Examine the threads on cylinder valves, regulators, and other fittings to ensure that they correspond to one another and are undamaged. Lab scenes in movies. Vessels must be strong enough to withstand the stresses encountered at the intended operating pressures and temperatures. This location prevents the production of electrical sparks inside the chemical hood when a device is plugged in or disconnected, and it also allows trained laboratory personnel to disconnect electrical devices from outside the hood in case of an accident. Fortunately, the cabinets had sliding doors that prevented the chemical containers from falling and breaking.
Cryogenic liquids must be stored, shipped, and handled in containers that are designed for the pressures and temperatures to which they may be subjected. Away from walls, water, and all metal materials including pipes. The primary method for the protection of laboratory personnel from airborne contaminants is to minimize the amount of such materials entering the laboratory air. To reduce the possibility of overpressurization of fittings or glassware, consider installing a vented pressure relief device on the water supply. Regulators used with oxidizing agents must be cleaned specially to avoid the possibility of an explosion on contact of the gas with any reducing agent or oil left from the cleaning process.

Set up and operate all vacuum operations with careful consideration of the potential risks. Also, if the system is closed after even a brief exposure to the atmosphere, some oxygen may have already condensed. If using a variable autotransformer (variac), be sure to wire (or rewire) new or existing equipment, as illustrated in Figure 7. The most common equipment-related hazards in laboratories come from devices powered by electricity, devices for work with compressed gases, and devices for high or low pressures and temperatures. As well as culturing cells and retrieving them from liquid nitrogen, she needs to observe correct laboratory procedure at all times in her role.
The unit was more than 25 years old and not designed to current safety standards, resulting in more physical damage than what would be expected. Because of acute or chronic toxicity unless special precautions have been taken to ensure continuous venting of the atmosphere inside the oven. Model 2 scenes in the lab answer. ) The primary hazards of cryogenic liquids are frostbite, asphyxiation, fire or explosion, pressure buildup (either slowly or due to rapid conversion of the liquid to the gaseous state), and embrittlement of structural materials. Use laboratory heating devices with a variable autotransformer to control and limit the input voltage to some fraction of the total line voltage, typically 110 V. If a variable autotransformer is not wired in this manner, the switch on it may or may not disconnect both wires of the output from the 110-V line when it is switched to the off position.
Note that the Occupational Safety and Health Administration (OSHA) Control of Hazardous Energy Standard (29 CFR § 1910. 147, Lock out/Tag out) applies. Finally, exercise extreme care when disassembling pressure equipment for repair, modification, or decommissioning. ) Other types of respirators are available for emergency or rescue work in hazardous atmospheres from which the wearer needs protection.

On applying a wrench to the fitting, the flexible hose disconnected completely and whipped off the regulator, striking the individual on the head, cheek, and abdomen, causing bruises and lacerations. The external cases of all variable autotransformers have perforations for cooling and ventilation, and some sparking may occur whenever the voltage adjustment knob is turned. 1 Fire Extinguishers. The valves must be rated for the intended pressure and temperature. It will also work in small group discussion, particularly if you intend to have the same group work on projects all year long. Never wear tight gloves when working with cryogenic liquids. Because significant breakthrough can occur at a fraction of the canister capacity, knowledge of the potential workplace exposure and length of time the respirator will be worn is important. High-voltage and high-power requirements are increasingly prevalent; therefore prudent practices for handling these devices are increasingly necessary.
These baths can be constructed from metal, ceramic, or, less desirably, glass vessels. Exposure to ultrasonically vibrating solids, such as an acoustic horn, can lead to rapid frictional heating and potentially severe burns. This overload protection is particularly useful for equipment likely to be left on and unattended for a long time, such as variable autotransformers (e. g., Variacs and powerstats), 2 vacuum pumps, drying ovens, stirring motors, and electronic instruments. The leaking cylinder can be moved through populated portions of the building, if necessary, by placing a plastic bag, rubber shroud, or similar device over the top and taping it (preferably with duct tape) to the cylinder to confine the leaking gas. The flying shrapnel damaged a refrigerator and freezer and gouged holes in the walls and ceiling. In carbon monoxide atmospheres, some alloys containing nickel or iron can generate carbonyls [e. g., Ni(CO)4] which are toxic when absorbed through the skin or inhaled. Laboratory hot plates are often used when solutions are to be heated to 100 °C or higher and the inherently safer steam baths cannot be used as the source of heat. The electric heaters used to defrost the freezing coils are also a potential spark hazard (see section 7. Test or inspect all pressure equipment periodically. Post warning signs on or near these devices to protect people wearing heart pacemakers. These kits are used to confine and limit the spill if such actions can be taken without risk of injury or contamination.
Where combustion is possible, the shielding material should be nonflammable or slow burning; if it can withstand the working blast pressure, laminated safety plate glass may be the best material for such circumstances. Who is doing it the correct way? However, a modified spark-proof refrigerator cannot meet the standards of an explosion-proof refrigerator. Therefore, locate these devices where water and other chemicals cannot be spilled onto them and where their movable contacts will not be exposed. Cally quenched to prepare the still bottoms for disposal. All regulators are typically of a diaphragm type and are spring-loaded or gas-loaded, depending on pressure requirements. When combinations of materials are required, consider the temperature dependence of their volumes so that leaks, ruptures, and glass fractures are avoided. The fly facility at the Francis Crick Institute looks after 1. Turn off nearby equipment and remove combustible materials from the area.
In a biomedical laboratory, cells are the living systems that many scientists use as biological models for their experiments. Note that NMR tubes are often thin-walled and should only be used for pressure reactions in a special high-pressure probe or in capillary devices. 4 Personal Safety Techniques for Use with Electrical Equipment. Because superconducting magnets use liquid nitrogen and liquid helium coolants, the precautions associated with the use of cryogenic liquids must be observed as well. ) At all timesStudents are allowed to go in storage rooms or preparation areas unless told not to. 1 Pressure-Relief Devices. Bimetallic strip thermometers are preferred for monitoring oven temperatures. Also see section 7. ) Second, the amount of organic matter placed in the furnace in the form of the polypropylene samples was significantly more than that in the usual paint samples. Contain heated oil in either a metal pan or a heavy-walled porcelain dish; a Pyrex dish or beaker can break and spill hot oil if struck accidentally with a hard object. When the nature of the leaking gas or the size of the leak constitutes a more serious hazard, an approved SCBA and protective apparel may be required, and personnel may need to be evacuated (see Chapter 6, section 6. Special cylinders that are insulated and vacuum-jacketed with pressure-relief valves and rupture devices to protect the cylinder from. When it is necessary to handle equipment that is plugged in, be certain hands are dry and, if feasible, wear nonconductive gloves and shoes with insulated soles. • Orient pressure-relief devices with the vent side of the device directed away from the operator or.
