Keep people away from and upwind of spill/leak. Wear equipment and emergency appropriate protective equipment and clothing during clean-up. Do not breathe dust. Use a procedures NIOSH/MSHA approved respirator if there is a risk of exposure to dust/fume at levels exceeding the exposure limits. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Ensure adequate ventilation. Local authorities should be advised if significant spillages cannot be contained. For personal protection, see section 8 of the SDS. Methods and materials for Avoid dispersal of dust in the air (i.e., clearing dust surfaces with compressed air). Minimize dust containment and cleaning up generation and accumulation. Collect dust using a vacuum cleaner equipped with HEPA filter. This material is classified as a water pollutant under the Clean Water Act and should be prevented from contaminating soil or from entering sewage and drainage systems which lead to waterways. Stop the flow of material, if this is without risk. Large Spills: Wet down with water and dike for later disposal. Absorb in vermiculite, dry sand or earth and place into containers. Shovel the material into waste container. Following product recovery, flush area with water. Small Spills: Sweep up or vacuum up spillage and collect in suitable container for disposal. Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to remove residual contamination. Never return spills to original containers for re-use. Put material in suitable, covered, labeled containers. For waste disposal, see section 13 of the SDS. Environmental precautions Avoid release to the environment. Inform appropriate managerial or supervisory personnel of all environmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, water courses or onto the ground. 7. Handling and storage Precautions for safe handling Obtain special instructions before use. Do not handle until all safety precautions have been read and understood. Minimize dust generation and accumulation. Do not breathe dust. Do not taste or swallow. Avoid contact with eyes, skin, and clothing. Avoid prolonged exposure. When using, do not eat, drink or smoke. Should be handled in closed systems, if possible. Use only outdoors or in a well-ventilated area. Wear appropriate personal protective equipment. Wash hands thoroughly after handling. Avoid release to the environment. Observe good industrial hygiene practices. Conditions for safe storage, Store locked up. Store in tightly closed container. Store in a well-ventilated place. Store away from including any incompatibilities incompatible materials (see Section 10 of the SDS). 8.

  • Exposure Data
    BERYLLIUM AND BERYLLIUM eOMPOUNDS Beryllium and beryllium compounds were considered by previous Working Groups, In 1971,1979 and 1987 (lARe, 1972, 1980, 1987a). New data have since become available, and these are included in the present monograph and have been taken into consideration In the evaluation. The agents considered herein Include (a) metallic beryllium, (b) beryllium- aluminium and -copper alloys and (c) some beryllum compounds. 1. Exposure Data 1.1 Chemical and physical data and analysis 1.1.1 Synonyms, trade names and molecular formulae Synonyms, trade names and molecular formulae for beryllium, beryllum-aluminium and -copper alloys and certain beryllium compounds are presented in Thble 1. The list is not exhaustive, nor does it comprise necessarily the most commercially important beryllum- containing substances; rather, it indicates the range of beryllum compounds available. 1. 1.2 Chemical and physical properties of the pure substances Selected chemical and physical properties of beryllium, beryllum-aluminium and -copper alloys and the beryllium compounds covered in this monograph are presented in Thble 2. The French chemist Vauquelin discovered beryllium in 1798 as the oxide, while analysing emerald to prove an analogous composition (Newland, 1984). The metallc element was first isolated in independent experiments by Wöhler (1828) and Bussy (1828), who called it 'glucinium' owing to the sweet taste of its salts; that name is stil used in the French chemical literature. Wöhler's name 'beryllum' was offcially recognized by IUPAe in 1957 (WHO, 1990). The atomic weight and corn mon valence of beryllum were originally the subject of much controversy but were correctly predicted by Mendeleev to be 9 and + 2, respectively (Everest, 1973).
