What creates the dilemma are the risks associated with exposure to these chemicals. The pesticides that help grow food by producing more and better crops may result in adverse health effects in workers involved in producing the pesticides, in applying them in the fields or exposed to their residues. Residues of pesticide production and use may also cause adverse ecological effects persistent in the environment for many years after use. Over the years, chemical safety has become one of the areas in which more work has been carried out in the field of occupational safety and health (OSH). However, serious incidents continue to occur and there are still negative impacts on both human health and the environment. Extent of use of chemicals in the workplace Chemicals are readily associated with industrial facilities such as petrochemical refineries, construction sites or automobile manufacturing. A number of chemicals, such as paints, lacquers, thinners, adhesives, crystalline silica, and welding fumes are just some of the chemicals to which workers may be exposed in workplaces in the construction sector. However, virtually every type of workplace in every sector uses chemicals, and thus a broad range of workers are potentially exposed. Therefore, chemicals are a concern in every type of work performed. There are some sectors that have a special impact on the environment, and this must SAFETY AND HEALTH IN THE USE OF CHEMICALS AT WORK World Day for safety and health at work 28 April 2014 SafeDay be considered when designing preventive programmes. For example, in the agricultural sector, pesticides are applied in the environment to crops, and thus are immediately released into the air, or can travel to water sources or persist in the ground for many years. The worker applying them may be immediately exposed, but the potential exposure of others in the surrounding community must also be accounted for in determining how to perform this operation safely. ILO Convention on Safety and Health in Agriculture, 2001 (No. 184) and its Recommendation (No.192), provide for risk assessment measures and the sound management of chemicals in agriculture. The unintentional mixing of chemicals in the workplace can cause hazardous emissions 43 ingenieur 2014-July-FA.indd 43 7/9/14 10:37 AM
