A major change is coming to the National Fire Protection Association (NFPA) standards regarding combustible dusts. Many of you have utilized the NFPA standards in the past. The combustible dust standards are in place to provide guidance on ways to identify materials that may pose fire and explosion hazards, determine where and when these hazards might occur, identify and review safeguards needed to prevent injury to personnel and damage to equipment and property, and to track the progress for improving these safeguards.

By now most companies and people throughout the manufacturing sector have heard of Combustible Dust as it has become a widely discussed topic. As a review, combustible dust fires and explosions are caused when a combustible atmosphere of dust, or a layer of flammable solids, is introduce to an ignition source. This can be demonstrated by the fire triangle or explosion pentagon. These ignitions can be made worse if there are significant levels of dust accumulation present in surrounding areas, and hazard mitigation techniques are not properly utilized. One of the best ways to identify these dust fire and explosion hazards, as well as being the first step in putting a mitigation action plan together is a Combustible Dust Hazard Analysis (DHA). Besides being a great first step it is also a required one according to the National Fire Protection Association (NFPA) standards 652 and 61.

Many facilities in the food and agriculture industry have processes that handle combustible dusts and powders. Because of this, the National Fire Protection Association (NFPA) has developed several standards to help facilities have safely manage combustible dust and associated hazards. Many of these standards are commodity-specific standards that are developed to give specific industries combustible dust standards that are based on their types of operation equipment, and the input from those that know the most about those processes and materials. Facilities in the food and agriculture industry should refer to NFPA 61: Standard for Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities which was recently updated in 2020. One primary requirement listed in NFPA 61 is the need for facilities to conduct a Dust Hazard Analysis (DHA) by January 1, 2022.

What is a DHA? Continue reading “NFPA 61 Dust Hazard Analysis (DHA) Deadline Is Approaching”

An increasing number of facilities that handle combustible dusts have conducted a Dust Hazard Analysis (DHA). A DHA, in summary, is an evaluation of the fire, deflagration, and explosion hazards present at a facility due to the handling, generating, and otherwise production of combustible particulates. The National Fire Protection Association (NFPA) requires that all facilities handling and/or generating combustible dusts have a DHA completed by September 7, 2020 (NFPA 652 Chapter 7.1.1.2). The deadline for food and agricultural facilities to conduct a DHA is January 1, 2022 (NFPA 61 Chapter 7.1.2.2). Continue reading “DHA Revalidation. I’ve done my DHA. Am I done?”

Most facilities that are handling combustible dusts are now familiar with the term “Dust Hazard Analysis” or “DHA” and understand that it comes from a standard issued by the National Fire Protection Association (NFPA), nfpa.org. The most referred to standard is NFPA 652 – Standard on the Fundamentals of Combustible Dust. From NFPA 652, the key requirements for conducting a DHA are: Continue reading “Combustible Dust Hazard Identification and the Dust Hazard Analysis (DHA)”

Most facilities that are handling/producing combustible dusts are now familiar with the term “Dust Hazard Analysis” or “DHA” and understand that it comes from a standard issued by the National Fire Protection Association (NFPA), nfpa.org. Furthermore, by now, many facilities subject to the requirements for conducting a DHA on their existing processes have had that completed. The most referred to standard is NFPA 652 – Standard on the Fundamentals of Combustible Dust. This set the requirement to have the DHA completed for existing processes by September 7, 2020. Now the commodity specific standard for agricultural and food: NFPA 61 – Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities did set a different date of January 1, 2022. This is the only commodity specific standard that did this; all other standards refer to the date in NFPA 652. There are a few other differences around the DHA requirements between NFPA 61 and 652. For the purposes of this article, we will just focus on the requirements in NFPA 652. Continue reading “Dust Hazard Analyses (DHAs) for New and Modified Processes”

After a difficult year amidst a global pandemic in 2020, we can finally look ahead to a hopefully brighter 2021. A new year always brings changes to health and safety regulations and requirements. On January 19, 2021, James Frederick was appointed as the Deputy Assistant Secretary of Labor for Occupational Safety and Health, and will be the acting administrator for the Occupational Safety and Health Administration (OSHA) until a new Director is determined.

One of OSHA’s primary concerns at the start of 2021 has been employee safety relating to COVID-19. Since the start of the pandemic, OSHA has issued citations with penalties totaling $3,930,381. Common violations found from these inspections include failures to perform the following: Continue reading “What to Expect From OSHA in 2021”

When we are discussing whether a facility needs to conduct a Combustible Dust Hazard Analysis (DHA) or if dust explosibility testing is needed, it is common for material like aluminum dust, phenolic resin, iron, powder coat, etc. to be included in the discussion as it is relatively known that these materials are combustible dusts. However, it regularly occurs that the dusts and fumes from welding activities are not brought up by the facility. A widely held view in general industry is that dust from welding operations contains only oxidized metal and is therefore not combustible. Recent studies and CTI’s own investigations have found this to be incorrect.
