Did OSHA ask enough pertinent questions in the Combustible Dust ANPRM proposed rulemaking?

We are having discussions about the proposed combustible dust rulemaking on the Linkedin site, Combustible Dust discussion group, and would appreciate any comments or suggestions, or insight into your experience with OSHA related to combustible dust.  Go here to participate:

Probabilty of Occurence...A Global View

A good point is made by John Astad, ComDust Policy Institute.  To properly identify process safety concerns and areas of improvement, first we must understand probability of occurrence, second severity.  We can then create a matrix of probability and severity to address the highest priority processes.

OSHA Compliance: How to Ensure that Your Efforts Are on Target

OSHA compliance should be on every stakeholders mind, as should safety in general.  Continuous improvement is key.  Do you see OSHA compliance as a concern, a pain in the butt, or as part of keeping your plant and workers safe?   Your comments are welcome and appreciated.

What is a ComDust Hazard?

Different sources report that 70 - 80% of process dust and fines are combustible, depending on the process and material variables.  Keys are understanding your process hazards, the combustibility of your material and fines.  But remember, processes are not static. Processes and materials change over time.  Education, hazard awareness, testing, training, process design, controls, maintenance, housekeeping, policies and procedures are keys to long term process safety.

Inferno: Dust Explosion at Imperial Sugar

YouTube - Inferno: Dust Explosion at Imperial Sugar
Shared via AddThis


This is a very instructive video and case study from the US Chemical Safety Board entitled: Inferno - Dust Explosion at Imperial Sugar.  While this video pertains to sugar dust, it applies to most any combustible dust application.  The Imperial Sugar plant used many of the same processes and machinery used in many process industries, such as grinding and milling, belt and screw conveyors, bucket elevators, dust collectors and storage silo's.   

This video explains in detail how process, conveying, dust collection, housekeeping and safety system design, or lack of, all impacted the fires and explosions in this process - that killed 14 workers, injured dozens of others, and shut the plant down for an extended period of time.  This tragedy exposes the critical need in our process industries for inherently safe design along with housekeeping, proper safety systems design and training.

Also, this ca…
