Community Risk Reduction

The safest emergency is the one that never happens.

Most of what a fire department responds to is predictable in aggregate, even when no single incident is. Community risk reduction is the work of finding the households, buildings and populations where the next one is most likely, acting before it happens, and measuring whether the action changed anything. The technology is mostly about joining data a department already holds to data it does not, and about keeping track of work that happens nowhere near an incident.

Emergency response deals with what has already happened. Community risk reduction asks a different question: can we find out where harm is most likely to occur, and do something about it before the call comes?

It is not another name for public education, and it is not the fire prevention bureau under a newer heading. It is an all-hazards, data-informed process — identify the risks that actually exist in this community, decide which of them to work on, act in the ways most likely to change the outcome, and measure whether anything changed. Fire is part of it. So are falls, overdoses, crashes, heat, drowning and everything else a department is called to.

The part that makes it work is the last step. Prevention has always been done. What is newer is the expectation that a department can say who was helped, by how much, and how it knows.

From response to risk reduction

The whole of CRR is five steps in a loop. Everything else on this page is detail about one of them.

  1. Step 1 of 5Identify

    What risks actually exist in this community? Not the ones that make the news, and not the ones a neighboring department has — the ones the local record shows.

  2. Step 2 of 5Prioritize

    Which of them carry the greatest probability, consequence or vulnerability, and which offer a realistic chance of doing something about it? Not everything important is changeable.

  3. Step 3 of 5Intervene

    What action is most likely to change the outcome? Usually more than one kind, aimed at a specific population in a specific place.

  4. Step 4 of 5Measure

    Did the intervention reduce risk, or only produce activity? This is the step that gets skipped, and skipping it is what makes prevention hard to fund.

  5. Step 5 of 5Adapt

    Continue, change or stop, based on what the measurement showed. A program that cannot show an effect has to be allowed to end.

It is a loop, not a project. The measurement of one cycle is the identification step of the next.

What is a community risk assessment?

A community risk assessment, or CRA, is the documented answer to the question "what is actually happening to people here, and to how?" It is the foundation the rest of CRR stands on, and it is a piece of written work rather than a piece of software.

The recognized references for how to do one are NFPA 1300, Standard on Community Risk Assessment and Community Risk Reduction Plan Development, and the material published by the U.S. Fire Administration and the National Fire Academy. Both are in the research library below, with their addresses.

The most common mistake is to treat the assessment as a mapping exercise. A heat map is a picture of where incidents happened. It is not an assessment, because it does not say who was harmed, why it kept happening, or what could realistically change it.

What a credible assessment looks at

No department has all of this, and an assessment that waits for all of it never gets written. Start with what you hold and add to it.

  • Demographics — age, household composition, language, tenure
  • Geography — terrain, access, distance, water supply, wildland interface
  • Building stock — age, occupancy type, construction, sprinkler and alarm coverage
  • Incident history — what you have been called to, where, and how often
  • EMS demand, including repeat callers and the conditions behind them
  • Fire loss — injuries, deaths, dollar loss, and the causes behind them
  • Inspection history and code violations
  • Social vulnerability — poverty, isolation, disability, transport access
  • Economic characteristics of neighborhoods, not only of the jurisdiction
  • Critical infrastructure and the places where a failure harms many people
  • Wildland-urban interface exposure
  • Community service organizations already working with the same households
  • Your own response capability — staffing, apparatus, travel time, mutual aid
  • Emerging hazards, including ones your incident history has not recorded yet

Most of this exists. Very little of it is in one place, which is why the assessment is work rather than a query.

The questions an assessment has to answer

If the finished document answers these, it is an assessment. If it answers only the first two, it is a map.

Who is being harmed?

Named as a population, not as a jurisdiction. "Adults over 65 living alone" is an answer. "Our residents" is not.

Where is it happening?

At the smallest level the data honestly supports — a tract, a corridor, a set of parcels. Citywide averages hide the neighborhoods that need the work.

What is happening?

The specific event. "Cooking fires between 5pm and 8pm" points somewhere. "Fires" does not.

Why is it happening?

The conditions behind the event. This is the question that turns a statistic into something you can act on, and the one no dataset answers on its own.

How often?

Frequency over a period long enough to be more than noise, compared against a baseline you can defend.

How severe are the consequences?

Injuries, deaths, displacement, loss. A rare event with severe consequences may outrank a frequent one.

What could realistically change it?

Given your staffing, your budget and your partners. An intervention nobody can deliver is not a finding.

The five E's of community risk reduction

Five kinds of intervention. The point of naming them is that the first one is not the only one, and on its own it is rarely the strongest.

Education

Teaching people what the risk is and what to do about it.

Fire service: teaching residents to test an alarm and replace the battery, or what to do if a pan catches fire.

All hazards: teaching households how to shelter or evacuate in a flood, or how to recognize heat illness.

Engineering

Changing the physical conditions so the harm is less likely or less severe, whether or not anyone remembers the advice.

Fire service: installing ten-year sealed-battery alarms, or residential sprinklers in new construction.

All hazards: grab rails and improved lighting to prevent falls, or defensible space around a home in the wildland interface.

Enforcement

Applying the codes and rules that already exist, where they apply.

Fire service: inspecting the occupancies where a violation carries the most risk, and following through on what is found.

All hazards: property maintenance, housing and zoning codes, used with the agencies that own them.

Economic incentives

Making the safer choice affordable, or the unsafe one costly.

Fire service: grant-funded alarms for households who cannot buy them, or a rebate for a residential sprinkler system.

All hazards: subsidized home modification for older adults, or insurance recognition for wildfire mitigation.

Emergency response

Improving the response to the risk that remains after the other four have done what they can.

Fire service: moving a unit, changing a dispatch protocol, or adding a capability where the need is concentrated.

All hazards: community paramedicine for the households the other four have not reached.

Almost every program that has been shown to work combined several of these. Education alone changes what people know; it does not reliably change what happens to them.

What technology needs to solve

These are the operational problems departments actually describe. Each one opens onto the approaches that address it, and the products listed here that claim to.

Worth being clear about

Technology does not reduce risk by itself. It helps a department identify risk, coordinate interventions, document the work and find out whether those interventions changed the outcome.

A department with a clear problem and a spreadsheet will get further than a department with a platform and no question. Buy in that order.

Build a CRR starter plan

Four questions. It arranges your answers into the shape a CRR plan takes, so you have something to put in front of a chief, a council or a partner agency. Nothing you type is sent anywhere or saved.

What problem are you working on?

Step 1 of 4

What data could help you understand this problem?

Step 2 of 4

Tick what you could get hold of, not what you already have joined together.

Which kinds of intervention could change this outcome?

Step 3 of 4

More than one is usually the right answer. Education on its own rarely moves a number.

Fill in what you already know.

Step 4 of 4

The number as it stands today, before you do anything

What you will actually do

Who specifically, not the whole jurisdiction

Where specifically — a tract, a corridor, a set of addresses

Who else touches this problem

How much of the work got done

What changed for the people you targeted

Start with the data you already have

Departments often assume CRR begins with buying something. It usually begins with joining together records the department already holds and has never looked at side by side.

  • CAD — where you go, when, and how often
  • RMS and NERIS — what you found when you got there
  • EMS records — the demand nobody counts as fire risk
  • Inspection records — what has been checked, and what has not
  • Pre-incident plans
  • Fire investigations — the causes, which is the part that points at an intervention
  • Code enforcement actions
  • Smoke alarm installations, if anyone has kept the addresses
  • Community paramedicine contacts
  • Frequent caller information

Then the data your community already has

The second half is held by other people. Most of it is public, and the parts that are not are usually obtainable with an agreement rather than a purchase.

  • Census and American Community Survey — age, income, tenure, language, household composition
  • Social vulnerability data
  • Property and parcel records — building age, construction, ownership
  • Public health data
  • Transportation and crash data
  • School district information
  • Housing authority and code data
  • Hospital and health system data
  • Planning and zoning — what is being built, and where
  • Weather and environmental data

The value is in the join. Incident history says where things happened. Census and parcel data say who lives there and in what. Neither on its own tells you who to visit on Tuesday.

Before you join any of it together

Two datasets that are each unremarkable can identify a household when they are put together. Decide these things before the join, not after somebody asks.

  • Know which of your data is personally identifiable, and treat it that way
  • Know where HIPAA applies to what you hold, and get advice rather than assuming
  • Put a written data-sharing agreement in place before data crosses an agency boundary
  • Collect the least you need for the question you are asking
  • Give access by role, so a volunteer and an analyst do not see the same thing
  • Say who owns the joined dataset, who may query it, and how long it is kept
  • Decide how a household withdraws consent, and what happens to their record
  • Publish and share aggregates; keep the record-level data inside the agreement

This is a description of good practice, not legal advice. Your own counsel and your state law decide what applies to you.

Measure outcomes, not just activity

Activity measures say how much work was done. Outcome measures say whether anything changed for the people the work was aimed at. Departments need both, and almost always report only the first.

  • What we did

    We installed 2,000 smoke alarms.

    What changed

    Did residential fire injuries fall among the households we targeted?

  • What we did

    We completed 500 home safety visits.

    What changed

    Did repeat incidents decline at the addresses we visited?

  • What we did

    We inspected 1,200 occupancies.

    What changed

    Did high-risk violations decrease in that occupancy class?

  • What we did

    We taught 3,000 schoolchildren.

    What changed

    Did youth-set fires fall in the areas those schools serve?

  • What we did

    We ran a fall-prevention campaign.

    What changed

    Did fall-related 911 calls drop among the residents who took part?

The right-hand column is harder, slower and occasionally disappointing. It is also the only column that answers the question a council asks when the budget is tight.

The order that makes measurement possible

The reason most prevention work cannot show an outcome is that the first step was skipped, and by then it is too late to go back for it.

  1. Step 1 of 4Baseline

    Take the number before you start, for the population and area you are about to work in. Not the citywide number, and not last year's number for somewhere else.

  2. Step 2 of 4Intervention

    Do the work, and record what was actually delivered, to whom, and where. A program you cannot describe precisely cannot be evaluated.

  3. Step 3 of 4Measurement

    Compare against the baseline, over a period long enough for the number to mean something, and be honest about what else changed in that time.

  4. Step 4 of 4Adjustment

    Continue it, change it, expand it or stop it. Stopping something that did not work is a result, not a failure.

Preventing deaths and injuries from house fires: an outcome evaluation of a community-based smoke alarm installation programme

The outcome evaluation of Operation Installation in Dallas. Volunteers and firefighters canvassed 36 high-risk census tracts between 2001 and 2011; the study followed 8,134 programme houses against 24,346 non-programme houses in the same tracts.

Why it matters

Over a mean of 5.2 years, house fire deaths and injuries were 68% lower in programme houses (3.1 vs 9.6 per 100,000; rate ratio 0.32, 95% CI 0.10 to 0.84), and 63% lower after adjustment. It also found the effect fading after year six as alarms stopped working — which is the more useful half of the finding, and the half that gets left out of the slide.

Preventing deaths and injuries from house fires: a cost-benefit analysis of a community-based smoke alarm installation programme

What the same Dallas programme cost, and what it returned. Free to read in full.

Why it matters

Estimated net savings of $3.8 million over 2001-2011, a $3.21 return for every dollar spent from a societal perspective, and an incremental cost per fire injury averted of $128,800 counting only direct programme and medical costs. That last figure matters as much as the first: it is what the programme costs before you count lost productivity, and a council will ask.

Twelve years of the HomeSafe programme in Surrey, British Columbia, across 120,349 households, comparing each initiative against both the pre-intervention period and the city-wide trend.

Why it matters

It reports which parts worked and which did not. Firefighter home visits, alarm inspection and installation, and alarm checks at incidents were the three effective initiatives; door hangers and package distribution were not. Programmes that publish their failures are rarer than they should be, and more useful.

What good CRR looks like

Not a maturity model and not a score. A list you can hold your own program against, and a reasonable standard to hold a vendor to.

  • Risk is described with local data rather than assumptions
  • Risk can be examined at the neighborhood or address level where that is appropriate
  • High-risk populations are identified deliberately, not discovered by accident
  • Intervention decisions are tied to the risk that was identified
  • Prevention work is recorded somewhere that survives the person doing it
  • Partners are involved where they can influence the outcome
  • A baseline is taken before the program starts
  • Both activity and outcome measures are collected
  • Results are reviewed on a schedule, not when someone asks
  • Programs can be expanded, changed or stopped on the evidence
  • Data shared with health, housing or social services is governed by a written agreement
  • Personal information collected during prevention work is protected as carefully as patient data

CRR is not a program. It is a way of making decisions.

Start small

You do not need a data scientist, a new software platform or a fifty-page strategic plan to begin. You need one problem and the willingness to find out whether you changed it.

Pick the thing that keeps happening. Then work through these, in order, with whoever is in the room.

  • What keeps happening?
  • Who is being harmed?
  • Where is it happening?
  • What information do we already have about it?
  • Who else in this community knows something about this problem?
  • What could realistically change the outcome?
  • How would we know if it worked?

Then begin. The first cycle will be imperfect and will teach you more than the plan would have.
