Key principles covered are JSA/JHA/AHA procedures to ascertain shock protection boundaries, arc flash incident energy expressed in calories/cm2, lockout-tagout, and personal protective equipment. While the various OSHA, ASTM, IEEE and NEC standard provide guidelines for performance, NFPA 70E addresses practices and is widely considered as the ...
a signal word – either Danger or Warning – where necessary hazard statements , indicating the nature and degree of the risks posed by the product precautionary statements , indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment)
IEEE 1584-2018 is an update to IEEE 1584-2002 and was developed to help protect people from arc-flash hazard dangers. The predicted arc current and incident energy are used in selecting appropriate overcurrent protective devices and personal protective equipment (generally abbreviated as PPE), as well as defining safe working distance. Since ...
ISO 7010 states on all symbols with a first aid cross, that it "may be replaced with another element appropriate to cultural requirements". In countries with a Muslim -majority population, an appropriate symbol is the crescent .
[citation needed] Higher voltages can cause a spark to jump, initiating an arc flash without the need for physical contact, and can sustain an arc across longer gaps. Most powerlines use voltages exceeding 1000 volts, and can be an arc-flash hazard to birds, squirrels, people, or equipment such as vehicles or ladders.

An example of a HMIS III label for Diesel fuel. The Hazardous Materials Identification System ( HMIS ) is a proprietary numerical hazard rating that incorporates the use of labels with color bars developed by the American Coatings Association as a compliance aid for the OSHA Hazard Communication (HazCom) Standard.
Generic warning symbol (Background color varies) On roadside warning signs, an exclamation mark is often used to draw attention to a generic warning of danger, hazards, and the unexpected. In Europe and elsewhere in the world (except North America and Australia), this type of sign is used if there are no more-specific signs to denote a ...
