This subpart prescribes requirements relating to general working conditions on OCS facilities.

All staging, platforms, and other working surfaces and all ramps, stairways, and other walkways must be kept clear of portable tools, materials, and equipment not in use and be promptly cleared of substances which create a tripping or slipping hazard. When engaged in an activity on the drill floor in which the spillage of drilling fluid is inevitable, such as when pulling wet strings of drill pipe, footwear and flooring designed to reduce slipping substantially may be used instead of keeping the drill floor free of drilling fluid during the activity.

Openings in decks accessible to personnel must be covered, guarded, or otherwise made inaccessible when not in use. The manner of blockage shall prevent a person's foot or body from inadvertently passing through the opening.

(a) While repair or other work is being performed on equipment powered by an external source, that equipment must be locked out as required in paragraph (b) of this section or, if a lockout provision does not exist on the equipment, must be disconnected from the power source or otherwise deactivated, unless the nature of the work being performed necessitates that the power be connected or the equipment activated.

(b) If the equipment has a lockout or other device designed to prevent unintentional activation of the equipment, the lockout or other device must be engaged while the work is being performed on the equipment, unless the nature of the work being performed necessitates that the equipment be activated.

(c) A tag must be placed at the point where the equipment connects to a power source and at the location of the control panel activating the power, warning—

(1) That equipment is being worked on; and

(2) If the power source is disconnected or the equipment deactivated, that the power source must not be connected or the equipment activated.

(d) The tags must not be removed without the permission of either the person who placed the tags, that person's immediate supervisor, or their respective reliefs.
