The break-point system consists of adding enough chlorine to oxidise
the products of ammonia so that there is a "reserve" of chlorine immediately
available to attack and destroy bacteria. The concentration of
chlorine in the water may be from 1 to 5 parts per million. With this
system, however, it is very important to control the alkalinity of the pool
water within fairly close limits, otherwise conditions may become unpleasant
for bathers. The break-point system is of advantage during periods
when there is a heavy bathing load, since under the superseded system
there was usually insufficient chlorine in the water to form an effective
"reserve".
No economic system of pumping water can ensure that all parts of the
pool water are removed at the same rate, and there is a tendency to create
what are known as "dead spots" where the movement is slow. A reserve
of free chlorine is very desirable in such circumstances.
The water is sampled and tested by the pool attendants about every
two hours at the points likely to give the worst results, and during every
month a sample is taken and sent for an independent chemical and
bacteriological analysis. During the last season the results were very
satisfactory.
Break-point chlorination is also considered to give water a more inviting
and attractive appearance.
The statistics for 1951 were as follows:—
Total admissions 79,711
No. of season ticket holders—adults 125
children 557
The Pool was opened on Saturday, 28th April, 1951, and closed on
Saturday, 29th September, 1951.
PUBLIC MORTUARY
Under Section 198 of the Public Health Act the local authority may,
and if required by the Minister shall, provide a mortuary for the reception
of dead bodies before interment; a post-mortem room for the reception
of dead bodies during the time required to conduct any post-mortem
examination ordered by a coroner or other duly authorised authority;
and may make byelaws with respect to the management and charges for
the use of any such place provided by them.
A local authority or parish council may provide for the interment of
any dead body which may be received into their mortuary.
There are various regulations regarding the disposal of dead bodies,
designed to prevent the spread of infection. If the Medical Officer of
Health certifies that it is necessary, a Justice may order the body of any
person to be removed to the mortuary and, if he considers it necessary,
buried within a stated time. The Medical Officer of Health or other
medical practitioner may certify that it is necessary for the body of a
person who has died from a notifiable infectious disease to be removed
direct from hospital to a mortuary or buried forthwith.
These provisions were previously in the Public Health Act, 1875.
The Hornsey mortuary and post-mortem room are situated at the
Central Depot, Hornsey High Street. During the year ninety-six bodies
were admitted and post-mortems carried out on all of them. Inquests
were held on ten bodies.
