CEP: Process Safety Beacon - Persistence – Good or Bad?

Process Safety Beacon
Some process safety incidents have occurred because operating personnel failed to recognize that a process was not responding as expected. They attempted to keep a process in operation by deviating from standard procedures, or put themselves in danger by attempting to correct an out-of-control process condition rather than evacuating.

CEP: Process Safety Beacon - Major Spills and Environmental Incidents

Process Safety Beacon
We may think of process safety incidents as fires, explosions, and immediate injuries from exposure to toxic, corrosive, or otherwise hazardous materials. However, major spills of hazardous materials, especially into rivers or other bodies of water, are also process safety incidents. They have the potential to impact large numbers of people, including people far away from your plant.

CEP: Spotlight on Safety - Normalization of Deviation — Identify It, Correct It, Prevent It

Spotlight on Safety
Louisa Nara
Whether we are talking about occupational safety or process safety, normalizing a deviation can result in unsafe practices, conditions, and operations. Getting comfortable with and accepting these deviations can cause a shift in our perception of what is safe. Why does this matter? Moving the target for safe operating limits and tolerating the higher risk s associated with doing so can ultimately lead to a catastrophic incident.

CEP: Spotlight on Safety - Discover Your Personal Process Safety Culture

Spotlight on Safety
John Herber
Culture can be defined as a collective group of shared beliefs and values that shape how we act. We think of culture as it relates to the actions and reactions of a group, company, or society. However, it can also characterize an individual — what influences how you make day-to-day decisions or handle various situations. Personal process safety culture can be assessed by observing someone’s (yours or another person’s) response to situations involving a safety violation.

CEP: Process Safety Beacon - Hazards of Strong Oxidizers

Process Safety Beacon
A worker was asked to move two open-top 5-gal pails containing aqueous sodium permanganate solution from one location to another. When he picked up the pails, the contents of one of them erupted, spraying him with the solution. Sodium permanganate is a strong oxidizer, and the splashed material set the worker’s clothing on fire. His injuries required hospital treatment.

CEP: Process Safety Beacon - Holiday Operations

Process Safety Beacon
Many plants shut down or reduce operations during a holiday period. Equipment may be in a non-standard condition while processes are on hold or shut down. Even though the plant is shut down, it is likely that hazardous materials are still present in storage tanks and process vessels. Equipment that is shut down may be opened for inspection or maintenance. Some plants continue to operate during a holiday but with reduced staff, delaying less-critical activities.
