Initial Email Detail:

I would appreciate it if you could forward the following query to members to see if any of them have practical suggestions that we can use for the following.

When operators and maintenance personnel are working on site at our Bulk Solvent Tanker Farm they frequently need to mount and dismount the rear section of Bulk Solvent Road Tankers in order to connect/disconnect hoses, fit connection pieces etc and operate the tanker hand valves. This working area on the rear section of the road tanker trailers can have a multitude of configurations but is typically about 3.5 – 4 foot square and about 3.5 – 4 foot off the ground. Some trailers have access steps built into them and others do not.

Recently we had an accident on site where an operator who was working on the rear of the road tanker lost his balance and fell backwards onto the road behind him landing on his back, injuring himself significantly in the process. This is the first accident or incident of this kind that we have experienced in completing this task which has been ongoing daily for nearly thirty years. We have reached out to sister companies, competitors and regulators to see if anyone else has implemented Engineering Controls in this area to help alleviate this risk and prevent a reoccurrence but to date we have not received anything useful so we would appreciate any advice or suggestions that your members can offer. Due to the relatively low height this task does not lend itself to conventional fall arrest systems on site.

Thank you,

In reply to your Joiff request:: 
While I dont have a solution to minimise the risk of the fall, I can assist with the monitoring of the loading operator and the automatic shutdown of the loading process, based on a fall or no movement alarm activation. The resultant scenario can include additional tasks based on the duration of the alarm event.

One solution we designed provided a handfree portable two way voice link with the victim and an automatic trigger to shutdown the loading operation and open access barriers.
