Describe the three phases of size-up and their relationship to problem identification. Three Phases of Size-up Phase one: Preincident information Phase Two: Initial Size-up OBJECTIVE Module 2 Overview
Describe the factors that affect size-up. Risk/Benefit Evaluation Command Decisions Brief Initial Report OBJECTIVE Module 2 Overview
Given a simulated structural fire incident, demonstrate the ability to conduct an effective size-up, identify the problems presented, and communicate critical information as part of a concise size-up report Phase Three: Ongoing Size-Up OBJECTIVE Module 2 Overview
Three Phases of Size-up • Phase One: Preincident information • Phase Two: Initial Size-up • Phase Three: Ongoing size-up
Phase One: Preincident Information • Size-up is more than what you see through the window when you arrive at the scene. • A wealth of information available prior to alarm.
Size-Up Definition Preincident information includes factors known before the incident that may affect decisions or actions.
WHAT TYPES OF INFORMATION ARE AVAILABLE AND USEFUL BEFORE THE INCIDENT
Value of Preincident Information to the Incident Commander (IC) • Understand what has happened. • Identify problems. • Predict what is going to happen. • Understand resource needs.
Value of Preincident Information to the Incident Commander (IC) • Development of strategy and tactics. • Identify safety considerations.
IT’S HARD TO OBTAIN PREINCIDENT INFORMATION WHEN THE FLAMES ARE LICKING AT THE BOXES OF DYNAMITE.
Preplans • Give the IC a jump start on understanding the situation and developing an action plan. • Can help IC consider all the important factors when used at the scene.
Occupancy Information • Occupancy type • Different problems • Impact on strategy and tactics
Occupancy Information • Building Construction • Construction type • Impacts on fire behavior • Vertical openings versus compartmentalization
Occupancy Information • Built-in protection • Sprinklers, standpipes, alarm systems, fire doors, etc. • Assist in controlling situation
Occupancy Information • Building contents • Impacts on action plan
Occupancy Information • Utility control • What utilities are present? • Where are controls located? • Positive effect on safety and incident control
Most commonly use extinguishing agent. Location Availability Reliability Delivery system Water Supply
Environmental Conditions • Can lengthen response times. • Can affect fire behavior. • Can affect how long and how fast firefighters can work. • Apparatus may freeze up or overheat.
Time of Day • Traffic at peak times can delay response. • Occupancy of buildings varies. • Volunteer and combination departments may respond with fewer firefighters during business hours.
Departmental Resources • Apparatus and equipment • Personnel
Interagency/Private Sector Assistance • Already there at many incidents. • IC must know what resources are available prior to the incident. • Many sources of assistance. • Maximizes use of fire department resources.
A rapid mental evaluation of various factors related to an emergency incident.
First Objective is to Identify Problem(s) • Calmly assess conditions. • First chance to get into proactive mode. • Done prior to defining solutions. • Potential hazards to firefighters
Use Preincident Information to Help With Initial Size-up • Preplans • Typical occupancy • Other resources responding
Use Preincident Information to Help With Initial Size-up • Water supply in area • Special hazards or problems • Environmental conditions • Time of day
Dispatch information can give an indication of the extent of problems • “Structure fire, 14 Railroad Street, Engines 1, 2, and 3, Truck 1 Respond” • “Receiving multiple calls, reported persons trapped, etc….”
What should initial size-up include? What do I Have
What should initial size-up include? What do I Have Where is it going?
Be Pessimistic Murphy’s Law is always on the incident.
What should initial size-up include? What do I Have Where is it going? How do I control it?
WALLACE WAS HOT can be used for training on the factors that impact size-up.

Trying to remember all 13 factors at the incident can make your head hurt • Not all factors are critical at every incident. • Key-in on those factors that apply.
