UK Should I be worried? Induction hob installation

[oceans247]

Last night I was cooking dinner on my induction hob. While I had my back turned to the hob I heard a lot of crackling and popping and then smoke started coming out of the master switch for the hob on the wall. It stank for fish.... It was kind of scary to have to touch the switch that was crackling and smoking. Today my landlord ask me to take measurements of the hob so they can order a new hob. I was surprised to see what was underneath.... I believe the top of the oven should not get hot enough to ignite all that wood dust, but there are fans on the bottom of the induction hob which could be sucking up this dust... Should I get an electrical inspection as if this is the standard of the electrics, it is rather worrying?

Looking at all that saw dust makes me squirm..... are you sure none has gone inside the unit?

You should see the bottom of our oven

Do you think they cut the hole for the hob with the oven in situ?
