prepared by the Medical Officer of Health, shewing the
methods adopted for disinfection by heat in thirty-five
Metropolitan districts.
" In twenty-five instances steam disinfection is carried out
under the direct control of the sanitary authorities; in one case,
disinfection is carried out by dry heat, in another, the Vestry
was constructing a station, in three cases the authorities make
use of apparatus provided for adjoining parishes; in one case,
that provided at a local hospital, and in four instances, exclusive
of Battersea, steam disinfection is carried out by contract."
Your Sub-Committee have visited three of the stations,
viz.: at Camberwell, Lambeth, and Newington.
At Camberwell, a Goddard, Massey and Warner machine
is provided. This system your Sub-Committee found would be
totally impracticable for the requirements of this Parish.
At Newington, where in 1899, the Parish had a population
of 123,183, a Manlove Alliott (Washington Lyon) machine,
vacuum arrangement is provided. (This machine is manufactured
in three sizes). By the courtesy of Dr. Millsom, the Medical
Officer of Health, the working of the apparatus was fully and
practically demonstrated. Steam disinfection is there carried
out after all cases of infectious disease, and it is found that
the apparatus is capable of effectually dealing with the whole of
the articles. The process of disinfection occupies from 40 to
50 minutes, the temperature reached during the operation being
240° f. under a 10 1b. pressure in the steam jacket. The
temperature is subsequently reduced to 160° f. for the purpose
of creating a vacuum, and finally raised to 260° f. under a 20 lb.
pressure. An incinerator for the destruction when necessary
of infected articles is also provided, distinct from the dustdestructor,
which immediately adjoins. The Parish Mortuary
and Coroner's Court is situated on the same site, and it is found
a matter of great convenience that they should be in so close
proximity.
