Direct answer: release by condition and evidence, not by the delivery date
For an African fibre project holding drums while rain delays construction, record where each drum is stored, how its ends are protected and what has happened since receipt. Before it moves to installation, have the responsible team complete the checks required by the cable instructions and project inspection plan. A previously accepted delivery is not proof that a drum remains ready after flooding, damage or an undocumented cut. Apply this guide to the actual local conditions; rainy seasons and storage risks differ across African regions.
Choose a storage position that remains usable after rain
The warehouse or site team should assess bearing capacity, drainage, access and the risk of rising water. Keep drums on suitable stable support in the orientation required by the supplier, with protection against unintended movement. Prysmian's general drum guide cautions against soft ground and flood-prone storage. Its product-specific details are not specifications for our cable. The site safety team must approve support and handling arrangements; this article is not a lifting plan.
Treat the cable ends as controlled protection
Confirm both ends remain sealed using the method specified for the supplied cable. A protective cover over the drum is not a replacement for an intact end seal. If an end is opened for inspection or a length is cut, record the operation and restore protection according to the approved instructions. Do not assume that an outdoor jacket or water-blocking construction makes an open end safe in standing water.
Separate exposure observations from a damage conclusion
Record whether there was ordinary rainfall, pooled water around the support, known immersion, a damaged seal or physical impact. Photograph the relevant drum ID and condition where safe. These observations do not all lead to the same decision. Move a questionable drum into a controlled hold status and ask the designated technical reviewer what assessment is needed; do not declare it sound just because the outside has dried or reject it solely because rain touched its packaging.
Keep an event record during a construction delay
For each drum, retain its receiving record, storage position, inspection dates, movements, cuts, resealing and any incidents. Assign a person to inspect after events that may change the condition, such as flooding or nearby equipment impact, in addition to the project's routine interval. If crews share a depot, use a clear released/held status so a different team does not load a drum before the issue is resolved.
Review before handing the drum to the installer
Check legible identity, drum integrity, visible cable condition and the protective state of the ends against the approved procedure. Verify that the length and construction still match the work package, particularly after partial use. Required optical checks and any additional testing should be specified by qualified personnel under the acceptance plan. A factory report remains useful historical evidence, but it does not assess an incident that occurred later in the site yard.
Do not use an optical pass to dismiss a separate concern
If a drum has a damaged flange, unsafe support or a suspected sheath or sealing problem, record that issue separately. A satisfactory optical result does not itself authorize unsafe handling or resolve every mechanical and environmental concern. The reviewer should decide whether the drum can be released, needs an approved corrective action or must remain held, with the decision attached to its ID.
Prepare supply around the storage constraint
Tell the supply team the intended holding period, local receiving conditions, available unloading equipment and installation sequence before confirming delivery arrangements. Ask for the supplied construction's handling and end-protection instructions and agree the inspection evidence. Factory packing photographs describe the dispatch condition, not a guarantee of unlimited outdoor storage. The cover image shows factory drums, not a local rainy-season installation.
FAQ: Does a wet wooden drum mean the cable has failed?
Not by itself. Record what was exposed and inspect under the applicable procedure. Drum condition, end protection, possible immersion and cable condition require separate consideration.
FAQ: Can we just replace a missing end cap and release the drum?
Do not treat resealing as proof that no ingress occurred. Record the exposure and obtain a technical decision about assessment and release before use.
FAQ: How long can drums remain outdoors?
Use the supplier's instructions for the actual cable, drum and protection system, together with the site's conditions. This guide gives no universal storage period or warranty extension.
Storage-to-installation decision record
| Check | Evidence | Action if unresolved |
|---|---|---|
| Location and support | Current drainage, support and safe access assessment | Have the site team arrange approved protection or relocation |
| End protection | Seal condition and any opening or resealing record | Hold and request exposure assessment |
| Identity and quantity | Drum ID, construction, cuts and remaining length | Reconcile against the assigned installation section |
| Incident and acceptance | Observations, required checks and named reviewer | Do not release until the decision is documented |
Before releasing stored drums
- Confirm identity and the applicable supplier instructions.
- Assess current drainage, support and handling access.
- Check both ends and record any exposure or resealing.
- Review movements, cuts and weather or impact incidents.
- Complete the checks specified by the qualified reviewer.
- Record release status and pass the evidence to the installer.
