The world really has gone a bit silly!
Because of this, the site operator is accountable for the safety of anyone employed, or visiting their premises. You not being directly employed by them, makes no difference, as you are still technically employed or contracted to work on their premises. They cannot simply allow you to take responsibility for an injury resulting from something you do on their premises, and in case of a reportable accident under RIDDOR Regs, the HSE wouldn’t differentiate between you as a visiting driver, and any other employee.
Some sites will protect themselves by requiring contractors to provide suitable risk assessments & method statements, and ensure all the safeguards identified are in use. Whilst others will turn a blind eye, and hope for the best. Some sites may no even appreciate their responsibilities! If you’re an employee, it’s your employer’s responsibility to provide RAs, for tasks you will perform, and not the operator of the site you’re visiting. Although it is their responsibility to ensure one has been carried out, and complied with.
I’m not claiming to agree with any of the above, or know the best answer. But I do suspect company’s policies will be the result of a significant incident, either at a site they operate, or learned of through their industry’s safety shares / learnings.
A serious injury occurring on a company’s premises can quite easily close a business, if the subsequent inquiry reveals failings contributed to the incident. A recent HSE report quoted examples of the costs to a business, following a worker being injured. For example, a broken leg costs a business an average of £250k, in fines, lost productivity, HSE ‘charges for intervention’, insurance excesses, increased insurance premiums, etc etc.
I wonder if anyone has ever costed the faffing around, in lost productivity etc…
