Default Gas hob safety cut out?

My elderly neighbour was immobile yesterday and rang me for help. I
walked into the house and there was a very stong smell of gas. Is hob
was on, with no flame, apparently from the night before when he heated
some beans in a pan.

Now I'm somewhat confused as to how come it was still on with no
flame. If he'd forgotten to turn it off the flame would still be
burning. If he'd turned it on but didn't ignite then surely it should
have cut out the gas? Our gas hob let gas through without a flame.

Or could he have done it on purpose? Worrying.

It is a Stoves Newhome DF 600 SI Dom - I can't find much about it.

If it's faulty he needs it fixed, if that' how it works he needs a gas


Why ever wait to finish a job before starting the next?

If installed in a correctly ventilated room as far as I can recall the old thinking was the rate of gas flow through the burner jet was insufficient to raise the concentration of gas in air to attain explosive levels and the stench would alert person's to the gas escaping. The introduction of flame failure devices was a safety improvement brought in later.
