Hi
Please can anyone help? if contractors are brought in to clean high level, what is required in terms of evidence of training? We have a company hand book that they read and sign regarding controls on site, insurance etc. But in terms of how do we know if they are trained in how to clean - what do I look for? For example, pest control technicians have training certs etc but what would contract cleaners have to show they are competent to carry out the cleaning?
Thanks
W
