Do you have both feet on the ground? If you’re wearing 1-meg heel grounders, you may not be as grounded as you think.
UL and OSHA recommend a minimum of 1 megohm resistance to ground (RTG) to ensure the flowing current will be within safe levels. With both feet on the ground, your 1-meg heel grounders yield an RTG of ½ megohm, not 1 megohm.
How can you be UL and OSHA compliant at all times? Consider the following chart:
| 1-Meg Heel Grounder(s) | 2-Meg Heel Grounder(s) | |
| 1 Foot on the Floor | RTG = 1 | RTG = 2 |
| 2 Feet on the Floor | RTG = 1/2 | RTG = 1 |
All-Spec carries an assortment of heel grounders for complete path-to-ground protection. While the size of the built-in resistor depends on the standards of your specific operation, wearing two, 2-meg heel grounders means you’ll be sufficiently protected—and well-grounded—no matter what.
