Bunnings slips, trips and falls Peter, this is an example of the perception problems that dogged the UK HSE for years and how the media is hungry (pun not intended) for colourful news stories.
I know that greasy food on floors is a potential hazards and so Bunnings' decision has some logical merit BUT I suspect that the extent of the hazard is overstated and I support your comment that Bunnings needs to be more explanatory about its decision.
This explanation could include:
- the number of slips incidents related to food (not specifically onions, I am being generous), and
- whether the incidents involved employees or customers.
The latter point is to identify whether any injuries have been addressed under workers compensation or public liability.
And, of course, the directive to redesign the sausages and onions is, in OHS terms, an Administrative Control. Bunnings may look at stripping the concrete areas around the barbecues of the build-up of grease (if they don't already) or regularly rotating the barbecue location between both major entrances (most Bunnings have a double main entry).
IF the hazard is serious enough to instigate a change in an official change in onions, Bunnings should have reached this decision after a risk assessment process. It would be fascinating to see this process not for the purpose of mocking but to illustrate how all hazards can be subjected to assessment and how Bunnings came to the onion redesign as the most appropriate control measure.
Disclaimer: I sometimes eat sausages from Bunnings and have cooked sausages and onion twice as a volunteer for charity.
