SafeWork SA has suspended three workers’ licences due to significant safety breaches involving powerlines. The incidents included mobile cranes and scaffolding being positioned too close to high voltage lines, posing severe risks.
In a recent spate of incidents involving powerlines, SafeWork SA has suspended the licences of three workers for up to twelve months due to safety breaches. These suspensions followed significant safety violations, highlighting the importance of strict adherence to safety protocols when working near powerlines. The incidents involved mobile cranes striking high voltage powerlines and scaffolding erected too close to live wires. With over eleven such occurrences reported this year, SafeWork SA has issued a warning to businesses and workers to maintain safe working distances and conduct thorough risk assessments.
Recent safety breaches and suspensions
SafeWork SA’s actions were prompted by a series of incidents. In one case, a mobile crane struck an 11kv powerline while installing rainwater tanks at Carey Gully. The crane operator and the rigger involved in this incident had their High Risk Work Licences suspended for six months. This incident underscored the necessity of maintaining a safe working distance of at least three metres, with a spotter on site to ensure compliance.
Another incident involved a scaffolder at Windsor Gardens, who erected a scaffold just one metre from an 11kv powerline and less than 30cm from a 415v low voltage line. This breach led to a twelve-month suspension of the worker’s licence. The mandated safe working distance in such scenarios is three metres, highlighting the severity of this violation.
The importance of adhering to safety protocols
These incidents are not isolated. SafeWork SA has reported eleven similar occurrences this year, including a recent incident at Largs North where a driver struck 11kv powerlines, causing a power outage. While no injuries were reported, the potential for serious consequences remains high.
SafeWork SA Executive Director Glenn Farrell highlighted the importance of compliance with work health and safety laws. He stated, “The inherent dangers of high risk work mean it is of critical importance that people comply with work health and safety laws. In suspending High Risk Work Licences, SafeWork SA is sending a clear signal we will not tolerate dangerous work practices. Working near powerlines can be fatal if correct procedures are not followed.”
Preventative measures and recommendations
To mitigate risks, SafeWork SA advises conducting thorough risk assessments before commencing any work near powerlines. Safe approach limits vary depending on the voltage of the powerline, the type of work being undertaken, and the equipment used. These distances range from one to six metres.
Key preventative measures include:
Turning off power: De-energising powerlines is the most effective way to eliminate the risk of electric shock. Discussions with South Australian Power Networks (SAPN) should be initiated promptly to arrange for power disconnection or re-routing.
Substitution and isolation: Where de-energising is not feasible, consider using non-conductive tools and erecting non-conductive barriers to prevent accidental contact with powerlines.
Visual indicators: Enhancing the visibility of hazards by using warning signs and SAPN-approved indicators like tiger tails on exposed conductors can significantly reduce risks.
Continued vigilance and education
The frequency of these incidents highlights the need for ongoing vigilance and education. Workers granted a High Risk Work Licence undergo specialist training and are expected to adhere strictly to safety protocols. Employers must ensure that all workers are continually educated on the latest safety measures and that workplaces are regularly inspected for potential hazards.
Working near powerlines requires the highest standards of safety and compliance. The recent licence suspensions by SafeWork SA highlight the dangers associated with high-risk work. By adhering to safety protocols, conducting thorough risk assessments, and implementing effective preventative measures, businesses can significantly reduce the risk of accidents and ensure a safer working environment.
