Caught-In / Caught-Between

Caught-in/between hazards — one of OSHA's Fatal Four — crush workers between equipment and walls, inside unguarded machinery, and under collapsing material. These deaths share a pattern: someone entered a space a machine could close.

1
Respect pinch points

Between a swinging excavator and a wall. Between a backing truck and a dock. Between suspended steel and the column it's landing on. Identify the closing space before you stand in it.

2
Machine guards exist for limbs

Belts, gears, augers, PTO shafts, rotating shafts grab gloves, sleeves, and hair in a heartbeat. Guards stay on; loose clothing and dangling gear stay away; jewelry comes off.

3
Block and crib before you go under

Never work under equipment or loads supported ONLY by hydraulics — cylinders drift and hoses burst. Use rated jack stands, cribbing, or safety props.

4
Equipment swing radius

Barricade the counterweight swing area of excavators and cranes. Operators check mirrors and spotters before swinging — the guy taking measurements behind you can't hear the machine over his own task.
