# Mold Assessment & Remediation Protocol (US) > Author the three regulated deliverables for a US licensed mold engagement: Mold Assessment Report, Mold Remediation Protocol (work plan with S520 containment level, engineering controls, PPE, scope of work, and pre-declared clearance criteria), and Post-Remediation Assessment / Verification Report. Aligned to IICRC S520 (with ANSI/IICRC S210 successor), EPA mold guidance, OSHA respiratory protection rules, and state regimes for TX (TDLR), FL (DBPR), and NY (DOL + NYC DOH). Tags: Environmental, Indoor Air Quality, Mold, IICRC S520, IICRC S500, Remediation, US Regulation, TDLR, DBPR, NYC DOH, Insurance Claims, Litigation ## Example Prompts - Draft a mold assessment report for a Texas water-loss claim with Condition 3 growth in the master bath - Write a mold remediation protocol with Full Containment for a 250 sq ft Condition 3 area in a Florida condominium - Produce a post-remediation verification report and Texas Certificate of Mold Damage Remediation - Author a NYC DOH Level III remediation protocol for a 45 sq ft basement growth area URL: https://rakenne.app/skills/mold-assessment-and-remediation-protocol/index.md Try this skill: https://rakenne.app/a/?skill=mold-assessment-and-remediation-protocol ## Overview In the United States, mold remediation is one of the few indoor-environment disciplines where the deliverable is legally gated by state licensure. A licensed Mold Assessment Consultant (TX), Mold Assessor (FL), or Mold Assessment Licensee (NY) authors the assessment and the remediation protocol; a separately licensed contractor executes the work; and a licensed assessor — independent of the contractor — issues the post-remediation document. This skill produces all three regulated deliverables, aligned to **IICRC S520** (with reference to its consolidated **ANSI/IICRC S210** successor) and to the operative state rules in Texas, Florida, and New York. ## What It Covers - **Mold Assessment Report** — building and water-loss history, room-by-room visual findings, moisture map, sampling plan with outdoor and unaffected-indoor reference samples, AIHA-LAP, LLC – EMLAP-accredited lab results, S520 Condition designations (1/2/3), separately recorded Moisture Conditions, vulnerable-population identification, and assessor credential block. - **Mold Remediation Protocol (Work Plan)** — affected-area inventory with material quantities, S520 containment level (Minimal / Limited / Full; NYC Levels I/II/III), HEPA-filtered negative air with continuously logged −0.02 in. WC differential, decontamination chamber, PPE per OSHA 29 CFR 1910.134, scope of work per material type with quantities, waste handling, occupant notification with vulnerable-population relocation trigger, **pre-declared clearance criteria locked before work commences** (visual, moisture, air sampling thresholds, analytical method per ASTM D7788), and — for Texas — mandatory estimated start and completion dates per 25 TAC §295.326. - **Post-Remediation Assessment / Verification Report** — independence statement, visual and moisture confirmation, sampling against the locked Protocol criteria (no after-the-fact threshold relaxation), pass/fail/re-clean directive, and the jurisdiction-correct closing form (TX Certificate of Mold Damage Remediation; FL clearance report; NY post-remediation evaluation; generic PRA per S520 §17). - **Domain guardrails** — refuses to render the credential page without state license number and expiry; flags assessor/remediator independence violations (FL F.S. §468.8411 threshold of $1,000; TX TDLR; NY Article 32); never specifies fogging as a substitute for physical removal; never uses "S1–S4" PPE labels (not S520); never maps S500 Cat to S520 Cond; documents ERMI/HERTSMI-2 only as informational, never as clearance metrics. ## Example Conversation > **You:** I'm a Texas MAC. We had a supply-line break in a master bath two weeks ago. Owner dried it with fans for three days, then re-occupied. Now they smell mold and we found visible growth on the back of the vanity and into the adjacent closet drywall. Approximately 35 sq ft of Condition 3 across the bathroom and closet. Owner is 71, has asthma. Need the protocol. > **Agent:** Texas MAC engagement, ~35 sq ft Condition 3 across two contiguous areas, vulnerable occupant (≥65 with asthma) — that triggers a mandatory relocation recommendation under 25 TAC §295.326. A few things I need to lock down before I draft the Protocol: > > 1. Containment level: at 35 sq ft and given the contiguous bathroom + closet with porous drywall to remove, I'm proposing **Limited Containment** under S520 (10–100 sq ft guidance), with HEPA-filtered negative air at −0.02 in. WC continuously logged, single-layer 6-mil critical barriers, and a 2-stage decon chamber. Want me to step up to Full given the vulnerable occupant, or hold at Limited with the relocation in place? > 2. Independence: confirm your firm will not also be the Mold Remediation Contractor on this project — TDLR rule, no common ownership. > 3. Clearance criteria — I'll lock these in the Protocol now and the PRV will evaluate against them as written. Air sampling per ASTM D7788 at an AIHA-LAP, LLC – EMLAP lab, with one outdoor and one unaffected-indoor reference (likely the living room). No marker amplification of *Stachybotrys*, *Chaetomium*, or dominant *Aspergillus/Penicillium* absent in references. Moisture: substrate ≤ baseline reading on the unaffected side. Acceptable? > 4. Estimated start and completion dates — TX 25 TAC §295.326(b) requires both in the protocol. What dates should I write in? > **You:** Hold at Limited; we'll relocate her to her daughter's house. We're independent — I never remediate. Lab is EMSL Houston. Start Monday Nov 4, complete Friday Nov 8. > **Agent:** Drafting the Protocol now. Containment: Limited, single-layer 6-mil critical barriers floor-to-ceiling, HEPA-filtered negative air with continuously logged −0.02 in. WC differential at intervals not exceeding 4 hours, 2-stage decon at the bathroom door. PPE: half-face APR with P100 cartridges, full-body suit with hood, sealed goggles, nitrile gloves taped to suit cuff (per S520 §14 + OSHA 29 CFR 1910.134 written respiratory program — confirm contractor has fit-test and medical evaluation records). Scope of work with material quantities: I'm enumerating linear feet of paper-faced gypsum to remove (porous), linear feet of 2x4 framing for HEPA-vacuum and damp-wipe (semi-porous), and the vanity (porous, remove). Antimicrobial only after physical removal and HEPA cleaning, no fogging. Waste: double-bagged 6-mil through decon. Locked clearance criteria as you described. Estimated start 2024-11-04, completion 2024-11-08. Vulnerable-population relocation recommendation: mandatory; relocation arranged to family residence for the duration of work plus 24 hours post-clearance. I'll generate the occupant notification letter alongside the protocol. ## Standards & Authorities - **IICRC S520** (3rd ed., 2015) — Standard for Professional Mold Remediation - **ANSI/IICRC S210** — consolidated successor standard - **IICRC S500** — Standard for Professional Water Damage Restoration (Cat 1/2/3 — independent axis from S520 Conditions) - **NYC DOH 2008** — Guidelines on Assessment and Remediation of Fungi in Indoor Environments - **EPA 402-K-01-001** — *Mold Remediation in Schools and Commercial Buildings* - **OSHA 29 CFR 1910.134** — Respiratory Protection (mandatory for any respirator above filtering-facepiece) - **AIHA** — *Recognition, Evaluation, and Control of Indoor Mold* (the "green book") - **ACGIH** — *Bioaerosols: Assessment and Control* - **ASTM D7788** — Standard Practice for Air Sampling of Fungi using Inertial Impaction Spore Traps ### State Regimes - **Texas TDLR** — 25 TAC Ch. 295 / Occupations Code Ch. 1958. MAC writes assessment + protocol; separate licensed Mold Remediation Contractor executes; MAC issues the Certificate of Mold Damage Remediation. Protocol must include estimated start/completion dates and vulnerable-population relocation recommendation when triggered. - **Florida DBPR** — Ch. 468 Pt. XVI F.S. + Rule 61-31 F.A.C. Licensed Mold Assessor authors assessment + protocol; licensed Mold Remediator executes; assessor independence required when remediation cost > $1,000 per F.S. §468.8411. - **New York DOL** — Article 32 (assessor / remediator / abatement worker licenses). Within NYC, the 2008 DOH Guidelines apply with Levels I/II/III at < 10 / 10–30 / > 30 sq ft thresholds. --- Back to [Skill Library](https://rakenne.app/skills/index.md)
