I have just read the article on retaining the River Hull (NCE 29 July) and was amazed to see the accompanying photograph.
While I am not aware of the details of the site, I feel sure that the operative shown is non compliant with health and safety procedures.
The basic ones, evident from the photograph are:
lNo head protection worn, normally a must on site and also when climbing.
lA two rope access system appears to be in use. Both ropes are the same colour when normal practice is to use different colours.
lNo high visibility jacket worn (although this may not be essential in this case).
lNo life jacket worn for working over water.
I would be interested to read the method statement and risk assessment for this operation.
