CHP reminds public on precautions against heat stroke during very hot weather

     The Centre for Health Protection (CHP) of the Department of Health (DH) today (June 24) reminded members of the public, particularly those undertaking outdoor activities, to take heed of necessary measures against heat stroke and sunburn in very hot weather.

     “The public should carry and drink plenty of water to prevent dehydration while engaging in outdoor activities,” a spokesman for the CHP said.

     “Those engaged in strenuous outdoor activities should avoid beverages containing caffeine, such as coffee and tea, as well as alcohol, as they speed up water loss through the urinary system,” the spokesman explained.

     “Infants and children, the elderly, pregnant women, those with chronic illnesses, such as heart disease or high blood pressure, outdoor/manual workers, and individuals who are overweight are more vulnerable to heat stroke.. They should pay special attention,” the spokesman added.

     The public should adopt the following precautions:
 

  • Wear loose and light-coloured clothing to reduce heat absorption and facilitate sweat evaporation and heat dissipation;
  • Avoid vigorous exercise and prolonged activities like hiking or trekking as heat, sweating and exhaustion can place additional demands on the physique;
  • Perform outdoor activities in the morning or the late afternoon, if possible;
  • For indoor activities, open all windows, use a fan or use air-conditioning to maintain good ventilation;
  • Do not stay inside a parked vehicle; and
  • Reschedule work to cooler times of the day if feasible. If working in a hot environment is inevitable, introduce shade in the workplace where practicable. Start work slowly and pick up the pace gradually. Move to a cool area for rest at regular intervals to allow the body to recuperate.
     
     â€‹The public should also note the latest and the forecast Ultraviolet (UV) Index released by the Hong Kong Observatory (HKO). When the UV Index is high (6 or above):
 
  • Minimise direct exposure of the skin and the eyes to sunlight;
  • Wear long-sleeved and loose-fitting clothes;
  • Wear a wide-brimmed hat or use an umbrella;
  • Seek a shaded area or put on UV-blocking sunglasses;
  • Apply a broad-spectrum sunscreen lotion of at least sun protection factor (SPF) 15 – ideally higher – and reapply every two hours if you stay out in the sun, or after swimming, sweating or towelling off; and
  • While using DEET-containing insect repellents for personal protection against mosquito-borne diseases, apply sunscreen first, then insect repellent.
    
     â€‹If symptoms develop, such as dizziness, headache, nausea, shortness of breath or confusion, rest and seek help immediately, and seek medical advice as soon as possible.
     
     â€‹The public may obtain more information from the DH’s Health Education Infoline (2833 0111), heat stroke page and UV radiation page; the HKO’s Dial-a-Weather (1878 200), latest weather report and forecast, UV Index and weather information for hiking and mountaineering; and press releases of the Labour Department on precautions against heat stroke for outdoor workers and their employers when the Very Hot Weather Warning is in force.

Electrical and Mechanical Services Department very concerned about CLP’s voltage dip incident at 400kV overhead power supply system suspected to be caused by unstable weather

     The Electrical and Mechanical Services Department (EMSD) is very concerned about the voltage dip incident occurred at CLP Power Hong Kong Limited (CLP)’s 400kV overhead line power supply system connecting Yuen Long and Shenzhen in the early morning today (June 23). 

     According to CLP, it was suspected that this voltage dip incident occurred during Thunderstorm Warning, under which the 400kV overhead power supply system was affected by the unstable weather. EMSD followed up with CLP immediately. In addition to requesting CLP to identify the cause of the power supply incident as soon as possible, formulate improvement plans and submit a detailed report within four weeks in accordance with the Electricity Ordinance (Cap. 406), EMSD will also form a task force to solemnly follow up on the improvement plans proposed by CLP today. Apart from ensuring the implementation of improvement measures by CLP, the task force will also review whether CLP’s timetable for implementation of measures can be accelerated, and if there are any additional measures which can assist to enhance the capability of power supply system to withstand the impact of inclement weather. 

     Besides, the Director of Electrical and Mechanical Services will meet CLP’s senior management on a regular basis to review the progress and effectiveness of all improvement measures, and report to the Secretary for Environment and Ecology. read more
