Where glass or brittle material is used in production or storage areas for anything other than making the packaging itself, there are periodic inspection requirements and a defined breakage procedure, and glass and brittle items such as hard plastic parts and sight glasses are avoided where relevant and possible. Product-contact surfaces in production and storage are free of splinters and other contamination sources and easy to clean effectively. A formal sharps procedure applies: no sharp objects or loose tools are left where product could be contaminated, and snap-off blade knives are forbidden. Buildings, facilities and equipment are cleaned of dust, cobwebs, flakes and fragments to keep housekeeping acceptable.
