NICET Fire Alarm Systems Level IV
37004 HAZARD ANALYSIS
---------------------

37004 is a Level IV General Core work element.

General Work Elements are categorized as either Core or Non-Core
Work Elements. All Level III General Core Work Elements
constitute a mandatory requirement for achieving certification
at Levels III and IV.

37004 DESCRIPTION
Analyze the fire threat in a given facility and select the
optimum alarm equipment to deploy against that threat.
(NFPA 72, SFPE Handbook of Fire Protection Engineering)

37004 REFERENCES:

37004 DESCRIPTION BREAKDOWN:
"Analyze the fire threat in a given facility and select the
optimum alarm equipment to deploy against that threat."

Glossary of terms

Hazard. The relative fire hazard differentiating two materials
is the relative harm they offer when they both burn under the
same circumstances. This definition means that it is impossible
to discuss fire hazard or fire risk without knowing the
circumstances surrounding the two materials. These circumstances
considered together comprise the fire scenario for which the
hazard is to be assessed.

Risk. Fire risk is the expected loss from a fire of given
severity. For example, the probability of a fire in a given
environment may be very high, but the addition of a sprinkler
system may considerably reduce the risk of a serious fire.
Describing a fire risk carries requires a description of the
likelihood and the severity of the event.

NFPA 72-1999 B-2.3.1.2.2 Fire characteristics include:
1. Ignition sources
   a. Temperature
   b. Energy
   c. Time
   d. Area of contact with potential fuel(s)
2. Initial fuels
   a. State (solid, liquid, gas spray, vapor)
   b. Type and quantity of fuel
   c. Fuel configuration
   d. Fuel location (against wall, in corner, in open)
   e. Rate of heat release and fire growth
   f. Type and production of fire signatures (smoke, CO, CO2, etc.)
3. Secondary fuels
   a. Proximity to initial fuels
   b. Amount
   c. Distribution
   d. Ease of ignitability (see initial fuels)
   e. Extension potential (beyond compartment, structure, area,
	 if outside)

NFPA 72-1999 B-2.3.2.1 Fire development varies depending on the
combustion characteristics of the fuel(s) involved, the physical
configuration of the fuel(s), the availability of combustion air,
and the influences due to the compartment.

Fire growth and development are limited by factors such as
quantity of fuel, arrangement of fuel, quantity of oxygen, and
the effect of manual and automatic suppression systems.

NFPA 72-1999 Appendix B A fire detection system can be designed
to detect a fire at a certain size in terms of its heat release.

Fire Protection Handbook 4-194 A quantitative measure of the heat
release rate (HRR) of burning furniture can be determined by
using a large-scale calorimeter developed by NIST, The National
Institute of Standards and Technology.

Heat release rates for individual pieces of furniture is
available in NFPA 72-1999 Table B-2.3.2.3.2(e)

NFPA 72-1999 B-2.3.3 Once the design objectives, the potential
fire scenarios, and the room characteristics are well understood,
the designer can select an appropriate detection strategy to
detect the fire before its critical fire size (Qcr) is reached.
Important factors to consider include the type of detector, its
sensitivity to expected fire signatures, its alarm threshold
level and required duration at that threshold, expected installed
location, and freedom from nuisance response to expected ambient
conditions.

Fire detection systems provide early warning to provide the time
necessary for occupants to escape a fire. Determining the Time
Available to Escape (TAE) involves a comparison of the relative
hazard posed by products in the same application.

The Escape Margin = Time Available to Escape (TAE) minus Time
Needed to Escape (TNE)

The type of fire and rate of fire growth determines the extent
of the hazard and the type of automatic fire detector best suited
for the hazard. For example:
 o Fast flaming fire
 o Slow smoldering fire
