Types of safety hazards in the laboratory Common safety hazards include chemical hazards, biological hazards, physical
hazards, ergonomic hazards, electrical hazards, and fire hazards.
Components of the chain of infection The six components are: infectious agent, reservoir, portal of exit, mode of
transmission, portal of entry, and susceptible host.
Purpose of the Standard Precautions policy The purpose is to prevent the transmission of infectious agents in healthcare
settings by treating all blood and bodily fluids as potentially infectious.
Occupational Exposure to Blood-Borne Pathogens Employers must implement exposure control plans, provide training, ensure the
Compliance Directive requirements availability of PPE, and offer vaccinations against hepatitis B.
Types of personal protective equipment (PPE) PPE includes gloves, masks, goggles, lab coats, and face shields, used to protect
against exposure to hazardous materials.
Hand hygiene procedures according to CDC guidelines Hand hygiene involves washing hands with soap and water or using an alcohol-
based hand sanitizer, especially before and after patient contact.
Acceptable methods for handling biological waste Biological waste should be disposed of in biohazard bags or containers, while
sharp objects must be placed in puncture-resistant sharps containers.

Components of chemical hygiene plans Chemical hygiene plans include standard operating procedures, safety data sheets
(SDS), and training for handling hazardous chemicals.
Globally Harmonized System (GHS) GHS is an international system for classifying and labeling chemicals to ensure
consistent communication of hazards.
Standard hazard warning symbols Hazard warning symbols indicate the type of hazard associated with a chemical,
such as toxicity, flammability, or environmental risk.
National Fire Protection Association (NFPA) labeling The NFPA labeling system uses a color-coded diamond to indicate health,
system flammability, and reactivity hazards, rated from 0 (minimal) to 4 (severe).
Precautions for radioactive hazards Laboratory personnel should use shielding, limit exposure time, and maintain
distance from radioactive materials.
RACE actions for fire response RACE stands for Rescue anyone in danger, Activate the alarm, Contain the fire, and
Extinguish or evacuate.
PASS actions for fire extinguisher use PASS stands for Pull the pin, Aim the nozzle, Squeeze the handle, and Sweep from
side to side.

Role of quality management (QM) in the urinalysis QM ensures the accuracy and reliability of test results through standardization,
laboratory quality control, and continuous improvement processes.
Preanalytical errors Errors that occur before the analysis of a specimen, such as improper timing,
preservative use, exposure to light, or mislabeling.
Analytical errors Errors that occur during the analysis of a specimen, including interfering
substances, deteriorating reagents, or instrument malfunction.
Postanalytical errors Errors that occur after the analysis, often related to reporting results or interpreting
data.
Calibration checks Procedures performed to ensure that laboratory instruments provide accurate
measurements.
Quality control checks Tests performed to verify that laboratory processes and results are reliable and
accurate.
Equipment maintenance Regular procedures to ensure laboratory instruments function correctly and
provide accurate results.
