Stored energy and lockout

Energy that is still in a system after it is shut off: electrical, hydraulic, pneumatic, spring, thermal, or gravity. In construction, 1926.417 covers lockout and tagging of electrical circuits, and 1926.702(j) covers concrete and masonry equipment.

Where it shows up

  • Raised dump beds, buckets, and forks
  • Charged hydraulic and air lines
  • Electrical panels and circuits being worked on
  • Concrete pumps and mixers during cleanout

Controls, most effective first

Work down the list. Rely on PPE only for the risk the controls above it cannot remove.
