NFPA 1620 Pre-Incident plans procedure
Step one

A
  1. Identify physical elements and site conditions:

This step is all about identifying all the structural elements of the building. The size and dimensions, construction, floor plan, stairwell locations, utilities etc

NFPA 1620 Pre-Incident plans procedure
Step two

A
  1. Identify Occupant Considerations:

This part of the preincident plan looks at the occupants their age and physical and mental condition and decided how and if they will be evacuated. the preincident plan should plan on where these occupants would be moved to and what services they may need. Long term tracking of the occupants may be needed as well.

NFPA 1620 Pre-Incident plans procedure
Step three

A
  1. Identify Fire Protection Systems and Water Supply

Evaluate the building size and contents to determine water supply. Document the location of hydrants and their flow rates, ideally the hydrants would feed off a large main as part of a grid system. If demand exceeds available water then preincident plan should identify a way to mitigate the lack of water ( relay operations or water shuttle). FDCs and FACPs should be noted.

Step four

A
  1. Identify Special Hazards:

Document any special hazards and ensure required resources (spec ops) are sent during emergencies. Special hazards may include flammable/combustable liquids, biological agents, chemicals etc. Pre-incident plan should note contact information for facility hazmat coordinator and location of material safety data sheet.

Q

246-247
NFPA 1620 Pre-Incident plans procedure
Step six

A
  1. Identify Special or Unusual Characteristics of Common Occupancy:

Particular hazards for each occupancy group researched then cross reference types of hazards with code and incidents with the goal of IDing hazards that specific occupancy groups tend to have with that particular building and try to plan for that hazard….ie multiple FFer deaths occur in places of assembly. Then analysis the specific assembly building and try to find ways to mitigate those hazards that contribute to those deaths.

What is the relationship between state fire codes and local fire code?

A

State fire codes are applied state wide and tend to set a minimum standard. Where local codes are only applicable within the jurisdiction and tend to be more stringent requirements.

Q

Authority having jurisdiction

A

term used in NFPA to refer to an organization, office or individual responsible for enforcing the requirements of a code or standard.

Authority having jurisdiction for a state would be the state fire Marshall.

AHJ has the ability to delegate the power to enforce the code to the fire officers, fire inspectors, and other individuals who actually conduct inspections.

Q

247-248

building code vs fire code

A

building code and fire code establish minimum safety standards.

Building codes contain regulations that apply to the construction of a new building or extension or major renovation of an existing building.

Fire Codes applies existing building and to situations that involve a potential fire risk or hazard.

Building code requires the sprinklers be installed fire code ensures the sprinklers are maintained and functioning properly.

Q

What are the two paths that a model code may be adopted by a jurisdiction?

A

Adoption by reference - where the jurisdiction passes an ordinance and adopts a specific edition of the model code. ie jurisdiction adopts NFPA1
Adoption by transcription when the adopts the entire text ie when jurisdiction copy the language of the code and insert that into the actual ordinance.

How long does code last?

A

For as long as the building is occupied for the same purpose. If the use of the building changes ie residential to assembly , or is extensively remodeled then the code must be brought current.

Q

249
What are the numbers behind sprinklers effectiveness?
NPFA’s U.S. Experience with Sprinklers

A

Sprinklers operated 91% of the time the fire was large enough to activate them
Of that 91% activation they were effective in controlling the fire 96% of the time. Giving a combined performance of operating effectively 87% of the time.

Wet pipe 89% effective …. Dry Pipe 76%

31
Q

249

What is the best method to ensure sprinkler systems work as they should?

A

Inspections

32
Q

249

What are the three primary components of water based fire protection systems?

A

Automatic sprinkler systems
Standpipe systems
Fire pumps

33
Q

250

Which systems requires less maintenance, dry pipe or wet pipe sprinkler systems?

A

wet pipe require less maintenance, since dry systems activations then require the whole system to empties and filled with air/nitrogen

34
Q

250

Deluge

A

wet or dry system where all sprinklers are open and ready to discharge water. Smoke, flame fire detectors activate and open control value and the whole system is activated dumping large amounts of water to quickly extinguish the fire.

35
Q

250

Preaction

A

similar to a dry system but includes a separate detection system that triggers the dry pipe to fill, sprinkler head then still has to activate.

36
Q

250

Standpipe systems

A 
class 1 - discharge 2.5 for FD use
class 2 -discharge 1.5 and hose for civilian use 
class 3 - both
37
Q

250

What are the four types of special extinguishing systems that may be used in various structures?

A
  1. carbon dioxide
  2. dry/wet chemical
  3. Halon/clean agent
  4. Foam
38
Q

251

Carbon Dioxide Systems

A

fixed system that discharge CO2 from either low -pressure or high-pressure tanks to protect specific devices or process or flood an enclosed space.

Extinguishes fire through displacement of oxygen. heavier than air.

39
Q

251

Dry/Wet Chemical

A

Fixed chemical extinguishing systems discharge a chemical extinguishing agent pipe, hoses, nozzle.

Wet chemical used in commercial cooking and may have a cap to ensure nozzle not clogged with grease. react with grease and form foam blanked.

Dry chemical leave residue that is difficult to clean up.

Both activated by fusible link or pull station

40
Q

251

Halon

A

Extinguishing agent of choice for computer rooms, great abut kills ozone layer so banned, legacy systems can still be charged.

New replacement clean agents work in the same way by flooding a room and displacing oxygen.

These chemicals are toxic and have an alarm that sounds warning people to get out before system activates.
10s-1min

41
Q

251

Foam systems

A

Low expansion foam systems used to protect hazards involving flammable or combustable liquids. Foam bubbles smother fire in foam blanket. high expansion foam excludes air and fill a large area with foam.

42
Q

252

The goal for an inspector doing a maintenance inspection

A

Observe the system and ensure that no fire hazards exist and confirm that the built in fire protection features are in proper working order.

43
Q

253

Construction Types

A

Type I, Fire resistive: construction elements are noncombustible protected from the effects of fire by encasing in concrete, gypsum, or sprain coatings. Most durable.

Type II, Noncombustible: Structural elements made of noncombustible or limited combustable materials. Structural elements are not protected from fire or limited.
Subtypes in rating hours.

Type III, Limited combustible (ordinary): load bearing walls are noncombustible masonry. Internal structural elements may be combustable or a combination of combustable and noncombustible. Usually no higher than four stories.

Type IV, Heavy timber: exterior walls are noncombustible and interior structural elements are unprotected wood beams and columns with large cross-sectional dimensions. Durable, may exceed water supply

Type V, Wood frame: the entire structure may be constructed of wood or any other approved material.
