Keystone Engineering Group, Inc. (Keystone) delivered two (2) one-hour presentations at the Delaware Rural Water Association 13th Annual Water & Wastewater Operators Expo. The presentations covered the fundamentals of Cybersecurity for SCADA Systems and Electrical Safety Awareness for Water and Wastewater Facilities. The presentations were well attended, with attendees representing water/wastewater utilities, municipalities, and various corporations local to the DelMarVa Peninsula.
Jeremy Cherelli, P.E., Director of Programming at Keystone, delivered an informative presentation on the importance of Cybersecurity in SCADA systems. The presentation focused on various threats to Human Machine Interfaces, (HMIs), Supervisory Controls and Data Acquisition (SCADA), and Industrial Control Systems (ICS) hosts including, intrusions through external network connections, physical intrusions, and inadvertent intrusions through the use of infected USB devices. Jeremy provided the audience with methods for assessing and evaluating a facility’s vulnerabilities, segmenting a facility’s network, as well as continuity and disaster recovery methods. The presentation provided a good explanation of why Cybersecurity is important, and the potential consequences for failing to maintain a secure facility and network.
Curtis James, P.E., Electrical Engineer with Keystone, provided an interesting electrical safety presentation including real-life case studies, shock hazards, mitigating workplace hazards, and Arc Flash hazards. The presentation started with real-life case studies involving fatalities associated with exposure to 120 Volt up to 480 Volt. Transitioning from the real-life case studies, the presentation focused on shock hazards and the potential health ramifications from electrical shocks. The shock hazard segment was immediately followed by methods for avoiding electrical shock exposure by discussing the Hierarchy of Controls used in NFPA 70E, including proper labeling, fingersafe guards, and lockout/tagout. The presentation concluded with a discussion about Arc Flash hazards, the consequences of an Arc Flash event, and the importance of having an Arc Flash study completed for each facility.
