CEP: Spotlight on Safety - Personal Growth and Lessons Learned from Two Global Tragedies

November
2014
Spotlight on Safety
Louisa Nara
The 30-year anniversaries of two events of significance to the chemical engineering profession, particularly the process safety community, occur in November and December — the PEMEX disaster outside of Mexico City, Mexico, and the Union Carbide Corp. tragedy in Bhopal, India. These two incidents, two-and-a-half weeks apart, molded my professional career and ultimately motivated me to work for the Center for Chemical Process Safety (CCPS) at AIChE, where our mission is to prevent such tragedies from occurring.

CEP: Spotlight on Safety - Verify, then Act

Spotlight on Safety
Louisa Nara
Verify-then-act is a practice and mindset that all engineers and personnel in the chemical process industries (CPI) should adopt. Mixing the wrong chemicals, setting temperatures or pressures outside of safe operating limits, or performing a step out of sequence can result in a range of consequences, from a bad batch or loss of production to a catastrophic incident. However, simply verifying before acting can reduce the risk of these penalties and save time, money, and lives.

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

February
2014
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: Spotlight on Safety - Be Prepared, Be Safe, and Have Fun

August

Spotlight on Safety
Louisa Nara
One of my favorite warm weather activities is kayaking. The river provides a respite away from crowds and electronic distractions. Daily stressors are erased by the warm sun, a light breeze, and the sound of water lapping at my boat. A recent weekend with great weather afforded the perfect opportunity to go out on the river with my husband. Earlier that week, severe storms blew through the area with significant rainfall and flash flooding. This increased the volume of water in the river, so conditions would be perfect for a fast and exciting ride. It also called for a more-mindful approach to safety hazards, like swift currents and debris in the water.

CEP: Spotlight on Safety - Sensing Safety

August
2015
Spotlight on Safety
Louisa Nara
Most of us are fortunate enough to have five working senses — sight, hearing, touch, smell, and taste. We use these personal, internal feedback loops to perceive and understand our surroundings, which makes our senses some of our most valuable and essential safety equipment. Before the advent of optical, vibrational, and auditory sensors, the chemical process industries (CPI) depended on sensory perception to identify operational upsets or changes. Although sensing equipment is now ubiquitous in CPI facilities, we must also use our senses to collect critical safety data, rather than blindly relying on equipment to signal unsafe conditions.
