“PPE? Never heard of her.”
👀 When someone shows up at a high-voltage switchgear in sandals.
📹 The camera zooms in. We cry. Laugh. Repeat.
🧠 At ESC EU 2025, we’ll show you how to pick the right PPE – and not look like a space cadet (unless you want to).

“Eh, it didn’t really hurt.”

“what do you guys actually do?”
short answer: we prevent stuff from catching fire.
long answer: audits, consulting, labeling, arc flash, selective protection, and 200 cups of coffee ☕

We handle the ugly stuff: labeling, zoning, risk, you name it.
you just stay safe.

We love Excel.
but if you're using it to model your short circuit scenarios... maybe don’t.
we do actual fault & flow analysis so you can stop guessing and start fixing 💡

“It's low voltage – it's safe!”
No. No. NO.
Low voltage ≠ no hazard.
Batteries can explode. DC arcs can maim.
If it conducts, it can kill.

"Do you know the arc flash boundaries at your site?"
If the answer is “uhh...” — it’s time to review.
Arc flashes can reach 20,000°C and cause injury in milliseconds.
🚫 PPE isn’t optional
📏 Distance saves lives
💡 Knowledge is power

Can a good day outside the office improve how you work inside it?
