Hi all, I'm currently reviewing our spill response procedure to cover substances under COSHH and whilst I am trying to make sure we have things to deal with a spill internally (i.e. spill kits, people trained to use them, appropriate PPE, material inventory etc) that comply with the requirements under L5 COSHH Reg 13, is anyone able to confirm under what scenarios we would have to involve outside assistance (for example, the fire brigade or police department)? I can only think of scenarios that may involve a fire, notifying EPA for a substance released into the watercourse or say shutting down of a road outside if there's major gases or vapour etc. I just want to be clear on the procedure where we should be dealing with it ourselves and where we need to involve outside assistance. I believe we need to inform emergency services if we have equal to or more than 25 tonnes of dangerous substances (?) but I'm more specifically referring to an accidental release. I'm sure that's as clear as mud what I mean, but hopefully I've explained myself well enough. Thoughts please?
