Having worked in the oil & gas fields (pun), for a while all contractor companies i have worked for had D & A policies, but rescently one client has included safety sensitive work, with either Zero or lower limits than Road Standards. The problems is whilst their staff are refered to their HR, contractors are removed & banned from site, in a change to the prevoius policy of lower site alcohol level. The worry is that a worker, who can't go to that site, is sacked, will take us to an IT. My question is given that HSE INDG 240, mentions "Safety Sensitive work" how to define it, a list of jobs would be to long and prescripive, you could add it to the risk assessments, or as we are thinking about any work that requires a written risk assessment. Any thougths, and it this the right topic forum. Pete, member of IOSH for 18 years, and a safety manager since 1996

Sorry I missed the Industrial tribunal bit: You need robust terms & conditions about D&A to say as much. At my induction ( some 10 years ago) the D&A bit alone took 30 minutes and we then had to sign a document; it leaves no doubt about the outcome of breaching clients rules.
