Best Regards Jusn Hobday NOSA Managing Director Mining in 2014 As you all know the mining industry, both locally and internaonally, is not in the best posion it could be. Locally with the work stoppages the industry is experiencing some dicult challenges. This obviously impacts on us and we need to implement change to maintain business. One of the major challenges with the industry (and any industry for that maer) parcularly in these mes is to send sta for training. Sending sta for training is a vital exercise for most companies but also a costly one. We at NOSA have extended our oerings to include a range of e-learning courses enabling learners to study from home and in their own me to alleviate the cost of travel and accommodaon when aending a classroom based course. NOSA’s well-known SAMTRAC course has been developed on an e-learning plaorm to allow anyone to complete the material in the comfort of their own home. SAMTRAC e-learning is available for both general industry learners and mining learners and is available world-wide with relevant legislaon. This is truly a world class course seng a common standard internaonally providing praccal insight into HSE management. NOSA will sll be oering the classroom based SAMTRAC course at all of our centres across South Africa as well as in-house training for clients with 12 – 20 learners. World Day for Safety and Health at Work focusing on use of chemicals In 2012 to 2014, NOSA Occupaonal Hygiene Services, a division of NOSA (Pty) Ltd, has been operaonal providing services that include monitoring of Chemical Stress Factors, Physical Stress Factors, and Evaluaon of Indoor Air Quality and Venlaon Systems. It is vital that decision makers, managers and workers themselves, as well as all occupaonal health professionals, understand the essenal role that occupaonal hygiene plays in the protecon of workers’ health and of the environment, as well as the need for specialised professionals in this eld. The main focus for this arcle will be Chemicals in the work place. Occupaonal hygiene Occupaonal hygiene is the science of the ancipaon, recognion, evaluaon and control of hazards arising in or from the workplace, and which could impair the health and well-being of workers, also taking into account the possible impact on the surrounding communies and the general environment. Chemical agents come in various forms and one must be aware of the numerous types and sources of chemicals around us, at work and at home. Chemicals can be grouped into gases, vapours, liquids and aerosols (dusts, fumes, mists). Gases Gases are substances that can be changed to liquid or solid state only by the combined eects of increased pressure and decreased temperature. Handling gases always implies risk of exposure unless they are processed in closed systems. Vapours Vapours are the gaseous form of substances that normally are in the liquid or solid state at room temperature and normal pressure. When a liquid evaporates it changes to a gas and mixes with the surrounding air. Liquids Liquids may consist of a pure substance or a soluon of two or more substances (e.g., solvents, acids, alkalis). A liquid stored in an open container will parally evaporate into the gas phase. Dusts Dusts consist of inorganic and organic parcles, which can be classied as inhalable, thoracic or respirable, depending on parcle size. Fumes Fumes are solid parcles vaporized at high temperature and condensed to small parcles. The vaporizaon is oen accompanied by a chemical reacon such as oxidaon. Mists Mists are suspended liquid droplets generated by condensaon from the gaseous state to the liquid state or by breaking up a liquid into a dispersed state by splashing, foaming or atomising. Examples are oil mists from cung and grinding operaons, acid mists from electroplang. NOSA is commied to providing soluons to manage the health, safety and general well-being of all employees. Services oered by NOSA OHS comprise the ancipaon, recognion, evaluaon, communicaon and control of environmental stressors in, or arising from, the workplace that may result in injury, illness, impairment, or aect the well-being of employees. Clients serviced include a wide variety of businesses within the governmental, manufacturing, transport, industrial and petrochemical markets.
