IAAI/USFA Abandoned Building Project
Building Evaluation Presentation Outline

 

Introduction
This lesson is intended to prepare personnel to inspect vacant or abandoned properties and identify conditions that could lead to injury or death in the event of a fire in the property. The data collected as part of the inspection can then be used as part of a pre-plan for the structure and in the decision-making process of the community regarding the allocation of resources for the mitigation of the most hazardous properties. The evaluation form developed by the IAAI/USFA Abandoned Building Project is used as the basis for the program (Attachment A). Communities that choose modify the form to meet their specific needs should make adjustments to the program to reflect the modifications. A PowerPoint presentation designed to support this lesson is also available from the IAAI and USFA.

Objectives
At the completion of this program, participants will be able to

1. Describe the potential hazards that vacant properties pose to fire fighters
2. Perform an evaluation of a vacant property safely
3. Evaluate the potential for a fire in a vacant property to extend to an adjacent building
4. Evaluate the potential for a multi-room fire upon the arrival of the fire department
5. Evaluate the potential for abnormal fire development within a vacant property
6. Evaluate the potential for structural collapse early in the development of a fire in a vacant property
7. Evaluate the potential for fire fighters to become trapped or lost during fire fighting operations in a vacant property

Background
Vacant or abandoned structures are unsightly, attract criminal activity, and are a threat to public safety where ever they exist. The National Fire Protection Association (NFPA) estimates that there are more than 12,000 fires in these properties every year . 1 Of these fires, nearly 72% are of incendiary or suspicious origin and more that 5% are caused by children playing with matches. 2 Annually, these fires result in over 6000 firefighter injuries 3. NFPA statistics indicate that more fire fighters are injured while operating at fires involving vacant or abandoned properties that in any other property classification. The loss of six fire fighters operating in a vacant property in Worcester, Massachusetts, in December of 1999 was a tragic example of the hazards these buildings pose to communities.

The terms "vacant" and "abandoned" are often used interchangeably when talking about these buildings. There is, however, a subtle difference in the terms. Black's Law Dictionary defines vacant as "empty; unoccupied". The word abandon is defined as "to desert, surrender, forsake or cede. To relinquish or give up with intent of never again resuming one's right or interest." For buildings, the difference between vacant and abandoned is primarily related to the availability of an owner. Unoccupied buildings where there is a viable owner, i.e. one that is interested in the property and easily contacted, are considered vacant. Where there is no viable owner or an absentee landlord, the property is generally considered abandoned. Unoccupied properties that are secure and well maintained do not pose the same threat to public safety as those that are unoccupied and open to unauthorized access.

While no census data is available on vacant or abandoned buildings, researchers at Ohio's Miami University and the University of South Carolina conducted a survey of 100 cities and estimate that more than 18 percent of urban structures are unused. This estimate equates to thousands of building nationwide in communities both large and small. Another source, the Insurance Services Office, estimates there are 21,000 idle properties of 15,000 square feet or more in the United States.4 After the Worcester fire, many communities began exploring just how many buildings were vacant in their jurisdiction. The results are startling: Philadelphia reported more than 27,000 at-risk structures; in Worcester over 250 vacant structures were identified; smaller cities like Lewiston, Maine, identified nearly 60 vacant structures. An important finding of the Miami University survey was that approximately one third of the communities surveyed could not provide an accurate count of the vacant or abandoned properties in their jurisdiction.

Uninhabited buildings that are not secure - open to unauthorized entry - have a very high probability of intentionally set fires. When fires occur in these buildings, they present a host of unusual problems to fire fighters. Since the buildings are uninhabited, fires may develop for significant periods of time before they are detected and reported. The buildings may contain unprotected hazardous materials and fuel packages that would not be found in occupied buildings. The removal of equipment or structural components and deterioration due to age or weather can weaken the structure causing rapid failure early in a fire. Fire fighters may encounter open shafts, stairways, pits or holes in floors that would not be found in occupied structures. All of the factors that could contribute to dangerous conditions in vacant or abandoned structures and should be identified during the evaluation process. The evaluation form is designed to assist the evaluator in gathering information that can be used in the final evaluation of the hazard posed by a particular property.

Two of the thirteen recommendations of the NIOSH report on the 1999 cold storage building fire in Worcester, Massachusetts 5 related to the evaluation and marking of vacant and abandoned buildings.

Recommendation #1:
Fire departments should ensure that inspections of vacant buildings and pre-fire planning are conducted which cover all
potential hazards, structural building materials (type and age), and renovations that may be encountered during a fire, so
that the Incident Commander will have the necessary structural information to make informed decisions and implement an
appropriate plan of attack.


Recommendation #10 :
Fire departments should identify dangerous vacant buildings by affixing warning placards to entrance doorways or other
openings where fire fighters may enter.

The evaluation instrument provided with this program (Attachment A) is intended to assist communities in the inspection and evaluation of vacant and abandoned properties. The data developed during the evaluation can easily be incorporated into pre-plans for the buildings. Additional information regarding the Worcester Cold Storage fire can be found in the NIOSH report listed as a reference to this lesson.

Building Evaluation Activity

This activity is provided as an optional element of the IAAI/USFA Vacant/Abandoned Building Evaluation program. It is intended to provide participants with hands on experience in evaluating vacant or abandoned structures using the IAAI/USFA Evaluation form.

Materials and Equipment
· Personal protective clothing
· Flashlight
· Radio
· Evaluation forms
· Graph/grid paper
· Pen or pencil
· Ruler

Preparation and Safety
Locate a vacant or abandoned building that is available for the activity. Permission from the owner should be obtained prior to entry. The lead instructor should inspect each property prior to assigning teams to a building. Buildings with significant hazards should NOT be used for this activity. An instructor equipped with a portable radio should act as safety officer while participants are operating in the building.

Activity
· Divide the group into teams of 2 to 4 participants.
· Assign two or more teams to each of the properties identified for the activity.
· Teams should be instructed to conduct an evaluation of the structure independently. Each team should complete the evaluation form and develop a sketch of the assigned building.
· Teams assigned to each building should present their findings to the group individually. Any variations in evaluations of the building should be discussed in detail and a consensus achieved.
· Continue with reports until all assigned buildings have been discussed.

Using the PowerPoint Support Slides

The PowerPoint support slides provided with this lesson plan are intended to provide a graphical element to this presentation. While the talk can be delivered without the slides, seeing examples of what is being discussed will make a lasting impression on the audience.

The PowerPoint file can be projected using a computer and projector or the slides can be printed as transparencies. The presenter can use the features provided with PowerPoint to provide handouts to the participants by printing the Handout view from the file. Presenters should also review the Notes view of the file as additional information regarding most of the slides is provided.

For those with the capability, photos of buildings and issues from the local community can be easily added to the program to customize the program.
