Bedding is disinfested by steam, the rooms are fumigated with sulphur
and subsequently sprayed with an insecticide prepared in the department,
while the bedsteads and springs are flamed with the blow lamp.
Re-inspections are made after three months, and these visits have
proved that the system adopted is efficient.
SMOKE ABATEMENT.
During 1936, 150 observations were made of the emission of smoke
from factory chimneys, these observations varying from 30 to 60 minutes.
In 15 instances preliminary notices were served for contravention of
the byelaws; 6 of these notices were concerned with the discharge of grit
which comes under the definition of "Smoke." In one instance a Statutory
Notice was necessary in connection with the grit nuisance, and work
is now in hand which, it is hoped, will effect a remedy. The discharge
of black smoke is a waste of fuel, as well as being injurious to health.
It is usually due to careless stoking, and preliminary notices drawing
attention to the evil invariably bring about improvements both in methods
of stoking and appliances.
