Cal. Code Regs. Tit. 8, § 1538 - Rock Drilling Operations

be performed by use of water or chemical solutions for controlling dust, or
other equivalent means.
(c) The
ends and each joint of air hoses 1 inch inside diameter or larger shall be
chained or secured, as necessary, to prevent whipping in the event of a
disconnected hose unless a suitable ball check device or equivalent is provided
at the air source.
(d) Air pipe
lines shall be protected against accidental impact from vehicles and falling
objects at points where breakage of lines would constitute a hazard to
employees.

(f) Tugger and anchor lines shall be provided
for securing drilling equipment on steep slopes.

required to use, personal fall protection as described in Article 24 for all
scaling and drilling operations performed on steep slopes. A positive descent
control device shall be used for all such applications.
