Application monitoring and auditing control system for remedial and supplemental
preservative treatment of wooden utility poles
1 Background
The main cause of premature failure of wood preservatives in wooden poles as a result of fungal decay
is inadequate impregnation, i.e.:


Sapwood has not been adequately penetrated with the wood preservative, and/or
Preservative retention has been insufficient.
Through the system of line pole inspections, poles with biological degradation are identified. Depending
on the extent of degradation, the poles are either supplementary and/or remedially treated with Boron
Rods, or the poles are removed from service and replaced with new poles.
2 Purpose
To ensure that the remedial / supplemental preservative treatment chemicals are applied in accordance
with the manufacturer’s instructions appearing on the packaging label, this application monitoring and
auditing control system has been developed and consists of all relevant quality control procedures and
documents.
3 Pack sizes
19
Boron Rods (14 mm diameter x 125 mm long) are packed in boxes of 100 rods per box and in cartons
containing 4 boxes, i.e. 400 rods per carton. Plastic plugs are also available in pack sizes of 200 or
1000 each.
4 Control procedure
4.1
The system is designed to record the particulars of poles requiring remedial and/or supplemental
treatment during the inspection phase. This is done on the POLE INSPECTION AND TREATMENT
RECORD. An example of a typical record sheet is attached. However, it is imperative that the record
provides for columns where the treatment details can be recorded.
4.2
The purchase and issue details of chemicals to inspectors are recorded by the company on the
attached BORON ROD RECEIPT AND ISSUE RECORD. Invoices / Delivery Notes are used to verify
purchased quantities. Information could also be verified with the supplier(s) of the chemicals.
A weekly/ monthly reconciliation between purchasing and usage is performed to determine usage and
accuracy of record keeping. The attached BORON ROD STOCK CONTROL RECORD is used to
perform this purpose.
