The static charge of the human body can be safely released to the anti-static floor through the conductive straps in contact with the skin, and then released to the ground through the grounding system of the floor, which is one of the anti-static measures of the human body. 

The ESD heel strap has no limit on the ground cable. It is suitable for workers with high mobility. 

Note: 

1. When using an ESD heel strap, each user should wear two feet at the same time to increase the contact time and continuity between the heel strap and the ground and reduce the possibility of electrostatic damage to the human body. 

2. The conductive ribbon must be in good contact with human skin. 

3. Use the device on an ESD floor or ground where the system is grounded. 

4. Fasten the ESD heel strap to ensure the ESD effect and safety. 

5. Clean regularly and keep clean.
