Harmful substances are used in nearly every business. Some hazardous substances have legal exposure limits. These exposure limits are set by the HSE under the Control of Substances Hazardous to Health (COSHH) Regulations. While thousands of substances come under the COSHH regulations, around 500 have workplace exposure limits (WELs).Twilight Max Light Management System. Light management means delivering usable light to your eye and forming a crisp, high contrasting image. Lens coatings are applied that maximize light transmission in blue and red, and balancing colors to develop the highest possible contrast. Glare is controlled with special mechanical structures. This means you can see antler tines in dark shadows long after the competition has gone home. Broken down, this calculation is 8 hours exposure of 50mg.m-3, divided by 8 for the time-weighted average we are measuring. Pretty straightforward. But of course, in the real world, exposure doesn't always happen like this. Let's look at some more realistic examples. Example Calculations Changes in exposure What if the exposure isn't always the same level? Some parts of a process may expose employees to a higher concentration of a substance than other parts of your work. Breaks during their shift may stop exposure altogether.

We still divide by 8 to get our 8-hour average. And we still must not exceed the 8-hour WEL that is given. Shorter shiftsThere are 420 pupils in the school. Two hundred fifty-two pupils go to the 1st level. Write as a fraction what part of the pupils goes to the 1st grade and what part to the 2nd grade. Shorten both fractions to their basic form. Once you have calculated the 8-hour time-weighted average for the employee, you can compare this with the workplace exposure limit, to determine if the level of exposure is acceptable. Where the exposure limit is exceeded, action must be taken to bring exposure within the set limits for the particular substance(s). Our 500G 3×18″ Polythene Bags are food safe, and ideal for all manner of applications. You can use a Polythene Bag for dust and moisture protection through to storing sand and gravel! above the 8-hour exposure limit but within the revised time-weighted average for shorter exposure period.
