Our campus has experienced several chemical spills in the past linked to piranha solution reactions. When powerful oxidizing mixtures or other gassy waste materials are sealed in containers, they can build up significant pressure. This pressure can cause containers to rupture, leading to dangerous spills and unnecessary hazards. Venting caps provide a simple, effective safeguard by allowing pressure to escape in a controlled manner, helping protect both researchers and facilities. 

Using these caps is a proactive step toward protecting our people, equipment, and research. This simple addition helps you maintain a secure lab environment and stay in compliance with safety regulations.  

Laboratories can request venting caps directly through the EHS Assistant Waste Supply Request tool. This convenient option ensures labs can quickly obtain the supplies they need to maintain safe storage practices. 

To request venting caps or learn more about their use, please contact EHS at labsafety@missouri.edu. Together, we can reduce risks and continue building a safer research environment at Mizzou.
