Lesson 2 • Personal Protective Equipment Selection

Details glove, goggle, face shield, and respiratory protection requirements by refrigerant type. Correct PPE selection directly reduces injury risk during handling tasks.

Lesson 3 • Workplace Safety Culture and Toolbox Talks

Builds habits of pre-task hazard reviews, peer accountability, and safety communication. A strong safety culture sustains compliance beyond formal training sessions.

Lesson 4 • Refrigerant Hazard Identification

Covers asphyxiation, frostbite, chemical burns, and flammability risks associated with refrigerants. Hazard awareness is the prerequisite for every safety decision in the field.

Lesson 1 • Transportation Regulations and Documentation

Covers vehicle loading, placarding, shipping papers, and quantity limits for transporting refrigerant cylinders. Compliance with transport rules avoids fines and ensures road safety.

Lesson 2 • Cylinder Types and Identification Markings

Explains color codes, DOT/UN markings, valve types, and tare weight labels on refrigerant cylinders. Correct identification prevents cross-contamination and dangerous misuse.

Lesson 3 • Storage Area Requirements

Details temperature limits, segregation rules, ventilation needs, and signage for refrigerant storage areas. Compliant storage prevents degradation, leaks, and regulatory violations.

Lesson 4 • Safe Cylinder Handling Techniques

Covers lifting, moving, and securing cylinders to prevent drops, valve damage, and leaks. Proper handling technique is the first line of defense against accidental release.

Lesson 1 • Handling Contaminated Refrigerants

Addresses identification, segregation, and labeling of contaminated or mixed refrigerants after recovery. Proper handling prevents reclamation rejection and protects downstream equipment.

Lesson 2 • Recovery Efficiency and Verification

Explains required recovery levels by equipment type and how to verify completion with vacuum testing. Meeting efficiency standards is a legal requirement and an environmental obligation.

Lesson 3 • Recovery Equipment Types and Selection

Compares push-pull, vapor-only, and liquid recovery machines and their appropriate applications. Selecting the right equipment reduces recovery time and protects system components.

Lesson 4 • Vapor and Liquid Recovery Techniques

Provides step-by-step procedures for vapor-only and liquid-first recovery methods. Mastering both techniques ensures efficient recovery across different system types and charge sizes.

Lesson 1 • On-Site Recycling Equipment and Procedures

Covers filter-drier use, oil separation, and multi-pass recycling to improve refrigerant purity. On-site recycling extends refrigerant life while keeping it within the same system.

Lesson 2 • Record-Keeping for Recycling and Reclamation

Covers required logs, transfer records, and retention periods for recycling and reclamation activities. Accurate records demonstrate regulatory compliance during audits and inspections.

Lesson 3 • Sending Refrigerant to Certified Reclaimers

Explains how to prepare, label, and ship refrigerant cylinders to certified reclamation facilities. Correct preparation ensures acceptance and prevents rejection or additional charges.

Lesson 4 • Recycling vs. Reclamation Defined

Clarifies the regulatory and technical distinctions between field recycling and certified reclamation. Understanding the difference determines which process is legally permitted in each situation.

Lesson 1 • Charging Methods and Equipment

Explains vapor charging, liquid charging, and weight-based charging using manifold gauges and scales. Method selection depends on refrigerant type, system design, and manufacturer specifications.

Lesson 2 • Pre-Charge System Preparation

Covers leak testing, evacuation, and moisture removal before introducing refrigerant. Thorough preparation prevents contamination and ensures accurate charge measurement.

Lesson 3 • Determining Correct Charge Amount

Teaches use of manufacturer data, superheat, subcooling, and sight glass methods to verify charge. Correct charge amount is critical for efficiency, reliability, and equipment longevity.

Lesson 4 • Charging Flammable and Low-GWP Refrigerants

Addresses special precautions for A2L and A3 refrigerants, including charge limits and ignition source control. Flammable refrigerant charging requires additional safety steps beyond standard procedures.

Lesson 1 • Leak Repair Techniques

Teaches brazing, flare replacement, valve core replacement, and coil repair methods. Selecting the correct repair technique ensures a durable, leak-free result.

Lesson 2 • Common Leak Locations and Root Causes

Identifies high-probability leak points including fittings, valves, coils, and brazed joints. Knowing common locations accelerates diagnosis and reduces unnecessary system disassembly.

Lesson 3 • Leak Detection Methods and Tools

Compares electronic detectors, UV dye, soap bubbles, and ultrasonic tools for leak detection. Each method has specific strengths suited to different system types and refrigerant classes.

Lesson 4 • Post-Repair Verification and Documentation

Explains pressure testing, leak re-check, and system performance verification after repairs. Complete documentation satisfies regulatory requirements and supports warranty claims.

Lesson 1 • Disposing of Non-Reclaimable Refrigerants

Explains destruction technologies, approved facility requirements, and documentation for disposing of unusable refrigerants. Proper destruction prevents illegal venting and environmental harm.

Lesson 2 • Refrigerant Oil and Waste Management

Covers handling, testing, and disposal of refrigerant-contaminated compressor oil as hazardous waste. Improper oil disposal creates environmental liability separate from refrigerant violations.

Lesson 3 • Regulatory Framework for Refrigerant Disposal

Covers venting prohibitions, disposal pathways, and enforcement mechanisms for refrigerant waste. Understanding the regulatory framework is the foundation for all compliant disposal decisions.

Lesson 4 • End-of-Life Equipment Decommissioning

Provides procedures for recovering refrigerant, draining oil, and preparing equipment for scrapping. Complete decommissioning prevents refrigerant release and meets extended producer obligations.
