There is no shortage as to what the Department of Labour (DoL) Inspectors would be looking at for compliance. It is often unknown that there are at least two separate inspectorate divisions at the DoL. The one most people see would be the normal Labour Inspector. But then, there is also the Health & Safety Specialists, who do an inspection on their own.
As far as the Health & Safety Specialist Inspector is concerned, he or she has a number of checklists of priorities which they would be looking for, these are publicly available from their website, here are a few examples: Safety Representatives, Noise Levels, Induction Training + Safety System Administration.

Ofcourse, as was mentioned earlier, it is important not to be confused in thinking all compliance checks are done by the DoL. Where there are employees, the DoL will be the primary inspectorate, but compliance consists of a long list of Laws, Regulations, and then even more Ordinances and By-Laws, as well as hundreds and hundreds of SANS-Standards.
