(1)
Before initiating well servicing operations, the well shall be checked for
pressure and proper steps shall be taken to remove the pressure or to ensure
safe operation under pressure.
(2)
A treating or cementing discharge line shall not be placed under any mobile
equipment nor shall any mobile equipment be spotted over any such
line.
(3) A discharge pressure line
shall include sufficient flexible joints to avoid line rigidity and minimize
vibration at the wellhead.
