Beware of impostors when it comes to combustible dust and explosion-proof equipment!

Friday, July 1st, 2011

ImpostorWhen it comes to combustible dust housekeeping, choosing the right cleaning equipment can be a difficult decision. There are many options to choose from & the purchase of a properly-equipped industrial vacuum cleaner that can safely minimize dust accumulations should be viewed as an investment that will keep workers safe & regulatory agencies out of your facility. 

But beware of impost0rs! There are fellow vacuum manufacturers who are “muddying the waters” by making false claims. One example is a company who has been touting their air-operated vacuum cleaners as approved by an OSHA NRTL (nationally recognized testing laboratory) and referring to them as “explosion-proof.” Unfortunately, this simply isn’t possible. At this point in time, only electric equipment can be approved or certified  “explosion-proof” for hazardous environments. There are no recognized product safety standards or organizations  in North America that certify air-operated or pneumatic equipment for use in hazardous locations.

 We’ve also heard companies mislead folks by stating or implying that their equipment is “OSHA Approved” or “OSHA certified.”  OSHA does NOT certify, recommend, or approve any type of equipment.  It is simply their role to develop, regulate and enforce health and safety rules and guidelines in the workplace. 

As a reminder, here is what you SHOULD look for when choosing an EXP vacuum for hazardous locations.

  • True explosion-proof/dust ignition-proof vacuums should be engineered from the ground up to prevent combustible dust explosions.
  • All parts should be grounded and built from non-sparking materials – from the outer shell to the switches, motor, filters, and accessories
  • Manufacturers should be careful of vacuums that are promoted as explosion-proof, but are really only standard models with a few antistatic options added on
  • OSHA does NOT certify or approve any vacuum cleaner. Only Nationally Recognized Testing Laboratories (NRTL), such as the Canadian Standards Association (CSA), has the authority to certify vacuum cleaners as explosion-proof or dust ignition-proof.
  • When electricity is unavailable or undesirable, safe pneumatic vacuums are excellent alternatives to electric explosion-proof vacuums
  • All pneumatic (air-operated) vacuums are not explosion-proof vacuums
  • Safe pneumatic vacuums should be constructed of non-sparking materials, like stainless steel, with ignition-proof parts that meet the highest level of operational safety

Free Webinar: Combustible Dust Preventative Maintenance: More than just Housekeeping

Date of event: 3/15/2011

In recent years, the 5WSL overhead pipeOccupational Safety and Health Administration (OSHA) has set their sights on combustible dust, naming it a high regulatory priority and issuing a National Emphasis Program with guidelines and recommendations for decreasing the risk of combustible dust fires or explosions in industrial settings. As a result, manufacturers are being closely monitored by the agency through random audits and being dealt hefty fines for not taking the necessary preventive precautions.

Join this webinar to learn how facilities can significantly reduce their risk of costly violations, and most importantly, a combustible dust accident, by instilling best engineering practices that include a solid maintenance plan to eliminate dangerous dust accumulations on floors, walls, machinery, and overhead areas.

This interactive webinar will:

  • provide a basic understanding of the combustible dust issue,
  • discuss critical housekeeping tips and recommendations as they pertain to Nilfisk Industrial Vacuum’s firsthand experiences,
  • include a tutorial on choosing a “properly-equipped” industrial vacuum cleaner, as required by OSHA.

Don’t Forget Combustible Dust During Fire Prevention Week

Tuesday, October 5th, 2010

Fire Prevention WeekEven though NFPA’s fire prevention week  (October 3-9) primarily focuses on fire safety in the home, we want to remind you that it doesn’t stop there.  Fire prevention and safety is just as important in the workplace.  These past couple years we’ve all heard a lot about combustible dust explosions in the industrial sector…but in the words of John Astad, “it’s the fires stupid.”  Below is Fired Up, an article that ran in the December edition of Occupational Health & Safety magazine written in conjunction with Mr. Astad. Thanks again to John for his help.

FIRED UP: Combustible Dust Raises Explosive Issues

By now, most manufacturers are familiar with the story of combustible dust. They’ve read about it in the newspaper, ‘Googled’ it online, watched it on CBS’s 60 Minutes special[i] , or received a letter from the Occupational Health and Safety Administration informing them their facility is considered high-risk for a combustible dust explosion. They have a solid picture in their minds of what an industrial explosion scene looks like; the remnants of a facility, a gaping whole, a collapsed roof, workers covered in soot and blood. It’s like a well-crafted movie scene; except, its real-life. 

Combustible dust has been the culprit of deadly work-place blasts for decades, but it wasn’t until an explosion in 2008 that killed 14 people at The Imperial Sugar Refinery in Port Wentworth, GA, that the issue began getting the attention it deserved.  OSHA stepped in reissuing its Combustible Dust National Emphasis Program and the industrial world became inundated with statistics, definitions and preventative measures.  (more…)

We have a new combustible dust brochure!

Friday, September 24th, 2010

In response to OSHA’s increased focus on combustible dust, we’ve  updated our Hazardous Location brochure, dedicated to industrial vacuum cleaners for combustible dust preventative maintenance. 

The Industrial Vacuums for Hazardous Locations brochure is a 4-page, full-color piece that provides you with valuable up-to-date information regarding hazardous locations and tips to prevent a combustible dust fire or explosion through proper cleaning procedures.  Of course it includes overviews of our certified explosion proof/dust ignition-proof line of vacuum cleaners, plus a list of explosive materials the machines are capable of collecting, like aluminum, ethanol and sugar dust.

The brochure is posted here: Nilfisk CFM’s Brochure on Combustible Dust Preventative Maintenance.

Combustible Dust Ground Zero: The Real Story

Thursday, August 5th, 2010

I came across this archived article today and thought it was still worth sharing.  Written 5 months after the Imperial Sugar Factory tragedy, this Savannah newspaper article paints a dreadful picture of the blast heard ’round the world and really puts the incident into perspective. Imperial Sugar was not just an incident that brought combustible dust to the headlines, awaking the regulatory giants; it was a small town disaster, with lives lost, people injured and countless more emotionally scarred forever. 

A Tragedy Born in Dust

From savannahnow.com, Savannah  Morning News

From the second the massive fireball shot into the night sky Feb. 7, the explosion at the Imperial Sugar Co. refinery became much more than a local tragedy in a small company town.

Bright orange flames were visible 20 miles from the Port Wentworth plant. The secondary blast, about 7:20 p.m., was so bright it was easily recorded on a security camera a couple of miles away at the Georgia Ports Authority.

Smoke billowed 2,000 feet into the night air and was so thick, air traffic controllers picked it up on their radar.

At ground level, it was pure terror.

The concussive force knocked employees in adjacent work areas off their feet. As they rushed to respond, little was recognizable.

Walls were blown away.

Floors buckled.

Fire rolled in waves along the ceiling.

“I saw some horrific injuries,” said Tony Holmes, a forklift operator. “People had clothes burning. Their skin was hanging off.”

****

Within minutes, the response spread far beyond Port Wentworth and its 3,500 residents.

Firefighters, police officers, emergency medical assistance crews and other responders converged from Savannah-Chatham, Effingham and Bryan counties – and beyond.

Initial reports indicated as many as 100 people might have been killed. The plant employed 352 people, plus 120 contract workers.

Eight died in the initial blast. Five more succumbed to their burns. Three of the 20 patients treated at the Joseph M. Still Burn Center in Augusta remain hospitalized there today.

More than five months after that horrific night, Port Wentworth Fire Chief Greg Long still has to push back the images and the sounds of disaster whenever he drives along the plant’s winding entry.

“I still get the same feeling every time I drive down Oxnard Drive,” he said. “I still get that eerie feeling, and the hairs stand up on the back of my neck.

****

Because of disaster response planning, emergency department personnel quickly mobilized at St. Joseph’s and Candler hospitals as well as at Memorial University Medical Center.

Gurneys lined the hallways or stretched into parking lots as doctors, nurses and other medical workers waited for the burned and injured to arrive.

They came in waves – some in ambulances driven by police officers so the paramedics could focus on stabilizing the patients as they were transported.

Memorial treated the majority, handling more than 30 burn victims the first night. Ten were flown or taken by ambulance to the burn center in Augusta.

Patty Fletcher, a registered nurse at Memorial, later would write to the Savannah Morning News that she was “in awe” of the well-coordinated response.

“Within minutes, the disaster plan was put in motion,” Fletcher wrote. “Staff, from some of the top administrators who had been at an event and arrived in tuxedos to environmental services who were at home eating dinner, started appearing from everywhere to help.”

****

Help came in so many other ways.

Neighbors rushed to churches, opening sanctuaries for those who needed to pray or needed solace.

In Chatham County and beyond, blood donors by the thousands rolled up their sleeves and held out their arms to help supply burn victims with massive amounts of blood that they would require daily.

“There is a moment in every community’s life that defines its character,” explained the Rev. Sam Self, pastor of First Baptist Church. “We reached a moment where there was such a unity. We had strangers walking up asking, ‘What can I do?’ ”

Gerald Schantz, owner of Gerald’s Diner, organized a barbecue fundraiser for burn victims’ families. In a single afternoon, he raised $22,000.

The United Way of the Coastal Empire assumed the largest fundraising role. By the end of March, the United Way had raised more than $1 million.

A fundraiser today featuring former Harlem Globetrotters standout Meadowlark Lemon and other teammates will benefit the United Way fund.

****

Most of the money raised will help support the burn victims and their families.

For them, recovery will mean months, if not years, of painful skin grafts, physical therapy and the constant risk of infection.

From the first days, the family members and friends making daily trips to Augusta reached out to each other.

“I think you see kind of a community forming in the waiting room,” said Glen Burnsed, who was visiting his injured brother-in-law. “I don’t know if camaraderie is the word, but there’s a lot of helping each other out and kind of sharing each other’s stories on how their loved ones are doing.”

Burnsed’s brother-in-law, Kelly Fields, later became the first burn victim to die of his injuries.

Walter Byron Maxwell and Troy Bacon left the burn center two months to the day after the explosion, and they motivated each other in their rehabilitation sessions at Memorial.

They do what they can to show their thanks to the community, sometimes attending blood drives so donors can see how their efforts help.

Combustible Dust Housekeeping 101

Tuesday, July 27th, 2010

Keep it clean and there will be no dust.
If there is no dust there will be no fires
If there is no dust there will be no dustcloud
If there is no dust cloud, there will be no explosion

Robert Zuiderveld impressed us with the above rhyme during a recent combustible dust discussion on Linked In, but don’t be fooled by the poetic inspiration. Linked In’s Combustible Dust Policy Institute group is one of the most valuable combustible dust forums on the web. Aside from private consultants and combustible dust equipment suppliers (like us!), active members of the group include the people who’s voice really needs to be heard…manufacturers affected by combustible dust. Posts range from questions on best practices, to combustible dust statistics, to some healthy venting on government agencies and personal experiences. But in all cases, the conversation is honest, personal, and unfiltered.  So, if you haven’t already, join the discussion (Not a member of the professional networking site? Shame on you! Sign up…it’s worth it.)

Some things recently overheard in the combustible dust group:

  • According to media accounts there were 100 combustible dust related fires and explosions in 2009. 17% of these  incidents were dust explosions with the majority of all incidents occurring in national industries (NAICS) not recognized in Appendix D-1 & D-2 of the OSHA Combustible Dust NEP.
  • OSHA fines are like monopoly money. The large companies aren’t affected by them, because they can afford it.  The small companies aren’t affected by them because they will never be able to pay it.
  • Looking for a suggestion on a violation pending with OSHA. We were cited on two dust collectors in our shop…this is not a good financial time.

PRB Coal has many advantages; combustibility is not one of them

Tuesday, July 20th, 2010

While there are many materials that fall under the combustible dust category that make you think, “really, that’s combustible?,” coal dust is certainly not one of them.  And unfortunately, the coal industry’s attempt to use a more advantageous type, Powder River Basin (PRB) coal has only increased their combustible dust risk. Found in southeast Montana and northeast Wyoming, PRB coal has a lower sulfur content and is more plentiful than traditional  appalachian bituminous coal. It’s also more combustible. Producing more dust than regular bituminous coal, it has low BTU and high moisture content, making spontaneous combustion a real concern. In fact, small fires are reported almost weekly in the industry.  The PRB coal-user’s group has addressed the issue by developing stringent recommendations and practices for fire-prevention. These include guidelines on CO2 monitoring, coal storage,  and of course best maintenance practices.

The NFPA also addresses coal in NFPA 120 Standard for Fire Prevention and Control in Coal Mines. There is also a chapter on coal dust in NFPA 850, Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations that addresses:

 

 

 

  • coal storage and cautions about spontaneous heating and how that can be limited in the coal pile storage through separation of different types of coal that are not chemically compatible, working the pile to prevent dead pockets of coal, and locating the pile away from heat sources
  • storage in bins, silos and bunkers including the provision of dust tight barriers between boiler houses and the area above the silos, bunkers, or bins
  • dust suppression and control including methods to control dust, proper cleaning methods, warning against the use of vigorous sweeping or compressed air and the use of listed vacuum cleaners for the dust environment or the use of low velocity water
  • coal conveying and handling structures with attention to designing the structures to limit the ledges for the accumulation of dust by utilizing beam shields or placing the structural members exterior to the building; the section also addresses the use of approved equipment in the areas, the electrical classification of the areas and means to reduce the hazard of static electricity through permanent bonding and grounding
  • fire protection being recommended in coal handling structures, conveyors, bag-type dust collectors

 

 

Combustible Dust Stakeholder Meeting A Success

Tuesday, July 6th, 2010

Last week, OSHA held their first ever virtual stakholder meeting to gather more input on the proposed combustible dust rule.  The informal chat was just like any other “chat room,” with OSHA posing 4 specific questions (see below) to attendees. Not surprisingly, it seemed that most attendees ignored OSHA’s specific (and technical) questions and instead opted to address other aspects of the rule.  Also not surprisingly, the #1 question was “when can we expect to see a rule.” (Answer: it’s going to take time.) For your convenience, we’ve posted the entire transcript of the stakeholder meeting below.  It can also be accessed here.

Occupational Health and Safety also has a great summary of the event, here: http://ohsonline.com/articles/2010/07/05/parts-of-dust-standard-likely-to-be-retroactive.aspx?admgarea=news (more…)
