“The Importance of Proper Handling of Broken Glassware in Labs”


At our laboratory, we understand the importance of handling broken glassware with utmost care and responsibility. Broken glassware not only poses a risk to the people handling it, but it can also result in the contamination of samples & reagents, leading to inaccurate results and compromised experiments. In this blog post, we will discuss the importance of proper handling of broken glassware in labs and the steps that can be taken to ensure safe & effective handling.



Understanding the Risks of Broken Glassware

Broken glassware can cause serious injuries, from cuts and lacerations to exposure to hazardous materials. Moreover, the small fragments & shards of glass can easily become airborne, making it difficult to identify and clean up. In a laboratory setting, broken glassware can also contaminate samples & reagents, leading to inaccurate results and wasted time & resources.



Proper Handling of Broken Glassware

To ensure the secure and efficient handling of shattered glass in labs, the following actions should be taken:



  • Wear Proper Personal Protective Equipment (PPE)

Personal protection equipment (PPE) must constantly be utilised when handling broken glass. This consists of gloves, a lab coat, and safety goggles. The entire wrist & hand should be covered by cut-resistant gloves.



  • Contain and Clean Up the Broken Glassware

The area where the glassware was broken should be immediately cordoned off & marked as a hazard zone. The broken glass should be carefully collected using forceps or tongs & placed in a designated sharps container. Any loose fragments or shards should be swept with a broom and dustpan or picked up with sticky tape. The area should then be thoroughly cleaned with a wet paper towel or a vacuum cleaner equipped with a HEPA filter.



  • Dispose of the Broken Glassware Properly

Broken glassware should never be disposed of in regular trash. Instead, it should be placed in a designated sharps container that is puncture-resistant and leak-proof. The sharps container should be labeled as such & stored in a designated area that is inaccessible to unauthorized personnel.



  • Report the Incident

Any incident involving broken glassware should be immediately reported to the laboratory supervisor or safety officer. The incident should be documented, and any necessary follow-up actions should be taken, such as providing medical attention or conducting a risk assessment.




Proper handling of broken glassware is critical to ensure the safety of laboratory personnel and the accuracy of experiments. By following the steps outlined above, laboratories can minimize the risk of injury and contamination and promote a safe and healthy work environment.

Q: What type of personal protective equipment (PPE) should I wear when handling broken glassware?

A: Gloves, goggles, and closed-toe shoes are recommended to protect against cuts & eye injuries.



Q: What is the difference between regular waste and sharps waste?

A: Sharps waste includes any item that can puncture or cut the skin, such as broken glassware, and must be disposed of in designated sharps containers.

Q: How do I properly label sharps containers for broken glassware disposal?

A: Clearly label the container with the words “broken glass only” and follow any additional labelling requirements set by your lab.

Q: Can I dispose of broken glassware in the regular trash?

A: No, broken glassware must be disposed of in designated sharps containers to prevent injury to sanitation workers.

Q: What should I do if I get cut by broken glassware in the lab?

A: Clean the wound with soap & water, seek medical attention if needed, and report the incident to your supervisor.

Q: Can I reuse broken glassware after it has been repaired?

A: No, repaired glassware may be weakened and can break more easily, posing a safety risk.



Q: How can I prevent broken glassware in the lab?

A: Properly handle and store glassware, use caution when working with fragile items, and report any damaged glassware to your supervisor.

Q: What are some common causes of broken glassware in the lab?

A: Dropping glassware, using glassware that is too hot or cold, and improper storage or handling.

Q: What are some potential consequences of improper disposal of broken glassware?

A: Contamination of the environment, injury to sanitation workers, and fines for violating hazardous waste regulations.

Q: How can I dispose of broken glassware that has been contaminated with hazardous materials?

A: Follow your lab’s hazardous waste disposal protocols and consult with your supervisor or environmental health & safety staff for guidance.

Q: Can I recycle broken glassware?

A: Check along with your nearby recycling facility to see if they accept damaged glassware. If now not, do away with it in the sharps bins supplied.



Q: What should I do if I come across broken glassware outside of the lab?

A: Pick up the glass with care and put on gloves before throwing it away in an approved sharps container or contacting the relevant authorities for disposal.

Q: What should I do if I find broken glassware in the sink or drain?

A: Do not attempt to clean it yourself. For proper cleanup and disposal, speak with your supervisor or the environmental safety and health staff.

Q: Can I use glassware that has cracks or chips in it?

A: No, broken glass should be thrown away and replaced to avoid breakage and potential harm.

Q: What are some common types of glassware used in labs?

A: Glassware commonly used in laboratories includes Petri dishes, graduated cylinders, pipettes, beakers, and test tubes.
