ISO Flashcards
ISO
The operational safety triad
Creating a safe operational environment is dependent on three components
Procedures
Equipment
Personnel
___________ is arguably the least important facet of the safety triad
Equipment
There are three factors that must be addressed as part of the Personnel leg of the safety triad:
Training
Health
Attitude
Carbon monoxide
CO is considered a gas only- no flash point
Self ignition temp- 1,128*
Flammable range in air- 12-74%
Hydrogen cyanide
Flash point -0*
Self ignition temp-1000*
Flammable range in air-5-40%
Benzene
Flash point- 12*
Self ignition- 928*
Flammable range in air- 1-8%
Acrolein
Flashpoint- -15*
Self ignition temp- 450*
Flammable range in air- 3-31%
6 phased fire growth model
Ventilation controlled
- Ignition phase
- Initial growth phase
- Ventilation limited phase
- Explosive growth phase
- Fully developed phase
- Decay phase
Factors that influence the reading of smoke….
Weather
Thermal balance
Container size
Firefighting efforts
The three step process for reading smoke
- View the smoke VVDC
- Analyze
- Determine the rate of change of each attribute
You can acquire and maintain this risk perspective by frontloading an active knowledge of two things
- The fire service consensus risk value: NFPA and IAFC rules of engagement
- Values found at the local level:
Community expectations and Departmental values and skills
Dr Gassaway suggests there are 3 levels of SA
Capturing current cues and clues
Comprehending the situation
Predicting the future
ISO Read-Risk Model
3 step process
Step 1: Collect information- SA cues and clues
Step 2: Analyze
Step 3: Judge Risk
Keep a safe distance from down powerlines, at least?
10 feet
PV Solar Panel additional roof dead load
3 to 5 lbs per sqft
A standard 3x4 foot panel weighs approx 40lbs
Solar Thermal System roof dead load
5 to 8lbs per sqft.
Bright orange conduit or cable can indicate high voltage up to
Bright blue conduit or cable
700 volts is used in the drive train
Can indicate medium voltage drive trains
Vehicles power by compressed natural gas or propane are required to have a decal or sticker on……….
The right rear portion of the vehicle and adjacent to the refilling location
CNG labels are standardized as a ____________with the words CNG, LNG (a bleve hazard), or unodorized CNG within the black diamond
Blue Diamond
Propane powered vehicles should have a ……….
Black diamond with the words “propane” or “LPG” within
Preventative Actions for Hazardous Energy
General actions that and ISO should consider to help prevent injuries and deaths
Awareness-Communication
Avoidance-Zoning
LOTO
Protective Cooling
Ergonomic Stressors
Physical setting
Worker relationship to the setting
Task requirements
Ergonomic Abatement Strategies
Awareness
Accommodation
Acclimation
Core temps above _____ or below_____ will start to affect physical performance
Above 101*
Below 96*
The prevention of thermal stress Injuries can be accomplished through……
Accommodation
rotation
hydration
___________is the leading cause of FF injury and death
Overexertion
The two most common approaches to ISO duties include the use of _______ and the use of________.
Checklist
action models
To be effective, checklist and action models must have certain qualities that make them usable:
Flexibility, adaptability, cyclicity, proactivity, and reactiveness
ISO focus areas that are common to all incidents:
Risk-taking levels, personnel safety systems, and control zones.
Personnel safety systems that require ISO focus at all incidents:
Personnel accountability systems
Rehabilitation
Principal hazards at structure fires typically fall into general categories adding significant risk taking threats.
Hostile fire events
building geometry
collapse potential
hazardous energy
NFPA 1710 summarizes that _____ persons are needed for a simple low hazard single family dwelling fire
14 persons
Resource effectiveness is tied to….3 things
Resource allocation
Task applications
Operational effectiveness of crews
Recon efforts at structure fires.
As a starting place, the I SO uses reading smoke, building, and hazardous energy skill sets to define the incident environment in three dimensions:
The principal hazard,
environmental integrity,
and the effects of surrounding elements
