Davit Arm Testing Requirements for UK Sites

A davit arm can look serviceable from ground level and still be non-compliant by default. The risk often sits in the details: an unverified base socket, a mismatched retrieval winch, missing locking components or a certificate that does not identify the asset it relates to. Davit arm testing requirements must be set by the equipment’s intended use, manufacturer instructions and the applicable legal framework, not by a generic annual visit.

For facilities and estates teams, the practical requirement is clear. Every davit system must be identifiable, compatible, examined at the correct interval and supported by records that prove its condition and safe operating limits. If those records are incomplete, an auditor cannot confirm compliance and a user cannot rely on the system.

Start with the davit arm’s actual use

A davit arm is not one fixed category of equipment. It may be installed as part of a roof-access system, used with a fall-arrest block, configured for rescue and recovery, or used to lift personnel or equipment into a shaft, tank or confined space. The testing regime changes with that use.

Where the arm forms part of a personal fall-protection system, its inspection should account for the arm, base, anchor interface, associated connecting device and rescue arrangement. Relevant product and system standards may include BS EN 795 for anchor devices and, where more than one user is permitted, CEN/TS 16415. The installation and periodic inspection approach must also reflect the manufacturer’s instructions and the system design.

Where the davit arm is used to lift people, the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) apply. This is not optional because the operation is occasional. A davit used for personnel lifting requires a thorough examination by a competent person at least every six months, unless there is a written examination scheme specifying a different interval. A davit used only to lift goods is generally subject to a 12-monthly thorough examination, again unless a written scheme applies.

Some installations have both fall-protection and lifting functions. In that case, treat the stricter requirements seriously. One annual fall-protection inspection does not automatically satisfy LOLER, and a LOLER report does not necessarily confirm that the fall-protection arrangement is fit for use. The scope must state exactly what was inspected and why.

What davit arm testing requirements should cover

A competent inspection is more than checking whether the arm rotates. It should establish whether the installed asset still matches its approved configuration and whether it can be used safely in the position where people will depend on it.

The engineer should first verify the asset identity. The davit arm, pedestal or socket, fall-arrest device, winch and any retrieval unit should have traceable identifiers. Serial numbers, safe working load markings and user limits must be legible and consistent with the manufacturer’s documentation. A missing asset tag is not a cosmetic issue. It breaks the audit trail and makes it harder to prove that the correct component has been examined.

The inspection should then consider the condition of the equipment and its installation. This commonly includes corrosion, distortion, cracks, unauthorised repairs, worn pins, damaged threads, loose or deteriorated fixings, condition of locking mechanisms and the engagement between the arm and its base. The surrounding structure matters as much as the arm itself. A sound davit cannot compensate for a corroded steel support, cracked concrete plinth or base socket that has been altered without design approval.

Operation must also be assessed. Depending on the model, this may involve checking rotation, boom positioning, locking positions, retaining pins, rollers, winch mounting points, cable condition and the operation of associated fall-arrest or retrieval equipment. Components must be compatible as a complete arrangement. Substituting a connector, winch or bracket because it appears to fit can invalidate the manufacturer’s approved configuration.

A good report distinguishes between observation, defect and immediate prohibition. A superficial coating issue may require planned remediation. A damaged locking pin, missing retaining device or compromised base connection may require the system to be removed from service at once. Pass/fail findings should be unambiguous.

Thorough examination is not the same as routine inspection

Dutyholders often use the words inspection, test and certification interchangeably. They are not interchangeable.

A pre-use check is completed by the user before deployment. It identifies obvious problems such as missing pins, damaged cable, unreadable markings or signs of impact. It does not replace a formal inspection.

A periodic inspection is a planned assessment of the fall-protection equipment and installation condition. For many roof-access davit systems, this is carried out at intervals specified by the manufacturer and risk assessment, commonly at least every 12 months. High-use, exposed, corrosive or safety-critical environments may justify more frequent checks.

A LOLER thorough examination is a statutory examination of lifting equipment by a competent person. Its purpose is to identify defects that are, or could become, dangerous. The resulting report must contain the prescribed information and be retained for the required period. If a defect presents an immediate danger, the competent person must report it to the relevant enforcing authority as well as the dutyholder.

A certificate is the output of a defined inspection or examination scope. It is not a blanket statement that every component on a roof is compliant. Procurement teams should ask what was included, which standards or instructions were used, the next due date and whether defects were closed out.

When is load testing required?

Proof load testing is often misunderstood. It is not automatically part of every periodic davit arm inspection, and applying an arbitrary load can create its own risk. Load testing should only be undertaken where the manufacturer requires it, following installation or relocation where the approved method calls for it, after significant repair or alteration, or where a competent engineer determines that it is necessary to verify the asset.

The test method, load, duration, equipment used and acceptance criteria must be controlled. That includes confirming the structural capacity of the supporting installation, not just the davit arm. A test applied to an unverified socket or support structure proves very little and could cause damage.

For existing systems with uncertain history, the correct first step is usually a technical review. Check original design information, installation records, component compatibility and visible condition. If those records are missing, the solution may involve structural verification, manufacturer consultation, non-destructive assessment or replacement. It depends on the system, its use and the evidence available.

The documentation your auditor expects to see

An audit-ready davit record should allow a competent reviewer to identify the system, understand its intended use and see what happened during the inspection. A vague certificate stating “davit arm tested” is not enough.

The documentation pack should include at least the following:

• Asset location, unique identification number, manufacturer, model and serial number.
• The davit arm’s approved function, user limit, safe working load and compatible equipment.
• Inspection or thorough-examination date, due date, scope and applicable requirements.
• Clear pass/fail status, defect descriptions and photographs where condition affects compliance.
• Actions required, priority, removal-from-service instruction where necessary and evidence of close-out.
• Engineer details, competence information and the signed certificate or LOLER report.

This level of traceability prevents a common failure across large estates: a certificate is filed, but nobody can prove which roof, socket or arm it covers. The result is missing paperwork at the point of audit and avoidable disruption when the equipment is needed.

Managing defects without losing control of access

A failed davit arm does not always mean the whole site must stop operating. It does mean the affected equipment must not be used until the risk has been assessed and controlled. The response should be proportionate and documented.

For example, an engineer may isolate one defective base socket while other independently certified systems remain available. If the davit is the sole rescue provision for a confined-space activity, the activity must not proceed until an approved alternative is in place. Do not allow a programme deadline to turn a known defect into an incident.

The most efficient approach is a single chain of accountability: inspection, clear defect report, fixed scope for remediation, installation work and updated certification. Sky Height Safety applies this process through the same specialist team, with photographic evidence and written reports issued within 48 hours. No subcontracted gaps in the chain and no uncertainty over what has been rectified.

Set the next due date before the engineer leaves

Davit arm compliance is controlled by preparation, not by a certificate chase before an audit. Keep an asset register, record the correct inspection and LOLER dates, check the system before each use and act on defects before they become access restrictions. When the arm, base, compatible equipment and paperwork all align, the system is ready for the moment someone has to rely on it.
