Chapter 35 Exercises: Fire Safety — Detection, Suppression, and Egress

Exercise 35-1: Smoke Detector Audit

Objective: Assess the current state of smoke detection in your home against code-minimum and best-practice standards.

Steps: 1. Walk your home and locate every smoke detector. Record for each: - Location (room, wall vs. ceiling, proximity to sleeping areas) - Type (ionization, photoelectric, combination — check the back of the unit for labeling) - Manufacturing date (printed on back — replace if over 10 years old) - Battery status (test with the test button) - Interconnected or standalone?

2. Map your home's floor plan and mark each detector's location.

3. Compare your inventory against requirements: - Is there a detector inside every bedroom? - Is there a detector outside every sleeping area? - Is there a detector on every level including basement?

4. Note any gaps, outdated units (over 10 years), or locations where ionization-only units are installed in sleeping areas.

Deliverable: A completed smoke detector audit with a list of actions needed: replacements, additions, or upgrades to combination units.

Exercise 35-2: Carbon Monoxide Detector Assessment

Objective: Verify appropriate CO detection for your home's fuel-burning appliances.

Steps: 1. List all fuel-burning appliances in your home: gas furnace, gas water heater, gas range, oil boiler, wood-burning fireplace, gas dryer. 2. Note whether you have an attached garage. 3. Locate all CO detectors and record their locations. 4. Assess: Is there a CO detector outside each sleeping area? Is there one on every level? 5. If you have a gas range or cooktop: is the nearest CO detector at least 15 feet away (to prevent nuisance alarms from cooking)? 6. Check the manufacturing date on each unit — CO sensors have a service life typically of 5–7 years.

Deliverable: A CO detector placement map with upgrade recommendations.

Exercise 35-3: Fire Extinguisher Inspection

Objective: Verify that your fire extinguishers are properly sized, accessible, and maintained.

Steps: 1. Locate all fire extinguishers in your home. 2. For each, record: - Rating (ABC, BC, K, etc.) - Size (weight of agent) - Pressure gauge reading (green zone = OK; red = needs service or replacement) - Last inspection or service date (printed on tag or from memory) - Accessibility (can you reach it in under 10 seconds without moving anything?) 3. Evaluate whether you have adequate coverage: - At minimum: kitchen - Recommended: garage, mechanical/basement 4. Practice the PASS technique (without discharging the extinguisher): Pull, Aim, Squeeze, Sweep.

Deliverable: An extinguisher inventory with any needed replacements, recharges, or additions noted. If you currently have no extinguisher in the kitchen, purchase one this week.

Exercise 35-4: Egress Window Measurement

Objective: Verify that all sleeping room windows meet egress requirements.

Steps: For each sleeping room in your home (including basement bedrooms): 1. Identify the egress window (the window that would serve as an emergency escape). 2. Open the window fully. 3. Measure the net clear opening: - Width (inside the frame, with window fully open) - Height (inside the frame, with window fully open) - Calculate area: width × height = _ sq in ÷ 144 = _ sq ft 4. Measure the sill height above the finished floor. 5. Compare against requirements: - Minimum area: 5.7 sq ft (5.0 sq ft for grade-level) - Minimum width: 20 inches - Minimum height: 24 inches - Maximum sill height: 44 inches

6. Record results for each bedroom.

Deliverable: A bedroom egress window compliance table. For any non-compliant window, research replacement options and get one quote for a compliant replacement.

Exercise 35-5: Fire Escape Plan

Objective: Create and practice a documented fire escape plan for your household.

Steps: 1. Draw a floor plan sketch of your home showing all rooms, doors, windows, and stairs. 2. For each bedroom, mark: - Primary exit (door to hallway) - Secondary exit (egress window) 3. Plot two escape routes from each sleeping room to the exterior. 4. Designate a meeting place outside (specific location, not just "outside"). 5. Assign a "caller" responsibility (who calls 911 once outside). 6. Practice: - Conduct a daytime walkthrough with all household members - Conduct a nighttime drill (in the dark) — navigate primary routes without lights - Practice operating the egress window (especially if it sticks or is difficult to open) 7. Schedule the next practice drill (at least annually).

Deliverable: A written fire escape plan with the floor plan sketch, posted inside the home where all household members will see it. A dated record of the practice drill.

Exercise 35-6: Garage Fire Separation Check

Objective: Verify that the fire separation between your attached garage and living space meets code requirements.

Steps: 1. Locate the door between your attached garage and living space. 2. Check: - Is the door solid wood or solid/honeycomb steel (minimum 1-3/8" thick)? Or is it a hollow-core interior door? - Does it close automatically when released? (Test: push it open, release it — does it swing shut and latch without you touching it?) - Does it latch automatically? (Does the latch engage when the door closes?) 3. Inspect the wall between the garage and living space (if accessible from the garage side): - Is there drywall on the garage side of the wall? - Are there any obvious penetrations (pipe holes, gaps at the top or bottom of the wall) that are not sealed? 4. Check any pipes or wires that pass from the garage into the living space — are they sealed with fire caulk or another fire-stop material?

Deliverable: A garage fire separation checklist with any deficiencies noted. If the door doesn't self-close and self-latch, this is a safety deficiency that should be corrected immediately — self-closing hinges are a $25 fix.

Exercise 35-7: Wildfire Risk Assessment (If Applicable)

Objective: For homeowners in fire-prone regions, assess defensible space and construction vulnerabilities.

Note: This exercise is most relevant for homes in WUI (wildland-urban interface) zones. If you live in a dense urban area with no wildfire risk, skip to Exercise 35-8.

Steps: 1. Look up your property on the USFS or CAL FIRE fire hazard severity zone map. 2. Walk your Zone 1 (0–30 feet from the structure): - Any dead vegetation? Dead wood within 30 feet of the structure? - Any combustible stored materials (firewood, propane tanks, furniture) within 5 feet of the house? - Are there tree branches within 10 feet of the roof? 3. Inspect vents: - Attic vents, soffit vents, foundation vents — what size mesh is the screening? - 1/4-inch mesh (standard) allows ember entry; 1/16-inch mesh does not. 4. Assess decking material — combustible (wood) or ember-resistant (concrete, metal, ember-rated composite)? 5. Assess roof covering — Class A, B, or C?

Deliverable: A Zone 1 checklist and a priority action list for your highest-risk vulnerabilities.

Exercise 35-8: Carbon Monoxide Emergency Protocol

Objective: Ensure all household members know the correct response to a CO alarm.

Steps: 1. Gather all household members. 2. Review: What does a CO alarm sound like versus a smoke alarm? (Test both so they know the difference.) 3. Walk through the protocol: - When CO alarm sounds: everyone leaves immediately — no stopping for belongings - Designate the meeting point (same as fire escape plan) - Call 911 from outside - Describe any symptoms to the 911 operator - Do not re-enter until cleared by emergency services 4. Discuss: If someone cannot be roused (unconscious), the caller should state this to 911 immediately and describe the location within the home. 5. Test your CO detector using the test button so everyone recognizes the sound.

Deliverable: Written CO protocol posted with fire escape plan. Confirmation that all household members know the sound of the CO alarm.

Exercise 35-9: Sprinkler System Awareness (New Construction or Renovation Planning)

Objective: Understand sprinkler requirements and costs if you are planning new construction or a major addition.

Steps: 1. Determine whether your jurisdiction requires residential fire sprinklers in new construction or additions (check with your building department — see Chapter 33). 2. If sprinklers are not required but you are planning new construction: request a quote from a licensed sprinkler contractor for a residential system. Get a cost-per-square-foot figure. 3. Research your homeowner's insurance policy for any discount offered for homes with residential sprinklers. 4. Calculate: sprinkler installation cost vs. lifetime insurance savings.

Deliverable: A cost-benefit summary for sprinkler installation in your planned project.

Exercise 35-10: Night Fire Drill

Objective: Experience what fire escape in the dark actually feels like, with all household members.

Steps: 1. Schedule the drill and tell all household members it's happening (don't do a nighttime drill without warning for households with children — the goal is practice, not panic). 2. Turn off all lights in the home. 3. Start the timer. 4. Have each household member navigate from their bedroom to the exterior meeting point — using only their practiced knowledge of the route, not turning on lights. 5. Time how long it takes. 6. Identify any navigation challenges encountered (unfamiliar obstacles, difficulty with egress window, confusion about direction). 7. Correct the issues: clear obstacles, practice the window operation, improve route familiarity. 8. Repeat until each household member can navigate from bedroom to meeting point in under 2 minutes.

Deliverable: A drill log with times for each participant and notes on obstacles or difficulties encountered. A schedule for the next drill.
