Question No 1

REPLY BY THE SECRETARY FOR HEALTH AND WELFARE TO A QUESTION BY THE MON HILTON CHEONG-LEEN IN THE LEGISLATIVE COUNCIL ON WEDNESDAY, 14 JANUARY 1987

Question

Sir,

With regard to air pollution in underground carparks will Government inform this Council :

(a)

(b)

of the general level of concentration of carbon monoxide in these carparks especially at peak hours; and

what measures are being taken to monitor the level of concentration so as to assess the health hazards for the public and in particular for the security guards and ticket collectors working full-time in these underground carparks?

At present, no regular monitoring of carbon

monoxide levels in underground carparks is undertaken.

Reliance has hitherto been placed on the self-regulation of

building developers to incorporate adequate ventilation

systems in enclosed carparks, and guidelines to this effect are

issued by professional organizations such as the Chartered

Institution of Building Services Engineers (CIBS).

2.

A study of carbon monoxide levels in two underground

carparks has been recently undertaken by the Department of

Community Medicine of the Chinese University. This concluded

that while there were no immediate health hazards to the

public using the carparks, the attendants and security guards

might be exposed to a potential hazard.
