2); thus, thermal distillation processes should be a last resort. Trained laboratory personnel must know how to safely shut down equipment in the event of an emergency; must enclose or shield hazardous parts, such as belts, chains, gears, and pulleys, with appropriate guards; and must not wear loose-fitting clothing, jewelry, or unrestrained long hair around machinery with moving parts. The cause of the incident was the use of a rotor that was not approved for the particular unit. All trained laboratory personnel should know where the safety showers are located in the work area and should learn how to use them. Commercial cylinders of liquefied gases are normally supplied only with a fusible-plug type of relief device, as permitted by DOT regulations. Lab scenes in movies. Wear proper protective gloves when handling a hot bath. Replace two-prong receptacles as soon as feasible, and add a separate ground wire so that each receptacle is wired as shown in Figure 7.
Hand injuries are the most frequently encountered injuries in laboratories. • Wear insulating rubber gloves when working with electrical equipment. Keep it closed until cool. Protect pressurized containers that contain cryogenic material with multiple pressure-relief devices. Never put makeup on in the lab. Handle objects that are in contact with cryogenic liquids with tongs or potholders. Styrofoam buckets with lids can be a safer form of short-term storage and conveyance of cryogenic liquids than glass vacuum Dewar flasks. An attempt was made to repair the leak while the system was still pressurized. Model 2 scenes in the lab answers. 4. at the handles onlyIf you have a medical condition, who should you talk to before working in the lab? • The maximum setting of a pressure-relief device is the rated maximum allowable working pressure (MAWP) established for the vessel or for the weakest member of the pressure system at the operating temperature. Likewise, never substitute the fittings that are on either the cylinder side or downstream (low-pressure) side of a vendor-supplied regulator. What should Sue have done to avoid an accident? Placing potentially explosive (see Chapter 6, sections 6. A pressure gauge is normally a weak point in any pressure system because its measuring element must operate in the elastic zone of the metal involved.
Remove regulators from corrosive gases immediately after use and flush with dry air or nitrogen. Difficulty in breathing or the detection of odors indicates plugged or exhausted filters or cartridges or concentrations of contaminants higher than the absorbing capacity of the cartridge, and the user should immediately leave the area of contamination. In addition to the spark hazard, old and corroded bimetallic thermostats in these devices can eventually fuse shut and deliver full continuous current to a hot plate. Then, when the liquid nitrogen bath is removed or when it evaporates, the condensed. Train personnel operating or working in the vicinity of these types of equipment appropriately to minimize the risk of exposing themselves and others in the laboratory to harmful ionizing radiation. For these reasons, heat guns almost always pose a serious spark hazard (see Chapter 6, section 6. Because it is sharp and you may get injured from itWhat should you use to handle broken glass in the lab? Model 2 scenes in the lab answer. After removal of all visible mercury, monitor the heated oven in a laboratory chemical hood until the mercury vapor concentration drops below the threshold limit value. Do not use ovens to dry any chemical sample that has even moderate volatility and might pose a hazard. Deactivate the stills under argon or nitrogen, never air. 'Craft and Graft' w1 takes a look behind the scenes at the many different teams that support the biomedical research carried out at the Francis Crick Institute in London – from bottle-washing to breeding flies. The electric heaters used to defrost the freezing coils are also a potential spark hazard (see section 7. Do not present shock or spark risks, they can be left unattended with assurance that their temperature will never exceed 100 °C. Stills in use should be attended at all times and should have an automatic high-temperature shutoff.
Low-oxygen alarms are recommended in rooms where instruments with superconducting magnets are located. Against paper and trash or metal fires and are not recommended for fires involving delicate instruments or optical systems because of the cleanup problem. Virtually all liquid gases present the threat of poisoning, explosion, or, at a minimum, asphyxiation in a confined space. • Equip motor-driven electrical equipment used in a laboratory where volatile flammable materials may be present with either nonsparking induction motors that meet Class 1, Division 2, Group C-D electrical standards (Earley, 2008; NFPA, 2008) or air motors instead of series-wound motors that use carbon brushes, such as those generally used in vacuum pumps, mechanical shakers, stirring motors, magnetic stirrers, and rotary evaporators. Where should you grasp sharp instruments? Each regulator is supplied with a specific CGA standard inlet connection to fit the outlet connection on the cylinder valve for the particular gas. • Gas manifolds, compressors, and other sources of high-pressure gas used to supply an apparatus, and which can be isolated from the apparatus by valving, should also be protected by a properly designed pressure-relief device. 5 MPa (500 psi) because of the danger of weakening carbon steel equipment by hydrogen embrittlement. The stirring and mixing devices commonly found in laboratories include stirring motors, magnetic stirrers, shakers, small pumps for fluids, and rotary evaporators for solvent removal. 2 Equipment Used with Compressed Gases. 1 Records, Inspection, and Testing. When cost, transparency, high-tensile strength, resistance to bending loads, impact strength, shatter resistance, and burning rate are considered, poly(methyl methacrylate) offers an excellent overall combination of shielding characteristics. • Examine safety showers and eyewash units visually and test their mechanical function.
Use appropriate gloves and a face shield to avoid contact with the skin when using cold baths. Make all connections by using, preferably, a plug-and-receptacle combination, or wires with insulated terminals firmly secured to insulated binding posts. A trap containing frozen argon is indistinguishable from one containing condensed solvent or other volatiles and presents an explosion hazard if allowed to warm without venting. In the event of a quench, all personnel should leave the area and not return until oxygen levels return to normal. Plastic locking disconnects can make it easy to unfasten water lines without having to unclamp and reclamp secured lines. • Cut-resistant gloves, such as Kevlar® or leather gloves, are appropriate for handling broken glassware, inserting tubing into stoppers, and handling sharp-edged objects if protection from chemicals is not needed. The glass may shatterYou shouldn't immerse --- glassware in ----, coldWhy should hair, clothing, and hands be at a safe distance from a flame? • After making modifications to an electrical system or after a piece of equipment has failed, do not use it again until it has been cleaned and properly inspected. As a result, there is a significant savings in electricity usage, although heating jackets may be required for installations where the water and oxygen scavengers are activated or regenerated. If the motion of the impeller is impeded, the rubber can twist away from the motor shaft, and the motor will not stall.
Thus, do not dry most organic compounds in a conventional unvented laboratory oven. Check for proper mounting of the extinguisher and that it is readily accessible. Shoe covers may be required for work with especially hazardous materials. • Avoid becoming grounded by staying at least 6 in. Do not use water-soluble ink; labels should be waterproof or covered with transparent tape. If use of an extension cord is necessary, use only a three-wire cord with a rating equal to or greater than that for the oven. Resistance devices used to heat oil baths should not contain bare wires. Examine newly fabricated or repaired glass equipment for flaws and strains under polarized light.
ImmediatelyWhat are examples of damaged electrical equipment? As previously noted, use only hot plates that have completely enclosed heating elements in laboratories. Start the process at the beginning of the day and let it run as long as laboratory workers are present. Direct sunlight can damage eyes, use a desk lamp instead.
2. turn off gas valves. If the temperature sensor for the controller is not properly located or has fallen out of place, the controller will continue to supply power until the sensor reaches the temperature setting, creating an extremely hazardous situation. • Do not move an injured person unless he or she is in danger of further harm. If such metal-enclosed mantles are used, good practice is to ground the outer metal case either by using a grounded three-conductor cord from the variable autotransformer or by securely affixing one end of a heavy braided conductor to the mantle case and the other end to a known electrical ground. Thermal distillation uses an average of 70, 000 gal of water per coolant line, per year; the column purification system uses no water. Do not use variable autotransformers to control the speed of an induction motor. Do not use vessels or equipment made partly or entirely of silver or copper or alloys containing more than 50% copper in contact with acetylene or ammonia. Each pressure vessel in a laboratory should have a stamped number or fixed label plate that uniquely identifies it.
