Study Notes
Size-Up in Firefighting
- Size-up is the evaluation process of conditions impacting fire outcomes, performed by all firefighters.
- Newer firefighters’ perceptions improve with experience, leading to more accurate size-ups.
- The officer in command has broader responsibilities requiring extensive consideration during size-up.
- The size-up process starts when the alarm is received and continues until the emergency is under control.
Key Information Indicators
- Time of day significantly affects the situation; for example, a fire at 2:30 am likely means most people are asleep, indicating potential complications.
- Location knowledge allows experienced firefighters to identify potential hazards and assess the situation accurately.
Importance of Street Numbers
- Odd-numbered addresses typically indicate the east side of north-south streets and the north side of east-west streets.
- Familiarity with street numbering helps firefighters locate and respond effectively to fires.
Life Hazards
- Life hazards can exist even in commercial fires, particularly in mixed-use buildings where occupants may be trapped.
- Building collapse is a major risk if structures suffer extensive fire damage for more than 20 minutes.
- Firefighters encounter life hazards from both civilians and their own risks, necessitating careful evaluation.
Crew Response
- Volunteer departments face staffing challenges during holidays and events, affecting response capabilities.
- Crew members should begin size-up mentally while preparing to respond.
COAL WAS WEALTH Acronym
- This acronym helps firefighters remember vital elements to consider during size-up:
- Construction
- Occupancy
- Apparatus and Personnel
- Life Hazard
- Water Supply
- Auxiliary Appliances
- Street Conditions
- Weather
- Exposures
- Area
- Location and Extent of Fire
- Time
- Height
Strategies to Mitigate Life Hazards
- Reducing life hazards can involve procedures like improving building codes, installing sprinklers, and ensuring proper exit facilities.
- Firefighters must identify hazardous conditions and act to mitigate them as necessary.
Occupancy Considerations
- The type of occupancy influences the response strategy and life hazard assessment.
- High-risk occupancies include schools, hospitals, and residential buildings, whereas storage facilities typically pose lower risks.
- Not all structures provide equal risk, and understanding these can guide aggressive tactics efficiently.
Firefighter Safety and Risk
- Caution is paramount in nonresidential structures where the likelihood of life hazards changes with conditions.
- Statistics show a higher death rate for firefighters in commercial structures compared to residential ones, emphasizing the importance of situational awareness.
Time Impact on Operations
- Time of day influences not just occupant risk but also potential delays in response due to traffic or busy hours.
- Certain times of the year affect staffing availability, particularly in volunteer departments, which requires planning for worst-case scenarios.
Critical Information and Technology
- Utilizing systems like Computer-Aided Dispatching (CADS) can improve situational awareness by providing vital preplanned hazard information quickly.
- Regular updates and inspections of preplanned information in CADS are essential for maintaining firefighter safety.
