“The whole building shook and there was just a massive bang close enough that I thought it was our building,” Lowenberg said.
“I ran outside to take a quick look and it wasn’t so I ran back in and called 911.”
When she returned outside, Lowenberg said she could see flames and smoke – early reports indicate the explosions happened in southeast Estevan at about 10 a.m.
“It was a panic for sure. Other companies in the area was calling to see if it was us,” Lowenberg said.
Connor Barnstable was working at Performance Machining when the explosions happened. Barnstable said they took place about 180 metres away, near Regens Metals.
“Me and another employee were just working and our one manager said he seen some smoke and flames coming over the Regens’ disposal yard,” Barnstable said.
“We stopped what we were doing, we heard another little explosion and went outside… I started videotaping and you could the smoke and flames getting bigger and bigger.”
Once outside, Barnstable heard another large explosion and said it could be felt throughout their entire workshop.
“There was a bunch of things in our building coming off the walls from the explosion,” Barnstable said.
“We could physically feel it on our bodies, a big blast of air. It was pretty wild.”
A spokesperson with the Saskatchewan RCMP says Occupational Health and Safety is now leading the investigation into the explosion.
Global News has reached out to Regens Metal for more information on Monday’s events and is still waiting to hear back.
