• Neutralization of Waste: HF waste should be neutralized before disposal.
• Proper Labeling: All HF waste containers must be clearly labeled to prevent accidental exposure or mishandling.

1.6. Emergency Preparedness:

• First Aid: Personnel involved in HF handling should be trained in administering first aid for HF exposure.
• Emergency Equipment: Adequate emergency equipment, such as eye wash stations, safety showers, and spill containment kits, must be available and readily accessible.

1.7. Training and Documentation:

• Training: Thorough training programs for all personnel handling HF are essential. Training should cover topics such as hazard identification, safe handling procedures, emergency response, and first aid.
