Extension cord repair among OSHA standard clarifications

OSHA in April released several standard letters of interpretation covering topics such as repairing extension cords, minimum distance between guardrails on industrial truck work platforms, and strength requirements for manhole covers.

In an April 12 letter, Bill Parsons, acting director of OSHA's Directorate of Construction, said employers can repair flexible No. 12 or larger extension cords. Repaired cords can be returned to use if they are in an "approved" state, according to an April 4 letter.

In another April 12 letter, Parsons said the distance between balusters within a guardrail system should not exceed 19 inches and employees should wear fall protection to be in compliance with 1926.451.
