Becoming Familiar with the Rule

OSHA has provided a simple summary of the HCS in a pamphlet entitled Chemical Hazard Communication, OSHA Publication No. 3084. Some employers prefer to begin to familiarize themselves with the rule s requirements by reading this pamphlet. A copy may be obtained from your local OSHA Area Office, by contacting the OSHA Publications Office at (202) 693-1888 or via the OSHA Web site under publications or search by title. 

The HCS requires information to be prepared and transmitted regarding all hazardous chanicals. The HCS covers both physical hazards (such as flammability) and health hazards (such as irritation, lung damage, and cancer). Most chanicals used in the workplace have some hazard potential, and thus will be covered by the rule. 

One difference between this rule and many others adopted by OSHA is that this one is performance oriented. This means that you have the flexibility to adapt the rule to the needs of your workplace. 

The standard s design is simple. Chemical manufacturers and importers must evaluate the hazards of the chemicals they produce or import. Using that information, they must then prepare labels for containers, and more detailed technical bulletins called MSDSs. 

Chemical manufacturers, importers, and distributors of hazardous chemicals are all required to provide the appropriate labels and MSDSs to the employers to whom they ship the chemicals. This information should be provided automatically. Every container of hazardous chemicals you receive must be labeled, tagged, or marked with the required information. Your suppliers must also send you a properly completed MSDS at the time of the first shipment of the chemical and with the next shipment after the MSDS is updated with new and significant information about the hazards. You can rely on the information received from your suppliers. You have no duty to analyze the chemical or evaluate its hazards.

Because both formats are now well established, Member States and potential bidders would be - or could easily become - familiar with the rules of either auction. Using these familiar formats would also address concerns about auctions being untested or over-complicated. Both discriminatory and uniform-price formats would be feasible and low-cost for Member States.26... 

The user of indexes must become familiar with the rules of nomenclature and the history of their development. 

In this introductory chapter you have encountered some of the basic manipulations of Excel. The first time around you may feel overwhelmed by it, but don t worry as you practice, you will quickly become familiar with the rules of spreadsheets, and with their internal logic. A spreadsheet not only allows you to perform repeated calculations (such as computing values for a sine wave) and to print them as a graph, but to perform many much more sophisticated operations, such as data analysis and mathematical simulation. The main attributes of a spreadsheet such as Excel are ... 

It is essential for the plant engineer to become familiar with the rules of the Code and also with other publications of the National Fire Protection Association that further define the steps which can reduce the hazards. 

Become familiar with the principles of safe writing rules as suggested by the Institute of Safe Medication Practice... 

In an Excel spreadsheet, the [TRANSPOSE function can be applied to an array of data. For this, we need to become familiar with the two most important rules to perform matrix operations in Excel ... 

When submitting a sample for NMR analysis (measured either automatically or manually) you usually have access to the plotted spectrum and sometimes the raw spectral data (FID). Although it is not necessary to process the data yourself, there are a number of important reasons why you should become familiar with the basic principles and rules of NMR data processing. Generally data processing is applied ... 

Let us first become familiar with the spin-free (sf) case we have a pair of Slater determinants interacting via (i.e., a sum of spin-independent one-and two-electron operators, h and 12). Their matrix element is given by (Sla-ter-Condon rules) ... 

Shortly you will be introduced to the rules for writing proper Lewis structures. Here we simply want to become familiar with the language associated with them. 

Whether you ve ever done Lewis structures before or not. follow the rules in Section 1-4 very closely. Become familiar with the number of electrons around common atoms and the common arrangements of thc.se electrons in the bonds of molecules. This familiarity, brought about by iloing luf.s of ex.implc.s, i.s the... 

As health hazard information for ethylene oxide is currently an area for active research, users of ethylene oxide are urged to become familiar with the most current data, rules, and regulations. As an absolute minimum, the user should have and be conversant with the latest version of the MSDS available from their product supplier, and the OSHA regulations in 29 CFR 1910.1047, Occupation Exposure to Ethylene Oxide, Final Standard [4]. 

As we explore working with lead in the following pages, you will become familiar with the types of rulings to expect as a lead contractor. 

Testing, certification, and installation rules for reheving devices are extensive. Eveiy chemical engineer responsible for the design or operation of process units should become veiy familiar with these rules. The pressure-relief-device paragraphs are the only parts of Sec. TII, Division I, that are concerned with the installation and ongoing operation of the facility all other rules apply only to the design and manufacture of the vessel. 

Vessel Codes Other Than ASME Different design and construction rules are used in other countries. Chemical engineers concerned with pressure vessels outside the United States must become familiar with local pressure-vessel laws and regulations. Boilers and Pressure Vessels, an international survey of design and approval requirements published by the British Standards Institution, May-lands Avenue, Hemel Hempstead, Hertfordshire, England, in 1975, gives pertinent information for 76 political jurisdic tions. 

Older laboratory workers could no doubt add many examples of their own to the list of unsafe practices. Modern laboratory planners and operators, however, are more aware of safety problems, and rules regarding safety have been made much more strict. It is up to the laboratory operator to become throughly familiar with such rules in order to organize and operate a safe laboratory. 

The modern theory of the electronic structure of the atom is based on experimental observations of the interaction of electricity with matter, studies of electron beams (cathode rays), studies of radioactivity, studies of the distribution of the energy emitted by hot solids, and smdies of the wavelengths of light emitted by incandescent gases. A complete discussion of the experimental evidence for the modern theory of atomic structure is beyond the scope of this book. In this chapter only the results of the theoretical treatment will be described. These results will have to be memorized as rules of the game, but they will be used so extensively throughout the general chemistry course that the notation used will soon become familiar. In the rest of this course, the elementary theory presented in Chap. 3 will suffice. You should study only those parts of this chapter that are covered in your course. 

Palladium-catalysed processes typically utilise only 1-5 mol% of the catalyst and proceed through small concentrations of transient palladium species there is a sequence of steps, each with an organopalladium intermediate, and it is important to become familiar with these basic organopalladium processes in order to rationalise the overall conversion. Concerted, rather than ionic, mechanisms are the rule, so it is misleading to compare them too closely with apparently similar classical organic mechanisms, however curly arrows can be used as a memory aid (in the same way as one may use them for cycloaddition reactions), and this is the way in which palladium-catalysed reactions are explained in the following discussion. (For convenience, an organometallic component can be referred to as the nucleophilic partner and the halide as the electrophilic partner, but this should not necessarily be taken to imply reactivity as defined in classical chemistry. Also, references to the halide should be understood to include all related substrates, such as triflates.)...
