c ►7.3 Complete the following extracts from the conversation by underlining the phrases
that give the strongest emphasis. Read the conversation again and check your answers.
7 Restricted areas are places where a serious danger is present. So it’s essential that these
should be kept locked at all times / all the time.
8 Under no circumstances should anyone / Nobody should under any circumstances
be able to access them ...
9 ... it's important that permits are issued each time / every single time someone enters ...
10 And it's crucial that there's just one / just a single key to each restricted area.
11 Then, while they're working, it’s vital / it’s advisable that they keep the key on them ...

Stephanie: Restricted areas are places where a serious danger is present. So it’s essential that
these should be kept locked at all times. Under no circumstances should anyone be able to
access them, unless they have a permit to work, in other words, a written form giving permission
to work in the restricted area.
Lin: And permits to work, and the keys to restricted areas, can only be issued by the electrical
supervisor?
Stephanie: That's right. So that one individual is responsible for electrical safety for the whole
plant. Only that person is authorised to issue permits to work.
Lin: Presumably, it’s important that permits are issued every single time someone enters a
restricted area - each time they do a new job, they need a new permit.
Stephanie: Exactly. They shouldn’t be issued for any longer than a full shift.
Lin: OK.
