Canon Oakley gas cooker safety feature?

I have had some building work done in my kitchen, had a guy checking the gas who informed me that my Canon Oakley 10518G had 2 safety features,
1. A glass top when if not raised prevents gas going to the burner
2. A cut off feature that if 1 of the burners does not ignite when all are lit then the cooker should shut off.
I have looked on the manual for some info on this issue but could not find any thing, would appreciate any feed back from the forum on this matter
