Posted By Paul Leadbetter David The first thing to consider is whether the work can be done without having to go into the confined space. If the confined space has to be entered, you will need to carry out a risk assessment; see the Confine Spaces Regs ACoP for details of the risks that must be addressed. Paul

Posted By Stuart Nagle David. In addition to the above, competent employees and permit to work system. Are you or your people trained and competent, if not then you need to be trained up. As far as atmospheres go, confined spaces have a range of hazards, not only whats already in there, but also what could get in there from outside (the classic being vehiklce exhaust fumes from engines left running on site on these brisk cold mornings!!) The regulatioins provide guidance on gas, fume and vapour you are lilley to find in confined spaces, including the lack of oxygen, but rather than go on about it here, and without being rude, what appears your lack of experience in this area, I would suggest the following: 1) Organise some training with a training provider who knows what their talking about - the local Water Authority would be a good place to start. 2) discuss the tasks, location, construction type (manholes) and known problems with someone who is experienced in confined spaces working 3) Find out about the permit to work system that should be operated and safe systems of work that need to be employed, including rescue in the event of an emergency, PPE RPE etc 4) Dont attempt or be tempted to do any work that is beyond your capabilities or experience in this area - confined spaces do killl - no second chances... and (5) make sure your training will include sufficient detail on gas monitors and gas testing ect (sometimes overlooked by the lesser training providers), and that you are fully familiar with any gas monitoring equipment and how it should be tested (prior to use) maintained and employed before you attempt to use it on site....
