SECTION 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Toxic by inhalation and if swallowed. Danger of cumulative effects. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful amounts. Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath,
Ingestion:
May be fatal if swallowed. Poison by ingestion. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause liver and kidney damage. May cause cardiac abnormalities.
Inhalation:
Causes respiratory tract irritation. Irritation may lead to chemical pneumonitis and pulmonary edema. Inhalation of fumes may cause metal fume fever, which is characterized by flu-like symptoms with metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white blood cell count.
Chronic:
May cause reproductive and fetal effects. Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath, Laboratory experiments have resulted in mutagenic effects.

SECTION 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.

SECTION 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.
Storage:
Store in a cool, dry place. Keep container closed when not in use.

---

SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:

Spain: (listed as selenium compounds): 0.1 mg/m3 VLA-ED (except hydrogen selenide, as Se) Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.

制备方法与用途

制备方法

1.可由硒酸与氢化钠作用而制得。2.生成硒酸钠的反应方程式有.将亚硒酸钠在空气中于700～725℃加热，亚硒酸钠即转化为硒酸钠。另外将准确称量的干燥的碳酸钠与二氧化硒按等物质量混合，或者用干燥的碳酸钠与元素硒按等物质量混合，在空气中慢慢加热这种混合物使温度升到700～725℃也可制得硒酸钠。3.用硒酸与碳酸钠反应即可制得硒酸钠.将125g Na2CO3分次慢慢地加入到含181g H2SeO4的溶液中，碳酸钠溶解完之后(必要时过滤)，将所得的溶液尽量加热浓缩，直至有相当大量的沉淀生成。若此时出现微弱的红色或棕色(由于溶解的胶体硒所致)，则应再用水稀释，煮沸并放置1～2h后过滤。随后再蒸发。趁热吸滤，使Na2SeO4晶体在温度不低于45℃的情况下与母液分离。将结晶夹在两层滤纸中间挤压使其干燥。
