Safety rules in chemistry laboratory
Welcome to the world of chemistry! It is a subject where you will explore the fascinating world of elements, compounds, reactions, and much more. However, it is important to remember that working in a chemistry lab can be dangerous if safety rules are not followed. In this guide, we will discuss important safety rules that you should follow when you are in a chemistry lab.
What to wear to the chemistry lab?
The type of clothing you wear to the laboratory is very important for safety reasons. Here are some guidelines:
- Wear safety glasses: Protect your eyes from harmful chemicals and possible splashes.
- Lab coat: Wearing a lab coat will protect your skin and clothes from spills.
- Closed shoes: Always wear shoes that completely cover your feet to protect them from falling objects or spilled materials.
- Gloves: Use gloves to protect your hands when handling hazardous chemicals.
- Tie long hair back: This prevents hair from catching fire or getting caught in appliances.
Laboratory environment
The chemistry lab is a place for serious study. Here's how to maintain a safe environment:
- Keep it clean: Always keep your workspace clean before, during, and after experiments to avoid contamination and hazards.
- Do not eat or drink: Never take food or drink into the lab, as the chemicals may contaminate them.
- Organize tools: Keep all tools properly organized to avoid accidents.
- Know the exit routes: Familiarize yourself with the location of exit routes and safety equipment such as fire extinguishers.
Management of chemicals
When you work with chemicals, you must be very careful. Chemicals can be dangerous, so remember:
- Read labels carefully: Always read labels carefully before using chemicals to understand their properties and hazards.
- Use the proper container: Only use containers made for specific chemicals. Never reuse old containers for different chemicals.
- Don't taste: Never taste chemicals or any substances found in the laboratory.
- Keep ventilated: Some experiments need to be conducted under a fume hood to avoid toxic fumes.
Conduct during experiments
It is very important to act responsibly during experiments to avoid accidents. Here are some tips:
- Follow instructions: Always follow the directions from the teacher or instruction manual.
- Be careful of flames: Keep flammable materials away from open flames.
- Never work alone: Always have someone else with you in the lab.
- Handle glassware with care: Glassware can break easily. Be sure to handle all glass equipment with care.
Handling emergencies
Even if you're careful, accidents can happen. Be prepared by knowing what to do in an emergency:
- Report accidents: Notify the teacher immediately about any accidents, no matter how small.
- Use safety equipment: Learn how to use safety showers, eye wash stations, and fire extinguishers.
- Know emergency procedures: Familiarize yourself with the lab's emergency procedures, including evacuation routes.
Special safety signs and symbols
In the lab you will see special signs and symbols. Here is what some of them mean:
- Flammable: This symbol indicates material that can easily catch fire. Handle with care.
- Toxic: This is an indication of substances that are poisonous. Avoid contact and inhalation.
- Corrosive: Indicates substances that can burn skin and destroy clothing. Wear protective gear.
- Explosive: Products marked with this symbol may explode. Handle with extreme care.
Conclusion
Safety in the chemistry lab is important to ensure a successful and enjoyable learning experience. By following these safety rules and being mindful of your actions, you can help create a safe environment for everyone. Remember, safety is everyone's responsibility. Always think before you act and when in doubt, ask your teacher or supervisor.
