Supplies Required

  • Wood or Plexiglas strip—1/8″ x 1″
  • Wood or sheet metal screws—No. 10 x 1″

Mechanical Latches – Recommendation

Secure cabinet doors with mechanical latches.
Supplies Required

Mechanical Latches – Installation

  1. Provide mechanical latches on all doors. Test latches to assure that they can remain closed during severe shaking.
  2. Replace magnetic latches with mechanical latches.

Glass Containers – Recommendation

Wrap fragile bottles or dangerous materials with foam rubber or rubber bands to protect
Replace glass containers with unbreakable containers.

Bottle with Rubber or Foam “Bumpers”

Supplies Required

  • Foam rubber or rubber
  • Rubber bands


  • Store acids and other volatile chemicals separately and as close to the ground as possible.
  • Store heavy containers as close to the ground as possible.
