Water has an extraordinarily high specific heat capacity and also a high heat of vaporization.One water molecule may participate in a maximum of four hydrogen bonds with other species. Water readily forms hydrogen bonds with other water molecules. The chemical bonds between hydrogen and oxygen atoms in a water molecule are polar covalent bonds.Water is the third most abundant molecule in the universe, after hydrogen gas (H 2) and carbon monoxide (CO).Nearly all of that water (98.8 percent) is in ice and groundwater. Only about 2.5 percent of the Earth's water is freshwater.Breaking it down, 96.5 percent of the water in the Earth's crust is found in oceans, 1.7 percent in ice caps and glaciers, 1.7 percent in groundwater, a small fraction in rivers and lakes, and 0.001 percent in clouds, water vapor, and precipitation. About 71 percent of the Earth's surface is covered by water.The reason for the blue color is the weak absorption of light at the red end of the visible spectrum. Large volumes of liquid water and ice are blue. In its liquid form, water is transparent and nearly colorless.Approximately 62 percent of the human body is water. Water is the main compound found in living organisms.These CEUs are recognized by the FDEP, as well as many other state licensing boards thanks to reciprocity agreements.All attendees have the benefit of receiving approved CEUs/PDHs (from either the ISA or FSAWWA) for the hours spent in the training course and symposium towards their water/wastewater operator and PE license continuing education requirements. Attendees can receive Florida Department of Environmental Protection (FDEP) approved CEUs and PDHs for the training course, as certified by the Florida AWWA. Read the training course CEU/PDH certification. The ISA has also partnered with the Florida Section of the AWWA and the Water Environment Federation (WEF) to certify training credits for use for state-licensed water and wastewater operators, and for state-registered professional engineers. As a result of their Authorized Provider membership status, ISA is authorized to offer IACET CEUs for its programs that qualify under the ANSI/IACET 1-2007 Standard. In obtaining this approval, ISA has demonstrated that it complies with the ANSI/IACET 1-2007 Standard which is widely recognized as a standard of good practice internationally. ISA is an approved Authorized Provider by the International Association for Continuing Education and Training (IACET), 1760 Old Meadow Road, Suite 500, McLean, VA 22102 (703) 506-3275. When not working, or reading, Nick and his wife Ruth run a recreational sled dog team. Nick’s path to instrumentation and control started when he earned his BS in Chemical Engineering from Virginia Tech. He followed Vernon Trevathan as editor for ISA’s The Guide to the Automation Body of Knowledge as well as authoring the chapter on alarm management. Nick is co-chair of Standards & Practices committee 18 working on alarm management, and was the lead editor for the new standard, ANSI/ISA-18.02-2009, Management of Alarm Systems for the Process Industries. He is the author of DuPont’s best practices on alarm management. ![]() He led two company alarm management teams from the early 1990s to the early 2000s. Over the last 18 years, Nick has worked on several alarm management projects, both for new plants and existing plants. In his 19 years with DuPont he has been a business process control leader, site process control leader, process control consultant, and plant control engineer in several different businesses. ![]() Instructor: Nick Sands, PE, ISA Fellow – bioĬourse Fee: $650 ISA Members, $815 List Price – RegisterĪbout the Instructor Nick Sands is currently a process control engineer working for DuPont’s Kevlar® and Nomex® businesses. Introduction to the Management of Alarm Systems (IC39C) We are pleased to offer two optional SCADA training courses in conjunction with the 2017 WWAC Symposium.
