Dust Explosion Characterization and Hazard Assessment (Part 2)


Methods have been presented to

evaluate the dust and hybrid explosion

hazards in plants and process operations.

Ways to evaluate hazards have been

presented relative to material reactivity,

ignitability and explosion output. Criteria

for successful engineering hazards analysis

have been identified. In powder operations,

dust and hybrid fires and explosions can be

minimized so that the potential is never

near the operational… Continue

Protect Your Workers from Heat Related Illness and Death.

These incidents remind us to provide employees with the proper training to ensure their safety when working in these conditions.

Citation or Accommodation?

By now most all of us are aware of the act of heroism by construction worker Jason Oglesbee as he plucked a woman out of the Des Moines River saving her from almost certain death. Many of my colleagues as well as I have been challenged philosophically about this event. Without regard for his own safety Mr. Oglesbee crawled into a set of grade 80 rigging chains and had the crane operator lower him into the water to save the women. I am sure you are aware the outcome was all good. However, it… Continue

Hay Exporter Reaches Last Straw with Dust Issues and Worker Discomfort

As an exporter of timothy hay and alfalfa to the Far East, Ward Rugh, Inc. in Ellensburg, WA generated much fugitive dust in their operation as they compacted bales for shipment. Expansion to the operation contributed to the housekeeping challenge and the increased processing of hay, a common allergen, contributed to worker discomfort.

Hay dust presents challenges for dust collection similar to many fibrous dust types. It's lightweight and consists of a wide range of strand… Continue

The Near Miss I Never Saw

Anyone who has spent any time in the field hears someone ask why we use the term "near-miss". After all, wasn't it more of a "near-hit" or even a "total miss"?

All joking aside, we know that these events, whatever we call them, are both an indicator of problems and an opportunity to improve the overall safety of our facilities.

A near-miss, in my experience, is an event that happened, and just by chance it did not result in a serious outcome. When someone runs a red light as the cross… Continue

Safe Behavior for Supervisors

Hello, Safety Community! I'm looking for a video on Safe Behavior that I could present to a supervisory meeting to be held next week. I'm trying to promote a Safe Behavior Program for this government entity. If anyone out there has a video clip, DVD, or PPT Prorgram covering this topic would be helpful. I'm really trying to sell the benefits of this type of program to this group of supervisors.

Vitamin Manufacturer Takes Double Dose of Dust Collectors and Safety Precautions

Some would say that two identical dust collection systems on a single, centralized vacuum system is redundant, redundant. One vitamin manufacturer who wanted non-stop dust collection on a '24/7' basis would agree! But he'll also tell you that he replaced 10 small dust collectors of different types that were scattered throughout his manufacturing plant, resulting in filter inventory, maintenance and dust disposal that were time consuming and… Continue

With the H1N1 flu the CDC, WHO and OSHA are providing information for employees under the "general duty clause" to protect their employees from the H1N1 flu by using the N95 respirators and additional PPE. The N95 respirators do require fit testing and training. 3M has a large backorder shortage of N95 respirators because health care facilities are stock piling the respirators. If you would like you can go to or or and see what is being required for the protection of 13… Continue

This is NOT Your Safety Manager - Conclusion

Last week I wrote this post about a time I hired a safety professional and insisted that he not be called a safety manager. The reason why, the post explains, is that we wanted employees to take full accountability for their own safety.

That frame of mind served us well as an organization. The safety professional was truly an expert, and his expertise was critical in making sure we didn't… Continue

Dust Collection for Hazardous Rubber Grinding

Common rubber grinding dust generating processes include tire manufacturing, retreading and recycling as well as the production and recycling of appliance moldings, rubber gloves and various automotive parts. Rubber dusts in these types of applications pose challenges for industrial dust collection systems as well as potential health hazards for workers.

Oils in rubber are the biggest problem for dust collectors. In… Continue

Case Study: Nuisance Limestone Dust Cleaned Up for Employees

Got quarry dust? Then read on. Indiana Limestone Co., Inc. (ILCI) of Bedford, IN, needed to find a way to clean up massive amounts of dust generated in its limestone cutter's bay. Though limestone dust is completely non-toxic - being classified by OSHA as a nuisance dust - the word "nuisance" describes it well. The fine powdery material hinders visibility in the work area, permeates sensitive tools and machinery, and creates continual cleaning… Continue

Explosion Protection and Dust Collectors for the Paper Scrap Industry
