How do I determine my glove size?

To determine your glove size, measure the circumference of your hand at the palm.  Wrap a string around your palm.  Measure the length of the string in inches.  This is your glove size.  Allow for additional room if you wear fabric glove liners.  1/2 size should do.

What does Hazard Risk Category mean?  I hear level 1, level 2 and level 4 arc flash suits a lot.

Hazard Risk Category is the level of arc flash protection clothing you must wear to protect against a minimum level of incident energy measured in calories per centimeter sqared.  Meaning, electrical equipment, depending upon the energy delivering capability, under fault conditions can cause an explosion, or arc fault of a certain level, again measured in calories per centimeter squared.  That explosion can deliver a certain amount of heat to a certain distance.  Each level, 0-4, is rated at a certain amount of flame resistance, again measured in cal/cm2.  Each level is considered a category.   Page 35 of NFPA 70E 2009 edition list the details of each category.  Also see the NFPA 70e manual table 130.7 (c)(9), Page 30 - 34.  To beter understand the details, you must take arc flash or NFPA 70E training,  One paragraph can not substitute for 8 hours of training.
