S SrEACOR .� STANDARD SAFETY DRILLING SAFETY SSP 30 PROCEDURES • Wise ropes must be properly matched with each sheave. If the rope is toa large, the sheave will pinch the wire rope. If the rope is too small, it will groove the sheave. Once the sheave is grooved, it will severely pinch and damage larger sized wire -rope. The following procedures and precautions must be understood and implemented for safe use of wire ropes and rigging hardware. • Use tool handling hoists only for vertical lifting of tools (except when angle hole drilling). Do not use tool handling hoists to pull on objects away from the drill rig; however, drills may be moved using the main hoist if the wire rope is spooled through proper sheaves according to the manufacturer's recommendations. • When stuck tools or similar loads cannot be raised with a hoist, disconnect the hoist Iine and connect the stuck tools directly to the feed mechanism of the drill. Do not use hydraulic leveling jacks for added pull to the hoist Iine or the feed mechanism of the drill. • When attempting to pull out a mired down vehicle or drill rig carrier, only use a - winch on the front_or_rear of_the—vehicle-and_stay as=far as-possible-away-=frnm=dhe wire rope.
