Safety Training

Safety training is the administrative backbone of laboratory operations. Under the Occupational Safety and Health Administration (OSHA) mandates and accreditation standards (CAP, TJC), employers are legally required to provide a safe workplace. This is achieved through rigorous, documented training programs that ensure every employee recognizes hazards and knows how to mitigate them. In a Cytogenetics laboratory, where staff handle fresh human tissue, hazardous solvents, and sharps daily, training is not a one-time event but a continuous cycle of education

Training Frequency & Mandates

Training must be timely and recurring to ensure information retention and compliance with changing regulations

  • Initial Training (Orientation): Must occur before the employee performs any duties involving exposure to hazards. A new laboratory scientist cannot handle a bone marrow specimen until they have been trained on Bloodborne Pathogens
  • Annual Retraining: OSHA requires specific modules (e.g., Bloodborne Pathogens, Fire Safety) to be reviewed annually
  • Procedural Changes: Whenever a new hazard is introduced (e.g., a new chemical fixative or a new automated harvester), specific training on that hazard must be conducted immediately
  • Remedial Training: If an accident occurs or an audit reveals a deficiency (e.g., staff caught not wearing lab coats), targeted retraining is required as part of the corrective action

Biological Hazard Training (Bloodborne Pathogens Standard)

The OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030) is the primary curriculum for biological safety. Training focuses on the concept that all human blood and tissue are potentially infectious

  • Universal/Standard Precautions: Training enforces the mindset that every sample (HIV positive or not) is treated with the same high level of caution
  • Hepatitis B Vaccination
    • Employers must offer the Hepatitis B vaccination series free of charge: to all employees with occupational exposure risk within 10 days of initial assignment
    • Training must explain the efficacy and safety of the vaccine
    • If an employee declines, they must sign a mandatory Declination Form, though they can opt to take the vaccine later
  • Exposure Control Plan (ECP): Staff must be trained on the lab’s specific written ECP, which details:
    • Who is at risk
    • How to minimize exposure (Engineering controls vs. Work practice controls)
    • Post-exposure evaluation and follow-up procedures (what to do if a needlestick occurs)

Chemical Hazard Training (Hazard Communication)

Under the “Right to Understand” laws (Hazard Communication Standard), staff must be trained to handle the specific chemical inventory of the cytogenetics lab

  • Safety Data Sheets (SDS): Training includes how to find and read an SDS. Staff must be able to locate the “First Aid” (Section 4) and “Spill Measure” (Section 6) sections quickly during an emergency
  • Labeling Systems: Laboratory scientistsare trained on the Globally Harmonized System (GHS) of classification. They must memorize the meaning of pictograms (e.g., the “Exclamation Mark” for irritants, the “Flame” for flammables like Methanol, and the “Corrosion” symbol for Acids)
  • Specific Cytogenetic Risks
    • Teratogens: Special training is often required for handling Formamide (used in FISH), as it poses reproductive risks. Pregnant staff may require job modifications, and all staff must understand these risks
    • Chemical Hood Operation: Training on how to verify that the fume hood is drawing air correctly before mixing fixatives

Fire & Emergency Training

Fire safety training moves beyond theory into practical application. Accreditation agencies often require that staff can demonstrate knowledge of the specific fire response plan

  • The Acronyms: Staff must memorize and understand:
    • RACE: Rescue, Alarm, Contain, Extinguish/Evacuate
    • PASS: Pull, Aim, Squeeze, Sweep (for extinguisher use)
  • Drills: Periodic fire drills are conducted to ensure staff know the location of the nearest pull station, extinguisher, and evacuation assembly point
  • Specialized Hazards
    • Liquid Nitrogen (\(LN_2\)): If the lab stores cells in liquid nitrogen, staff must be trained on the risks of asphyxiation (oxygen displacement) and cryogenic burns. Training includes the use of thermal gloves and face shields during tank filling

Waste Management Training

Proper disposal is a legal requirement enforced by the EPA and local authorities. Training ensures staff do not inadvertently mix waste streams, which can result in massive fines or injury

  • Segregation
    • Training teaches the difference between “Clean Glass” (cardboard box) and “Contaminated Sharps” (red rigid container)
    • Staff learn that chemical waste (Methanol/Xylene) must never be poured down the sink
  • Sharps Safety
    • Specific training on the “No Recap” rule for needles
    • Safe operation of scalpel blade removers or retractable devices used in tissue culture

Documentation of Training

Regulatory bodies (CAP/CLIA) operate on the principle: “If it wasn’t documented, it wasn’t done.”

  • Sign-Off Sheets: Every training session requires a physical or digital signature confirming attendance
  • Competency Assessment: Training is often followed by a quiz or a direct observation (competency assessment) to verify that the employee understood the material
  • Record Retention: Training records are typically kept in the employee’s personnel file for the duration of employment plus a specified period (often 3 to 30 years depending on the type of exposure training)
