4. Safety and Handling

4.1 Safety Statements: Poison by intraperitoneal route. A radioactive material. See also URANIUM.

4.1 Packing Group: III

4.1 Other Preventative Measures: SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
The worker should immediately wash the skin when it becomes contaminated. /Uranium (soluble compounds, as U)/
The worker should wash daily at the end of each work shift, and prior to eating, drinking, smoking, etc. /Uranium (soluble compounds, as U)/
Work clothing that becomes wet or significantly contaminated should be removed and replaced. /Uranium (soluble compounds, as U)/
Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises. /Uranium (soluble compounds, as U)/
Standard laboratory measures against chemical poisoning by uranium are mandatory, eg, no pipetting by mouth, no smoking or eating in the laboratory; protective clothing; surgical gloves; and in operations involving dust formation, face masks, constant ventilation of working areas, and glove boxes. /Uranium and cmpd/

4.2 Hazard Class: 7

4.2 Cleanup Methods: 1. Ventilate area of spill. 2. Collect spilled material in the most convenient and safe manner and deposit in sealed containers for reclamation ... Liquid containing soluble uranium compound should be absorbed in vermiculite, dry sand, earth, or similar material. /Soluble and insoluble uranium compound, as uranium/

4.3 DisposalMethods: SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
Disposal of ... wastes /containing uranium/ should follow guidelines set forth by the Nuclear Regulatory Commission. /Uranium & cmpd/

4.4 FirePotential: Finely divided U metal and some U compounds may ignite spontaneously in air or oxygen. /Uranium compounds/

4.5 Safety Profile: Poison byintraperitoneal route. A radoactive material.See also URANIUM. URANYL ACETATESupplier

4.6 Formulations/Preparations: Grades of Purity: Commercial; Reagent /Dihydrate/
Grades of purity: ACS purity

4.7 Protective Equipment and Clothing: Wear appropriate personal protective clothing to prevent skin contact. /Uranium (soluble compounds, as U)/
Wear appropriate eye protection to prevent eye contact. /Uranium (soluble compounds, as U)/
Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. (Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.) /Uranium (soluble compounds, as U)/
Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. /Uranium (soluble compounds, as U)/
Respirator Recommendations: At concentrations above the NIOSH REL, or where there is no REL, at any detectable concentration: (Assigned Protection Factor = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. (Assigned Protection Factor = 10,000) Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus. /Uranium (soluble compounds, as U)/
Respirator Recommendations: Escape(Non-halides): (Assigned Protection Factor=50) Any air-purifying, full-facepiece respirator with an N100, R100, or P100 filter./Any appropriate escape-type, self-contained breathing apparatus. /Uranium (soluble compounds, as U)/

4.8 Report: Reported in EPA TSCA Inventory.

4.9 Skin, Eye, and Respiratory Irritations: Dust: Irritating to eyes, nose, and throat. Solid: Irritating to skin and eyes. /Uranyl acetate dihydrate/

4.11 Specification: Uranium Oxyacetate (CAS NO.541-09-3) is a yellow crystals with a slight odor of vinegar. It can soluble in water and reacting to give a milky solution. The reaction is not hazardous. It reacts weakly as an acid. Usually does not react as either oxidizing agents or reducing agents but such behavior is not impossible. May catalyze organic reactions. Inhalation of dust may irritate nose and throat. Contact with eyes causes irritation.
