Cleaning up broken glass should be done immediately as it poses a danger to those nearby. However, it must be done carefully to ensure safety and cleanliness. Follow these steps:

1. Clear the Area of People
   When there is broken glass, make sure to remove people from the vicinity. This helps ensure a thorough cleanup and reduces the risk of harm to others.
   
   
2. Use Bright Lighting
   Use the brightest lighting available to make it easier to spot and clean up glass shards.
   
   
3. Pick Up Large Pieces First
   Collect large shards of glass using gloves or tongs to avoid injuries. Wrap the pieces in thick paper or cardboard before disposing of them.
   
   
4. Clean Up Smaller Glass Shards
   Clean up the remaining small shards using tools like a broom, bread or potato slices, wet tissues, a lint roller, or adhesive tape.
   
   
5. Perform a Final Cleanup
   Remove any glass particles stuck to the cleaning tools by rinsing them off or using adhesive tape to pick up the shards.
