IS002 Solvent Vapors and a Confined Space Rescue

Episode Shownotes: Industrial Strength Podcast – Episode 2: Solvent Vapors and a Confined Space Rescue

Episode Overview:

In this gripping second episode of the Industrial Strength Podcast, hosts Randy, Steve, and Jeff delve into a real-life confined space rescue involving a methylene chloride solvent vapor incident. With their signature blend of technical insights and humor, the team walks listeners through the rescue operation, the chemical properties of methylene chloride, and the lessons learned from the call.

Segment Breakdown & Timestamps:

• [0:00 - 1:31] Introduction
• Randy, Steve, and Jeff return for another episode, introducing themselves and the topic: a solvent vapor incident resulting in a confined space rescue.
• [1:32 - 6:18] Incident Overview and Chemical Context
• An employee, attempting to address a solvent leak, was overcome by methylene chloride vapors in a confined pit area.
• Methylene chloride properties: a volatile organic compound with high vapor pressure and health risks, including anesthetic effects and oxygen displacement.
• [6:19 - 10:11] The Rescue Effort
• Two workers were overcome by vapors: the initial employee and a colleague who attempted a rescue.
• Industrial first responders executed a line-of-sight rescue for one worker, while the second regained consciousness and self-extricated.
• [10:12 - 14:00] Medical and Safety Challenges
• The team discusses the critical need for positive pressure breathing to expel methylene chloride vapors and restore oxygen levels.
• Medical interventions saved the unconscious worker, preventing a recovery situation.
• [14:01 - 17:54] Recon and Hazard Assessment
• HAZMAT team recon confirmed methylene chloride levels at 229 ppm in the pit area.
• Use of 4GAS meters and Draeger CMS provided detailed readings to ensure safety before ventilating the area.
• [17:55 - 22:31] Engineering Control Failures and Lessons
• Confined space signage and inoperable oxygen sensors failed to prevent the incident.
• Lack of a preventive maintenance program for portable oxygen alarms highlighted areas for improvement.
• [22:32 - 23:46] Recognition and Reflection
• Discussion on the lack of commendations for industrial responders despite life-saving efforts.
