Important Lab Safety Rules
When working with solutions in the laboratory, it is crucial to follow specific safety standards.
Here are five important rules that should always be observed:
- Always wear appropriate personal protective equipment (PPE), such as safety goggles, gloves, and lab coats, to protect from any spills or splashes.
- Never eat or drink in the laboratory to avoid contamination and accidental ingestion of chemicals. Laboratory glassware should not be used for eating or drinking.
- Handle all chemicals with care. Make sure you understand the hazards by checking the safety data sheets (SDS) before use. Follow the correct procedures for measuring, mixing, and disposing of chemicals.
- Be cautious with heat sources. Turn off Bunsen burners and other heating devices when not in use and always keep flammable materials at a safe distance.
- In case of an incident, such as a chemical spill, immediately inform your teacher or laboratory supervisor. Know the location of safety equipment like eye wash stations and fire extinguishers.
Moreover, remember to never add water to acid, always acid to water, and understand that some glassware like measuring cylinders should not be heated due to the risk of breaking.
Following these rules will ensure a safe and productive experience in the laboratory for everyone involved.
