With the search and rescue operation now winding down, the authorities in West are
focussing on ensuring there are no hazardous chemicals remaining on the site,
which could be a threat to the public.
They are also trying to establish exactly what caused the fire and the explosion
that followed it.
There is little left of the factory or dozens of houses that bore the brunt of
the blast.
Police are expected to start allowing residents back into the restricted area
in the next 24 hours
so people can see what's left of their homes and possessions.
