Product Overview

Summary: This SOP provides clear, practical guidance for managing electrical risks associated with drilling machinery in Australian workplaces. It sets out safe work methods, inspection requirements, and isolation controls to protect workers from electric shock, arc flash, fire, and equipment damage while ensuring compliance with WHS legislation.

Electrical systems on drilling machinery present a unique set of risks: high current draw, vibration, moisture, mobile plant movement, and often remote or harsh operating conditions. This Electrical Safety for Drilling Machinery SOP provides a structured, step-by-step framework for identifying, controlling, and monitoring electrical hazards across fixed, mobile, and portable drilling equipment. It covers pre-start inspections, cable and lead management, isolation and lockout/tagout (LOTO), safe connection to power supplies and generators, and response to electrical faults or incidents.

Developed for the Australian WHS environment, the procedure helps businesses demonstrate due diligence under WHS laws by embedding consistent safe work practices into daily operations. It reduces reliance on informal knowledge by clearly defining responsibilities for operators, supervisors, electricians, and maintenance staff. By implementing this SOP, organisations can significantly lower the risk of electric shock, arc flash, equipment fires, and unplanned downtime, while improving the reliability and lifespan of their drilling assets and providing clear evidence of compliance during audits, tenders, and regulator inspections.

Key Benefits

• Reduce the risk of electric shock, arc flash and electrical fires associated with drilling machinery.
