Plus expenses,
You have just demonstrated that that you have little understanding about SMS.
Please take the time to read and understand what it is trying to do. It is there to help you and not hinder you. It is compulsary so you will have to implement it anyway, why not get some benefit from it?
If you are running a small company, your SMS only needs to be a small document.
It is not something that has been thought of recently. This has been in use in the Nuclear and Oil industries for years, we know it will improve safety and reduce costs if used correctly.
A little advice for when you write yours, remember this is about saving lives NOT trailing extension leads and paper cuts.
Keep it simple.
Take care and good luck with your SMS.
