As the rainstorm warning has been issued by the Hong Kong Observatory, the Labour Department (LD) reminds employers and contractors that they should adopt necessary work arrangements and take suitable safety measures to protect the safety of their employees when they are carrying out electrical work or handling electrical plant.

     A spokesman for the LD said today (July 20) that employers and contractors should avoid assigning employees to carry out electrical work (like electric arc welding work) or handle electrical plant at places affected by rainstorms, and should refer to the "Code of Practice in times of Typhoons and Rainstorms" and the "Guide on Safety at Work in times of Inclement Weather" issued by the LD.

     Even if electrical work is carried out or electrical plant is handled at places not affected by the rainstorm, suitable safety measures must still be adopted to prevent electric shock as the air would be more humid. Such measures include:

(i) Ensure that all live parts of an electrical installation are isolated from the power supply source and rendered dead, and the isolation from the power supply source must be maintained as long as electrical work is being carried out;

(ii) Before carrying out any electrical work or handling any electrical plant, cut off and lock out the power supply source, then test the circuit concerned to confirm it is dead and display suitable warning notices, and issue a work permit thereafter;

(iii) Ensure that protective devices (such as suitable and adequate fuses and circuit breakers) for the electrical installations or electrical plant have been installed and maintained in good working order, and portable electric tools must be double-insulated or properly earthed;

(iv) Provide suitable personal protective equipment such as insulating gloves and insulating mats for employees; and

(v) If live electrical work is unavoidable, a comprehensive risk assessment should be conducted by a competent person and the appropriate safety precautions should be taken to remove or properly control the electrical hazards involved before such work can proceed.

     In addition, employees should co-operate with the employer or contractor to follow the safety instructions and use the safety equipment provided.

     The LD has published guidebooks and leaflets on electrical work safety. These safety publications are available free from divisional offices of the department or can be downloaded from its website (www.labour.gov.hk/eng/public/content2_8.htm).

     Should there be any questions about occupational safety and health matters, please contact the Occupational Safety Officer of the LD at 2559 2297.

Here is an item of interest to swimmers.

     The Centre for Health Protection (CHP) of the Department of Health (DH) today (July 20) 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.

     "The obese, the sick, including those with heart disease or high blood pressure, the old and the young are more vulnerable to heat-related illnesses. 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 place additional demands on the physique;
• Perform outdoor activities in the morning or late afternoon;
• For indoor activities, open all windows, use a fan or use air-conditioning to maintain good ventilation; and
• Reschedule work to cooler times of the day.

     If working in a hot environment is inevitable, introduce shade in the workplace where practicable, and start work slowly and pick up the pace gradually. Get into a cool area for rest at regular intervals to allow the body to recuperate.

     The public should also note the latest and the forecast Ultraviolet (UV) Index released by the Hong Kong Observatory (HKO). When the UV Index remains high (6 or above):
 

• Minimise direct exposure of the skin and the eyes to sunlight;
• Wear loose long-sleeved clothing made of close-woven fabrics;
• Wear a wide brim hat or use an umbrella;
• Seek a shaded area or put on UV-blocking sunglasses;
• Apply a broad-spectrum sunscreen lotion with a sun protection factor (SPF) of 15 or above. Apply liberally and reapply after swimming or sweating; and
• While using DEET-containing insect repellents for personal protection against mosquito-borne diseases, apply sunscreen first, then insect repellent.

     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.

     The public may get more information from the DH's Health Education Hotline (2833 0111), heat stroke page and UV radiation page; the HKO's Dial-a-Weather (1878 200), latest weather 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.

Attention duty announcers, radio and TV stations:
 
     Please broadcast the following special announcement immediately, and repeat it at frequent intervals when the Very Hot Weather Warning is in force:
 
     The Labour Department reminds employers that as the Very Hot Weather Warning is in force, they should assess the risk of heat stroke to their employees and adopt effective preventive measures such as providing cool drinking water, setting up temporary sunshade and providing mechanical aids to reduce physical exertion of employees. Employees should drink water regularly and be mindful of their physical condition. If early heat stroke symptoms such as headache and thirst appear, they should rest in a cool or shady place and drink water immediately. They should also inform their supervisors to take appropriate actions.
