CASE STUDY - 5 CHECK MATE
SITUATION: NET REPAIR INCIDENT: PANEL OF NET MISSING
RESPONSE: CHECK NETS PRIOR TO INSTALLING
The situation
‘You need to check it mate’ is a famil- iar instruction in all our working lives – whatever sector we work in. Sometimes people forget why we check, perhaps rush- ing the task or seeing no need. Here is a simple reminder of why we do it. Many fi sh farmers send their nets for inspection and repair to net service centres. These specialist centres give the opportunity for nets to be serviced and repaired under controlled conditions whilst leaving the farmers to get on with the farming.
On this occasion, this is exactly what happened. The farmer sent away a net for servicing and repair. On its return, the
net was redeployed and restocked. This was a routine service for the net centre and a rou- tine operation for the farmer.
The incident
Unfortunately, on this occasion, the serv- ice centre had made a mistake. And, the net was returned to the farmer with a panel of net missing. The net was deployed and stocked. And, unfortunately, fi sh escaped.
THE RESPONSE
The fish farming company now has a policy that all nets are checked prior to stocking using divers. The use of divers is expensive – but considered well worth it by the compa- ny concerned. And, they have extended this policy to check nets with divers after certain operations – such as grading. This helps to ensure that, should a fault occur with a net, that it is picked up in-time – whether it has resulted from their own activities or the omissions of others.
CASE STUDY - 6 IT’S A WRAP
SITUATION: FARM WEIGHTS INCIDENT: NET TEAR RESPONSE: DIVERS IDENTIFY PROBLEMS
The situation
Sometimes we’re lucky and a quick heave can free a situation. Sometimes we’re not and the same action can have the opposite result. Learning lessons and reducing risk is all about identifying possible scenarios and working to remove the ele- ment of luck in our responses. Although plastic circles have increased in popularity in Scottish fi sh farming, there remain many sites with steel pen units. This incident concerns a steel pen unit weighted using weights slung under the walkways to which the net is at- tached.
38 THE RESPONSE
The company had always been more than willing to use divers whenever necessary on-site to support their staff. Neverthe- less, it was thought that, in their keenness to resolve the situation themselves, staff overlooked the benefit that divers are more easily able to identify the true cause of a dif- ficulty and to help with its resolution. The company concerned have since made it a policy that, should a net be held fast, staff should not attempt to resolve this without the use of divers.

The farming staff became aware that a net had become stuck. In fact, the net had become wrapped around one of the ropes supporting the weight due to the strong tide. In trying to pull the net free, the staff inadvertently tore the net.
