In a busy laboratory, a chemical spill is often a question of when, not if. Whether it’s a knocked-over beaker of solvent or a fractured reagent bottle, gravity eventually wins.
However, the difference between a minor annoyance and a facility-evacuating disaster usually comes down to one thing: Preparation.
In the webinar "Dealing with Chemical Spills," Certified Industrial Hygienist Vince McLeod (Ascend Environmental) breaks down the critical steps labs must take before the glass breaks. With over 35 years of experience in industrial hygiene and environmental health, McLeod argues that effective spill response begins long before the liquid hits the floor.
Here are the core pillars of spill management covered in the presentation.
1. The "Pre-Spill" Reality Check
Most labs are reactive. They worry about spills only after they happen. McLeod emphasizes that a safe lab is a proactive one.
- The Inventory: You cannot clean up what you don’t know you have. An accurate, up-to-date chemical inventory is the foundation of safety.
- The SDS (Safety Data Sheet): In an emergency, you don't have time to Google. McLeod stresses the importance of having immediate access to the SDS for every chemical in your inventory to understand specific hazards like flammability, corrosivity, or toxicity.
2. The Myth of the "Universal" Spill Kit
Many labs buy a generic "Universal Spill Kit," shove it in a cupboard, and forget about it. This is a dangerous mistake.
- The Reality: There is no such thing as a truly universal kit. A kit designed for oil might be useless against an acid; a kit for water-based solutions might degrade when exposed to harsh solvents.
- The Fix: The webinar guides you through selecting the right spill control materials based on your specific chemical inventory. Do you need neutralizers for acids? Absorbents for flammables? The time to decide is now, not when fumes are rising.
3. The Response Framework: Alert, Assess, Contain
When a spill occurs, adrenaline spikes. To combat panic, McLeod outlines a clear, step-by-step response protocol:
- Alert: Notify others immediately. A silent cleanup attempt puts everyone at risk if fumes migrate.
- Assess: Is this a "simple" spill you can handle, or a "complex" spill requiring emergency services? Knowing your limits is vital.
- Contain: Stop the spread. Use barriers or socks to prevent the chemical from reaching drains or walkways.
4. Prevention is the Best Cleanup
The easiest spill to clean is the one that never happens.
- The Strategy: The presentation dives into "Safe Storage" principles—proper segregation of incompatibles, using secondary containment trays, and simple housekeeping. A clutter-free bench significantly reduces the "knock-over" risk.

Key Takeaway
As you watch, focus on the section regarding "Assessment." One of the most dangerous things a scientist can do is attempt to be a hero. McLeod explains exactly how to determine when a spill is too big, too toxic, or too dangerous for you to handle alone.
