Study Notes

Mold Cleanup

Hire a professional for mold infestations larger than 10 square feet.
For smaller areas (<10 sq ft), DIY cleanup is often possible, following recommended techniques.
If the HVAC system is suspected of mold contamination, consult the EPA guide "Should You Have the Air Ducts in Your Home Cleaned?" before acting.
Do not operate a contaminated HVAC system; this spreads mold.
For sewage-related water/mold damage, contact a specialist in contaminated water cleanup.
Consult a healthcare professional if health concerns arise before beginning cleanup.

Mold Testing & Sampling

Mold sampling is usually unnecessary if visible mold growth exists.
There are no federal mold or spore limits; sampling doesn't check federal standards compliance.
Surface sampling helps determine adequate remediation.
Professional mold sampling is recommended, adhering to AIHA or ACGIH guidelines.
No EPA regulations or standards exist for airborne mold contaminants.

Mold Prevention

Mold indicates moisture problems (leaks, past flooding, etc.).
Inspect buildings for water damage and visible mold.
Address and prevent conditions causing mold growth.
Use mold inhibitors in paints.
Employ air conditioners or dehumidifiers during humid periods.
Ensure adequate ventilation (kitchen/bathroom exhaust fans).
Maintain indoor humidity below 50%.

Methamphetamine Contamination

Methamphetamine is a highly addictive stimulant.
It's produced in superlabs (domestic and Mexico) and small clandestine labs.
Production involves hazardous chemicals persistent in the environment after cleanup.
Wyoming lacks mandatory disclosure or cleanup requirements for meth labs.
Health hazards from improper meth lab cleanup include decreased mental function, breathing problems, vomiting, nose/throat issues, lung damage, and chemical burns.
Cleanup steps: determine meth production history, ventilate, remove items, clean surfaces, clean ventilation, and engage professional plumbing/ductwork cleaning. Consult professionals if odor/staining persists.

Lead-Based Paint

Lead-based paint is common in homes built before 1978.
Disclosure is crucial for risk management; always include lead-based paint disclosure forms in transactions regardless of construction date.
Provide buyers/tenants with the EPA pamphlet "Protect Your Family From Lead in Your Home".
Lead paint issues depend on condition (cracking, peeling, area size, encapsulation possibility, financing type).

Radon

Radon is a colorless, odorless, tasteless radioactive gas from uranium in soil.
Homes are at risk regardless of age, condition, or presence of basement.
Radon buildup is a health concern; higher levels in older homes, poorly ventilated homes, and those built in areas with high uranium content.
Radon exposure damages lung cells, increasing lung cancer risk (a leading cause of cancer deaths in Wyoming).
Radon home test kits are available online (for Wyoming addresses) from Alpha Energy Laboratories, Air Chek Laboratories, and the Wyoming Radon Program (307-777-6015).
Radon levels (pCi/L): 4.0 average outdoor level; 1.3 average indoor; 4.0 pCi/L or higher needs immediate remediation; 2.0–4.0 pCi/L needs prompt action.

Asbestos

Asbestos is a mineral fiber used in various construction and manufacturing products (insulation, fire retardant).
Locations: attic/wall insulation, floor/ceiling tiles, roofing/siding, paint, pipes, furnaces, fabrics, automotive parts.
Exposure occurs when asbestos-containing materials are disturbed.
Asbestos exposure increases lung disease risk (worsened by smoking). Increased exposure increases risk.

Asbestos Locations in Homes

Attic and wall insulation (vermiculite)
Vinyl floor tiles, backing, and adhesives
Roofing and siding shingles
Textured paint and patching compounds
Areas around wood-burning stoves (paper, millboard, cement sheets)
Hot water and steam pipes (coating, blankets, tape)
Oil and coal furnaces and door gaskets
Heat-resistant fabrics
Automobile clutches and brakes

Asbestos Exposure

Exposure occurs when asbestos-containing material is disturbed, releasing fibers into the air.
Activities like demolition, home maintenance, and remodeling can cause disturbance.

Health Effects of Asbestos Exposure

Increased risk of lung disease, worsened by smoking.
Risk increases with exposure level.
Symptoms can take many years to develop.
Conditions can be difficult to identify.
Diagnosis involves medical history, physical examination, chest x-ray, and pulmonary function tests.
Major health effects: lung cancer, mesothelioma, asbestosis.

Identifying Asbestos-Containing Materials

Cannot be reliably identified visually unless labeled.
When in doubt, treat material as if it contains asbestos.

Home Inspection for Asbestos

Recommended before remodeling or if building materials are damaged (crumbling drywall, insulation).
Sampling should be done by a trained professional due to potential health risks from fiber release.
Self-sampling is not recommended.

Asbestos in Good Condition

Undamaged, undisturbed asbestos-containing materials are usually not a health risk.
Leave alone if in good condition.

What to Do if You Find Asbestos

Don't panic; undamaged material poses minimal risk.
Regularly inspect for wear or damage (tears, abrasions, water damage).
Avoid touching suspected material.
Limit access to slightly damaged areas; don't disturb.
For significant damage or planned renovations, hire a trained asbestos professional for repair or removal.

Asbestos Do's and Don'ts

Do's:*
Leave undamaged asbestos alone.
Minimize activity near damaged material; restrict children's access.
Avoid damaging asbestos-containing materials.
Hire trained professionals for removal and major repairs; also consider for minor repairs and sampling.
Don'ts:*
Dust, sweep, or vacuum asbestos debris.
Saw, sand, scrape, or drill asbestos materials.
Use abrasive tools on asbestos flooring.
Sand or level asbestos flooring; cover with new flooring if replacing.
Track asbestos material through the house; use wet mops for cleanup.

Asbestos Repair and Removal

Repair: Sealing (encapsulation) or covering (enclosure) to prevent fiber release. Done by trained professionals.
Removal: Necessary for extensive damage or when remodeling disturbs material. Must be done by a trained professional to avoid increasing exposure.

Asbestos Professionals

Inspectors: Inspect, assess conditions, sample materials, advise on corrections, monitor cleanup.
Contractors: Repair or remove asbestos materials.
While not always federally mandated for single-family homes, state and local requirements vary; always prioritize trained and accredited professionals for safety.

Hiring an Asbestos Professional

Avoid conflicts of interest (separate assessment and remediation firms).
Verify professional training and accreditation.
Check past performance with relevant agencies (air pollution control, worker safety, Better Business Bureau).

Pre- and Post-Work Steps for Contractors

Pre-work: Obtain a written contract outlining work plan, cleanup, and relevant regulations.
Post-work: Obtain written assurance of procedure adherence. Ensure proper cleanup, disposal (sealed, labeled bags), and wet cleaning methods (wet mops, HEPA vacuums). Air monitoring may be necessary.
