Cytogenetics Lab Safety

Cytogenetics is the study of chromosomes, their normal and abnormal appearance and features and the role of chromosomal abnormalities in human disease. While cytogenetics is not an especially hazardous occupation, safety is still an important consideration in this as in all other branches of research.

Significance

• According to "The Principles of Clinical Cytogenetics," lab safety protocols in cytogenetics have improved markedly over the years. Today, lab inspections routinely check to ensure basic safety features are in place and operational. It's essential that labs provide their employees with appropriate safety equipment, not only to pass inspections but to minimize the chance of employee injury or accident as well.

Equipment

• All procedures that involve the use of flammable, toxic, carcinogenic or corrosive chemicals should be carried out under a fume hood with protective glass windows. Employees should wear goggles, gloves and protective clothing when working with these agents. The lab should have material safety data sheets (MSDS) available for all chemicals they use so that employees and management are aware of any possible hazards posed by specific compounds. The lab should also train all of its employees in their standard operating procedures and ensure these are followed at all times.

Infection

• One of the most important safety concerns in cytogenetics involves the specimens themselves; fresh patient samples may carry dangerous pathogens that could infect lab technicians if handled carelessly. Biological specimens should be stored in safety cabinets with appropriate features to prevent cross-contamination. Employees' exposure to samples should be minimized by wearing gloves and goggles and avoiding direct contact between samples and skin; procedures involving specimens should be performed under fume hoods to minimize the chance of accidental exposure to disease-causing agents.
