At Henderson, safety isn’t just a policy—it’s a mindset. And for Ethan Welshon, an Underground Mine Production Operator II and four-year Henderson employee, that mindset led to a key discovery and new safety measures that will help protect his coworkers.
While recently filling in on the production crew, Ethan spotted steam rolling out from a draw point—something he had never seen before. Instead of brushing it off, his curiosity took over. After further investigation, he pulled out a few buckets of rock and immediately noticed they were unusually hot.

Ethan didn’t hesitate. He documented the anomaly with photos and videos and quickly escalated his concerns to Rick Sinclair, Senior Supervisor-Mine Development, and the engineering team. Their investigation revealed the heat likely was caused by a reaction with iron pyrite, a phenomenon previously observed at PT Freeport Indonesia. Engineers conducted further tests, including gas readings and temperature checks, ensuring the situation remained under control.

Ethan’s vigilance reinforced Henderson’s Stop Work Obligation—a critical policy that empowers employees to pause operations whenever something doesn’t seem right. Thanks to his actions, the company now has implemented new safety measures, including gas meters in the cabs of loaders operating in similar conditions. This proactive step will allow operators to monitor gas levels in real-time, enhancing safety in potentially hazardous areas.
"Ethan's story is a testament to the culture of safety and responsibility at Henderson," said Eric Wiese, General Manager-Henderson. "His quick thinking prevented a potential hazard and helped us strengthen our safety protocols. This proactive approach ensures we remain vigilant and prepared for future occurrences."
For Ethan, staying aware and speaking up wasn’t just the right thing to do – it was instinct.
"It may not be a big issue right now, but creating awareness of a potential problem could prevent something worse," Ethan said. "If something seems off, don’t be afraid to stop work and ask questions."
Ethan’s story serves as a powerful reminder: curiosity and attention to detail are key to a safe workplace. His ability to recognize something unusual, investigate it, and report it reinforces the company’s commitment to safety and continuous improvement.
"If you're not curious, you're being complacent," Ethan said. "And complacency is dangerous."
Through his actions, Ethan set an example for all employees—showing that safety starts with observation, questioning, and the courage to speak up.
