However, as the velocity of penetrating projectile decreases, the irregularities of shape of hole, and its surrounding cracks increases so at that point the hole shape may not determine the direction of impact. 7.2.2. Continued movement of the glass will cause extensions to the original fracture, usually in a straight line. The Hazard Analysis and Critical Control Point (HACCP) program mandates that food processors determine potential biological, chemical and physical hazards that are "significant" or "reasonably likely to occur" and establish programs to eliminate those hazards or reduce it to an acceptable level.
