Sarnia Firm Fined $90,000 After Hydrogen Explosion Injured Three Workers
According to the Daily Commercial News, AlumaPower Corporation of Sarnia, Ontario was fined $90,000 on April 20, 2026, after a workplace explosion injured three workers during testing of an experimental aluminum-air galvanic generator in November 2023. Investigators found hydrogen gas accumulated inside an enclosed fume hood when ventilation failed, eventually igniting. Ontario’s Ministry of Labour found the testing was conducted in a space not designed or rated for processes capable of producing explosive gases, and that multiple ignition sources were present. All three workers recovered and returned to work.
What It Means for Subcontractors
- Experimental or prototype testing environments carry elevated hazard classifications. If you’re working in or around R&D facilities, verify that the work area is rated for the specific chemical and explosion hazards involved before your crew steps on site.
- Ventilation failure is a leading cause of gas buildup incidents. Subcontractors handling any work near processes that produce flammable gases should confirm that safety systems are actively functioning, not just installed.
- A guilty plea resulted in a $90,000 fine, but the liability exposure for on-site subcontractors in similar incidents can extend well beyond fines to civil claims and lost contracts.
