These remote I/O systems are now more compact

August 1, 2011 | By Chemical Engineering

LB/FB Remote I/O Systems are used to connect intrinsically safe Namur switching signals and solenoid valve outputs as well as temperature inputs, or the supply of two- or four-wire transmitters, proportional valves and positioners. LB Remote I/O is installed in the safe area or Zone 2 Div. 1, while the encapsulated FB Remote I/O can be installed in Zone 1. Both employ the same electronic boards in their plug-in modules. These have now been modernized to comply with the latest ATEX guidelines and standards, while remaining compatible with existing devices. Standard buses, such as Profibus, Modbus or industrial Ethernet are available for connecting to master systems. The devices feature new, compact redundant backplanes to save space and reduce costs. Extended intrinsic safety parameters facilitate new interconnections with even more field devices. — Pepperl+Fuchs GmbH, Mannheim, Germany

Session Briefing 1 / 6

When a major incident strikes, the people stepping into Incident Command aren't always the ones who trained for it. Engineers, operators, trades supervisors, and compliance specialists may suddenly find themselves filling Command and General Staff roles — not because they volunteered, but because the situation demands it. Panelists will share practical strategies for leading without positional authority, tools and frameworks that help personnel rapidly orient to ICS roles, and approaches for closing the gap between day-to-day job functions and emergency command readiness before the next incident makes it urgent.

This session will examine produced water as the largest waste stream in the oil and gas industry and one of its most pressing emerging challenges. It will address the growing volumes of produced water, the increasing regulatory and public scrutiny of constituents such as PFAS, salts, and Naturally Occurring Radioactive Material (NORM), and the operational implications for management, treatment, reuse, and disposal. The discussion will also explore how operators, regulators, and communities are redefining approaches to produced water management in response to environmental, technical, and stakeholder pressures.

This session will present a detailed case study of a large-scale lithium-ion battery fire response that extended over 12 months. Attendees will explore the hazards associated with thermal runaway events, the operational challenges of suppressing lithium battery fires, and the response strategies that proved effective in this prolonged incident. The

Drawing on insights from U.S. EPA Region 9 wildfire response efforts, the session will also highlight tactics such as hazard characterization, air monitoring and evaluation, and household hazardous waste collection and disposal. Participants will leave with a stronger understanding of the complexities involved in large-scale battery fire incidents and the critical factors to consider when planning and executing an effective response.

This session introduces use of remote sensing technologies to detect, characterize and monitor spills across marine and coastal environments. Discussion will highlight how tools can integrate into modern spill response workflows to improve safety and support data-driven decision making.

This session provides a practical, ground‑level introduction to the essential steps required after a battery undergoes a thermal event. We’ll break down how to assess site conditions, stabilize and prepare damaged cells or packs, select appropriate containment and packaging methods, and navigate the regulatory landscape that governs transport and disposal. The lecture emphasizes real‑world decision‑making, safety considerations, and compliance requirements, giving participants a clear framework they can apply immediately in field operations or emergency response planning.
