Laser cutting sheet metal


Combustible, or explosive dust, is one of the greatest threats to employee safety and facility integrity. Standardized by NFPA and enforced by OSHA, explosive dust guidelines are critical and, with expert oversight, many of the common factors attributing to its occurrence can be mitigated. IVI’s experienced team is highly skilled in this area, designing and fabricating systems that mitigate this hazard.
