Public Fire Safety

Question 0

what are some internal problem areas and give examples

Answer 0

environment combustibility - proliferation of combustible materials in construction

proliferation of ignition sources - pilot lights, high temperature electrical resistors in electrical equipment, standard electrical installation

building deficiencies - lack of adequate exits, space separation, fire resistive interior finishes, fire separation (doors)

private fire protection deficiences - poorly designed and maintained fire protection systems, compromises in fire ratings and separations and minimal installation of fixed protective systems

Question 1

List some responsibilities of health and safety professionals

Answer 1

eliminating fire causes
providing safeguards to mitigate hazards that cant be eliminates
containing small fires
preventing fire deaths and serious injuries
minimizing fire consequences for business and social life of affected community

Question 2

what are some external problem areas

Answer 2

public apathy - lack of appreciation of resource equipments and regulatory emphasis, reduced funding due to decreased fire incidents over time

research deficiences - limited fire safety on new building products and finishes in terms of smoke emission, toxic gas release and flame spread

Question 3

What is NIMS

Question 6

What is an IAP

Answer 6

Incident Action Plan

Question 7

What does an IAP provide

Answer 7

a coherent means to communicate the overall incident objectives in the context of both operational and support activities

Question 8

What operational periods are IAPs developed for

Answer 8

12 hours long

Question 9

Who does IAP depend on to accomplish response tactics

Answer 9

management

Question 10

What are the objectives of an IAP used for

Answer 10

developing and issuing assignments, plans, procedures and protocols

directing efforts to attain the objectives in support of defined strategic objectives

Question 11

What is done with the results of an IAP

Answer 11

they are documented and fed back into planning for the next operational period

Question 12

What does the ICS require in terms of accountability

Answer 12

orderly chain of command

check in for all responders, regardless of agency affiliation

each individual involved in incident operation to be assigned 1 supervisor

Question 13

What is a supervisor called

Answer 13

unity of command

Question 14

What does BLEVE stand for

Answer 14

Boiling Liquid Expanding Vapor Explosions

Question 15

what is BLEVE

Answer 15

a type of explosion that can occur when a vessel containing a pressurized liquid is ruptured. it can be extremely hazardous

Question 16

What is BLEVE a result of

Answer 16

a ruptured vessel containing a liquid substantially above its atmospheric boiling point. the vapor portion may leak rapidly, lowerig the pressure inside the container causing violent boiling of the liquid which rapidly liberates large amounts of vapor which can be extremely high causing a wave of overpressure (explosion)

Question 17

In BLEVE situations, how is the substance stored in the vessel

Answer 17

partly in liquid form with a gaseous vapor above the liquid filling the remainder of the container

Question 18

what causes vessel rupture

Answer 18

corrosion or failure under pressure

Question 19

What can also cause BLEVE

Answer 19

external fire near storage vessel causing heating of contents and pressure build up

Question 20

Constant heating of tanks designed to withstand great pressure can cause the metal to soften and fail. True or false

Answer 20

true

Question 21

what factor causes the tank to rupture faster

Answer 21

if the tank has no liquid and is being heated because the liquid wont absorb heat from metal

Question 22

are relief valves a guarantee that the tank wont fail

Answer 22

no because the valves relief extra pressure but tank will fail if its not relieved fast enough

Question 23

what susbtances are associated with BLEVE

Answer 23

flammable and non flammable shbstances even ones known for being extremely cold, refigerants

Question 24

is BLEVE a chemical explosion

Answer 24

No

Question 25

what is a possible aftermath of BLEVE if the substance is flammable

Answer 25

the resulting cloud of the substance will ignite forming a fireball and possibly fuel air explosion - vapor cloud explosion

Question 26

what happens if the materials are toxic

Answer 26

large area will be contaminated

Question 27

what is a major concern of fire fighters when attempting to control a blaze

Answer 27

structural collapse

Question 28

why are wildland fires significant

Answer 28

wildland is of great importance to the overall economy and fires will lead to loss of timber, wildlife and ecosystem impairment
