Section 6633 - Attractive Nuisance Guards: Well-Pumping Units

(a) Where attractive nuisance guards are provided in addition to guards required by the Division, they shall conform to the following:

(b) The minimum vertical clearance through doorways, gateways, or passageways in attractive nuisance guards shall not be less than six feet six inches (6' 6"). A clear and unobstructed passageway through the doorways, gateways or other openings shall be as required in the General Industry Safety Orders, Sections 3224, 3225, and 3235.

(c) When only one (1) door, gate or other opening is provided in the attractive nuisance guards, as required in subsection (a)(1) of this section, a clear and unobstructed passageway of at least two feet (2') wide shall be provided and maintained between the attractive nuisance guards and the guards installed in accordance with the General Industry Safety Orders, Group 6, for moving parts of machinery.

(d) When a door, gate or passageway is provided in the well end of the attractive nuisance guard, in addition to the one required in the motor or engine end of the guard, and the space between the guards for the pitmans and cranks of pumping units and the attractive nuisance guards is railed, barricaded, or otherwise guarded to prevent its use as a passageway, the two-foot (2') clearance between these guards will not be required when provision is made for employees to perform lubricating duties on the pumping unit from a location outside the guards.

(e) When the access/egress openings through the attractive nuisance fencing guard are blocked at the well location, additional egress shall be provided away from the well head area.
