Laboratory Safety Course

Lesson 1 • Introduction to Lab Safety Culture

Defines safety culture and its impact on incident rates. Connects individual behavior to organizational outcomes and sets the tone for the entire course.

Lesson 2 • Hazard Recognition Fundamentals

Introduces the four major hazard categories found in labs. Students practice identifying hazards before learning control strategies in later chapters.

Lesson 3 • Emergency Contacts and Reporting

Covers incident reporting protocols and emergency communication chains. Timely, accurate reporting is the first step in preventing recurrence.

Lesson 4 • Safety Data Sheets and Labeling

Teaches interpretation of standardized chemical labels and safety data sheets. Accurate reading of these documents underpins all chemical handling decisions.

Lesson 1 • Body and Foot Protection

Reviews lab coats, aprons, and safety footwear standards for chemical and physical hazards. Material selection criteria are linked to SDS hazard data.

Lesson 2 • Eye and Face Protection

Covers safety glasses, goggles, and face shields for chemical splash, impact, and radiation hazards. Proper fit and anti-fog maintenance are emphasized.

Lesson 3 • Respiratory Protection

Distinguishes air-purifying from supplied-air respirators and explains fit-test requirements. Students match respirator type to airborne hazard concentration.

Lesson 4 • Glove Selection and Use

Addresses chemical resistance ratings, breakthrough times, and donning/doffing technique. Incorrect glove choice is a leading cause of skin exposure incidents.

Lesson 1 • Chemical Storage and Segregation

Teaches compatibility grouping, storage quantity limits, and ventilation requirements. Improper segregation is the primary cause of reactive chemical incidents.

Lesson 2 • Chemical Inventory and Procurement

Establishes procedures for maintaining an accurate chemical inventory and applying green chemistry principles at the procurement stage to minimize hazard introduction.

Lesson 3 • Safe Handling Techniques

Covers proper transfer, mixing, and dispensing methods for corrosives, flammables, and toxics. Technique errors are mapped to specific injury outcomes.

Lesson 4 • Fume Hoods and Ventilation Controls

Explains fume hood operation, face velocity requirements, and alarm response. Engineering controls are the primary defense before PPE is needed.

Lesson 1 • Biosafety Cabinets and Containment

Distinguishes Class I, II, and III biosafety cabinets and their appropriate applications. Correct cabinet selection is critical for both product and personnel protection.

Lesson 2 • Decontamination and Sterilization

Teaches autoclave operation, chemical disinfectant selection, and validation methods. Effective decontamination breaks the chain of infection transmission.

Lesson 3 • Biosafety Level Classification

Defines BSL-1 through BSL-4 requirements and the risk group system for biological agents. Classification drives all downstream containment and PPE decisions.

Lesson 4 • Standard Microbiological Practices

Covers aseptic technique, hand hygiene, and sharps safety as universal precautions. These practices apply at every biosafety level and reduce exposure risk.

Lesson 1 • Mechanical and Ergonomic Hazards

Identifies pinch points, rotating equipment, and repetitive-motion risks in lab workflows. Early ergonomic intervention prevents cumulative musculoskeletal disorders.

Lesson 2 • Compressed Gas and Pressure Systems

Addresses cylinder storage, regulator use, and pressure vessel inspection. Compressed gas failures can cause projectile and asphyxiation hazards simultaneously.

Lesson 3 • Noise and Vibration Exposure

Quantifies permissible noise exposure limits and introduces hearing conservation program elements. Chronic exposure causes irreversible hearing loss without early intervention.

Lesson 4 • Thermal Hazard Control

Covers burns from hot plates, autoclaves, cryogenic liquids, and open flames. Temperature extremes require distinct PPE and handling procedures.

Lesson 1 • Radiation Detection and Dosimetry

Covers Geiger-Müller counters, scintillation detectors, and personal dosimeters. Accurate detection is prerequisite to verifying that controls are working effectively.

Lesson 2 • ALARA Principle and Dose Limits

Applies time, distance, and shielding strategies to minimize occupational dose. Regulatory dose limits define the upper boundary; ALARA targets well below them.

Lesson 3 • Radioactive Material Handling

Teaches receipt, use, and transfer procedures for radioactive materials in licensed labs. Proper technique prevents surface contamination and internal exposure.

Lesson 4 • Non-Ionizing Radiation Hazards

Addresses UV, laser, and radiofrequency radiation hazards and their specific controls. Non-ionizing sources are often underestimated but cause significant eye and skin injury.

Lesson 1 • Chemical Spill Response

Classifies spills by size and hazard level and prescribes appropriate response actions. Students distinguish incidental spills from emergency-level releases requiring evacuation.

Lesson 2 • Emergency Action Plan Essentials

Outlines required elements of a laboratory emergency action plan and evacuation procedures. A documented plan ensures consistent response regardless of who is present.

Lesson 3 • Fire Prevention and Response

Covers fire triangle principles, fire extinguisher classes, and lab-specific ignition sources. Students practice PASS technique and learn when to evacuate rather than fight.

Lesson 4 • First Aid for Lab Injuries

Addresses chemical burns, eye exposure, cuts, and inhalation injuries with immediate care steps. First aid knowledge bridges the gap until professional medical help arrives.

Lesson 1 • Laboratory Safety Program Design

Outlines the components of a written laboratory safety program aligned with recognized management system standards. A structured program ensures consistent hazard control across all lab activities.

Lesson 2 • Safety Metrics and Continuous Improvement

Defines leading and lagging safety indicators and links them to program improvement cycles. Data-driven decisions sustain and elevate safety performance beyond compliance.

Lesson 3 • Safety Inspection and Auditing

Teaches inspection checklist design, audit protocols, and finding classification. Regular audits verify that controls identified in earlier chapters remain effective over time.

Lesson 4 • Incident Investigation Techniques

Introduces root cause analysis methods including fault tree and fishbone diagrams. Thorough investigation transforms incidents into actionable system improvements.
