Recent chemical spills encourage review of laboratory practices.
On two different occasions, 2.5-liters were dropped and the glass bottle broke to release its contents. Glacial acetic acid and concentrated sulfuric acid were the hazardous materials involved in the incidents.
LEADERSHIP:
- Share this information with your lab personnel, be they Faculty, Staff or Students
- Ensure personnel have lab-specific safety training before working in the lab
- Create opportunities for continuous learning relating lab safety
- Use personal protective equipment including lab coats
- Create regular opportunities to discuss safety. Focus on solving problems rather than assigning blame
- Participate in and encourage open, ongoing dialog about safety
- Conduct hazard analysis prior to any experimental procedures
Guidelines for spill response planning:
- Spills in the laboratory can be prevented with good laboratory practices
- Know your limits. If you do not have the basic knowledge to confidently make the decisions required or if you have not been trained, request assistance from others
- Be prepared
- Learn about the hazards of the chemicals in your laboratory – Review safety data sheets
- Write Standard Operating Procedures (SOPs) to address hazards
- Have equipment and training necessary to follow the above SOP’s
- Prepare for spills with advance planning using the following spill prevention techniques:
|
Potential Cause of Spill |
Prevention Technique |
|
Container, such as a flask or beaker, tips over |
Secure containers and equipment to minimize the possible of tipping. |
|
Container dropping |
Keep containers and experimental equipment as low as possible. |
|
Breaking a container or a piece of experimental apparatus |
Protect containers from breakage by keeping other items from falling on them. |
|
A runaway reaction |
Plan experimental reactions to anticipate and to provide controls for undesired outcomes such as overheating. |
|
Releases during transfer of materials from one container to another |
Pay attention to what you are doing. Provide secondary containment in the event of spills. |
|
Holes and other leaks in transfer equipment such as pipes, hose, or valves |
Check for holes or leaks before use. |
|
Placing material in an incompatible container |
Check for compatible uses of chemicals, particularly solvents or aggressive solutions. Check the material and construction of containers and equipment with a goal of maintaining structural integrity. |
|
Breakage of thermometers or similar experimental equipment |
Select equipment that has reduced potential for breakage, e.g., replace mercury thermometers and electronic temperature devices. |
|
Breakage of container when dropped |
Purchase products in Safe-Cote™ or plastic-coated bottles so if they break, glass fragments and liquids are more likely to remain trapped. |

We encourage you to share the information with your colleagues. Use as many prevention measures as possible to keep our people, environment, and communities safe.
