Study Notes
Personal Protective Equipment (PPE)
- The primary purpose of PPE in histology is to safeguard individuals from exposure to potentially harmful substances.
Hazardous Chemicals
- Formaldehyde is a common hazardous chemical found in histology laboratories.
Chemical Spills
- In the event of a chemical spill, immediate evacuation and alerting others is the top priority.
Specimen and Chemical Labeling
- Clearly labeling all specimens and chemicals in histology helps avoid accidental exposure and misuse.
Waste Disposal
- Used slides containing biological material should be disposed of in biohazard containers to prevent contamination.
COSHH
- All chemicals should be assessed under COSHH (Control of Substances Hazardous to Health).
Eating and Drinking in the Lab
- Eating and drinking are prohibited in all histology laboratories due to the potential for contamination.
Operating Lab Equipment
- Only trained personnel are authorized to operate advanced laboratory equipment such as microtomes and cryostats.
Hygiene
- Regular handwashing and disinfecting work areas are essential for reducing the risk of contamination and infection.
Handling Formalin
- Formalin should never be handled with bare hands, even in small amounts.
Proper Disposal of Biological Waste
- Proper disposal of biological waste in histology is crucial to prevent contamination, infection, and environmental hazards.
Essential PPE for Histology Lab Work
- Gloves are vital for protecting hands from exposure to chemicals and biological materials.
- Eye protection, such as goggles or safety glasses, is essential to safeguard against splashes that could cause eye damage.
Indicators of Hazardous Chemicals
- Labels clearly stating "flammable," "corrosive," or "toxic" are crucial indicators of potential hazards.
- Symbols such as skull-and-crossbones or exclamation marks are also warning signs of hazardous chemicals.
Importance of Health and Safety Training
- Health and safety training is paramount in histology laboratories to ensure personnel are equipped to handle hazardous materials and prevent accidents.
- Training can help mitigate risks such as chemical exposure, biohazard exposure, and equipment misuse.
