Introduction 

Exploration employees who work at drill sites face exposure to hazards associated with drill equipment and sampling processes as well as the inherent hazards of location, terrain and climate. In addition, it is common practice for the senior geologist at a project to be in effect the project manager, and thus wholly or partially responsible for health and safety of both exploration company employees and contractor employees. Exploration companies should select a capable drilling contractor with the correct drill equipment for the job – preferably a drill rig with automated or mechanized rod handling features to reduce the risks of injuries. Drills are required by law to have other safety features such as guards on all moving parts, emergency shut offs and lockout capability (not just unhooking the battery).

This section highlights common risks and hazards associated with drill sites and focuses on safe work procedures and strategies to prevent accidents. The aim is to highlight safety information for exploration geologists and geotechnical personnel etc., rather than for drillers and drilling contractors who should have their own safety programs and safe operating procedures (SOPs). All parties working at drill sites should be required to comply with all relevant regulations of the authorities having jurisdiction (AHJs).
