Sealing (or hacking off the plaster, sealing and replastering) is essential because it is likely that there is soot between bricks and soot is hygroscopic. If you clean really well you may not get staining immediately but after a while damp patches will appear
I agree with the examples you use, but the Act does apply to some instances outside the workplace. The (often missed) important word is etc. The full name of the Act is; The Health and Safety at Work etc Act 1974 .
Check the thickness of the riving knife and the blade. If the blade is thinner than the knife it will bind. In use this appears to the eye as a mis-aligned knife or fence. Check the knife is not bent. I don't know your saw, but usually you can fit shims into the fastening box for the knife to...

In 1975 a colleague played with a massive heat store in the cellar of his old house. It was filled with common salt. It...
This depends upon the age of the drain (see law on combined drains (etc)
On a slightly different tack, you need to carry out a proper survey; without measuring from a proper datum the differences from ground level will lead you astray. Never put your sump in the cellar - all hell will break...
