The Myths and Realities of Arc Flash Protection
Electric Energy Online has an excellent article that is mostly about Personal Protective Equipment (PPE) used for arc flash protection. It discusses 10 myths about arc flash.MYTH 1: Arc Flash explosions do not happen… I have never seen one.
MYTH 2: There is nothing anyone can do to protect against an Arc Flash explosion
MYTH 3: Will Street Clothes made of cotton or other natural fibers protective me?
MYTH 4: Spectacles and Sunglasses will protect me from the heat of an Arc Flash exposure
MYTH 5: I wear a face shield… that should be enough
MYTH 6: I wear a face shield… when would I need a hood?
MYTH 7: FR Clothing is all the same.
MYTH 8: ATPV = 100% Protection
MYTH 9: Aluminized clothing is an effective choice for protection from Arc Flash hazards.
MYTH 10: I am confused by the Table 3.3.9.3 in NFPA 70E. What exactly is a Hazard/Risk Category?
It is a good, practical real-word article that provides explanations demonstrating that all of the above are myths.

Thank you for this summary. I've worked with electricians who have no understanding of the danger. Busting these myths is something that needs to be done.
