13) RECOMMENDED STORAGE CONDITIONS:
Dry, not humid. Out of the sun, preferably in a cool, shaded and well ventilated area. Once package is opened, consume within reasonable time. Store opened and unused packages after adequate re -sealing to avoid contamination and moisture ingress.

14) PERSONNEL SAFETY:
Non-toxic, but avoid inhalation, ingestion. Wear suitable protective gear. If “slimy” feel in mouth due to inhalation/ingestion, drink plenty of water.

15) SPILLAGE REMOVAL (DRY):
Vacuum off. Avoid sweeping, as could lead to excessive dusting. Ensure increased ventilation, if dusting should occur.

16) SPILLAGE REMOVAL (WET):
Use sawdust or other absorbent. CAUTION! Wet spillage is extremely slippery. Remove and dispose only after relatively dry. Spray with suitable disinfectant, wet spillage could lead to microbial growth, if left to stand for long periods.
