Process Safety Beacon: Hydrate Hazards

January
2016
Process Safety Beacon
Water can be a hazard in process plants. When water is mixed with some materials, typically gases but also liquids, it can form a crystaline, ice-like solid. This solid is called a hydrate. When a hydrate forms, it can plug piping, instrument connections, valves, and other equipment, which causes process upsets that may be hazardous. Hydrogen sulfide, acetylene, methyl mercaptan, chlorine, vinyl fluoride, carbon dioxide, ethylene, methane, ethane, natural gas, and other hydrocarbon gases can form hydrates.

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

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

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

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.

CEP: Spotlight on Safety - Verify, then Act

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.
