How Should Students Prepare to Use Chemicals in the Lab?


Working with chemicals in a laboratory setting requires careful preparation and adherence to safety protocols. Students who engage in science experiments and practical work in the lab must be well-prepared to handle chemicals safely to avoid any potential hazards. This article aims to provide a comprehensive guide for students on how to prepare themselves before using chemicals in the lab, as well as address some frequently asked questions regarding lab safety.

1. Familiarize Yourself with Chemicals:

Before using any chemicals in the lab, it is crucial to have a clear understanding of their properties, potential hazards, and safe handling procedures. Read the safety data sheets (SDS) for each chemical, which provide valuable information on toxicology, reactivity, and safe handling recommendations. Additionally, textbooks, manuals, and online resources can offer insights into the specific chemicals you will be working with.

2. Wear Appropriate Protective Equipment:

Personal Protective Equipment (PPE) is a vital component of lab safety. Students should always wear the necessary protective gear, including safety goggles, lab coats, gloves, and closed-toe shoes. These items provide a physical barrier between the student and any potential chemical hazards, reducing the risk of exposure or injury.

3. Understand Laboratory Protocols:

Each lab has its own set of protocols and guidelines that students must follow. Familiarize yourself with these rules before starting any experiments. Pay attention to safety signage, emergency equipment, and evacuation procedures. If you have any questions or are unsure about a specific protocol, consult your instructor or lab assistant.

4. Plan Ahead:

Before entering the lab, plan your experiment in detail. This includes understanding the purpose of the experiment, the chemicals required, and the steps involved. By having a well-organized plan, you can minimize the potential for accidents or mistakes.

5. Proper Handling and Storage of Chemicals:

When working with chemicals, it is essential to handle them with care. Always use the appropriate tools, such as pipettes or spatulas, to measure and transfer chemicals. Avoid direct contact with your skin or inhaling fumes by using the proper ventilation system. Additionally, ensure that all chemicals are stored correctly in designated areas, away from incompatible substances.

6. Cleanliness and Hygiene:

Maintaining a clean and organized workspace is crucial for lab safety. Keep your work area free from clutter to avoid accidental spills or mixing of chemicals. Clean up any spills immediately and dispose of waste properly. After completing your experiment, wash your hands thoroughly with soap and water to remove any chemical residue.

7. Emergency Preparedness:

Even with proper precautions, accidents can happen. Be aware of the location and proper usage of emergency equipment, such as fire extinguishers, eyewash stations, and safety showers. Familiarize yourself with the lab’s emergency procedures and have a clear understanding of whom to contact in case of an emergency.


Q: What should I do if I accidentally spill a chemical on my skin?
A: Immediately rinse the affected area with plenty of water for at least 15 minutes. Remove any contaminated clothing while rinsing and seek medical attention if necessary.

Q: Can I eat or drink in the lab?
A: No, eating, drinking, and smoking are strictly prohibited in the lab. Consuming anything in the lab increases the risk of accidental ingestion of chemicals.

Q: How should I dispose of chemical waste?
A: Follow the lab’s guidelines for disposing of chemical waste. Typically, chemicals need to be segregated, properly labeled, and placed in designated waste containers. Do not dispose of chemicals down the drain unless instructed to do so.

Q: What should I do if I inhale chemical fumes?
A: Move to a well-ventilated area immediately and inform your instructor or lab assistant. If you experience difficulty breathing or any other severe symptoms, seek medical attention promptly.


Working with chemicals in the lab requires adequate preparation and knowledge of safety protocols. Students should familiarize themselves with the properties and safe handling procedures of each chemical, wear appropriate protective equipment, follow lab protocols, plan ahead, handle and store chemicals properly, maintain cleanliness, and be prepared for emergencies. By adhering to these guidelines, students can ensure their safety and minimize the risks associated with working in a laboratory setting.
