Lead risk training

Lesson 1 • Lead's Physical and Chemical Properties

Covers atomic structure, density, melting point, and reactivity of lead compounds. Grounds later exposure pathway analysis in material science fundamentals.

Lesson 2 • Vulnerable Populations and Differential Risk

Identifies groups with heightened susceptibility, including children, pregnant individuals, and workers. Informs risk prioritisation decisions covered in later chapters.

Lesson 3 • History of Lead Use and Contamination

Traces industrial, residential, and consumer applications of lead across centuries. Contextualises current contamination patterns and legacy site challenges.

Lesson 1 • Disclosure and Notification Requirements

Covers mandatory disclosure obligations for property transactions and renovation projects. Connects legal duties to practical documentation workflows.

Lesson 2 • Enforcement Mechanisms and Liability

Examines how regulatory agencies investigate violations and impose penalties. Prepares students to advise clients on liability exposure and corrective action.

Lesson 3 • Overview of Lead Regulatory Programmes

Introduces the major regulatory programmes addressing lead in housing, workplaces, and the environment. Provides the governance structure underlying all compliance activities.

Lesson 4 • Permissible Exposure Limits and Action Levels

Defines numerical thresholds that trigger protective actions in occupational and residential settings. Students apply these benchmarks during risk assessment exercises.

Lesson 1 • Soil and Exterior Contamination

Analyses lead accumulation in soil from paint, exhaust, and industrial deposition. Connects soil pathways to ingestion and tracked-in dust exposure.

Lesson 2 • Occupational and Industrial Sources

Covers lead exposure in construction, manufacturing, firing ranges, and battery recycling. Prepares students to assess industrial hygiene controls in Chapter 5.

Lesson 3 • Consumer Products and Incidental Sources

Identifies lead in imported goods, traditional remedies, ceramics, and jewellery. Broadens the exposure inventory beyond structural sources.

Lesson 4 • Lead-Based Paint as a Primary Source

Examines deterioration mechanisms, friction surfaces, and impact zones that generate lead dust and chips. Establishes paint as the dominant residential exposure source.

Lesson 1 • Soil and Water Sampling

Details composite and discrete soil sampling grids and water first-draw protocols. Connects field collection to laboratory analysis and reporting.

Lesson 2 • Laboratory Analysis and Quality Assurance

Reviews analytical methods, detection limits, and QA/QC requirements for accredited labs. Equips students to evaluate lab reports and flag data quality issues.

Lesson 3 • Paint Chip and Dust Wipe Sampling

Teaches collection protocols for paint chip and dust wipe samples sent to accredited labs. Links sampling technique to data quality and defensible results.

Lesson 4 • X-Ray Fluorescence Testing

Explains XRF instrument operation, calibration, and reading interpretation for paint surveys. Addresses substrate interference and inconclusive result protocols.

Lesson 1 • Risk Characterisation and Uncertainty

Synthesises hazard and exposure data into a risk characterisation narrative with uncertainty bounds. Prepares students to communicate findings to non-technical audiences.

Lesson 2 • Exposure Assessment and Dose Estimation

Calculates exposure estimates using measured concentrations, contact rates, and body weight factors. Translates environmental data into predicted blood lead contributions.

Lesson 3 • Risk Assessment versus Inspection

Distinguishes the scope, purpose, and outputs of a risk assessment from a standard inspection. Clarifies when each approach is required by regulation or client need.

Lesson 4 • Risk Assessment Report Writing

Structures a compliant risk assessment report with findings, conclusions, and recommendations. Emphasises clarity, defensibility, and regulatory alignment.

Lesson 1 • Medical Surveillance and Biological Monitoring

Outlines blood lead monitoring schedules, medical removal triggers, and return-to-work criteria. Integrates occupational health data with exposure control decisions.

Lesson 2 • Respiratory Protection Selection

Guides selection of half-face, full-face, and supplied-air respirators based on exposure levels. Covers fit testing, maintenance, and storage requirements.

Lesson 3 • Worksite Containment and Hygiene

Covers negative pressure enclosures, critical barriers, and hygiene facility requirements. Prevents cross-contamination of clean areas during abatement operations.

Lesson 4 • Hierarchy of Controls for Lead Work

Applies elimination, substitution, engineering, administrative, and PPE controls in priority order. Establishes the decision framework used throughout this chapter.

Lesson 1 • Clearance Testing and Project Closeout

Defines clearance examination protocols, pass/fail criteria, and documentation requirements. Confirms that abatement achieves regulatory standards before occupant re-entry.

Lesson 2 • Interim Controls and Maintenance Strategies

Covers paint stabilisation, specialised cleaning, and friction surface repair as temporary measures. Establishes when interim controls are sufficient versus when abatement is required.

Lesson 3 • Paint Removal and Abatement Techniques

Details chemical stripping, heat removal, and mechanical methods for complete paint elimination. Emphasises dust generation controls critical to worker and occupant safety.

Lesson 4 • Encapsulation and Enclosure Methods

Explains approved encapsulant products and enclosure systems that isolate lead-based paint. Addresses durability requirements and re-inspection intervals.

Lesson 1 • Containment and Work Area Setup

Details interior and exterior containment configurations required before renovation begins. Ensures dust and debris are confined to the work area throughout the project.

Lesson 2 • Prohibited Practices and Dust Minimisation

Lists banned methods and specifies dust-minimising alternatives for cutting, sanding, and demolition. Reduces airborne lead generation at the source.

Lesson 3 • Post-Renovation Cleaning and Verification

Specifies the cleaning sequence, visual inspection, and verification testing required after renovation. Confirms the work area is safe before occupant re-entry.

Lesson 4 • Renovation Rule Applicability and Scope

Defines which structures, activities, and disturbed paint areas trigger lead-safe work practice requirements. Prevents common scoping errors that create compliance gaps.
