Our benchtop Winged Sentries provide a flexible work space for tasks that require local exhaust ventilation (LEV).
For example, say a company wants to ship small trays of laboratory chemicals arranged in the order a lab tech uses them.
What’s more, the company wants to provide the lab chemicals in customized amounts.
Winged Sentries pull fumes away from the worker as they manipulate the devices they use to weigh and fill an order even when those manipulations differ from order to order.
Packaging solutions may produce hazardous fumes
Custom vacuum-formed trays with reservoirs could work well for chemicals, for example, because measured amounts of each custom powder could be placed into the reservoirs.
A clear plastic lid could be hot-welded to the tray to keep each substance in its respective reservoir.
And right there – when packaging involves the heating of plastics – you have a potential respiratory hazard.
Plastic welding guns produce temperatures that range from 105 – 1150° F.
High temperatures can cause polymers to break down, to thermally decompose, to produce methane, propane, carbon monoxide, and aldehydes — all substances that shouldn’t be inhaled.
It is gratifying to us that this customer is looking out for the respiratory health of the workers who will weld PVC.
