I've seen the difference firsthand.

In January 2025, an explosion ripped through PharmaCann's botanical extraction facility in Stevensville, Maryland. Two employees were injured, one severely. Four neighboring businesses were evacuated. Damages exceeded $250,000. The cause? A hydrocarbon extraction booth using propane and butane.

The emergency systems worked. Alarms, ventilation, sprinklers, all performed as designed. The facility was likely compliant on paper.

And people still got hurt.

I spent years building professional-grade closed loop hydrocarbon extraction systems. Here is what I know about the difference between a system that checks boxes and one that actually keeps people safe.

Be very careful who stamps your peer review.

There are a lot of shady engineers out there who will do anything for a buck. I have personally seen a peer review with absolutely no calculations. In a document that is supposed to calculate the pressure requirements for your system, that is terrifying. A stamp without the math behind it is worthless and it puts lives at risk. Use a reputable engineering firm, check their work, and ask questions if something looks thin.

C1D1 is the floor, not the ceiling. And your fan size matters more than you think.

We ran two 30-inch fans in our booths. That moves enough air to evacuate gas from the room almost instantly in an emergency. If you are running an 18-inch fan, you are looking at twice the evacuation time. In a gas emergency, that time is the difference between walking out and not walking out.

What is in the room matters too. Everyone uses bread racks to dry materials in the booth. The moment you throw a plastic cover over them you are creating a static electricity hazard. Dry air, moving plastic, and exposed gas is a combination that can ignite. Think through everything in that room, not just the equipment.

Sanitary clamps save lives. So do your nuts and bolts.

Change out your nuts and bolts every quarter. Not the clamps, just the nuts and bolts. It is a small, cheap habit that eliminates one of the most common failure points in a hydrocarbon system. Oregon OSHA has documented sanitary clamp failure as a leading cause of extraction explosions. Do not give it a chance.

If a line pops or a clamp blows, close your valves immediately.

I know it is scary. Everything in you wants to run. But if you can find a way to close the valves feeding the equipment you are containing the problem. The difference between closing those valves and leaving them open could be the difference between 10 pounds of gas in the room and 100 pounds. That is the difference between a bad day and a catastrophe.

SOPs are only as good as the people following them.

The best equipment in the world does not protect you from undertrained operators. If you are an investor putting money into an extraction operation, ask to see the training program. If they do not have one, that is your answer.

If you are buying equipment, funding a facility, or building one, do not just ask if it is compliant. Ask how it performs when something goes wrong.

That is the question that matters.
