cooking area, be careful to avoid steam burn, some cleaners can produce noxious fumes if
applied to a hot surface.

they can get hot.
17.a) A short power-supply cord is to be provided to reduce risks resulting from becoming
entangled in or tripping over a longer cord.
b) Longer extension cords are available and may be used if care is exercised in their use.
c) If a long extension cord is used:
1) The marked electrical rating of the extension cord should be at least as great as the
electrical rating of the appliance;
2) The longer cord should be arranged so that it will not drape over the counter top or table
top where it can be pulled on by children or tripped over unintentionally.
