Keep people wearing heart pacemakers and other electronic or electromagnetic prosthetic devices or other potentially magnetic surgical implants, such as aneurysm clips, away from strong magnetic sources. Who is following the rules? Over a year, the team cleans around 750 000 flasks, test tubes and beakers. Open cylinder valves slowly, and only when a proper regulator is firmly in place and the attachment has been shown to be leakproof by an appropriate test. Lab scenes in movies. The process involves reflux and distillation of organic solvents (many of which are flammable liquids) over drying materials, under nitrogen or argon gas. • Render immediate first aid; appropriate measures include washing under a safety shower, administration of CPR by trained personnel if heartbeat or breathing or both have stopped, and special first-aid measures. The plugCan hands be wet (but only very little) when touching electrical equipment?
In addition, the potential for a flood is greatly increased. Appropriate laboratory eye and face protection includes impact goggles with splash protection (chemical splash goggles), full-face shields that also protect the throat, and specialized eye protection (i. e., protection against ultraviolet light or laser light). Safety first model 2 scenes in the lab answers. If the motion of the impeller is impeded, the rubber can twist away from the motor shaft, and the motor will not stall. Empty compressed gas cylinders purchased for the laboratory should be returned to the company and should never be refilled by laboratory personnel. Cold traps under continuous use, such as those used to protect inert atmosphere dryboxes, should be electrically cooled, and their temperature should be monitored with low-temperature probes. A compressed gas is defined as a material in a container with an absolute pressure greater than 276 kPa, or 40 psi at 21 °C or an absolute pressure greater than 717 kPa (104 psi) at 54 °C, or both, or any liquid flammable material having a Reid vapor pressure greater than 276 kPa (40 psi) at 38 °C.
Inspect all tubing frequently and replace when necessary. T/FTWhen you use sharp instruments: 1. point the tips where? Model 2 scenes in the lab answers. Standard cylinder-valve outlet connections have been devised by CGA to prevent the mixing of incompatible gases due to an interchange of connections. Check and clean chemical cartridge respirators on a regular basis. In principle, these spark hazards are alleviated by enclosing all mechanical contacts in a sealed container or by using solid-state circuitry for switching and temperature control.
Testing the entire apparatus with soap solution and air or nitrogen pressure to the maximum allowable working pressure of the weakest section of the assembled apparatus usually detects leaks at threaded joints, packings, and valves. However, personnel who spend significant time working on video display terminals should use furniture appropriate for these tasks, proper posture, and perhaps special eyeglasses.

Some types of extinguishers must be weighed annually, and periodic hydrostatic testing may be required.
The training should be an American Heart Association cardiopulmonary resuscitation (CPR)/AED course or a nationally acceptable equivalent. The reaction container used in a molten salt bath must be able to withstand a very rapid heat rise to a temperature above the melting point of the salt. Appropriate precautions using the proper shielding must be taken for condensing materials and sealing tubes. • Install GCFIs as required by code to protect users from electric shock, particularly if an electrical device is handheld during a laboratory operation. These baths can be constructed from metal, ceramic, or, less desirably, glass vessels.
If sealed containers must be used, select their materials carefully and the containers properly designed. Also, if this wiring scheme has not been followed, and especially if the grounded three-prong plug is not used, even when the potential difference between the two output lines is only 10 V, each output line may be at a relatively high voltage (e. g., 110 V and 100 V) with respect to an electrical ground. • Ensure that all laboratory personnel know the location and operation of power shutoffs (i. e., main switches and circuit breaker boxes) for areas in which they work. This precaution is necessary not only for safety when the cylinder is under pressure but also to prevent the corrosion and contamination that would result from diffusion of air and moisture into the cylinder when it is emptied. The fire was extinguished immediately but continued to flare up because the oil was still above its autoignition temperature. The four types of most commonly used extinguishers are listed below, classified by the type of fire for which they are suitable. Clothing that leaves large areas of skin exposed is inappropriate in laboratories where hazardous chemicals are in use. 4. at the handles onlyIf you have a medical condition, who should you talk to before working in the lab?
The tubes can be heated with steam or in a specially constructed, electrically heated sealed-tube furnace that is controlled thermostatically and located to direct the force of an explosion into a safe area. The operating pressure should be less than the system MAWP. Human exposure to ultrasound with frequencies of between 16 and 100 kHz can be divided into three distinct categories: airborne conduction, direct contact through a liquid-coupling medium, and direct contact with a vibrating solid. For those solvents that are incompatible with copper (e. g., tetrahydrofuran, methylene chloride, acetonitrile), a second column of alumnia is used along with a dry nitrogen or argon purge to facilitate oxygen removal. Absorbent gloves could freeze on the hand and intensify any exposure to liquefied gases. A fog can be used safely and effectively against fires that involve oil products, as well as those involving wood, rags, and rubbish. 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. Also, the on/off switches and fan motors are not usually spark-free.
Never store reserve stocks of such cylinders in the vicinity of cylinders containing oxidizing gases including oxygen, fluorine, and chlorine.

The material should not react with the process being studied, and the vessel must be of the proper size and configuration. For information about reducing the use of mercury in laboratories, see Chapter 5, section 5. Thus, using a variable autotransformer that controls voltage and not frequency could cause the motor to overheat and presents a fire hazard. What should Bob do after the accident? With school-level science qualifications and a background in practical work, Nick has been a glass wash technician since 2006.
A flame or any heat sourceWhy shouldn't you remove chemicals or other materials from the laboratory area? • When bringing ordinary electrical equipment such as vacuum cleaners and portable electric drills having series-wound motors into the laboratory for special purposes, take specific precautions to ensure that no flammable vapors are present before such equipment is used (see Chapter 6, section 6. He determined that the oil in an oil bath was burning. The cylinder was placed in an area with adequate ventilation and allowed to empty. The temperature was set to ramp up to 900 °C. Where concentrations of air contaminants could be immediately dangerous to life, such respirators can be used provided (a) the protection factor of the respirator is not exceeded and (b) the provisions of OSHA's Respiratory Protection Standard (which indicates the need for a safety harness and an escape system in case of compressor failure) are not violated. This problem can be minimized by placing the thermoregulator fairly close to the heater. Do not store new and used cartridges near chemicals because they are constantly filtering the air. For example, the large attractive force of an NMR requires that objects ranging from keys, scissors, knives, wrenches, other tools, oxygen cylinders, buffing machines, and wheelchairs, and other ferromagnetic objects are excluded from the immediate vicinity of the magnet to protect safety and data quality. Care should be taken to use appropriate gloves when handling laboratory equipment to protect against electrical, thermal, and chemical burns, cuts, and punctures. In the proper disposal containerInserting and removing glass tubing from rubber stoppers can be dangerous. • 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. For the same reason, fit oil baths left unattended with thermal-sensing devices that turn off the electric power if the bath overheats.
ASME) Boiler and Pressure Vessel Code (ASME, 1992) is mandatory. Secure compressed gas cylinders firmly at all times. Warn laboratory personnel of the spark hazard associated with these hot plates. Mount pressure gauges so that they are easily read during operation. Never leave the cylinder valve open when the equipment is not in use. To avoid exposure to microwaves, never operate ovens with the doors open.
