Terms To Know

How to use this page

This page defines advanced terms you will see in proposals and reports. Each entry explains the term, what it means for your project, and when to call a pro. Use it to understand protocols, controls, and clearance before work begins.

Scan the sections below, open the term you heard on a call or in a report, and follow the service link if you need help now.

11 Types of Mycotoxins

One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin.

Mold

Here are some common terms you will see on mold projects. These definitions cover scope, controls, and clearance.

Mold Remediation Protocol (MRP)

  • Definition: A written scope that sets affected areas, methods, engineering controls, PPE, and clearance criteria.

  • What it means: Everyone follows the same playbook and the job is scoped once.

Mold

Here are some common terms you will see on mold projects. These definitions cover scope, controls, and clearance.

Post-Remediation
Verification (PRV)

  • Definition: Independent clearance that uses visual standards, moisture targets, and sampling to confirm results.

  • What it means: Documented proof the area is clean, dry, and ready for rebuild.

Mold

Here are some common terms you will see on mold projects. These definitions cover scope, controls, and clearance.

Containment

  • Definition: A sealed work zone with controlled entries and pressure control.

  • What it means: Prevents cross-contamination into occupied or clean areas.

Mold

Here are some common terms you will see on mold projects. These definitions cover scope, controls, and clearance.

Air Washing

  • Definition: Directed airflow and HEPA filtration used to purge airborne debris during or after work.

  • What it means: Reduces particle counts before PRV and speeds normalization.

Mold

Here are some common terms you will see on mold projects. These definitions cover scope, controls, and clearance.

Mycotoxins

  • Definition: Toxic metabolites produced by certain molds that can bind to dust and surfaces.

  • What it means: Indicates long-standing moisture and growth; cleaning must address residue and source.

Lead

Here are some common terms you will see on lead projects. These definitions cover RRP rules, cleanup, and clearance testing.

RRP Rule

  • Definition: Federal requirements for lead-safe renovation in pre-1978 buildings, including certification, containment, and HEPA cleanup.

  • What it means: Methods and documentation are prescribed, not optional.

Lead

Here are some common terms you will see on lead projects. These definitions cover RRP rules, cleanup, and clearance testing.

  • What it means: Verifies the space is safe to re-occupy.

Lead

Here are some common terms you will see on lead projects. These definitions cover RRP rules, cleanup, and clearance testing.

Lead Encapsulation

  • Definition: Approved coatings that lock down lead-based paint on sound substrates.

  • What it means: Durable control when removal is not practical, but surfaces must be prepped and maintained.

Lead

Here are some common terms you will see on lead projects. These definitions cover RRP rules, cleanup, and clearance testing.

Paint Stabilization

  • Definition: Repair, surface prep, and repaint to stop dust from deteriorated coatings.

  • What it means: Fast, budget-friendly control while planning long-term solutions.
