Combustible dust collectionExplosion-proof Vacuum Solutions

The Occupational Safety and Health Administration (OSHA) in the United States defines combustible dust as “a solid material composed of distinct particles or pieces, regardless of size, shape, or chemical composition, which presents a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations”.

Several deflagration in industrial environments caused by underestimation of the combustible dust hazard led to an increased attention to prevention and manufacturing standards.In fact, some materials and powders are commonly known as explosive, but other ones become combustible only when in dust form.

What is combustible dust?

How does an explosion occur?

Safety organizations, including the NFPA 654 and OSHA’s Combustible Dust National Emphasis Program, use the explosion pentagon to easily illustrate how accumulations of seemingly harmless dust can result in a catastrophic explosion. In presence of the 5 elements below, it is likely to occurr an explosion.

COMBUSTIBLE DUST: represents the fuel to burn for the explosion. It hoardS in high spot areas or out of sight areas

OXYGEN IN AIR: fire needs oxygen to burn, and it can be foundalmost everywhere.

DISPERSION: hoarded dust can easily become a dust cloud suspended in air, increasing the explosion hazard

CONFINEMENT: the dust confined in closed areas cannot be dispersed and helps the increase of dust particles concentration

IGNITION: element that triggers the explosion. The ignition sources can vary and they depends on what the dust is made from.

AGRI-FOOD DUSTS CARBON DUSTS CHEMICAL DUSTS METAL DUSTS PLASTIC DUSTS

Guidelines

NATION EMPHASIS PROGRAM OSHA gives a guidance that all industries must follow called NEP (National Emphasis Program), which lists recommended housekeeping and maintenance procedures.

Even if the NEP is not an approved regulation, this does not mean that it can considered without penalty. There are some standards that can be used for regular citations.

Recommended procedures include:• Detailed working environment cleaning program, defining the materials which may

be combustible, the processes to avoid explosions, hidden areas in the facilities that have to be checked regularly and source of ignition

• Use of industrial vacuum systems as the best and safest choice for cleaning• Only use certified equipment for the scope, both as outlined by the environment

(HazLoc) or for safely picking up the dust type (Combustible / Non-combustible) as identified in your Dust testing and DHA.

NFPA 652 - STANDARD ON FUNDAMENTALS OF COMBUSTIBLE DUST The NFPA created its own regulation in order to set standards to deal with combustible dust in industrial environments, the NFPA 652.

The NFPA 652 applies to all facilities that manufacture, blend, package, repackage, convey, or handle combustible dust or particulate solids that may become dust (even in presence of not classified environments) and states that each plant must have:

• On file a copy of their dust type testing• A complete Dust Hazard Analysis in order to prevent dust related hazards.• Documented housekeeping procedure listing these methods of cleaning

Industrial vacuum cleaners are listed as the preferred method of cleaning as they collect and contain dusts safely, guaranteeing the highest level of cleaning and hygiene (much more than blowing or alternative cleaning systems).

Regulations

NFPA 70 - NATIONAL ELECTRICAL CODENFPA set a classification of dangerous environments based on the type of risk and on its frequency in presence of combustible dust.

Other 2 regulations (NFPA 654 - Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids and NFPA 484 – Standard for combustible metals) both define combustible dust as “any fine solid material that is 420 microns or smaller in diameter and present a fire or explosion hazard when dispersed and ignited in air”.

EXPLOSION-PROOF CERTIFICATION

It is not possible to certify any equipment or vacuum cleaner by NFPA or OSHA standards, because they are not certification authorities. Only an NRTL (Nationally

Recognized Testing Laboratory) may certify equipment for use in Hazardous Locations.

Delfin industrial explosion-proof vacuum cleaners

are NRTL certified (ETL Intertek listed) and are manufactured in order to avoid any risk of ignition in a

potentially explosive environment.

Note: Pneumatic Equipment cannot be certified by NRLTs, because there is no certification for pneumatic

equipment in the United States.

HOW DOES IT WORK?Extracted powder is immersed directly into the inert oil in the container, which render inert the

metal dust.A PPL filter and a sieve grid filter the inert powder and allows to re-use the same oil several times.

3 fiber filters stop possible oil mists that may be created from suction and immersion.An overpressure safety valve guarantees system safety.
