ESD SHOES, HEEL & TOE STRAPS are effective methods of GROUNDING operators when mobility is an issue, but, only if used in conjunction with flooring that can be bonded to ground. (i.e. matting, tiles, resin, coatings etc.).
When wearing HEEL or TOE STRAPS, there should be A STRAP ON EACH FOOT in order to ensure the best possible contact to GROUND when walking or standing. Whether the “earthing ribbon” fits under your foot or inside your sock doesn’t really matter, as long as the contact is a good and reliable one. When SITTING, WRIST STRAPS MUST ALSO BE WORN.
TESTING IS VERY IMPORTANT BECAUSE:-
| A) | 0.75 meg-ohm is checking that you don’t have a short circuit to ground. It has been calculated that 0.75meg-ohm will offer protection against 250v a.c. or 500v d.c. |
| B) | 35 meg-ohm ensures that you are not too resistive to ground. |
IF YOU FAIL A TEST, DON’T TRY AND FIDDLE IT, FIND OUT WHAT’S WRONG e.g. DAMAGED? DIRTY? DRY SKIN? NO RESISTOR?
CHEATING THE TEST IS CHEATING ON YOUR RESPONSIBILITY!!!
