Static dissipative (SD) footwear is designed to safely control the buildup of static electricity on the body by providing a controlled path for static discharge to the ground. This prevents hazardous sparks that could ignite flammable materials or damage sensitive electronic equipment. The footwear is categorized into three resistance levels (SD 100, SD 35, and SD 10) to suit different workplace safety requirements, ensuring protection in environments where static electricity poses a risk.
Key Points Explained:
-
Primary Purpose of SD Footwear
- SD footwear prevents dangerous static discharges by channeling electricity safely to the ground.
- This is critical in industries like chemical manufacturing, electronics assembly, and oil & gas, where static sparks could trigger fires, explosions, or equipment damage.
- Unlike insulating footwear, which blocks electricity entirely, SD footwear allows a controlled flow to dissipate charge gradually.
-
How Static Dissipative Footwear Works
- The soles are engineered with materials (e.g., carbon fibers or conductive rubber) that offer specific electrical resistance.
- Resistance is measured in megohms (MΩ), with lower values allowing faster dissipation. For example:
- SD 100: ≤100 MΩ (general industrial use)
- SD 35: ≤35 MΩ (higher-risk areas like munitions handling)
- SD 10: ≤10 MΩ (ultra-sensitive environments like cleanrooms).
-
Key Applications
- Explosive Atmospheres: Prevents static sparks near flammable vapors or dust.
- Electronics Manufacturing: Protects microchips from electrostatic discharge (ESD) damage.
- Healthcare/Pharmaceuticals: Safeguards sterile environments where static could attract contaminants.
-
Selection Criteria
- Match resistance level to workplace hazards (e.g., SD 10 for labs with volatile solvents).
- Ensure compatibility with grounded flooring (e.g., conductive epoxy floors).
- Verify compliance with standards like ASTM F2413 or EN 61340.
-
Maintenance & Safety Notes
- Regularly test resistance with a megohmmeter to ensure functionality.
- Avoid wearing SD shoes in wet conditions unless rated for it, as moisture can alter resistance.
- Pair with anti-static clothing for full-body protection in high-risk zones.
By understanding these factors, purchasers can select SD footwear that balances safety, comfort, and regulatory compliance for their specific operational needs.
