Study Notes
Importance of Lab Safety
- Laboratory safety is essential to avoid accidents and ensure a safe working environment.
- Technicians and employees in the lab are responsible for adhering to lab rules and protocols to ensure their own safety and that of others.
Lab Safety Rules
- Absolutely no eating or drinking in the lab.
- Mobile phones and electronic devices are prohibited.
- Wash hands thoroughly with soap and water on entry and exit of the lab.
- Know the locations of emergency exits, eye wash stations, and showers.
- Always clean the lab bench before and after a lab session using 10% bleach solution or 70% isopropyl alcohol solution.
- Always wear personal protective equipment (PPE).
- Ask for help if unsure of anything.
Personal Protective Equipment (PPE)
- PPE is equipment that protects the user against health or safety risks at work.
- Lab coat: must be long-sleeved, knee-length, and made of drill cotton material.
- Shoes: must fully cover the feet.
- Long hair: must be tied.
- No dangling earrings.
- Gloves: must be worn.
- Safety masks and/or goggles: must be worn for appropriate testing.
Hazards in the Medical Laboratory
- Hazardous chemicals: corrosive to skin and eyes, and toxic.
- Electrical units: particularly hazardous when positioned close to liquids, should be fitted with ground-fault circuit interrupters.
- Biological hazards: bacteria, viruses, blood, tissue, and bodily fluids can carry diseases or hazardous allergens.
Material Safety Data Sheets (MSDS)
- A document that contains information on potential hazards (health, fire, reactivity, and environmental) and how to work safely with a chemical product.
- Essential starting point for a complete health and safety program.
- Contains information on use, storage, handling, and emergency procedures related to the hazards of the material.
- Prepared by the supplier or manufacturer of the material.
Learn essential laboratory safety rules and protocols to ensure a safe working environment and avoid accidents. Understand the importance of following lab rules and regulations.
