Martha, The glass register must be as detailed as it needs to be. And unfortunately this is another thing that is very subjective. You may argue you don’t need to include a glass that is far away from production, but any given auditor can think different.
My advice is to do it based on RISK. What are the probabilities of the item to break? and if it breaks, what are probabilities of reaching the product?. I think you must include as many items as necessary but you cannot include them all as the list would be so extensive and a waste of time. That is one of the purposes of risk assessment, to allocate the resources (in this case the time of an employee to check every single brittle object in the plant) to where there is more chances of risk reduction.
Additionally, you could also add RISK AREAS. For instance everything that is on or immediate to the production area or equipment is high risk, and needs to be checked more frequently (daily pre-operational). MEDIUM RISK for items that are adjacent to the area with lower risk of brokerage or contamination (such as the extinguisher gauge in the wall 50ft away from the packing line).. This could be inspected at a lower frequency, such as Weekly or Monthly?.. And LOW RISK for items that are far away (office windows and lights, etc.) and those could have a different schedule such as Monty or Quarterly?
Here is an example of what you could do for a glass/brittle risk assessment. Based on that then you can create your glass registers.
NOTE: You can format this in a chart.. but I was not able to create or paste a chat in here.
Item: Packing Line Fluorescent light
Probability of Breaking: HIGH: People and machine activity nearby, within reach of people and machines. Very fragile glass.
Probability of Contamination: HIGH: Bulbs are protected with sleeves, but are located right above product
Area: HIGH RISK AREA
Risk (High, Medium, Low, Very Low): HIGH
Inspection Frequency (Daily, Weekly, Monthly, Quarterly, NOT INCLUDE): Daily
Finally, don’t sort the items in your glass registers alphabetically, but by location. An easy way and idea is to make a facility plan (such as the pest control map/plan) with the items and use that to check them, or organize the list in the order you will find the object in your walking route.
Just ideas to make your operation more efficient while keeping it safe.
