Learn From History: Analysis of West, Texas Fertilizer Explosion

Industrial accidents range in severity and impact from minuscule to catastrophic. As operators, owners, or technicians involved with industrial operations, we all have a degree of moral, ethical, and legal responsibility to conduct our work in a manner that does not unduly endanger personnel, property, or the environment. Maintaining a diligent safety stance can be helped by reviewing industrial accidents at other facilities. There is much to learn from these unfortunate events, even when they happen in an industry that may seem somewhat removed from your own.

The U.S. Chemical Safety Board, or CSB, is an independent federal agency that investigates industrial chemical accidents. Below, find one of their video reenactments of an explosion that occurred in Texas in 2013, along with their findings regarding the cause of the incident. Check out the video and sharpen your senses to evaluate potential trouble spots in your own operation.

Easy Pressure Switch Installation for Hazardous Areas

Industrial process control applications present an unending stream of challenges to designers, engineers, technicians, and other stakeholders. Because of the general nature and scale of industrial operations, there is often danger and risk involved during normal operation, as well as the potential for catastrophic impact to personnel, environment, and other assets in the the case of failure. The equipment and components we employ in our processes have three areas of consideration. Firstly, they must perform some range of functions reliably under normal operating conditions. Second, the contribution of any device to the risk of process failure must be minimized. Thirdly, there may be performance requirements for the device under abnormal process or environmental conditions.

Hazardous areas, with potentially explosive atmospheres due to the presence of certain gases or fine particulates, pose a particularly challenging set of circumstances to those of us striving to make things work properly. Everything within the hazardous area must be hardened in such a way that it poses no risk of being the source of ignition of the surrounding atmosphere. There are various effective methods for accomplishing this, most of which involve substantially increased cost and time.

Custom Control Sensors, a manufacturer that devotes a substantial portion of its product line to control devices for use in hazardous areas, has added a new development to their series of adjustable setpoint industrial pressure switches. The latest addition to the line is suitable for hazardous areas and has a unique feature that will save time, money, and a even a little space in your process area.

The newest version of the company's 6900 series industrial pressure switch features a Turck® connector that simplifies installation in Class I, Division 2 applications. Use of the connector eliminates the need for an electrical junction box at the sensor location and makes installation or removal of the device a simple operation. This improvement simplifies the deployment of pressure switches in hazardous areas.

The features and specifications for the product are included in the data sheet that I have shared below. The manufacturer sees applications for the product in:

  • Wellhead control panels
  • Chemical injection skids
  • Hydraulic control packages
  • Gas compression skids
  • Off-shore and on-shore installations
You may have your own potentially advantageous applications for this or some other CCS products. Contact a product specialist to explore product solutions to your process challenges.

Description of a Process Control Enclosure in a Hazardous, or Explosion Proof Location

This is a short video that explains what an explosion-proof enclosure looks like, how it works, and why it is safe to use in explosive or combustible atmospheres.

The definition of "explosion-proof" doesn't mean the enclosure can withstand the forces of an external explosion, but rather that it will cool any escaping hot gases (caused by an internal spark or arcing contacts) sufficiently enough as to not to allow the ignition of combustible gases or dusts in the surrounding area.
