Chapter 34 Exercises: Hazardous Materials — Lead, Asbestos, Radon, and Mold

Exercise 34-1: Establish Your Home's Hazmat Profile

Objective: Create a hazardous material risk assessment for your specific home.

Steps: 1. Record your home's year of construction. 2. Based on the construction year, complete the following risk assessment checklist:

3. For each "High" or "Possible" category, note whether you have tested, have documentation, or have confirmed the material's presence or absence.

Deliverable: A completed risk assessment table that serves as the starting point for informed management decisions.

Exercise 34-2: Lead Paint Test Planning

Objective: Plan a lead paint testing strategy for any pre-1978 renovation work.

Scenario: You plan to renovate a room in a home built in 1965. The room has multiple layers of paint on walls, trim, and the ceiling. You want to strip the trim to bare wood.

Steps: 1. Identify which surfaces will be disturbed by your planned work. 2. Determine which test method (XRF, paint chip sampling, or DIY kit) is appropriate given your budget and timeline. 3. Research the cost of a certified lead inspector in your area (call two and get quotes). 4. Determine whether the EPA's RRP Rule would apply to your household for this project. 5. Outline the lead-safe work practices you would need to follow if lead is present.

Deliverable: A one-page test-and-safety plan for your renovation project.

Exercise 34-3: Radon Test — Do It

Objective: Actually test your home for radon.

Steps: 1. Purchase a short-term radon test kit ($15–$30 at most hardware stores or online from National Radon Program Services at sosradon.org). 2. Place it in the lowest level of your home that is regularly occupied (or the lowest livable level if the basement is used at least 6 hours per week). 3. Follow the manufacturer's placement and testing protocol (close windows and doors 12 hours before and during the test). 4. Mail the test device to the lab after the required exposure time (typically 48–96 hours). 5. Receive and record your results. 6. If results are at or above 4 pCi/L, research mitigation options and get at least two quotes from certified radon mitigators.

Deliverable: Your actual radon test result, and — if above 4 pCi/L — a mitigation plan with two contractor quotes.

Why This Is Non-Negotiable: Radon is the second leading cause of lung cancer. The test costs $15 and takes four minutes to set up. There is no legitimate reason to defer this exercise.

Exercise 34-4: Visual Asbestos Survey

Objective: Conduct a systematic visual survey of your home for suspect asbestos-containing materials.

Important Caveat: This exercise involves looking, not touching or disturbing any materials. If you find suspect materials, do not sample them yourself — hire a certified asbestos inspector.

Steps: Using the list of common asbestos locations from Section 34.3, survey your home:

1. Floors: Check for 9-inch or 12-inch floor tiles, especially under newer flooring or in unfinished areas. Note any visible adhesive (black mastic is particularly suspect).
2. Ceilings: Check for spray-applied texture (popcorn ceiling). When was your home built?
3. Pipes: Inspect visible pipe insulation in basement, crawlspace, or mechanical room. Note color, condition, and whether it appears fibrous or corrugated.
4. Walls: Check for troweled-on texture that might be asbestos-containing joint compound.
5. Exterior: Examine exterior siding for flat, cement-like panels or corrugated material.
6. Mechanical: Inspect insulation around boiler, furnace, and ductwork.

Deliverable: A room-by-room visual survey noting each suspect material, its location, its apparent condition (intact vs. damaged), and whether you plan to disturb it.

Exercise 34-5: Find Your Local Certified Professionals

Objective: Build a reference list of certified hazmat professionals in your area before you need them.

Steps: 1. Use the EPA's RRP-certified firm locator at epa.gov/lead/find-certified-firm-your-area to find three lead-certified firms within 30 miles of your home. 2. Use your state's environmental department website to find three licensed asbestos inspectors (not abatement contractors — inspectors) in your area. 3. Use the National Radon Proficiency Program (nrpp.info) or National Radon Safety Board (nrsb.org) locator to find two certified radon mitigators in your area. 4. Record names, phone numbers, and certification numbers for each.

Deliverable: A "Hazmat Professional Reference List" with at least eight contractors across the four hazard categories, verified as currently licensed/certified.

Exercise 34-6: Evaluate a Real Estate Disclosure Form

Objective: Understand how hazardous material disclosure works in real estate transactions.

Steps: 1. Obtain your state's standard real estate disclosure form (available from your state realtor association's website or a real estate attorney's office). 2. Identify all questions related to: lead paint, asbestos, radon, mold, and water intrusion. 3. For each disclosure item, answer the questions as they would apply to your current home (if you own) or evaluate how you would answer them for a hypothetical purchase of a pre-1978 home. 4. Note: Which questions require you to disclose the history of a problem even if it has been remediated?

Deliverable: A completed disclosure form (for exercise purposes) with notes on any questions whose implications surprised you.

Exercise 34-7: Moisture Audit for Mold Prevention

Objective: Identify moisture risk factors in your home before they become mold problems.

Steps: Conduct a moisture audit using the following checklist:

Bathroom: - Is the exhaust fan vented to the exterior (not into the attic or crawlspace)? - Is caulking around the tub/shower intact? - Any visible mold on grout, caulk, or drywall? - Does the fan run for at least 30 minutes after a shower?

Basement/Crawlspace: - Any visible water stains on walls or floor? - Any efflorescence (white mineral deposits) on masonry walls? - Any musty odor? - Is a vapor barrier installed in the crawlspace?

Kitchen: - Is the range hood vented to the exterior? - Any evidence of past leaks under the sink or dishwasher?

Attic: - Are bathroom and kitchen exhaust fans vented to the exterior (not into the attic)? - Any visible moisture or mold on the underside of roof sheathing?

Exterior: - Are gutters clean and directing water away from the foundation? - Is grading sloped away from the house for at least 6 feet?

Deliverable: A completed moisture audit checklist with notes on any items that need correction, prioritized by severity.

Exercise 34-8: Mold Remediation Scope Definition

Objective: Practice defining an appropriate scope of work for a hypothetical mold situation.

Scenario: You discover mold in two places: (1) a 2-inch by 6-inch patch on the grout in your shower, and (2) mold covering approximately 40 square feet of drywall in your basement, located behind a bookshelf near an exterior wall. The basement has had a persistent musty smell.

For each situation: 1. Classify the mold by EPA guidance on area (is this a DIY or professional situation?) 2. Identify what you would need to investigate to find and fix the moisture source before any remediation. 3. Describe the appropriate remediation approach (clean vs. remove; what materials). 4. Identify whether post-remediation air testing is warranted. 5. Estimate the cost range.

Deliverable: Two separate mold assessment memos — one for the shower, one for the basement — each addressing the four questions above.

Exercise 34-9: Research Your Water Supply for Lead

Objective: Determine whether your water supply system includes lead components.

Steps: 1. Contact your water utility and ask: "Is my service line lead or copper? When was it installed?" Many utilities maintain service line material databases. 2. If you have copper supply pipes inside the home, ask: "Were lead-tin solder connections standard practice for homes built in [your year] in your service area?" 3. Request any free lead testing your utility may offer (many do under EPA Lead and Copper Rule requirements). 4. If your utility doesn't offer free testing, research NSF/ANSI 53-certified lead filters appropriate for your tap configuration.

Deliverable: A summary of your water supply system's lead risk profile and any actions you plan to take.

Exercise 34-10: Create a Hazmat Disclosure Package

Objective: Prepare all existing hazardous material documentation in a format ready for future real estate disclosure.

Steps: 1. Gather all existing hazmat documentation: lead inspections, asbestos surveys, radon tests, remediation records, mold assessments, water quality tests. 2. For each document, note the date, testing entity, result, and any action taken. 3. For any known hazardous material issue that was remediated, document the remediation: contractor, scope of work, date, and any clearance testing results. 4. Create a cover document summarizing all findings and actions taken. 5. Store the package with your home's permanent records.

Deliverable: A complete hazardous material documentation package suitable for inclusion in a future seller's disclosure packet.
