FLAGGING

or traverse numbers, may also be painted on. For a neater job, stencils are sometimes used. FLAGGING Colored cloth bunting or plastic tape is often used to make stakes conspicuous so they will be easier to find or to warn Equipment Operators away. Flagging may also be used for identification purposes. For example, traverse stakes may be marked with one color, grade stakes with another. Red, yellow, orange, and white are the most popular colors of flagging. NOTE-KEEPING MATERIALS Field notes are usually kept in a bound, standard field notebook. Sometimes loose-leaf notebooks are used but are not generally recom- mended because of the chance of losing some pages. Notebooks are classified as ENGINEER’S or TRANSIT FIELD BOOKS, LEVEL BOOKS, CROSS SECTION BOOKS, and so forth, depending on their use. In a transit book, the left-hand side of the page is used for recording measurement data, and the right-hand side of the page, for remarks, sketches, and other supplementary information. The other field books generally follow the same pattern of usage. Different types of field books and inside pages are shown in figure 11-58. Note how each type is lined or gridded. Actually, a transit or a level book may be used for recording any type of survey. You may add or modify the column headings to suit the required data you desire to record. PERSONAL PROTECTIVE AND SAFETY EQUIPMENT In addition to the necessary field supplies and equipment, a field party must carry all necessary items of personal protective equipment, such as containers for drinking water, first-aid kits, gloves, and foul weather gear, as needed. A field survey party is usually working a considerable distance away from the main operational base. If, for example, you happen to be chaining through a marsh filled with icy water, you would not have a chance to return to the base to get your rubber boots. You are required to wear a hard hat whenever you work in a construction area where the Figure 11-58.-Diffferent types of field books. assigned personnel are regularly required to wear hard hats. Do NOT get caught-flat-footed in any situation. To avoid this, you should study the situation in advance—considering both the physical and environmental conditions. 11-49
