Study Notes
Hematology
- Hematology studies blood, focusing on its development, function, and diseases.
- It plays a crucial role in establishing, confirming, and ruling out hematological disorders.
- Common procedures include the Complete Blood Cell Count (CBC), assessing red blood cells, white blood cells, and platelets.
OSHA Standards
- OSHA mandates warning labels and protective measures to ensure workers are aware of potential hazards.
- Ensures safe working conditions in clinical laboratories through established safety standards.
- Requires the implementation of a Chemical Hygiene Plan (CHP) and Exposure Control Plan.
Safety Officer Role
- A designated safety officer oversees compliance with laboratory regulations and safety protocols.
- Responsibilities include ensuring proper labeling of chemicals and safe disposal of biohazardous materials.
Biohazard Exposure Prevention
- Blood is a significant source of bloodborne pathogens such as HIV and HBV in occupational settings.
- Occupational exposure includes percutaneous injuries, mucous membrane contact, and prolonged exposure to body fluids.
Sharps Disposal
- OSHA and CLSI require puncture-resistant sharps containers to eliminate risks associated with needle and sharp object transport.
- These containers should be readily available in patient areas and laboratories.
Hepatitis B Vaccination
- Employers are mandated to offer Hepatitis B vaccination to employees with potential blood exposure.
- Vaccination is a vital preventative measure against bloodborne pathogen exposure.
Standard Precautions
- Treat all human blood and body fluids as potentially infectious to prevent occupational exposure to pathogens.
- Frequent handwashing is crucial after contact with patients or lab specimens.
Handwashing Protocol
- Perform handwashing after patient and specimen contact.
- Wash hands with soap and water if visibly soiled or use alcohol-based handrub if not.
Personal Protective Equipment (PPE)
- Change contaminated lab coats immediately to avoid skin exposure.
- Use disposable aprons when splashing of blood or fluids is a risk, disposing of them in biohazard containers.
Surface Decontamination
- Clean and sanitize work surfaces at the beginning and end of shifts with a 1:10 bleach dilution or EPA-registered disinfectant.
- Disinfection targets the elimination of pathogenic microorganisms from surfaces.
Managing Spills
- Use facial barrier protection to prevent exposure when blood or fluids may splash.
- Masks should be worn if there's potential mucous membrane contact with blood or fluids.
Safety Practices in Waste Management
- Follow proper protocols for handling and disposing of laboratory waste to maintain safety and compliance.
