The health and safety of our servicemen are of paramount importance to the Singapore Armed Forces (SAF). We monitor air quality closely, and have in place a set of Pollutant Standards Index (PSI)-Activity Guidelines under the SAF Medical Directives and Training Safety Regulations to calibrate our outdoor activities and training according to the PSI reading. This ensures that SAF troops can train safely by modifying the nature and intensity of outdoor activities according to the haze level. The PSI-activity guidelines are formulated for the SAF population and take into account their medical fitness and the nature of training activities. These guidelines are also consistent with the National Environment Agency’s health advisories based on PSI readings. For Pollutant Standards Index (PSI) reading below 100, training will continue as per normal. With the PSI exceeding 100, the SAF has reduced physical and outdoor training accordingly.
