Episode Overview

In this ninth episode of Industrial Strength Podcast, the team dives into a real-life hazmat response incident involving hot boxing—but not the kind you might be thinking of. This case study explores a hazardous situation involving di-tert-butyl-dicarbonate (also known as bauk anhydride) and how improper heating practices nearly led to a serious chemical incident.

The discussion covers the science behind drum bulging, thermal decomposition, and the dangers of improper temperature control in industrial settings. The hosts also share lessons learned from past incidents and how teams can prevent similar situations in the future.

Key Topics Covered

• Introduction to hot boxing and why this term has a different meaning in industrial hazmat response
• The incident: di-tert-butyl-dicarbonate drums placed in a warming room at excessive temperatures
• How improper heating led to pressurization and bulging of metal drums
• The chemistry behind di-tert-butyl-dicarbonate, its decomposition, and toxic inhalation risks
• Scene size-up and initial response actions taken by the hazmat team
• The use of thermal imaging cameras (TIC) to assess drum temperatures
• Proper PPE selection and mitigation strategies for relieving drum pressure
• The importance of engineering controls and how improper operator techniques contributed to the incident
• Discussion on a custom-built pressure relief device for safely venting plastic drums

Notable Moments and Key Takeaways

• Even low-pressure bulging in drums can indicate dangerous internal conditions
• Engineering controls and procedural adherence are critical to preventing hazardous situations
• The importance of scene size-up and using tools like TIC for better hazard assessment
• Why dual-role teams (such as entry and RIT) need careful consideration in hazmat responses
• The difference between metal and plastic drum pressure relief techniques
