Three key points from the document:
1. Two maintenance mechanics were fatally injured in a combustible dust flash fire caused by failure to follow lockout/tagout procedures when restarting a bucket elevator during maintenance. The elevator restarted, lofting iron dust into the air and igniting it.
2. Bucket elevators present risks of combustible dust fires and explosions if proper safety procedures are not followed during inspection, cleaning and maintenance when dust can be dispersed. Lockout/tagout procedures must address explosive atmosphere hazards.
3. Existing OSHA regulations do not have a specific combustible dust standard, relying instead on NFPA standards which do not provide clear guidance on identifying combustible dust fireFabrication Shop Ergonomics

Slavery as a cause of the civil warTeresa Long

Slavery was the central issue dividing the Northern and Southern United States and the primary cause of the Civil War. The Southern economy depended on slave labor for cotton production, while the North rejected slavery and embraced industrialization. Life for slaves was brutal, with frequent beatings, malnutrition, and lack of basic necessities even for children. Slave owners justified slavery through claims of black racial inferiority, despite slaves making up a large portion of the population. The divisions between the free North and slave-holding South grew too deep to be resolved through compromise, making war inevitable to decide the issue of slavery in America.Total War: An Unnecessary Evil?
Total War: An Unnecessary Evil?Teresa Long

General William T. Sherman's "Total War" campaign against the South during the U.S. Civil War involved burning cities, destroying infrastructure, and seizing or destroying Southern property and resources. This took a heavy toll on civilian populations, especially women left to care for their families. While Sherman believed this approach was necessary to break the Confederate spirit and force a surrender, Southern women like Mrs. Burgess and Mrs. Chesnut felt the suffering inflicted on innocent civilians was cruel and unnecessary. They maintained their resolve despite extreme hardship and poverty. The "Total War" strategy failed to achieve Sherman's goal of destroying morale, though it did help hasten the end of the war through economic devastation of the South.Ensuring a Safe Sustainable Future Water supply

Two maintenance workers were fatally injured while inspecting a bucket elevator that transported combustible iron dust at a manufacturing facility. When the workers requested the elevator be restarted without following lockout/tagout procedures to de-energize it first, combustible dust was dispersed into the air and ignited, engulfing the workers in a fireball. An investigation found the company failed to effectively communicate the explosive dust hazard, properly train workers, implement lockout/tagout procedures, and remove accumulated combustible dust. Regulations and standards need to explicitly address combustible dust explosion hazards during maintenance of equipment like bucket elevators to prevent similar tragic accidents.Workplace Security-Suspicious Package Protocol
