For example, within a\nperiod of time (often 8 hours, but sometimes as short as 15 minutes), you are\nonly allowed to be exposed to a certain amount of a hazardous substance, before\nit begins to have an adverse effect on you. <\/p>\n\n\n\n<p>Exposure limits are in place to control the\neffects of substances, depending on the nature of the substance and the effects\nof exposure. Some effects require prolonged exposure, while others may be seen\nafter brief exposures.<\/p>\n\n\n\n<h2>What does WEL Measure?<\/h2>\n\n\n\n<p>Workplace Exposure Limits simply measure\nthe average length of time that it is safe to be exposed to a hazardous\nsubstance for. The two main reference periods for these averages are 15\nminutes, which is known as the <strong>short term exposure limit<\/strong> (STEL); and\neight hours, which produces the long term exposure limit (LTEL). Eight hours\nwas chosen for the LTEL as the length of a typical working day in most\nindustries.<\/p>\n\n\n\n<p>As well as this, the Workplace Exposure\nLimits also measure the amounts of the substance that one can be in contact\nwith, before detriments to your health begin. This is done by using the PPM\n(parts per million), to measure the concentration of the substance in question.\nAll of these different measurements combined are what the Workplace Exposure\nLimits use to measure how much of a hazardous substance you can safely be\nexposed to in the workplace.<\/p>\n\n\n\n<p>When dealing with substances and materials that\nare measured with the Workplace Exposure Limits, it is vital to make sure that\nyou have the right equipment to deal with and manage these substances, such as\nusing a <a href=\"https:\/\/www.manutan.co.uk\/en\/key\/coshh-cabinets\">COSHH Cabinet<\/a>\nor <a href=\"https:\/\/www.manutan.co.uk\/en\/key\/coshh-cabinets\">COSHH Cupboard<\/a>\nto store these substances.
