Hot work habitat, pressurized enclosure film

What it is

A pressurized hot work habitat: the sealed room a crew builds around a job so a spark can never meet gas. In 74 seconds the panels go up around a live pipe, blowers push fresh air in low and pull it out high, the room holds above outside pressure, the weld starts, and when methane reaches the high detector the shutdown cuts power to the weld and closes the air intake.

It is a concept I built on my own to show how a film explains a safety system that a photo can't. Sizes are approximate, and the pressure readout is illustrative.

How it was made

• ModelWall panels, frame, the seal around the pipe, blowers, ducts, two gas detectors and the shutdown panel, each its own object so it can move on its own.
• MotionThe panels arrive and lock seam by seam. Air is drawn as moving particles, in low and out high. Gas rises toward the high detector until the shutdown trips.
• LabelsTen callouts, each tied to its part's position in every frame, so the label stays on the part while the camera moves.
• Render1,788 frames in Blender EEVEE at 24 frames a second.
• SoundScore and sound effects written in code. No samples, no voice; the words are on screen.
