Why do you need a policy - is there an actual need e.g. professional drivers, trackside working or merely the desire to enforce a position of will against others?

Beware if your business relies upon flexibility from the workforce - impose a low limit and you need to consider if it is then suitable or fair to "call in" those who are scheduled off work.

BTW drink drive limits are exactly that - other forms of transport have different levels e.g. UK pilots 20mg, senior maintenace personnel 80mg, ships duty crew 25mg

Hi, we are a warehouse and distribution chain, with our own road fleet as well ,given road driving and MHE driving has potentially the same severity we were going down the route of a zero tolerance.

Seniors wanted 0mg, which I was not happy with given the Government road limits. We are after a number below the legal limit to get across the importance of driving whilst under the influence.

Personally I think if someone can impact the share price / operation of the company they should be held to significantly higher standards than those who function within the organisation so let them have Zero tolerance

Realistically what are you gaining from a tighter limit than that which those who drive to work are subject to?

Better to stick with limits that are universally understood and widely accepted by society particularly with a company I would suggest is likely to have regular need for non-directly employed drivers.

As to those who cite "safety critical" for me that would be a pilot or a ships officer, not an FLT or van driver.

Interstingly there is no limit or requirement for abstinence in medical surgeons.

I can't see any rational reason for picking something other than an existing limit - probably either an existing driving limit, or the rail limit.

I'm not sure where you're getting your rail limit.  Your figures for roads are micrograms alcohol per 100 millilitres of breath, but my understanding of the rail limit is 13 (RIS-8070-TOM, which I think you can get from https://www.rssb.co.uk, though you'll need to register an account).

Our limit is the rail limit.  About half our staff work on rail projects and theoretically could be asked to attend 'on or near the line' at short notice, so we consulted and agreed we would apply the same limit across the entire business.  Thus we have a policy of rail limit while at work, and zero consumption of alcoholic beverages while at work or on breaks (except when entertaining - then I can buy alcohol for myself or a colleague, but I can't claim for it on expenses).

For those who persist in believing all management are evil by definition, the same limit applies to every employee, contract staff, director and owner working in the business.  We do random sampling only of those in the rail parts of the business, however (but again, your chances of coming up at random are the same whether you're an apprentice or on the top board).  In principle, someone more senior could probably game the system by finding out when we are running the testing and being unavoidably out of the office that day, but I've never detected that.

Zero limits are difficult - what if it's mouthwash?  What if it was a lunchtime tiramisu?  Even if you do want zero, I think you'll need to set a deemed zero level.  Google tells me that USA 'zero' level for teen drivers is 10mg/100ml of blood.
