Types of rigs used in Victoria. Land Rigs As the name implies, these rigs are primarily used on land. Also a few are capable of drilling holes to 10000m in depth Conventional Derrick Mobile Wheel or Track mounted Portable mast

Legal Requirements

• Employers and operators must, under the

Occupational Health and Safety Act 2004, ensure that plant is operated in a safe manner. The OHS (Plant) Regulations also detail the duties that employers must undertake before their employees operate this type of equipment.

• Employers must assess and control the risk of entanglement.

• Designers, manufacturers and suppliers must ensure that any drill rigs are safe and without risk to health when properly used.

• Public access restricted

Preventative control measures for tenement holders and drill rig operators

• ensuring the drill site layout reduces the need to handle, move or carry drill rod eliminating double handling of drill rods where practicable

• providing enough space for the driller’s offsider to easily

• move the hoisted drill rod away from the drill rig onto the work table, racks or frames

• ensuring drilling contractors provide minimum drill pad requirements for the drill rigs (these requirements are included in the work plan)

• ensuring the work plan and associated occupational health and safety systems include an examination of drill rig safety

• systems and devices prior to commencing the field program

• using a pre-start checklist that includes checking pull ropes, lifting equipment, break-out tools, guarding, walkways, adequate workplace and shelter

• reviewing all available drill rod handling and breaking systems for adoption onto their drill rigs as a positive means of hazard elimination. Where not practicable,

• implement a reduction of injuries to the drill crews

• completing a hazard identification at each drill site to ensure existing control measures are still effective

• providing fabricated non-slip walkways, steps and handrails where practicable

• providing a purpose-built drill shack or canopy to protect drill rig personnel from adverse weather conditions

• ensuring work systems are in place to prevent drill crews from working or standing directly beneath suspended or hoisted drill rods

• regularly checking and testing hoist limits on the pull rope

• regularly checking the sheave guard at the top of the mast to allow hoisting gear and drill rods to be raised and lower smoothly

• regularly examining rod break-out tools and associated equipment for wear and fatigue

• implementing quality checks by authorised service • providers, such as original equipment supplier or • manufacturer, to ensure maintenance and

modifications meet loading and quality standards • ensuring drill rig safety systems include thorough and

regular drill rig audits • rigs, in particular access and movement around the

drill site.

crushing units)

Common Issues- Non Compliance

• Poorly fitted or missing spin cages • Winch drum unguarded. • Fire protection equipment missing or not

maintained. • Work deck cluttered or slippery • Falls during access to and from ground from rig • Poor Tube pickup( Manual handling) • Lack of site security • Damaged mast structure

Surface Exploration Drilling Checklist

• The first part of the checklist focuses on the following four critical hazard areas commonly associated with surface exploration drilling:

1. Establishing drill site 2. Accessing drill site 3. Drilling operations 4. Drilling and ancillary equipment

• The second part of the checklist includes other OHS considerations.

Page 10

• Checklist developed by Worksafe, its available on our Website for industry to use and is used by Inspectors also

Note: This checklist should not be regarded as a comprehensive list of hazards – other hazards may exist which would need to be controlled so far as is reasonably practicable. See: http://www.worksafe.vic.gov.au/__data/assets/pdf_file/0005/14288/WorkSafe_Checklist_SurfaceExplorationDrilling_v4.pdf
