The Fire Sprinkler Scope of work consists of adding fire protection to a new 684 Sqft freezer and 1491 Sqft cooler. The storage commodity in the freezer is a variety of frozen meats, breads and deserts. The commodity classification is Class I-III depending upon the packaging. The storage commodity in the produce cooler is a variety of vegetables. The commodity classification is Class I.
