Equipment special needs

Use special equipment for sampling, where necessary, for meeting the special needs of different batches (e.g., hot/toxic)... [Pg.137]

This is a destructive method in which the resin is ground and pelleted as a KBr disc and analysed by FT-IR analysis. This method works best for systems where disdnct ftinctional group transformations (C=0, C-OH, C=C, etc) are expected. No special equipment is needed. [Pg.75]

Slant rig Drilling rig specifically designed to drill a wellbore that is nonvertical at the surface. The mast is slanted and special pipe-handling equipment is needed. [Pg.1082]

Endosulfan and its breakdown products can be measured in your blood, urine, and body tissues if you have been exposed to a large amount. Tests to measure endosulfan in such bodily tissues or fluids are not usually available at a doctor s office because special equipment is needed. [Pg.29]

Two parameters determine the points awarded in the capital investment category total number of steps and whether or not special equipment is needed (Table 2.3). [Pg.21]

The team s laboratory specialist will make certain that all the equipment he needs is in operating order before startup. He will need to familiarize himself with not only the tests that will be regularly performed, but any others that may be useful in diagnosing startup problems. He may arrange for the use of a number of special... [Pg.364]

There is a test that can detect acrylonitrile in blood. In addition, the major breakdown products of acrylonitrile by the body (termed metabolites) can be measured in urine. Some breakdown products that can be measured are specific to acrylonitrile. However, one breakdown product of the body (cyanide) that is commonly measured is not specific to acrylonitrile exposure, and the results can be affected by cigarette smoking. Because special equipment is needed, these tests cannot be performed routinely in your doctor s office. There is not enough information at present to use the results of such tests to predict the nature or severity of any health effects that may result from exposure to acrylonitrile. Further information on how acrylonitrile can be measured in exposed humans is presented in Chapters 2 and 6. [Pg.12]

Any procedures they may need to follow to respond to or otherwise protect themselves in response to an emergency such training should include the use of any personal protective equipment, special tools, or equipment required for these actions. [Pg.119]

The particle size and distribution in soils can be easily determined by the sedimentation method. It is based on the fact that large particles will settle faster than smaller ones. No special equipment is needed. [Pg.459]

Several tests are available to tell whether you have been exposed to bromomethane, but each has limitations. The most direct test measures bromomethane in your blood or in the air you breathe out. However, this test is not usually used because most bromomethane does not stay in the body very long (see Section 1.3) and special measuring equipment is needed. More often, the main breakdown product of bromomethane (bromide) is measured in blood samples. Bromide is normally present in the blood of all people, but the levels of bromide increase when people are exposed to bromomethane. The amount of increase depends on the level of exposure. Tests for bromide are only useful if done within 1-2 days following exposure, and are not very helpful in predicting if exposed persons will have health effects or how serious the effects will be, because not all people respond to bromomethane the same way. [Pg.12]

Existing Equipment Examine suitability and availability of fixed and mobile fire suppression equipment. Suppression equipment requirements will vary with the types of hazards and configuration of the process units. Some organizations may already have suppression and special needs response equipment (HAZMAT response equipment, command vehicle, ambulance, etc.). Determine what type of suppression equipment will be needed. [Pg.361]

Chromatography also has its own special equipment requirements that vary dependent on the type and scale of the procedure, and the efficiency level desired from the separation. This paper deals predominantly with chromatographic separations as they pertain to large-scale industrial processes and their special needs and considerations. [Pg.170]

Exposure to hexachlorobutadiene can be determined by measuring the chemical or its breakdown products in blood, urine, or fat. These tests are not usually performed in most doctors offices because special equipment is needed. Samples can be collected and sent to special laboratories to determine if you were exposed to hexachlorobutadiene. These tests cannot determine how much of the chemical you were exposed to or if adverse health effects will occur as a result of the exposure. [Pg.16]

Several very sensitive and specific tests can detect carbon tetrachloride in exposed persons. The most convenient way is simply to measure carbon tetrachloride in exhaled air, but carbon tetrachloride can also be measured in blood, fat, or other tissues. Because special equipment is needed, these tests are not routinely performed in doctors offices but your doctor can refer you to where you can obtain such a test. Although these tests can show that a person has been exposed to carbon tetrachloride, the test results cannot be used to reliably predict whether any bad health effects might result. Because carbon tetrachloride leaves the body fairly quickly, these methods are best suited to detecting exposures that have occurred within the last several days. Further information on how carbon tetrachloride can be measured in exposed humans is given in Chapter 6. [Pg.15]

If there is an actual bomb threat, carry out the following procedures First, evacuate the premises. Do not fall into fire drill routines remember, you are vacating to avoid injury stemming from premeditated violence. Leave the building immediately. Take nothing with you. Do not shut down electrical equipment. Keep movement to a minimum. If there are visitors or persons with special needs in the building, make certain they are evacuated. [Pg.304]

The trend toward direct motor fuel use of propane and butane will be accelerated in the near future, particularly if the defense emergency should tend to create an over-all scarcity of petroleum products. Propane and butane can advantageously supply certain special needs, such as those of farm tractors and urban busses, of nonitinerant trucks, and of contractors7 earth-moving equipment. The conventional motor fuel so released can help to take care of increased military needs. [Pg.262]

Generally it is much easier to buy gas standards already prepared and analyzed. Experience here would indicate that these standards be viewed skeptically until credibility has been established for a given source for these standards. Certainly rather specialized equipment is needed to prepare a gas mixture with known concentrations of components, but in some cases this is the only reliable way to obtain standards. This discussion is amplified as follows. [Pg.180]

The radiation chemical technique of tin alkylhalogenide production remains not veiy promising due to economic reasons (special equipment is needed) and rigid safety requirements (additional safety measures against the effect of radiation are necessary). [Pg.404]

Since the earliest days of the investigation of catalysts by XAFS spectroscopy, it has been realized that specialized equipment is needed to make the measurements. The cell designs span a huge range, and even to this... [Pg.400]

A different case is the photoenolization of ortho-hydroxybenzoyl derivatives, as outlined in Fig. 7. Here we see there is practically a total reconversion back to starting material at a very fast rate, leading one to conclude that there is total photostability. The same conclusion would be reached whether one is using either a normal specific analytical (e.g., HPLC) or the simple spectral approach. Special photophysical equipment is needed to observe these very short-lived photo-enol transformations. [Pg.386]
