Laboratory technicians, who specialize in the study of the microscopic structure of tissues, frequently work with various hazardous substances. These substances are used in tissue preparation, staining, and preservation processes and can pose significant health risks if proper safety protocols are not followed. Additionally to carcinogenic ethylene oxide which might be used for desinfection or decontamination, formaldehyde is primarily used for tissue fixation in histopathology which can cause irritation to the eyes, skin, and respiratory system.
Chronic exposure can lead to more serious health issues, including cancer. Some of chemicals used for dyeing, staining and fixating are carcinogenic or toxic if ingested, inhaled, or come into contact with the skin. Conducting a thorough risk assessments before starting any work to identify potential hazards is of utmost importance. To contain and ventilate hazardous vapors and fumes. a fume hood should be used and additionally adequate air exchange in laboratories is required.
Regular training on handling hazardous substances and proper handling and disposal of biological materials should be performed. Safe work practices include ensuring that all chemicals and samples are properly labeled with hazard information. Regular health check-ups to monitor for signs of exposure-related illnesses is additionally recommended.
By understanding and implementing these safety measures, laboratory technicians can mitigate the risks associated with exposure to hazardous substances in their work environment.
