Course description

In Explosion in New Jersey: How a Small Amount of Water Proved Deadly , you'll learn ...

  • How a relatively small volume of water intrusion in a blending process contributed to an explosion that killed five (5) people
  • Why the blending equipment used was inappropriate for the process conditions
  • The efforts by workers to control the situation that ultimately proved unsuccessful and directly contributed to the loss of life
  • Lessons learned from the accident that can be applied to chemical processing facilities, as well as other industries


To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 150 minutes has been met.

Water is vital to life, but it can also be deadly. On April 21, 1995, a small amount of water was the catalyst for a violent explosion and fire at the Napp Technologies, Inc. specialty chemical plant in Lodi, New Jersey. The blast killed five (5) and injured four (4) workers at the plant.

At the time of the explosion and fire, Napp was conducting a blending operation. The fact that water-reactive chemicals were used in the process was well understood by workers and management. Although Napp took steps to eliminate or control sources of water, the company elected to use blending equipment that incorporated sources of water in the design.

While performing the mixing operation on April 21, 1995 to produce a gold precipitating agent, a small amount of water entered the blender. The resulting exothermic reaction started a chain reaction of events, culminating with the explosion and fire that killed five (5) people.

In this course, we’ll review the events surrounding the incident at the Lodi, New Jersey plant. You’ll learn about the factors that contributed to the accident, as well as steps you can take to prevent similar occurrences in the future.
