The question asks about steps to take in the event of glassware breakages and has multiple blanks to fill. 
First, we consider whom to inform when glassware breaks: options are typically roles in the lab. The correct action is to notify the Lab Demonstrator, since they oversee safety and know the proper cleanup protocol. 
Option: Lab Demonstrator — this is the appropriate person to inform to ensure safety procedures are followed and proper guidance is given. 
Option: Lab Supervisor — while a supervisor might be appropriate in some contexts, the provided material prioritizes the Lab Demonstrator as the contact for breakages, so this option would be less correct in this specific scenario. 
Option: Teaching Assistant — TAs may assist, but the standard immediate notification is usually to the Lab Demonstrator who is directly responsible for the lab setup and safety. 
Option: Manager — in a teaching lab setting, a manager may not be the designated first contact for breakages.

Moving to the collection method for broken glassware: the safe and common practice is to avoid using bare hands and to use a dustpan and brush to scoop up shards. Using hands risks cuts, and using paper towels alone can leave fragments or create additional hazards. Leaving it for someone else to clean up is irresponsible and unsafe. A vacuum cleaner is generally not used for broken glass on bench surfaces due to the risk of the shards damaging the vacuum or being thrown around; some vacuums are not appropriate for glass cleanup. 
Option: With your hands — incorrect due to risk of cuts and contamination. 
Option: With your lab notebook — not a cleanup method; it wastes time and provides no safety benefit. 
Option: Leave it for someone else to clean up — incorrect; safety responsibility lies with the person who broke the glass or the designated safety responder. 
Option: Using paper towel — not ideal as a sole method; it can leave splinters and may not contain shards effectively. 
Option: Using a dustpan and brush — correct; provides controlled pickup of shards and reduces injury. 
Option: Using a vacuum cleaner — often discouraged or restricted for broken glass on work surfaces due to risk of scattering shards or damaging equipment.

Finally, where to dispose of clean broken glassware: the proper disposal is in a designated broken glass bin if one is provided; general rubbish or recycling bins are not appropriate for broken glass due to injury and contamination concerns. In some facilities, there is a specific “broken glass” bin or sharps container, but not a general rubbish bin. Putting glass back in a cupboard or down the sink is not appropriate. 
Option: General rubbish bin — typically incorrect because glass shards can injure others and are not accepted in general waste streams. 
Option: Broken glass bin — correct; designed to securely hold broken glass to prevent injury. 
Option: Recycling bin — only if the glass is unbroken and correctly sorted; generally broken glass goes to the broken glass bin, not recycling. 
Option: In the sink — incorrect due to hazard and potential clogging or injury. 
Option: In a waste carboy — unlikely and unsafe; not the standard disposal method in most teaching labs. 
Option: Put it back in the cupboard — incorrect; this would store broken glass rather than safely disposing of it.

In summary, the intended answers align with notifying the Lab Demonstrator, collecting with a dustpan and brush, and disposing in the broken glass bin, with all other options being unsafe or inappropriate in typical laboratory safety protocols.
