Industrial Dust Curtains Randall Manufacturing

Dust isn’t an issue that’s taken lightly in manufacturing and food processing plants.  It’s a matter of safety. Containing dust with Randall’s Industrial Dust Curtain is an effective, easy to install, easy to move, solution.

Combustible dust is a dangerous hazard in a variety of industries, including: food (e.g., candy, starch, flour, feed), plastics, wood, rubber, furniture, textiles, pesticides, pharmaceuticals, dyes, coal, metals (e.g., aluminum, chromium, iron, magnesium, and zinc), and fossil fuel power generation. The vast majority of natural and synthetic organic materials, as well as some metals, can form combustible dust. That’s why using an industrial dust curtain is necessary in controlling the dust from spreading from one area to the next.

OSHA provides the following information on the combustibility of dust, dust control, and damage control:

Dust Combustibility 

The primary factor in an assessment of these hazards is whether the dust is in fact combustible. Any “material that will burn in air” in a solid form can be explosive when in a finely divided form.

 

Dust Control 

NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids, contains comprehensive guidance on the control of dusts to prevent explosions. The following are some of its recommendations:

  • Minimize the escape of dust from process equipment or ventilation systems;
  • Use dust collection systems and filters;
  • Utilize surfaces that minimize dust accumulation and facilitate cleaning;
  • Provide access to all hidden areas to permit inspection;
  • Inspect for dust residues in open and hidden areas, at regular intervals;
  • Use cleaning methods that do not generate dust clouds, if ignition sources are present;
  • Only use vacuum cleaners approved for dust collection;

 

Damage Control

NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids, contains comprehensive guidance to minimize the danger and damage from an explosion. The following are some suggested protection methods:

  • Separation of the hazard (isolate with distance);
  • Segregation of the hazard (isolate with a barrier);

  • Deflagration venting of a building, room, or area;
  • Pressure relief venting for equipment;
  • Provision of spark/ember detection and extinguishing systems;
  • Explosion protection systems (also refer to NFPA 69, Standard on Explosion Prevention Systems);
  • Sprinkler systems; and
  • The use of other specialized suppression systems.

 

Isolating the area where dust is originating is key.  Randall Industrial Dust Curtains are an excellent solution to containing all types of dust.  Manufactured with 13, 18, or 22 oz. flame retardant vinyl that meets California Fire Marshal, NFPA-701 and ASTM E84 Class A standards, Randall Industrial Dust Curtains are also waterproof, mildew and rot resistant. 

When controlling dust the seal is critically important.  Industrial strength Velcro® joins panels together, magnet and snap options are also available.
