Lab Safety Tips

Laboratory safety is essential for yielding reliable results and guaranteeing the protection of those employing the lab. Follow these guidelines for a cautious, productive experience each time.

Storage

• Storage shelves.

  Ensure that each substance in the lab has a label. This label tells what the substance is and includes any additional information pertinent to the substance. Make sure labels are never removed, damaged or impaired. If your lab has a stockroom, it should be well-lit, with adequate ventilation. Harmful substances should be separated from non-harmful substances, and anything that could leak should be placed in a second container made of material that can withstand the liquid. Instead of alphabetizing chemicals, store them by hazard class; alphabetizing can lead to substances that don't work well together sitting next to each on the shelf. Keep chemicals away from anything that generates heat, including windows on outer walls.

Personal Protection

• Wear safety goggles.

  Depending on the activity, wear safety goggles, chemical goggles or face shields. Tubes, pressurized instruments and other equipment can break, creating debris that can be harmful to your eyes. Ear muffs and ear plugs are encouraged to protect your ears from unsafe noise levels. Wear a lab coat, gloves and splash apron to protect against spills. Avoid open-toed shoes, loose hair, loose clothing and jewelry. Do not eat in the lab, and always wash your hands before leaving.

Record-Keeping

• Spreadsheet.

  Maintain current records of chemicals and equipment to help proper planning and emergency plan implementation. Document lab accidents in case a record is needed. Track when chemicals first come in and when they are opened. Also note expiration dates so resources are used economically.

Avoid Being Alone

• Crowds can be good.

  Work around others in the lab in case an emergency procedure needs to be performed. Make sure someone is aware if you are working alone.

Housekeeping

• Broom.

  Clean all lab surfaces of the lab, and remove unnecessary equipment. Handle spills according to label instructions, and keep walkways clear for safe movement and emergency exits. Store any chemicals that are not being used.

Chemical Safety

• Chemicals.

  Know spill procedures for all chemicals you are using. Never eat, smoke or drink around chemicals. Don't use broken or chipped glassware, and use the safety hood if you suspect harmful vapors.
