SEACOR <br /> STANDARD SAFETY DRILLING SAFETY SSP 30 <br /> PROCEDURES <br /> • Use caution when traveling side-hill. Conservatively evaluate side-hill-capability <br /> of drill rigs, because the arbitrary addition of drilling tools may raise the center of <br /> mass. When possible, travel directly uphill or downhill. Increase tire pressures <br /> before traveling in hilly terrain (do not exceed rated tire pressure). <br /> • Do not attempt to cross obstacles such as small logs and small erosion channels or <br /> ditches at an angle. <br /> • Use the assistance of someone on the ground as a guide when lateral or overhead <br /> clearance is close. <br /> • After the drill has been moved to a new drilling site, set all brakes and/or locks. <br /> When grades are steep, block the wheels. <br /> • Never travel off-road with the mast/derrick of the drill rig in the raised or partially <br /> raised position. <br /> 1.4.30.21 Tires, Batteries and Fuel <br /> Discussion <br /> Tires on the drill rig must be checked daily for safety and during extended travel for loss <br /> of air, and they must be maintained and/or repaired in a safe manner. If tires are deflated <br /> to reduce ground pressure for movement on soft ground, the tires should be reinflated to <br /> normal pressures before movement on firm or hilly ground or on streets, roads and <br /> highways. Under-inflated tires are not as stable on firm ground as properly-inflated tires. <br /> Air pressures should be maintained for travel on streets, roads and highways according to <br /> the manufacturer's recommendations. During air pressure checks, inspect for <br /> Missing or loose wheel lugs. <br /> • Objects wedged between dual wheels or embedded in the tire casing. <br /> • Damage to or poorly fitting rims or rim flanges. <br /> • Abnormal or uneven wear and cuts, breaks or tears in the casing. <br /> The repair of truck and off-highway tires should only be made with required special tools <br /> and following the recommendations of a tire manufacturer's repair manual. <br /> • Batteries contain strong acid. Use extreme caution when servicing batteries <br /> • Service batteries in a ventilated area while wearing safety glasses <br /> corp-h&slssp-30 30-22 REVISED 11/02/92 <br />
