Combustible dust explosions are a risk in many areas of a
plant—but one of the most common locations is in the dust
collection system itself. How can you know if your system
complies with local standards? What steps should you
take if it doesn’t? To minimize risk to your employees, your
property, and your business, it is essential to identify and
resolve potential explosion hazards as soon as possible.
Praxair's experts can help you identify and plan for
compliance with all applicable combustible dust health and
safety requirements. Our MetFab Productivity Specialists

cost-effective solutions.
