Just to add some generic, high-level advice to the (far more useful) information provided above.
The Glass Policy and associated procedures should be taken very seriously in a food manufacturing environment. It shouldn't be just considered a documentation exercise - the effectiveness of a glass policy is not in the measures described but in the efforts and focus to control and monitor glass usage in the production environment.
To give an example, our company has a long-standing glass policy & breakages procedure which was updated relatively recently. However, without us really noticing, an element of complacency had creeped in. We recently experienced (suffered?) an audit with a major customer, where a glass breakage occurred on a line with the auditors present. Our response to this incident did not fill them with confidence to put it mildly...
Don't forget regular audits of the facility to check that all items on the glass/brittle plastic/ceramics register are in place and unbroken. Monthy intervals have been strongly recommended, and preferably done by your company's Food Safety Committee.
A daily Pre-Operation checkist (performed at the beginning of each shift if possible) also strenthens your committment to your glass/brittle plastics/ceramics policy.
