Before anyone steps inside a confined space, the most Important work has already happened, or it hasn't.
I've been in safety long enough to know that the most dangerous moment in a confined space operation isn't when something goes wrong inside. It's in the hours before — when people assume they're prepared and they're not. When the permit gets signed without a real conversation. When the rescue plan is a document nobody has read and nobody has practiced. That's where incidents are born.
We are not hoping for a good outcome. We are engineering one. And that engineering happens at the planning table, not at the entry point.
Goal Zero Starts Before You Open The Hatch
At MIG, Goal Zero means zero incidents, zero accidents, zero environmental releases, not as a target, but as the standard. In confined space work, that standard demands you treat the planning phase with the same seriousness you'd bring to the rescue itself. If your rescue plan only activates when something has already gone wrong, you've already lost time you may not have.
Know Where Everyone is, and What's Around Them
Before any entry, I want to know exactly where every person will be and every hazard that could reach them. Atmospheric conditions inside a confined space can shift based on what's happening elsewhere in your facility. Yesterday's test result tells you about yesterday. That's why monitoring is continuous throughout the entry, not a one-time check before you go in. Engulfment risks, space geometry, energy isolation, they all need to be mapped before the first person steps inside.

Build The Plan for This Space, Not Every Space
The most common mistake I see is the generic template, someone pulls up a plan from a previous job, changes the date, and considers it done. That will get someone hurt. Every permit-required confined space has its own character. The hazards, geometry, and access points are different every time. Your plan has to reflect that. And the permit documents that planning has happened, it does not replace it.
The permit documents that planning has happened. It does not replace the planning.
Communicate it, To Everyone
You can have the best rescue plan ever written and it will fail if the people involved haven't walked through it together. The pre-entry briefing is where the plan becomes real. Every entrant should be able to answer without hesitating: What are the hazards here? What signs tell me it's time to get out? How do I reach my attendant? If someone pauses, you stop and work through it before anyone goes in.
And communication doesn't stop at the entry team. Adjacent crews, contractors, nearby supervisors, they need to know an entry is happening, who the attendant is, and what a rescue activation looks like. In a rescue situation, an uninformed bystander isn't just unhelpful, they're a hazard.
What Goal Zero Actually Demands
Goal Zero means we don't accept a confined space fatality as something we just hope doesn't happen. We believe, and act on the belief, that with the right plan and the right communication, we can prevent it every time. That belief makes the hazard assessment non-negotiable. It makes the pre-entry briefing non-negotiable. And it means when we find a gap, we close it before the entry happens, not after.
