The mix zone
PPE, silica, isocyanates, visitors, stop work. Same rules for a salesperson as for a finisher.
- Stay out of the wet edge unless you belong there
- Treat dew point, silica, and SDS as stop-work conditions
- Run a visitor like a hazardous operation, not a tour

Site-walk / visit protocol
- 01Before
PPE: boots, glasses, vest, hat. Confirm escort and orientation.
- 02Gate
Sign in. COI and badges are not optional at plants.
- 03On the floor
Stay out of the mix. Do not walk the wet edge for a photo.
- 04Photos
Permission. No faces of other trades without a reason. Lots and readings matter more than hero shots.
- 05After
Sign out. Notes in the job file the same day.
Hazards you must be literate in
| Word | What it means here |
|---|---|
| Silica | Grinding / shot-blasting concrete. Controls, not bravado. |
| Isocyanates | Some urethane / polyaspartic chemistries. Read the SDS. |
| HazCom | Labels, SDS, training. Current pack on site. |
| Dew point | Stop. Record. One client message. |
- Not this
The owner can walk wherever. It's their plant.
ThisWe still control the mix zone while we own the task.
- Not this
No SDS on the truck — we know this product.
ThisSDS pack on site. Always.
Takeaways
- You are a guest of a hazardous operation.
- Stop-work authority is real and it is yours.
- SDS belongs on site. Lot numbers get photographed as drums open.
