Health and Safety

Health and safety issues are being taken very seriously by a growing number of companies as OSHA, International, and industry standards increase. Many large US manufacturers are adopting European exposure limits as a global standard for their entire company and are exceeding OSHA Standards.

To meet these standards companies must implement a highly efficient dust and fume filtration system to filter out the harmful particulate. 

The European exposure limits these companies are targeting range from .02 – 1 mg/m3 depending on company policy, well below the 5 mg/m3 standard set by OSHA.
