There are numerous instances when a glass can fail and a glazing film is capable of containing any resulting damage. Toughened glass is known for explosive failures without any apparent reason. The reason for such failures have been pointed to the presence of contaminants like nickel sulfide which get into the glass during the manufacturing process. Accidental breakages of float glass can result in sharp shards of flying glass. These flying shards of glass can cause injury to people who are within the vicinity of the damaged glass. Breakages of glass also happen in the event of earthquakes. When the ground gets shaken due to seismic activity, building experience movement, and these movements cause glass breakage.
The flying shards of glass from the broken windows, etc. can cause injury to people within the building and also to others below the building, etc. Bomb blast explosions cause widespread damages and the intensity of damage is increased due to the flying shards of glass, and flying shards of glass cause the most damage. When a glazing film is applied to glass it prevents the glass from shattering and thus nullifies the damages that flying shards of glass can cause. Glazing films are really helpful!
