Every month should be a safe month. But in June, the National Safety Council (NSC) gives a safety shout out to reducing injury or death in areas in which we spend the most time - on the road, at home and work. As part of the month’s activities, NSC provides free educational materials and articles associated with a weekly theme.

Aligning with the message of “Falls Week,” VAA continues to offer its employees OSHA 10 training. Almost 70% of the firm has completed the OSHA 10 training course since the inception of the VAA Safety Program in 2015. The in-house sessions teach individuals to recognize hazards and protect themselves from injuries in the workplace. At VAA, the focus is on jobsite hazards and the conduct expected from employees visiting these locations to promote safety.

“Our priority is the health of our employees,” said Program Safety Manager, David Olheiser, PE. “As a company, we offer individuals training to instill confidence and comfort when on site. The value is in being aware - from using fall protection to recognizing confined space constraints and electrical hazards to OSHA rules and compliance.”

Additionally, VAA recognizes the value of safety and ergonomic health in the office. A pervasive improvement to office tools began in 2016, including availability of converting sitting-to-stand-up desks and continued tweaks to lighting, seating, work surfaces, etc. “There is a balance that has to take place to ensure we’re using resources effectively,” noted VAA’s IT/Facilities Manager, Nat Schmidt. “That said, we’re always watching for proven methods and recommendation from employees and vendors on what we can do to enhance employee health while working.”

Part 3_NFPA 652 Article Image.jpg

To conclude VAA’s three-part series on the changing NFPA 652 guideline, we focus on a few compelling reasons to start moving your facility toward compliance.

 

The continued development and updates of the NFPA guidelines are, at least in part, developed as a result of past, unaddressed facility hazards. As a preventative measure and code improvement, NFPA 652 recommends DHA inspections are conducted once every five years. However, only some state and local jurisdictions have adopted NFPA 652 as a requirement.

 

It is important to note the relationship between NFPA guidelines and the International Building Code (IBC). IBC dictates the industry standard and references other guidelines to bring new versions into their requirements. NFPA 652 is not yet directly referenced in the current IBC requirements. While this means DHA’s are not currently required by the IBC, there are a few compelling reasons to get ahead of the regulation.

 

  1. Safety
    Tracking and mitigating the accumulation of dust at your facility is critical to the safety of the operators. A DHA can help prove a facility is compliant or identify areas of concern and offer solutions. The painful results of ignoring potential dust hazards can include costly equipment failure, dust deflagration and, most importantly, loss of life.
  2. Project Schedule
    Depending on the local codes and jurisdictions, Code Officials may be working from the new guidelines. In that case, officials can deny a building permit if a DHA has not been completed. The delay will set new facility and expansion projects back in time and expense.
  3. Expert Predictions
    Based on the trend of previous updates, it is likely that the 2016 edition of NFPA 652 will be standardized and referenced in the IBC code by 2021. Keeping up with dust hazards and related guidelines will lead to safer facilities and fewer future project / maintenance hassles.

Part 2_NFPA 652 Article Image.jpg

The three-part series continues explaining the forms a DHA can take in existing and new facilities or expansions.

 

Existing Facilities: Operations & Housekeeping Procedures

Often it is not the design, but the lack of consistent maintenance in existing facilities that pose risk. When conducting a DHA, the difference between the Maybe a hazard and Deflagration hazard categories is frequently proper maintenance and scheduled inspections of the equipment and associated safety features. To effectively manage hazards in a facility, DHA inspections will look for the following safety practices:

 

  1. Set schedules for cleaning and maintenance
  2. Cleaning thoroughness
  3. Lock out / tag out procedure for equipment cleaning
  4. Vacuuming for dust removal
  5. Pressure relief ventilation

New Facilities or Expansions: Considerations for Owners
Part of the NFPA 652 - Annex B states the “purpose of a DHA is to identify hazards in the process and document how those hazards are being managed.” For new construction, earlier is best for making hazard management design decisions. Recognizing and addressing dust hazards in the preliminary design phase of a project can lead to cost and time savings. Including features in the initial facility design like appropriate ventilation and use of a vacuum system for dust removal will reduce the need for future retrofits. Keep maintenance and hazard management integrated in a project by considering the following questions in early phases:

  1. What dust hazard codes, standards or guidelines must be met in the facility design?
  2. How are potential hazards managed within the process?
  3. What maintenance and/or housekeeping programs will be needed for safe facility operation?

NFPA 652 Article Image_Part I.jpg

This three-part series defines the NFPA 652 guideline changes and impact to existing and new facilities. The article will also explore compelling reasons to get ahead of this regulation change.

According to the National Fire Protection Association (NFPA), 50 combustible dust accidents occurred in the United States alone between 2008 and 2012. To continue improving and reducing hazard risk in agricultural facilities, the NFPA reviews and updates their guidelines every three years. The latest, 2016 edition of NFPA 652 Standards for Combustible Dust introduces the use of a Dust Hazard Analysis (DHA). This edition’s NFPA 652 update impacts existing and new facilities that combat dust-related hazards as a result of their processes. The NFPA now advises commissioning a DHA once every five years.

What Is a Dust Hazard Analysis?

A Dust Hazard Analysis (DHA) documents potential fire, flash fire and explosion (or dust deflagration) hazards. All potential hazards are placed in one of three general categories: Not a hazard, Maybe a hazard or Deflagration hazard. In existing facilities, a licensed professional will conduct a site visit to observe the process, categorize potential hazards and provide any recommended administrative or engineering safeguards to reduce the risk of deflagration. For new facilities or facility expansions, a licensed professional can assess and incorporate safety measures in designs based on the local jurisdiction and building codes.

When considering commissioning a DHA, reach out to the Authority Having Jurisdiction and a licensed professional. These entities will confirm which codes and guidelines are used in the jurisdiction and if a DHA is required for a project. To perform the DHA and offer practical solutions, engage a licensed professional that specializes in the industry, such as an architect, mechanical engineer or fire protection engineer. A qualified professional will be knowledgeable about the facility process and have a thorough understanding of local and state codes.

2018 Walk for Animals_LinkedIn.jpg

Cats, dogs, goats... Oh my! VAA employees raised funds and participated with their canine companions in the Walk for Animals, the nation’s largest human / animal walk fundraising event. Thousands of people, pets and other four-legged friends took part in this Animal Humane Society fundraising event in an effort to provide food, shelter, medical care and happy homes for a variety of animals.

On top of walking the walk, VAA employees donated over $1,600 to the cause. The 2018 Walk for Animals event raised 93% of its goal or over $900,000 to help many animals in need in our community.
