DUST EXPLOSION PREVENTION USING EXPLOSION VENTS AND DUST COLLECTOR SYSTEMS

 

Tuesday, April 28, 2015


Are you aware of the many potential hazards dust can bring to your workplace? If so, then you should talk with your managers and safety officers, especially if you are working in these types of workplaces and industries: 

  • Chemical manufacturing such as rubber, plastics and pharmaceuticals
  • Coal-fired power plants
  • Food production
  • Grain elevators
  • Metal processing such as zinc, magnesium, aluminum and iron
  • Recycling facilities including plants processing paper, plastics, and metals
  • Woodworking facilities

The Dangers of Dust

Dusts are created when materials are:
  • Transported and handled
  • Processed and polished
  • Shaped and grounded
  • Cut and crushed
  • Mixed and sifted



How do you plan to keep it safe?

Dust explosion prevention 

in the workplace

Keep your workplace safe from potential dust explosion. Learn how you can eliminate dust and secure safety within your premises with these helpful tips and recommendations.

Elimination of potential "danger spots"

Prevention is better than cure and for dust explosion prevention, eliminating these horizontal spaces and hidden areas could mean saving your employees life. These spaces and areas include:
  • Light fittings
  • Window
  • Beams
  • Ledges

For cleaning, avoid using brooms or compressed air hoses. Instead, use industrial vacuums approved for dust collection such as Pneuvay Engineering's AirVac unit.

Substitution of rough surfaces 

with smoother ceilings

Rough surfaces attracts more dust. Replace these with smooth ceilings to minimise dust accumulation and to make regular cleaning easier and more efficient.

Hiring an expert dust collection 

engineering company

You need an expert company with years of experience installing reliable dust collection systems that knows how to appropriately design and install dust collection and extraction systems. They should be able to:

  • Choose suitable electrical and ventilation equipment and locate dust collectors outdoors
  • Use dust collection systems with the inlet located as close to the dust producing process
  • Reduce or eliminate sparks from static electricity through bonding and grounding of equipment 
  • Remove open flames, sparks, friction, heat sources, and other sources of ignition
  • Wrap covers around pipes and cables, or embed pipes and cables in the walls, where possible, to reduce surfaces where dust can accumulate

Installing explosion vent and 

pressure relief systems

One of the most common explosion protection strategies is the installation of explosion vents. These help by directing explosions along a path that has been designated to be kept clear or minimised for usage rather than explode in all directions. Explosion panels have the ability to save many lives. 

Choose a company that is skilled and experienced in the design and selection of the appropriate explosion vents. Check if they have the engineering capabilities to verify the recommended explosion vents and proposed installation designs panels meet standard requirements?

Pneuvay Engineering represents STIF, the manufacturer of the VigilEx range of explosion vents. STIF is a global leader in the design, manufacture, supply, certification and installation of explosion vents. They use advanced cutting machinery, presses and other metal working machines to ensure all of their products and services deliver as required. Moreover, they test their vent panels according to EN 14797 and manufacture these under the CE Examination certificate type INERIS 08TEX0038X.

Scheduled inspection, repair and maintenance 

Dust collection and explosion venting efficacy in preventing and reducing impacts from dust explosion depends on their ongoing performance. Regular inspection, repair and maintenance of your dust collection systems and explosion vents or panels is required. 

Pneuvay Engineering's service department delivers cost-effective dust collector repair and maintenance services which includes:

  • Keeping all electrical and mechanical equipment in good repair
  • Regularly inspecting all grounded and bonded equipment to ensure the bonds are in good condition
  • Checking equipment that may wear such as bearings and valves

Establishment of safety practises regarding 

dust in the workplace

Ultimately, you need to establish clear administration protocol in the workplace to avoid dust accumulation. Do this by:

  • Developing and implementing a combustible dust inspection and control program that would clearly outline inspection frequency and how dust would be controlled
  • Developing an ignition control program to reduce, if not eliminate, potential sources of ignition
  • Educating all employees about combustible hazards and how they can help eliminate the risk of fire and explosions in the workplace
  • Implementing the housekeeping program to ensure dust is regularly removed
  • Using proper equipment and techniques when cleaning dust


Following these recommendations would lessen your workplace's risk of dust explosion. Ask the experts. Contact us, today.
