermal runaway?
Spontaneous combustion
49
Name the three basic types of fire sensors.
Smoke detectors, heat detectors, flame detectors
50
Smoke detectors utilize
Optical and ionization
51
Heat detectors utilize
Rate of rise and fixed temperature
52
Flame detectors utilize
Ultraviolet, infrared, thermal imaging camera
53
What also makes a good fire detector?
Humans
54
What are the essential components of a fire detection system?
Sensors, central control, alarms, possible tie in with extinguishment
55
What is constructed to control the spread of fires on a ship?
Fire control bulkheads
56
Fire control bulkheads are spaced and arranged to create what?
Fire zones
57
Fire control bulkheads are classified as
A, B, C, depending on the ability to limit the spread of flame and smoke
58
Class a bulkheads are capable of preventing the passage of smoke and flame for how long?
One hour
59
Class B bulkheads are capable of preventing the passage of flame for
1/2 hour
60
How many firefighting protection outfits must be on a cargo ship and likewise how many on a tanker ship
Two on a cargo ship minimum of four on a tanker
61
What must a fire control station have?
The display of fire alarm system, cabinet containing the quick closing valve control, stop buttons for mechanical ventilation, smoke extraction cabinet, remote control cabinet for CO2 system, remote operation of fire screen doors, fireman outfit, SCBA
62
When must a muster list be posted?
Before the vessel begins voyage
63
Where must the muster list be posted?
Conspicuous places throughout the basil, the bridge, engine room, accommodation spaces
64
What is a main cause of spontaneous combustion?
Oily rags and poor ventilation
65
A vessel floats because
The gravitational force pulling it downward is offset by the upward buoyant force, hence a state of equilibrium
66
Archimedes principle states that the upward buoyant force that is exerted on a body immersed in a fluid =
The weight of the fluid that the body displaces
67
The buoyant force acts in the upward direction at the
Center of mass of the displaced fluid
68
The weight of the displaced volume of fluid will
Equal the weight of the floating body
69
As long as the value of G is offset by the value of B,
The vessel will remain a float
70
The locations in relative positions of B and G are crucial in maintaining
Upright flotation
71
The center of buoyancy is located
At the center of the immersed portion of the hull
72
The center of gravity is the point at which
The sum of the vertically acting downward force of gravity can be considered to act
73
The overall gravitational force acts through
The center of gravity
74
The ability of a vessel to float upright and return to an upright position when any upsetting force is no longer present is known as
Stability
75
When the center of gravity and the center of buoyancy are vertically aligned initially this is known as
Initial stability
76
When An upsetting force is introduced such as wind or waves
G remains in position, but B shift to the new center of the immersed hull
77
When G and B are vertically offset, what is then created?
The righting moment
78
The point where the B vector crosses the transverse center line is called the
Metacenter
79
B always acts vertically through the
Metacenter
80
The greater the distance between G and M, the greater the
Initial stability
81
The distance between the center of gravity and the metacenter is the
Metacentric height
82
A stiff ship, short rolling period, and cranky are all characteristics of a
Large GM value
83
Tender ship and long rolling period are characteristics of a
Small GM value
84
When a vessel is upright,
K, B, G, & M are all aligned on the centerline
