3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW: Corrosive to skin. Harmful or fatal if swallowed

Routes of Exposure: Contact, ingestion. Target Organ Effects: Eyes: Exposure to particulates or solution of this product may cause redness, pain and blurred vision. Prolonged contact may cause corneal injury. Skin: This product can cause irritation of the skin with pain, itching, and redness. Depending on the duration of skin contact, skin overexposures may cause chemical burns resulting in blistering of skin and possible scarring. Inhalation: May irritate the nose, throat and respiratory tract. Symptoms can include sore throat, coughing and shortness of breath. In severe cases, ulceration and perforation of the nasal septum and upper respiratory tract can occur. In severe cases, pulmonary edema may occur that could potentially lead to death. Ingestion: Harmful if swallowed. May cause gastrointestinal irritation with symptoms such as nausea, vomiting, and diarrhea. Carcinogenicity: Not a carcinogen

4. FIRST AID MEASURES

Eyes: In case of contact with eyes, rinse immediately with plenty of water for at least 20 minutes. Seek medical attention. Skin: Remove all contaminated clothing. For skin contact, wash thoroughly with soap and water for at least 20 minutes. Seek immediate medical attention if irritation develops or persists. Ingestion: DO NOT INDUCE VOMITING. Never give anything by mouth to a victim who is unconscious or having convulsions. Immediately give victim milk (4 to 8 ounces). Contact a physician or poison control center immediately. Inhalation: Remove to fresh air. If breathing has stopped, apply artificial respiration. Get immediate medical attention.

5. FIRE FIGHTING MEASURES

Flash Points: Not flammable. Hazardous Combustion Products: Nitrogen oxides, sulfur oxides, and ammonia. General Hazards: As a solid, Sulfamic acid is not combustible, however as a solution, it is corrosive and presents a severe inhalation and contact hazard to firefighters. When in solution, this material becomes combustible, depending on the concentration of the aqueous solution. When involved in a fire, this material may decompose and produce corrosive and/or toxic gases (i.e. ammonia and sulfur oxides). Extinguishing Media: Dry chemical, foam, carbon dioxide, water fog. Use water to cool fire-exposed containers and to protect personnel. Fire Fighting Instructions: Firefighters should wear full protective clothing including self-contained breathing apparatus. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. Other Information: Autoignition Temperature: Not Applicable, Flammability Limits in Air (% by volume): Not Applicable.

6. ACCIDENTAL RELEASE (SPILL MEASURES)

Containment Procedures: Stop the flow of material, if this is without risk. Contain the discharged material. If sweeping of a contaminated are is necessary use a dust suppressant agent, which does not react with product.

Clean-Up Procedures: Wear appropriate equipment and clothing during clean up. Shovel the material into waste container. Thoroughly wash the area after a spill or release clean up.

7. HANDLING AND STORAGE

Handling: All employees who handle this material should be trained to handle it safely. Do not breathe dust. Avoid all contact with skin and eyes. Use this product only with adequate ventilation. Storage: When not in use keep container closed. Store in a cool dry location.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Engineering Controls: Good general ventilation. Eye Protection: Chemical goggles. Skin Protection: Impervious gloves, boots and coveralls to avoid skin cotact, Respiratory Protection: Use only NIOSH/MSHA approved respiratory protection. Other Protective Equipment: As required to minimize skin contact. Eye wash, safety shower, Exposure Guidelines: The exposure limits given are for Particulates Not Otherwise Classified.

9. PHYSICAL AND CHEMICAL PROPERTIES (Typical)

Softening Point: Not applicable. Appearance and Odor: White crystalline solid, odorless. Bulk Density: Approx. 12 lbs/gal. Solubility in H20: 21.5 g/L (@ 20 deg C) pH (1% solution): approx. 1.2 - 1.18

10. STABILITY AND REACTIVITY

Chemical Stability: Stable when dry, but slowly hydrolyzes in solution. Conditions to Avoid: Avoid dispersion of Sulfamic Acid particulates into air and contact with heat. Avoid the use of non-vented container if concentrated solutions of the acid are made and heated. Hazardous Decomposition Products: Nitrogen oxides, sulfur oxides and ammonia gas. Concentrated solutions, when heated, will release sulfur dioxide and sulfur trioxide. Hazardous Polymerization: Will not occur.

11. TOXICOLOGICAL INFORMATION

General Product Information: Harmful or fatal if swallowed. Product is an eye and skin irritant, and can cause burns. Sulfamic Acid is a respiratory tract irritant, and inhalation may cause nose irritation, sore throat, coughing, and chest tightness and possible, ulceration and perforation of the nasal septum. Inhalation exposure to high levels could cause pulmonary edema, which could result in death. The following data are available regarding corrosivity of this compound. Skin-Human 4%/5 days-intermittent: Mild irritation effects; Skin-Rabbit, adult 500 mg/24 hours: Sever irritation effects; Eye effects-Rabbit, adult 20 mg Moderate irritation effects; Eye effects-Rabbit, adult 250 mg/24 hours: Sever irritation effects. Chronic: Long term skin overexposure to this product may lead to dermatitis and eczema. Prolonged or repeated eye contact may cause conjunctivitis and possibly corneal abnormalities

12. ECOLOGICAL INFORMATION

General Product Information
Harmful to aquatic life in very low concentrations. Sulfamic Acid is toxic to fish and marine organisms when applied to streams, rivers, ponds or lakes.

Ectoxicity
Sulfamic Acid (5329-14-6) - LC50 (Pimephales promelas, fathead minnow) 96 hours = 58.8-84 mg/L, fresh water, 22 deg C

13. DISPOSAL CONSIDERATIONS

Dispose of in an approved waste container. Disposer must comply with local state and federal regulations with respect to disposal or discharge.
