  • Compressed Gas Cylinder Training
    Compressed Gas Cylinder Training PFW ANNUAL TRAINING Overview of Training Description of compressed gas cylinders How compressed gas cylinders are used Potential hazards of compressed gas cylinders Best practices for storage, transport, and use Description of compressed gas cylinders Compressed gas cylinders are portable tanks used to store, transport, and dispense gases for use in a broad range of industrial, research, and medical applications. The purpose of a high pressure gas cylinder is to serve as a reliable source of a specific type of gas for a specialized function. A large volume of gas is compressed into a relatively small volume of the cylinder… the result is a versatile high pressure cylinder that can be easily delivered where ever its needed . These cylinders are designed to be easy to handle BUT can create potential health and safety hazards if not properly handled. Description of compressed gas cylinders Common Industrial High Pressure Cylinder ◦ Height 5 ft. ◦ Diameter 9 in. ◦ Wall Thickness ½ in. steel ◦ Weight 140 lbs. ◦ Internal Capacity 1.8 ◦ Design Pressure 2,400 3psi Description of compressed gas cylinders A main fill and shut off valve is secured into the single opening at the top of the cylinder. When the cylinder is put into use, a pressure regulator is attached to reduce and control the pressure of gas flowing from the cylinder. When the cylinder is not in use, the regulator is typically removed and a protective cap can be screwed over the main valve for safe storage. Some cylinders have a built in protective ring in place of the cap.

  • Cylinder Valve Connections - Don’T Tamper with That Connection!
    Diversified CPC International, Incorporated 24338 West Durkee Road | Channahon, IL 60410 | 815-424-2000 Cylinder Valve Connections - Don’t Tamper with That Connection! Some History Any gas cylinder that you purchase is equipped with a valve outlet connection. Over the course of the last century the cylinder outlet connection has been studied, developed, and standardized in order to maximize safety and prevent the interconnection of incompatible gases or of gases at incompatible pressure ratings. The hazards of valve outlet connections first became apparent during World War I, where many different connections were being used, and there was no standardization amongst gas manufacturers. In the United States and Canada committees were subsequently formed to study the problem, and a standardization plan was eventually developed and accepted in 1949 as National Standards in both countries. Types and Characteristics of Valve Outlet Connections In North America, standard valve outlet connections are manufactured according to the specifications defined by the Compressed Gas Association (CGA). The CGA provides detailed descriptions of the dimensions and design of each connection, which are based on the flammability, toxicity, state and corrosiveness of the gas, as well as its pressure rating. The connections are generally identified by a 3-digit number (i.e. CGA 555). There are numerous other standards organizations around the world, such as British Standards (BS), the Deutsches Institut für Normung (DIN) in Germany, or Nederlandse Norm (NEN) in the Netherlands. Some Specialty Gas or Marine cylinders may occasionally be seen in North America, equipped with these valve outlet connections. Connections cover the wide range of gases and gas mixtures available today, including industrial gases, ultra-high integrity gases for the electronics sector, and breathing mixtures for the SCUBA (self-contained underwater breathing apparatus) industry.

  • LP-Gas Basic Filling Procedures General Information
    LP-Gas Basic Filling Procedures General Information Warning: Dispensing station to be operated only by a person who is certified according to Utah State Fire Prevention and Safety Law Title 53 Chapter 7 Part 3 Liquefied Petroleum Gas Act. The State Fire Marshals Office is not to be considered a source of training in the dispensing of propane. The following information is given as a reference to the dispenser certification test only. Training shall be provided by the LP-Gas Supplier and/or Management. NFPA 58 requires that “persons who transfer liquid LP-Gas shall be trained in proper handling and operating procedures.” Standard Precautions All weeds, grass, brush, trash, and any other combustible materials shall be kept not less than 10 ft. from the propane tank or point of transfer. Smoking, open flames, metal cutting or welding, portable electrical tools, extension lights, or any other source of ignition shall not be permitted within 25 ft. of the point of transfer during operation. Dispensing employee must stay in attendance at the tank, cylinder, or vehicle during the entire filling procedure until equipment is turned off and all valves are closed plugged and or capped. Self dispensing by the general public is strictly prohibited. Propane is a liquid which boils at -44 Degrees Fahrenheit to produce vapor or gas. Personal Protective Equipment (PPE) is required by OSHA when transferring liquid propane. Propane resistant gloves and eye protection shall be worn to prevent freezer burns from contact with liquid propane. Prior to filling ensure the valve is straight and undamaged. Look inside the valve opening for any obstructions such as dirt, sand, ice, insects, etc.

  • Carbon Dioxide
    Safetygram 18 Carbon dioxide Carbon dioxide is nonflammable, colorless, and odorless in the gaseous and liquid states. Carbon dioxide is a minor but important constituent of the atmosphere, averaging about 0.036% or 360 ppm by volume. It is also a normal end-prod- uct of human and animal metabolism. Dry carbon dioxide is a relatively inert gas. In the event moisture is present in high concentrations, carbonic acid may be formed and materials resistant to this acid should be used. High flow rates or rapid depressurization of a system can cause temperatures approaching the sublimation point (–109.3°F [–78.5°C]) to be attained within the system. Carbon dioxide will convert directly from a liquid to a solid if the liquid is depressurized below 76 psia (61 psig). The use of ma- terials which become brittle at low temperatures should be avoided in applications where temperatures less than –20°F (–29°C) are expected. Vessels and piping used in carbon dioxide service should be designed to the American Society of Mechanical Engineers (ASME) or Department of Transportation (DOT) codes for the pressures and temperatures involved. Physical properties are listed in Table 1. Carbon dioxide in the gaseous state is colorless and odorless and not easily detectable. Gaseous carbon dioxide is 1.5 times denser than air and therefore is found in greater concentrations at low levels. Ventilation systems should be designed to exhaust from the lowest levels and allow make-up air to enter at a higher level. Manufacture Carbon dioxide is produced as a crude by-product of a number of manufactur- ing processes.

  • Standard Methods for the Examination of Water and Wastewater
    Standard Methods for the Examination of Water and Wastewater Part 1000 INTRODUCTION 1010 INTRODUCTION 1010 A. Scope and Application of Methods The procedures described in these standards are intended for the examination of waters of a wide range of quality, including water suitable for domestic or industrial supplies, surface water, ground water, cooling or circulating water, boiler water, boiler feed water, treated and untreated municipal or industrial wastewater, and saline water. The unity of the fields of water supply, receiving water quality, and wastewater treatment and disposal is recognized by presenting methods of analysis for each constituent in a single section for all types of waters. An effort has been made to present methods that apply generally. Where alternative methods are necessary for samples of different composition, the basis for selecting the most appropriate method is presented as clearly as possible. However, samples with extreme concentrations or otherwise unusual compositions or characteristics may present difficulties that preclude the direct use of these methods. Hence, some modification of a procedure may be necessary in specific instances. Whenever a procedure is modified, the analyst should state plainly the nature of modification in the report of results. Certain procedures are intended for use with sludges and sediments. Here again, the effort has been to present methods of the widest possible application, but when chemical sludges or slurries or other samples of highly unusual composition are encountered, the methods of this manual may require modification or may be inappropriate. Most of the methods included here have been endorsed by regulatory agencies. Procedural modification without formal approval may be unacceptable to a regulatory body.
