Laboratory work is an essential part of college and university science programs, providing hands-on experience in conducting experiments and handling scientific equipment. However, working in a lab also comes with inherent risks. To ensure a safe and productive environment, students must adhere to essential lab safety rules and best practices. This guide outlines fundamental safety precautions every student should follow.

1. Avoid Working Alone in the Lab

Working alone in a laboratory is not considered a safe practice. Students should always work when others are present to ensure that immediate assistance is available in case of an emergency.

Lab Safety Management Certificate

The Lab Safety Management certificate is more than training—it’s a professional advantage.

Gain critical skills and IACET-approved CEUs that make a measurable difference.

Best Practices:

  • Always work when others are present.
  • Inform a supervisor or colleague about your location.
  • Arrange periodic check-ins with lab partners.
  • Ensure emergency contact information is readily available.

If working alone is unavoidable, notify a supervisor or a colleague about your location and have periodic check-ins with others in the vicinity to enhance safety.

2. Use Proper Eye Protection

Eye protection is critical in any laboratory setting where chemicals, pressurized containers, electrical wiring, or mechanical equipment are in use.

Eye Protection Guidelines:

  • Wear safety glasses for general lab work.
  • Use chemical goggles when handling hazardous substances.
  • Wear face shields when dealing with high-risk equipment.
  • Always check Safety Data Sheets (SDS) for specific requirements.

Safety glasses should be worn for general lab work, while chemical goggles or face shields are necessary when handling hazardous chemicals or operating high-risk equipment. The appropriate eye protection can be found on the  Safety Data Sheets (SDS) associated with each chemical.

3. Protect Your Hearing with Proper Ear Protection

Exposure to loud noises in the lab can cause temporary or permanent hearing loss. Noise levels below 80 dB are generally safe, but anything above 130 dB can be hazardous.

Hearing Protection Tips:

  • Use earplugs for noise levels between 80-95 dB.
  • Wear earmuffs for noise levels above 95 dB.
  • Report suspected noise hazards to your supervisor.
  • Limit exposure to loud environments whenever possible.

Earplugs are recommended for noise levels between 80-95 dB, while earmuffs offer better protection for higher noise levels. If you suspect that noise levels in your lab may be harmful, inform your supervisor so that a sound level assessment can be conducted.

4. Use Respiratory Protection When Necessary

Respiratory protection should only be used if recommended by a safety coordinator.

Respiratory Safety Measures:

  • Only use respirators approved by your safety coordinator.
  • Ensure a proper fit for effectiveness.
  • Select the correct cartridge for specific applications.
  • Get trained and fitted by certified personnel.

Proper respirator selection and fit are essential to ensure effectiveness. Various types of respirators and cartridges are available, each designed for specific applications. If respiratory protection is required, ensure that you receive proper training and fitting from a certified safety professional.

5. Wear Appropriate Lab Clothing

Protective clothing is essential to prevent exposure to hazardous substances.

Clothing Safety Tips:

  • Always wear lab coats to protect against spills.
  • Use additional protection like gloves and aprons for corrosive chemicals.
  • Avoid loose clothing, open-toed shoes, and dangling jewelry.
  • Tie back long hair to prevent entanglement.

Lab coats should be worn in situations where splashing or spills may occur. Additional protective gear, such as gloves, splash aprons, goggles, and face shields, should be used when working with corrosive or hazardous chemicals. Open-toed shoes and sandals should never be worn in the lab. Additionally, loose hair, clothing, and dangling jewelry should be secured to prevent accidents.

6. Choose the Right Gloves for the Task

Hand protection is necessary for handling hazardous materials. However, not all gloves provide the same level of protection. Always use gloves made from materials suited to the chemicals or substances you are working with.

Glove Selection Guide:

  • Match glove material to the chemical being handled.
  • Check Safety Data Sheets (SDS) for recommended gloves.
  • Dispose of gloves properly after hazardous exposure.
  • Inspect gloves for damage before use.

The SDS for each chemical specifies the appropriate glove type. Improper glove selection can lead to chemical exposure or inadequate protection.

7. Do Not Eat or Drink in the Laboratory

Food and beverages should never be consumed in a lab where chemicals are stored or used. Contamination risks can lead to accidental ingestion of harmful substances.

Food Safety Guidelines:

  • Never consume food or beverages in the lab.
  • Store food outside laboratory areas to prevent contamination.
  • Wash hands thoroughly before leaving the lab.
  • Follow institutional policies on lab hygiene.

Additionally, students should always wash their hands and arms thoroughly before leaving the lab to prevent exposure to hazardous chemicals outside the controlled environment.

Frequently Asked Questions (FAQs)

1. Why is it important not to work alone in a lab?

Working alone increases the risk of delayed emergency response in case of an accident. Having colleagues nearby ensures that help is readily available if needed.

2. What type of eye protection should I use in the lab?

Safety glasses are suitable for general lab work, but chemical goggles or face shields should be used when handling hazardous chemicals or operating equipment that poses a risk of splashes or debris.

3. How can I determine the right gloves for handling chemicals?

The appropriate glove type is specified in the Safety Data Sheets (SDS) for each chemical. Always check the MSDS before selecting gloves to ensure adequate protection.

4. Why is eating and drinking prohibited in the lab?

Food and beverages can become contaminated with hazardous chemicals, leading to accidental ingestion. To ensure safety, never consume food or drinks in the lab.

5. What should I do if I suspect a noise hazard in the lab?

If you believe that noise levels may be harmful, notify your supervisor. A sound level assessment can be conducted to determine if ear protection is necessary.

Final Thoughts

Following general lab safety rules and best practices is crucial for college and university students to prevent accidents and ensure a secure learning environment. By adhering to proper protective measures, using the right equipment, and maintaining awareness of potential hazards, students can safely conduct experiments and research without unnecessary risks.
