Gas Detection Units and Personal Alarm Monitoring Systems (PAMS)

Scope of this Contract/Procurement relates solely to the purchase of Gas Detection Units & Personal Alarm Monitoring System (PAMS)

Northern Gas Networks (NGN) has consistently deployed Teledyne Gas Measurement Instruments Ltd equipment for several years, with all operatives trained on this standardised kit. Maintaining a single, familiar equipment type is central to minimising user error and ensuring consistent operational safety. NGN's workshop depots provide minor in-house servicing, repair enabling efficient turnaround and continuity of operations. Replacement units are issued during servicing to avoid downtime, supporting uninterrupted field activity.

The main deliverable of this procurement is the continued supply of approved Gas Detection units and PAMS, with future purchases made on an ad-hoc basis to replace equipment that is beyond economic repair due to wear or damage. Retaining the existing supplier avoids the need for retraining, prevents inconsistencies between differing equipment types, and mitigates the increased risk of cable strikes associated with unfamiliar tools.

The purpose of this procurement is to maintain a reliable, standardised, and safety-focused equipment base across the full NGN geography, ensuring continuity of service, operational efficiency, and effective cable-strike prevention.
