Introduction: Ferric sulfate (iron sulfate) is the ferric salt of sulfate. It can be used as a mordant in dyeing and used as a coagulant for the treatment of industrial wastes. In the medical field, it can be used as an astringent and styptic. It is a kind of hemostatic agent being capable of controlling or stopping the flow of blood. It is also recommended that ferric sulfate is a good pulpotomy agent in primary teeth with good potential of substituting the formocresol. It can also be used in pigment, and in pickling baths for aluminum and steel. It is generally prepared through the reaction between ferrous sulfate, sulfuric acid and an oxidizing agent such as nitric acid. View more+

4.1 Exposure Standards and Regulations: The Approved Drug Products with Therapeutic Equivalence Evaluations List identifies currently marketed prescription drug products, incl iron dextran, approved on the basis of safety and effectiveness by FDA under sections 505 of the Federal Food, Drug, and Cosmetic Act.
Oral dosage form new animal drug: iron dextran oral suspension. ... Indications for use: Prevention of iron deficiency anemia in baby pigs. ... Limitations: Treat each pig within 24 hours of farrowing. Administer 1.8 milliliters orally by automatic dose dispenser.
Implantation or injectable dosage form new animal drugs. Iron dextran complex injection. ... Used in baby pigs ... for the prevention of anemia due to iron deficiency... /and/ for the treatment of anemia due to iron deficiency.
Dextrans used as a general purpose food additive in animal drugs, feeds, and related products is generally recognized as safe when used in accordance with good manufacturing or feeding practice. /Dextrans of average molecular weight below 100,000/

4.2 Other Preventative Measures: SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
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. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
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.
PRECAUTIONS FOR "CARCINOGENS": Smoking, drinking, eating, storage of food or of food & beverage containers or utensils, & the application of cosmetics should be prohibited in any laboratory. All personnel should remove gloves, if worn, after completion of procedures in which carcinogens have been used. They should ... wash ... hands, preferably using dispensers of liq detergent, & rinse ... thoroughly. Consideration should be given to appropriate methods for cleaning the skin, depending on nature of the contaminant. No standard procedure can be recommended, but the use of organic solvents should be avoided. Safety pipettes should be used for all pipetting. /Chemical Carcinogens/

If chem will be exhaled, animals should be kept under hood during this period. Inhalation exposure requires special equipment. ... unless specifically required, routes of admin other than in the diet should be used. Mixing of carcinogen in diet should be carried out in sealed mixers under fume hood, from which the exhaust is fitted with an efficient particulate filter. Techniques for cleaning mixer & hood should be devised before expt begun. When mixing diets, special protective clothing &, possibly, respirators may be required. /Chemical Carcinogens/
PRECAUTIONS FOR "CARCINOGENS": When ... admin in diet or applied to skin, animals should be kept in cages with solid bottoms & sides & fitted with a filter top. When volatile carcinogens are given, filter tops should not be used. Cages which have been used to house animals that received carcinogens should be decontaminated. Cage-cleaning facilities should be installed in area in which carcinogens are being used, to avoid moving of ... contaminated /cages/. It is difficult to ensure that cages are decontaminated, & monitoring methods are necessary. Situations may exist in which the use of disposable cages should be recommended, depending on type & amt of carcinogen & efficiency with which it can be removed. /Chemical Carcinogens/

Particular care should be taken to avoid contamination of drains or ventilation ducts. In cleaning labs, procedures should be used which do not produce aerosols or dispersal of dust, ie, wet mop or vacuum cleaner equipped with high-efficiency particulate filter on exhaust, which are avail commercially, should be used. Sweeping, brushing & use of dry dusters or mops should be prohibited. Grossly contaminated cleaning materials should not be re-used ...

6.2 Description: §184.1307(a) Ferric sulfate (iron(HI)sulfate, Fe2(S04)3), a yellow substance that may be prepared by oxidizing iron(II)sulfate or by treating ferric oxide or ferric hydroxide with sulfuric acid.

6.3 Physical properties: The anhydrous salt constitutes grayish-white rhombic crystals; hygroscopic; density 3.10 g/cm³; slightly soluble in cold water; decomposes in hot water. The nonahydrate is a yellow hexagonal crystalline substance; refractive index 1.54; density 2.10 g/cm³; hardness 2.5 Mohs; decomposes at 400°C; very soluble in water.

6.4 Uses: Iron(III) Sulfate can be used for water treatment system.

6.5 Preparation: Iron(III) sulfate may be prepared by oxidation of iron(II) sulfate by hydrogen peroxide, nitric acid or any other suitable oxidizing agent. The reaction is carried out in sulfuric acid. Balanced molecular equations for the reactions with hydrogen peroxide and nitric acid are as follows:
2FeSO₄ + H₂SO₄ + H₂O₂ → Fe₂(SO₄)₃ + 2H₂O
6FeSO₄ + 3H₂SO₄ + 2HNO₃ → 3Fe₂(SO₄)₃ + 2NO + 4H₂O
Even in the absence of an oxidizing agent, concentrated sulfuric acid alone can1 convert iron(II) sulfate to iron(III) sulfate: 2FeSO₄ + 2H₂SO₄→ Fe₂(SO₄)₃ + SO₂ + 2H₂O It also may be prepared by treating iron(III) oxide with sulfuric acid:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
