Isolate and Depressurize. The first step when preparing for maintenance on any fluid system is depressurization. When doing so, a best practice is to have two block valves in sequence to guard against pressure buildup in the section of the line under maintenance. A good valve should not leak across the seat, but this could happen.

In 1953, William James Scott showed that microbial growth in food is governed not by water content, as most people thought, but by water activity. Four years later, he established the concept of a minimum water activity for microbial growth. Water activity is now routinely used by food manufacturers to
