RESPIRATORY sations is particularly important when sampling for crystalline silica as the sampling head is a cyclone, and only at low pulsation levels will it get the correct ‘respirable’ sample. While awareness of silica’s negative health effffects is on the rise, correct procedure, safety-focused culture, and the right equipment will ensure that the downward trend of silicosis mortality continues. Confined Spaces Working environments that can be classified as confined spaces, an area or vessel large enough to enter and perform work with lim- ited entry and exit potential, are inherently dangerous when there is a risk of hazardous gases being present or lack of oxygen, such as a tank, mine shaft and vaults. OSHA refers to these as permit- required confined spaces and advises that these confined spaces should be tested prior to entry and continually monitored and ventilated. When it comes to dust, the atmosphere within a confined space can provide additional challenges. The risks are potentially compounded due to ventilation issues, and therefore, there is the potential for higher concentrations of airborne dust. The require- ment for LEV becomes even more important; otherwise, the lev- els of dust will accumulate. The use of a real-time dust meter can be especially useful in this case to get an instant indication as to whether control measures are effective or additional measures are needed. Employee Awareness Employee health must remain a priority and a core component of any workplace health and safety management system. Likewise, monitoring must continue to evolve in accordance with chang- ing production methods, and the industry is already moving in a positive direction. In addition, education and training that raises workers’ aware- ness of the risks of dust exposure is integral in ensuring that they understand how to prioritize and protect their health. Tim Turney, Global Marketing Manager at occupational hygiene and workplace hazard monitoring expert Casella, looks to the future of health and safety technology.
