The reservoir may be either pressurized or atmospherie. It must have suffieient eapaeity to eontain all oil during drain-baek or shutdown. It must be equipped with an oil level indieator, a low-level alarm switeh, safety relief valve, a pump for oil makeup during operation, drain valve, heater, mist eliminator, strainers, and required valves. Expander reservoirs must be designed and eonstrueted in aeeordanee with applieable ASME eodes. Reservoir retention time is typieally between 5-18 min depending on turboexpander size and manufaeturer s sizing eriteria. This is an area where the owner/purehaser should ask for the manufaeturer s assistanee. 

The filters should be located downstream of the coolers and should be equipped with a vent and orificed fill line to permit air removal prior to being put into service to prevent shocking the system. External lifts for the filter covers should be furnished if the covers are too heavy for an operator to safely handle. A suggested weight is 35 pounds, deferring however to operator safety. An adequate valved drain should be furnished for each filter body to permit easy removal of dirty oil and sludge. 

Safety requires you to think in advance about what you will do never do anything that seems dangerous. Know how to use safety equipment such as goggles, fume hood, lab coat, gloves, emergency shower, eyewash, and fire extinguisher. Chemicals should be stored and used in a manner that minimizes contact of solids, liquids, and vapors with people. Environmentally acceptable disposal procedures should be established in advance for every chemical that you use. Your lab notebook tells what you did and what you observed it should be understandable to other people. It also should allow you to repeat an experiment in the same manner in the future. You should understand the principles of operation of electronic and mechanical balances and treat them as delicate equipment. Buoyancy corrections are required in accurate work. Burets should be read in a reproducible manner and drained slowly for best results. Always interpolate between markings to obtain accuracy one deci-... 

The District Engineering Inspectors Report confirmed that the machine was completely isolated and the ammonia system was not protected by a safety valve or any type of pressure-relief device. The cause of the accident was the presence of the steam hose underneath the equipment to melt the ice on the drain valve or to help evacuate the system. The inspectors report could not determine if these preparations were intentional or accidental. [5]... 

In some instances, all waste materials are not collected in the same container. With certain pieces of equipment, strong acids or other hazardous materials are pumped directly into the drain. This shotild always be accompanied by a steady flow of water fi om the faucet. Safety glasses should be used by instrument operators when adds are pumped under pressure. 

Must ensure that the autoclave is located in a bounded area to control water leaks, has good access for maimenance, has an air-break in the drain line, has sample ports for sicam and water lesiing. is located in an area that allows for heat dissipation. Must demonstrate that all operating systems are working, that all safety systems are working, that the autoclave has been tested for leaks and other malfunctions, that there is cycle to cycle continuity of performance. Must include calibration of all control equipment... 

Liquid drains, manifolded and taken to a heater for vaporizing, process safety valves, vents and thaw lines, together with the major casing vents, all culminate in a vent stack to the atmosphere. This stack should have its exit point well above surrounding equipment to prevent it from being a hazard to personnel in the event of a fire. A continuous flow of nitrogen at a velocity of 1 ft/sec can be supplied at the bottom of the vent stack to blanket all process and casing equipment from air. A check valve placed in this line provides added protection. 

At the reagent bench obtain in a 10-mL or 100-mL graduated cylinder three times the required volume of 0.00070 M Fe + (from ferrous ammonium sulfate) plus a few milliliters in excess. Rinse the appropriate pipet twice with about 1-mL portions of 0.00070 M Fe2+ solution, draining the solution into a beaker for waste liquid. CAUTION Be certain to follow the procedure in Laboratory Methods B very carefully in order to draw liquids into pipets, preferably using a safety pjpet filler. Then measure the requiredvolumeof0.00070MFe2+ solution in triplicate, and drain the portions into separate 25-mL volumetric flasks (Laboratory Methods B) obtained from the equipment bench. Repeat the above procedure to add first 5.0 mL of a pH 4.0 buffer solution, then 1.0 mL of 0.72 M hydroxylamine hydrochloride, NH20H HC1, solution, and finally the appropriate volume of 0.00070 M 1,10-phenanthroline solution to each volumetric flask. what do you observe ... 

P IDs show all the process lines in a unit, including valves, material specs, and insulation detail. The P ID may or may not include minor piping such as vent and drain lines and tubing. They provide a pictorial representation of all equipment, instmmentation, and piping in a facility. They are crucial documents in almost all types of safety study and analysis. 

Hazards A negative pressure acting over some area of the body can create enough force to cause injury. A common example involves use of swimming and spa equipment and contact with fluid flowing into a drain or return port. The Consumer Products Safety Commission has reported numerous cases of children and adults coming into contact with an operational pool drain port. In some cases intestines were... 

The Safety Injection System (SIS) is isolated from the RCS during normal operation. Leakage from the RCS to the SIS under normal operation would be detected by SIS pressure, and alarmed when the pressure approaches the SIS design pressure. If design pressure is reached the safety valves will open and the water will flow to the equipment drain tank, where the change in level will quantify the leak. 

In order to prevent damage due to flooding, upon actuation of sprinkler systems, floor drains are provided and equipment is located to preclude the flooding of the equipment. In addition, in order to further reduce potential damage to safety-related equipment upon actuation of sprinkler systems, equipment is shielded and conduit ends are sealed where required based on interaction reviews during detailed design and as built walk-downs.
