Safety precautions for throw-ins.

As far as I'm concerned the following is a must:

• Plug yor bars
  
• Plug the end of your mallet
  
• Exposed chainrings must be covered/removed (if removed, the spider exposed arms can't stick out)
  
• Mallet head shouldn't have a sharp/sticking bolts or bits of plastic
  
• Cable ends should be crimped
  
  

The other points are optional
I reckon this thread needs bumping.
