A WRIST STRAP is the most effective method of BONDING an operator to GROUND when mobility is not an issue. It DISCHARGES the “STATIC” being generated on the BODY to ground “instantly”.
Wrist Straps must be WORN while SITTING, even when “E.S.D” footwear is being used.
Straps should be CLEAN, SNUG and COMFORTABLE. If your strap is LOOSE and/or DIRTY, you run the risk of having an INTERMITTANT CONTACT to ground.
Coil cords should have a 1MEG-OHM safety resistor in the “SNAP” that ATTACHES TO THE WRIST STRAP. The strain relief should be intact and the coil tight so that it doesn’t hang and catch too easily.
The OUTER SURFACE of the WRIST STRAP should be INSULATIVE for operator safety.
TESTING IS VERY IMPORTANT BECAUSE:-
| A) | 0.75 meg-ohm is checking that you don’t have a short circuit to ground, which could be dangerous. It has been calculated that 0.75 meg-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!!!
ALWAYS WEAR YOUR WRIST STRAP!!!
