4.15 - Rig Inspections and Maintenance cont.

An example checklist is included as Attachment 4.B - Drill/Direct Push Type Rig Inspection Checklist.

Maintenance

The drilling contractor should maintain logs, documenting all preventative maintenance performed on a

given rig. Any maintenance determined to be necessary once the rig has arrived on location should be

completed prior to drilling. Maintenance activities should never be performed while drilling. Specific items

to consider when performing maintenance include the following:

General

• Never use gasoline or other flammables to perform cleaning duties around the rig.

• Place all transmissions, gearboxes, hydraulic valves, and hoist levers in neutral before initiating repairs.

• Have all preventative maintenance, or other scheduled maintenance, completed as recommended.

• Shut down the drill rig and remove the positive cable from the battery to clean, repair or lubricate

fittings, unless the adjustment requires the rig to be running. The operator and lubricator must coordinate

their efforts to successfully perform the maintenance safely.

• While performing maintenance, either remove or tag the key to prevent accidental starting of the rig.

• Apply grease and oil only through oil and grease inlets.

• Always chock wheels, lower leveling jacks, and set hand brakes prior to working under a drill rig.

• Whenever possible, reduce operating systems to a zero energy state, that is, release all pressure from

hydraulic, drilling fluid and air pressure systems, prior to performing maintenance. Use extreme caution

when opening drain plugs, pressure caps, valves, and removing hoses and hydraulic lines.

• Never weld or cut on or near a fuel tank.

• Replace all caps, plugs, clamps, cables and guards prior to returning the rig to service.

• Never modify any part of the mast without permission from the equipment shop.

• If it should become necessary to drain oil, fuel, hydraulic fluid or any other industrial fluid in the field,

never allow the fluid to drain onto the ground. The fluid must be containerized and disposed of in an

appropriate manner according to site-specific requirements. Avoid spillage.

• All cab areas should be clean and free of loose materials, equipment, tools, and unsecured personal

items.

4.16 - Decontamination

Decontamination procedures are used to remove or neutralize contaminants that have accumulated on

personnel, samples, tools or equipment and to ensure the protection of personnel from permeating

substances, chemicals, and infectious agents. Decontamination reduces or eliminates transfer of these

contaminants to clean areas, prevents the mixing of incompatible substances, and minimizes the likelihood

of sample contamination. Various decontamination methods will physically remove, inactivate by chemical

detoxification, disinfection, sterilization, or remove contaminants by both physical and chemical means. In

many cases, gross contamination can be removed by physical means.
