We all want a clean Hong Kong. This could only be possible with the hard work of our cleansing workers. They help maintain a high standard of hygiene and cleanliness in our environment by properly disposing rubbish and cleansing streets and toilets.

The working conditions of cleansers are, however, not as desirable as that of many of us. Their working environment may probably be hot, humid, slippery, dim and filthy. Very often, they have to handle hazardous chemicals and refuse contaminated with pathogens. They have to lift heavy loads as well. Cleansing workers should adopt appropriate preventive measures to prevent themselves from getting hurt or contracting occupational diseases.

Prolonged outdoor work in the hot and humid summer may lead to heat stroke. It is therefore important to take measures to alleviate heat stress, such as wearing loose work clothes and wide-brimmed hat, drinking water frequently and taking periodical breaks in the shade.

Agents such as insecticides, pesticides, cleaning agents, bleaching solutions, biocides, and disinfectants used for killing insects and germs and removing persistent stains contain toxic chemicals. Improper use may harm the skin, eyes, respiratory system and other organs of the body. Good ventilation, proper usage, suitable protective measures and good personal hygiene are some of the measures to reduce the risks. Cleansing workers should adhere to safe work procedures. They should not mix different chemicals to avoid vigorous chemical reactions and the release of toxic gases.

The refuse, especially those containing organic matters, may be contaminated with pathogens. The use of personal protective equipment such as facemasks, gloves, eye protectors and protective clothing when handling refuse is one of the important preventive measures in reducing the risk of infection. Cleansers should also maintain good personal hygiene and wash their hands and body thoroughly with clean water and soap after work.

Poor postures in lifting heavy loads, such as bending, twisting and stretching, may lead to back pain. Proper lifting posture, use of lifting aids and team lifting can help prevent back injuries.

Most of the occupational accidents and diseases are preventable. The co-operation of employers and employees is the key to workplace safety and health.
