C depending on the reference consulted). Fires may be controlled with carbon dioxide or dry chemical extinguishers. Recommended methods of handlings loadings unloadings and storage can be obtained from Material Safety Data Sheets and inquiries directed to suppHers of acetone. 

Fig. 5. Equipment foi surface treating plastic components. Parts ate loaded into one of the two lower chambers which is then evacuated to remove most of the air. This chamber is then flooded with a dilute mixture of fluorine and nitrogen which is made and stored in the upper chamber. After the treatment is completed, the fluorine mixture is pumped back up to the upper chamber for storage and the lower chamber repeatedly flooded with air and evacuated to remove any traces of fluorine gas. Two treatment chambers are cycled between the loading/unloading operation and the treatment step to increase equipment output. The fluorine—nitrogen blend may be used several times before by-products from the treatment process begin to interfere. AH waste...

D. Loading, Unloading and Transfer Areas (for raw materials and wastes)... 

In order to maintain a high level of quality and safety in the actual operations, whether chemicals are transferred, loaded/unloaded or transported, proper operating instructions/procedures are crucial and should be regularly reviewed.

Communication should be established and maintained between people on the ship, the berth and at the storage installation during loading/unloading.

These mirror those at fixed installations, but loss of eontainment due to the triggering event ean oeeur anywhere en route. Thus aeeidents may oeeur in populated or environmentally sensitive loeations, or where domino effeets are less easily eontrolled. Common risks are also assoeiated with all vehieular movements and meehanieal/manual loading/unloading aetivities. 

A basie safety audit eovering design and system of work features to be eovered for the loading/ unloading of non-pressurized hazardous liquids to/from tankers of tank eontainers is given in Table 15.18.

Tests have shown that when total strain is plotted against the logarithm of the total creep time (ie NT or total experimental time minus the recovery time) there is a linear relationship. This straight line includes the strain at the end of the first creep period and thus one calculation, for say the 10th cycle allows the line to be drawn. The total creep strain under intermittent loading can then be estimated for any combinations of loading/unloading times. 

Tankcar, tankwagon, and hopper car loading, unloading, and cleaning. 

It is not always possible to keep the trailer connected to the truck s unit during loading/unloading. If it is not connected, the front compartments should be filled last and emptied first or a support put under the front of the trailer. 

The Hazardous Materials Transportation Act (HMTA) defines transportation releases to be those that occur during loading, unloading, transportation or temporary storage of hazardous materials or waste. Releases that meet certain criteria (see Table 64.1) should be reported to the National Response Center (NRC) and the state response center. Most states also require calls to the local police or response agencies (often by calling 911). Follow-up writ-...
