SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

  • Rotor Balancing: Ensure the rotor is balanced by loading tubes of equal weight symmetrically; imbalance may cause excessive vibration .
  • Lid Security: Verify the lid is securely locked before operation; the door interlock prevents operation with an open lid.
  • Tube Compatibility: Use only tubes certified for low-speed centrifugation (max 5,000 rpm) and meeting quality standards (e.g., conical bottom, high-strength plastic).
  • Rotor Loading: Load tubes in opposing positions; never run the rotor with a single tube or unbalanced loads.
  • Cleaning: Clean spills immediately and disinfect the rotor chamber if biological materials are involved.
  • Placement: Place the centrifuge on a stable, level surface; ensure adequate airflow around the instrument.
  • Training: Only trained laboratory personnel should operate the centrifuge.

2. FIRST AID MEASURES

  • Tube Breakage: If a tube breaks during operation, stop the centrifuge immediately, allow the rotor to stop fully, carefully remove fragments using forceps, and disinfect the rotor and chamber.
  • Sample Splash: If a biological sample splashes, disinfect the area immediately with an appropriate disinfectant (e.g., 70% ethanol, bleach solution).
  • Imbalance Shutdown: If an imbalance shutdown occurs, rebalance the rotor equally and restart the centrifuge.

3. FIRE FIGHTING MEASURES

  • Flammability: Plastic and electronic components may burn.
  • Extinguishing Media: Use carbon dioxide (CO₂) or dry chemical extinguisher for electrical fires.
  • Fire Response: Unplug the centrifuge immediately; do not use water on electrical fires.
