Study Notes

Incident Management System (IMS) Commands and Structure

First company officer on the scene is in command until a chief officer arrives to assume command.
Conflicting orders from multiple supervisors lead to frustration due to violation of unity of command.
Division of labor in fire services is essential for assigning responsibility, preventing duplication, and making clear assignments.
Policies provide guidance for decision-making in various scenarios.

Procedures and Components of IMS

A procedure is a detailed guide directing specific actions.
Planning is a major function of the Incident Management System, crucial for effective incident control.
Essential components of an effective IMS include common terminology, unified command, and modular organization; prefire plans are not a core component.

NFPA Standards and Safety Protocols

NFPA 1500 outlines minimum health and safety program requirements for fire departments.
Emergency vehicle occupants should remain secured in their seats; riding on tailboards is prohibited.
The Incident Commander has the authority to order additional resources for large-scale incidents.

Role Designations within IMS

Divisions in IMS refer to geographical locations related to incident response.
Safety, Liaison, and Information roles are designated as command staff positions within IMS.
The Operations Chief implements tactical assignments while the Incident Commander sets strategic goals.

Incident Reporting and Fire Statistics

Arrival reports should include situation evaluations, selected attack modes, and command information.
Most structure fires, damage, injuries, and fatalities occur in residential areas, highlighting the need for focused safety measures.
The National Fire Incident Reporting System collects data about fire incidents across the U.S.

Communication and Reporting Procedures

Progress reports should be communicated every 10-15 minutes during an incident until controlled.
Emergency communication centers must be well-equipped and informed about on-scene actions.
Computer-aided dispatch improves response times and call volume handling.

Foam Usage in Firefighting

In-line eductors are the most common foam proportioners in firefighting.
High-expansion foam is effective for inaccessible basement fires.
AFFF operates on a Venturi principle, and proper mixing ratios are vital for effective foam application.

Properties and Application of Foam

Aqueous Film Forming Foam (AFFF) is used at concentrations of 1%, 3%, and 6%.
Class A foams lower the surface tension of water, enhancing fire suppression capabilities.
The effectiveness of foam varies based on the type of fuel involved, with polar solvents requiring special considerations for application.

Equipment and Techniques for Fire Suppression

Audible warnings signal evacuations and must be heard at significant distances (at least 500 feet).
Fire incident reports serve as legal documents and must accurately reflect the incident details.
The use of foam requires consideration of hydraulic compatibility between nozzles and eductors; both must have matching flow ratings for efficiency.

General Best Practices

Implementing an accountability system during evacuations is crucial for personnel safety.
Emergency communications should have backup power sources to ensure reliability.
Organizations must use standardized data collection systems to enhance response and reporting efficacy.### Firefighting Techniques and Concepts
Solubility: Ability to mix with water, crucial for understanding how substances behave in firefighting applications.
Friction Loss: Refers to the pressure lost as water moves through a hose line, impacting the effectiveness of water delivery at the nozzle.
Fire Control Strategy: Certain fires, particularly those involving pesticides and gases, may be better left to burn out instead of using water, as water could exacerbate the situation.
Flammable Liquid Fires: Best controlled using foam, which suppresses flames and prevents ignition spread.
Flash Points: Liquids with flash points below 100°F are classified as flammable, indicating high risks associated with ignition.
Flammable Vapors: Typically heavier than air, these vapors can pool in low areas, posing risks of ignition; proper ventilation is essential.
Positioning Fire Apparatus: Position vehicles uphill and upwind during flammable liquid spills to prevent exposure to fire or toxic vapors.
Combustible Liquids: These have flash points above 100°F, and understanding these characteristics helps in classifying fire risks.
Fire Incident Management: The primary concern is controlling ignition sources during flammable liquids incidents to prevent ignition and escalation.
Water Use in Fires: Water can serve as a cooling agent, mechanical tool, protective cover, or substitute medium during fire interventions.
Hose Crew Actions: After sealing a flammable liquid container, the crew should continue applying water as they exit the area to prevent reignition.

Foam and Firefighting Equipment

Foam Proportioning Methods: Include injection, premixing, induction, and batch-mixing; each method has specific applications in fire control.
Post-Class B Fire Actions: After extinguishing with foam, areas should be monitored for reignition, emphasizing the importance of vigilance after a fire.
Hydrocarbons: Identifying substances that are not hydrocarbons, such as ketones, aids in creating effective firefighting strategies.
Disconnecting Electrical Service: The safest method for firefighters is to shut off the main power breaker/fuse in the panel box to prevent electrical hazards.

Structural Considerations in Firefighting

Building Collapse Risks: The only effective measure to protect from imminent collapse is to remove personnel from the structure.
Roof Types: A pitched or gabled roof has an elevation at the center with sloped edges, which can influence fire behavior and access.
Structural Reinforcements: Signs such as large metal stars and tie rods indicate potential building collapse; firefighters should take special precautions in such cases.
Fire Resistive Construction Hazards: The primary hazard comes from the contents rather than the structural members, requiring specific strategies to mitigate risks.
Heat Transfer in Fires: Horizontal heat transfer can occur through wall openings and radiant heat but is not typically through ceilings and floors via direct flame contact.
Construction Resistance: Fire-resistant construction exhibits the greatest resistance to structural damage from fire, crucial for ensuring safety during firefighting operations.
