Harlum Services
Harlum provides fully managed support for confined space, outage and other high-risk site activity. Our team brings more than 15 years of COMAH and CDM experience, with clear roles, live communication and practical control from planning to close-out.
High-risk work depends on more than placing people on site. The work scope, entry controls, communications, monitoring, documentation and response arrangements need to function as one system. Harlum plans and manages that system around the site and the task.
Planning, team structure, control-room coordination, entry oversight, monitoring and reporting for multi-entry work.
Experienced site-based roles supplied and managed around the project requirement.
Live tracking of people, entries, radios, gas monitoring and communication.
Practical support for outages, high-risk work scopes and changing site priorities.
Oversees planning, deployment, client coordination and compliance across the work scope.
Manages daily activity, interfaces with client and contractor teams and keeps the delivery plan moving.
Tracks entries and personnel, manages communications and gas-monitor information and maintains visibility of the operation.
Control access, complete pre-entry checks, reinforce the safe system of work and support safe entry and egress.
Every element of the safe system of work is defined, recorded and owned — from pre-entry checks through to close-out documentation.
Harlum Services Principle
Lead with the site need, explain the response and finish with the operational benefit. The service should feel like an experienced project partner, not a generic labour supply.
A coordinated team and a clear picture of active work, people and interfaces.
Roles, responsibilities and handovers are agreed rather than left between contractors.
Site resources can remain focused on their core work while Harlum manages the specialist support function.
The team can adapt as work scopes, priorities and conditions change.
Project documentation supports review, assurance and close-out.
Planning, mobilisation, delivery and follow-through sit within one managed service.
The Harlum team has worked across COMAH and CDM sites, offshore wind, energy from waste, construction and major industrial projects. That background brings a practical understanding of work fronts, outage pressure, contractor interfaces and the importance of calm, consistent control.

“100% would recommend Harlum for future high-risk or confined space projects.”
SUEZ shift manager
Yes. Harlum can configure and manage the required operating, supervisory, control-room and attendant roles around the work scope.
No. Confined space management is a core capability, supported by wider site operations and skilled-personnel provision for high-risk projects.
Early involvement gives the project more time to review roles, interfaces, communications, equipment, documentation and mobilisation. Harlum can also respond to tactical requirements where the scope and timeline are clear.
