All Staff and Students

Dear All Staff and Students,

According to the forecast of Hong Kong Observatory, Super Typhoon “Mangkhut” now over the western North Pacific will enter the South China Sea this Saturday and move quickly towards the coast of Guangdong.  As “Mangkhut” has a large circulation with intense winds, it will pose considerable threat to the coast of Guangdong.  The maximum sustained wind speed of “Mangkhut” near the centre is about 240km/hr (equivalent to a Category 5 hurricane in US), and is expected to remain above 200km/hr when it is edging close to Hong Kong.

We strongly advise all staff and students to keep up vigilance against the threat of “Mangkhut” and stay tuned with the weather forecast and safety precautionary measures issued by the Hong Kong Observatory.
In addition to the safety measures suggested by the Hong Kong Observatory, you are strongly advised to take the following precautionary measures.

For all staff and students

  • For staff members, please follow the section “Tropical Cyclone Warnings” of the Staff Handbook regarding duty arrangements in case of tropical cyclone.
  • Where required, loose outdoor items should be secured or brought indoors.
  • Close and lock all windows.
  • Close all exit/entrance doors and lock them, if required.
  • Remove items which may pose a fall risk away from the windows.
  • Stay away from exposed windows and doors because glass, already under strain from wind pressure, will shatter easily if hit by a flying object.
  • Switch off non-essential electrical appliances.
  • Do not touch electric cables that have been blown loose.
  • Make sure you have a safe indoor place for shelter when No. 8 signal or higher is in force.

For laboratory users

  • Update lab personnel and researcher contact numbers and make them available to the Campus Control Centre, if appropriate.
  • Take proper precautionary measures on equipment which has been used for handling hazardous substances to prevent potential leakage or spillage of hazardous substances due to the possibility of power interruption or suspension.
  • When No. 3 signal is hoisted or when the Observatory announces that a No.8 signal is about to be issued, complete all running experiments as soon as possible.   DO NOT start any new experiments involving biological cultures, hazardous substances or prolonged heating.
  • Before leaving the laboratory, please check the area and ensure:
    • all chemicals have been moved to appropriate storage locations and away from windows;
    • all gas cylinders and gas lines have been shut off and secured;
    • sashes of fume cupboards have been closed completely;
    • non-essential equipment have been switched off; and
    • all hazardous materials, wastes and equipment have been kept off the lab floor.
