UMN Case Study
UMN Case Study
Likely causes (official cause unknown):
1. NaN3 + PEG 300 (moisture?) to yield hydrazoic acid
2. Overheating of NaN3colorless, volatile, toxic
and explosive liquid
Contributing factors:Moisture, contaminants in the reagents, stirring, scale
Explosive decomposition:
2 H2 + 3N2HN3
What Happened? – Direct Cause
What Happened? – Root Cause
Flawed Hazard Analysis:
Scale overwhelmed available controls Unequal mixing indication of safety issue Purity and choice of reagents
used new but not purified solvent substitution not vetted on large scale
What Happened? – Hazard Analysis
Risk of Hazard = severity x probability
Severity (scale, inherent properties material) Probability (experiment conditions)
Reaction conditions (T, P, atmosphere, light, solubility, purity of solvents and reagents, mixing, incompatibilities)
Operator conditions ( experience, attention, current health etc)

Identify how the incident could have been prevented Hazard Analysis Hazard Communication Safety Culture
Hazard Analysis- When, How?Scientific Method1. Theory
2. Prediction
3. Experiment
4. Observation
Plan Experiment
1. Propose Conditions
2. Identify Hazards
3. Hazard Analysis4. Select Controls
17
Evaluate Hazards1. Limits- Can I?
2. Best Practices- How do others?
3. Prepare for problems- What if?
1. Communicate Hazards
2. Standardize Process
3. Check plan and implementation
Document Safety Information
Limits ex. DOW SOC
Hazard Evaluation Resources

Controls reflect Hazard Analysis
Hierarchy of Controls Elimination: Remove the hazard
Eliminate the procedure Change your setup
Substitution: Replace the hazard Use a non-hazardous or less hazardous reagent Use a milder route or process
Controls reflect Hazard Analysis
Engineering: Change the process or equipment to reduce the hazard Fume hood Blast shield Steel vessel
Warning: Post signs warning of the danger Sign in your area with details and contact information External sign (room door, fridge door)
Controls reflect Hazard Analysis
Administrative: Establish policies to reduce risk or limit exposure Draft Standard Operating Procedures (SOPs) to detail
correct procedures
Personal Protective Equipment: Last line of defense (“seatbelt”) safety goggles/glasses lab coat gloves

Hazard Analysis Limits synthesis Add physical hazards Training
Hazard Communication Warning relevant journals & organizations Policy on group meetings SOPs SOCs
Safety Culture Spread Awareness
How can you apply lessons?
28
• PIs, Managers, Committees– set upper limits– Train on factors affecting probability & severity
• Experiment Planners– Design around primary reaction vessel– Discuss warning signs with researchers
• Experiment Performers– Follow group policies– Communicate with others, signage – Be Mindful
Life-Long Learning
Always search for new/more resources Literature updates New safety standards, literature and equipment New materials and techniques
Never assume you know all the answers Avoid being “overly comfortable” “That will never happen to me”
Communicate and Ask Questions Good Resources:
Advisor/PI Faculty Postdocs, lab techs, graduate students Safety professionals
Research Safety Officer DEHS
Don’t be satisfied with an unsafe method or conditions!

Questions
How did you hear about the incident? What was your initial reaction? Suggestions for identifying limits? How many people think SOCs are a good
idea? Going to review your group policies?
