Tradebe Inutec - Tenant at Magnox Ltd Winfrith licensed nuclear site

Executive summary

Purpose of Intervention

Tradebe Inutec is a tenant on Winfrith licensed site, and operates a radioactive waste treatment facility. The purpose of this inspection was to obtain knowledge of Tradebe’s work activities and how it is managing key conventional health and safety risks.

The ONR CHS strategy has identified a number of priority conventional health and safety topics/activities to be covered during inspection activities.  These include asbestos, workplace transport and machinery safety.  These topics were examined during this inspction.

Interventions Carried Out by ONR

The key regulatory activities undertaken during the two day inspection were based around:

Explanation of Judgement if Safety System Not Judged to be Adequate


Key Findings, Inspector's Opinions and Reasons for Judgements Made

Site transport 

Tradebe Inutec has identified that site transport was one of their most significant conventional health and safety risks.  They have arrangements in place for managing traffic on site and there are plans to improve controls in some areas.  ONR expressed concern that not all areas were organised so that vehicles and pedestrians can circulate in a safe manner, as required by Regulation 17 of the Workplace (Health, Safety and Welfare) Regulations 1992, and control measures, particularly in relation to the offloading of containers, were not always implemented.  Tradebe agreed to review the risk assessment and current control measures against HSE guidance on workplace transport safety: HSG136.

Tradebe Inutec uses a number of battery powered forklift trucks.  The battery charging station is in close proximity to an electrical distribution board.  ONR requested they provide evidence of hydrogen testing or relocate the charging points away from this area to ensure compliance with DSEAR. 


Good standards of control were in place to prevent the spread as asbestos fibres during compaction.  However when employees enter the compacting chamber for cleaning, the current system of work does not reduce risks so far as is reasonably practicable in that the machine is not isolated from the power source.  Tradebe should devise a safe system of work that includes isolation from the power source.

Conclusion of Intervention

A number of examples of good standards were seen during the visit, but there were a number of areas for improvement which were summarised during feedback at the end of the visit.  ONR will write to Tradebe Inutec requiring action to be taken to address the issues identified and will follow up these matters at a subsequent visit to the site.
