What Our Clients Have To Say
"100% would recommend Harlum for future high-risk or confined space
projects. Very professional team that was alert and knowledgeable in
their tasks and instrumental in ensuring safe and controlled access
and egress to confined spaces during the major planned outage."
“Excellent standards towards safety. The introduction of the confined space standby control room has improved monitoring and control of confined spaces and has freed up site operational resources to focus on the outage tasks and operating the running line. Friendly, professional workforce that genuinely cares about delivering a good service.”
