Pfr,
ok, I will immediately dispute all politicians - just because you say it, doesn't make it so...

Ians, the tape marks the limit of the warm zone. Outside no protection is required. The fire service is there to wash down contaminated people.
The people in yellow suits have come from the hot zone into the warm zone and are preparing to remove their suits. The bins are to receive them. The people in white suits are to assist them.
Standard procedure.
