CBS SOP: Liquid Nitrogen AODA
Liquid Nitrogen SOP Liquid Nitrogen SOP CBS-SOP-020-19 Effective: Mar 2019 Author: A. Holliss Edited: P. Scheffer Purpose To provide procedural guidance on the dispensing, transport, handling and disposal of liquid nitrogen. This document is to be used in addition to on the job training and not as a substitution. Scope All students and staff within CBS working with liquid nitrogen should be familiar with these procedures. Outside of normal working hours (weekdays 08:30 to 16:30) liquid nitrogen must not be dispensed from the pressurized storage vessel. If there is an absolute necessity for liquid nitrogen from the pressurized storage dewar at that time, this procedure must be carried out with the supervisor’s knowledge by two trained personnel working together to allow for the alarm to be raised if there is an incident/accident. The second ‘spotter’ person is to be in visual contact with the first ‘dispensing’ person but not so close to also be in danger. Definitions/Acronyms Cryogenic storage dewar – a specialized double-walled vacuum container used for storing cryogenic liquid and provides thermal insulation as the cryogenic liquid slowly boils away. Excessive pressure is released through an open top, vented cap or through a pressure relief valve to prevent the risk of explosion. Oxygen deficient atmosphere – an atmosphere with less than 19.5% oxygen by volume. Air normally contains approximately 21% oxygen. If gases other than oxygen are added or mixed with air, the oxygen concentration is reduced (diluted) and oxygen deficiency occurs. No human sense will give an indication of an oxygen-reduced atmosphere. -
Thermometer 1 Thermometer
Thermometer 1 Thermometer Developed during the 16th and 17th centuries, a thermometer (from the Greek θερμός (thermo) meaning "warm" and meter, "to measure") is a device that measures temperature or temperature gradient using a variety of different principles.[1] A thermometer has two important elements: the temperature sensor (e.g. the bulb on a mercury thermometer) in which some physical change occurs with temperature, plus some means of converting this physical change into a numerical value (e.g. the scale on a mercury thermometer). A clinical mercury-in-glass thermometer There are many types of thermometer and many uses for thermometers, as detailed below in sections of this article. Temperature While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. There is today an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this closely, based on fixed points and interpolating thermometers. The most recent official temperature scale is the International Temperature Scale of 1990. It extends from 0.65 K (−272.5 °C; −458.5 °F) to approximately 1358 K (1085 °C; 1985 °F). Thermometer Thermometer 2 Development Various authors have credited the invention of the thermometer to Cornelius Drebbel, Robert Fludd, Galileo Galilei or Santorio Santorio. The thermometer was not a single invention, however, but a development. Philo of Byzantium and Hero of Alexandria knew of the principle that certain substances, notably air, expand and contract and described a demonstration in which a closed tube partially filled with air had its end in a container of water.[2] The expansion and contraction of the air caused the position of the water/air interface to move along the tube. -

Chapter 1 -- Taking the Temperature of the Planet Peter deMenocal “The heat is on” - Glenn Frey 31 December, 1768: “No one can recall such a mild Autumn: the ground is as green as in the Spring, and today I have picked sufficient young nettles, dandelions, and other herbs to cook green cabbage tomorrow, which is New Year’s day.” Colorful mixes of meteorology and domestic concerns are typical of weather diaries kept by diligent observers for centuries. This example, from the Stockholm Observatory in Sweden, is not unusual, but it does pose prob- lems for those interested in climate change. For instance, exactly how mild was that autumn and how might it compare to autumn in 2007? To answer those questions and others like them, these qualitative descriptions are not sufficient—quantitative measures are required. Galileo Galilei developed the first thermomete in the late 1500s. The “thermoscope”, as beautiful as it was imprecise, was an elegant liquid-filled glass cylinder hosting several colorful, sealed glass bulbs that rose and sank with changes in temperature as their density relative to the liquid changed. More accurate measurements became available two centuries later, when German physicist Daniel Fahrenheit developed the sealed mercury thermometer in 1714 and the temperature scale that bears his name. As with many scientific advances, this new way of reducing nature to numbers lead to a new way of viewing the climate. No longer was the difference between one year and another simply a qualitative change – warmer, cooler, wetter – but a difference that could be reliably quantified. These records gave rise to the statistics of weather and eventually to the possibility of detecting subtle changes in climate. -

So it’s appropriate that Jessica Anderson showed up for school the day before Halloween dressed as a domino. Anderson has no objection to fun and games in the classroom. In fact, she uses games extensively to teach science concepts. “Our entire classroom is a game,” she said. Her students love it — to the point of not wanting to leave sometimes when class is over. “Students who typically struggle in school frequently excel under Jessica’s leadership,” says her school principal, Kerry Glisson. Anderson’s innovation and non- stop energy recently earned her the Finalist Derek Strahn, Teacher of the Year Jessica Anderson, and inalist Shelly title of 2016 Montana Teacher of Stanton at the Teacher of the Year Celebration Oct. 15.
