A safety relay that is certified for SIL 2

October 1, 2012 | By Chemical Engineering

The Safety Relay Module (SRM) is said to be a versatile relay repeater module that has been certified by Exida for single use in safety-instrumented systems (SIS) up to SIL 2. The SRM is part of the company’s FS Functional Safety Series and accepts single-contact closure inputs from logic-solver trip outputs, including the STA Safety Trip Alarm and the SPA2 Programmable Limit Alarm Trip. With three contacts per alarm input, the SRM allows for the addition of alarm contacts to safety processes without special installation or configuration. — Moore Industries International, Inc., North Hills, Calif.

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.
