Immediately flush eyes with plenty of water for at least 15 minutes. Then get immediate medical attention. 

Never make an unconscious person vomit or drink fluids. Give large amounts of water. DO NOT induce vomiting. If vomiting occurs, keep head lower than hips to help prevent aspiration. If person is unconscious, turn head to side. Get medical attention immediately. 

For inhalation, consider oxygen. 

See Section 9 for Flammability Properties 

Slight fire hazard. Dust/air mixtures may ignite or explode. 

regular dry chemical, carbon dioxide, water, regular foam 

Large fires: Use regular foam or flood with fine water spray. 

Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. Use extinguishing agents appropriate for surrounding fire. Do not get water directly on material. Large fires: Flood with fine water spray. Reduce vapors with water spray. Cool containers with water spray until well after the fire is out. Apply water from a protected location or from a safe distance. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. 

Collect spilled material in appropriate container for disposal. Keep out of water supplies and sewers. Keep unnecessary people away, isolate hazard area and deny entry. 

Store and handle in accordance with all current regulations and standards. Store in a cool, dry place. Store in a tightly closed container. Keep separated from incompatible substances. 

Component Exposure Limits 

Biological limit value 

Based on available information, additional ventilation is not required. Ensure compliance with applicable exposure limits. 

Eyes/Face Wear splash resistant safety goggles with a faceshield. Provide an emergency eye wash fountain and quick drench shower in the immediate work area. 

Wear appropriate chemical resistant clothing. 

Wear appropriate chemical resistant gloves. 

rubber 

No respirator is required under normal conditions of use. Under conditions of frequent use or heavy exposure, respiratory protection may be needed. For Unknown Concentrations or Immediately Dangerous to Life or Health - Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode. Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. 

Stable at normal temperatures and pressure. 

Avoid heat, flames, sparks and other sources of ignition. Dangerous gases may accumulate in confined spaces. May ignite or explode on contact with combustible materials. 

bases, halogens, oxidizing materials 

STARCH ACID ALKALIS (STRONG): Incompatible. STARCH OXIDIZERS (STRONG): Fire and explosion hazard. SULFAMIC ACID BASES: Violent reaction. BROMINE GAS: Oxidizes to sulfuric acid and nitrogen gas. CHLORINE: Formation of a very sensitive, explosive nitrogen trichloride. METAL NITRATES + NITRITES: Heating may result in a violent reaction. NITRIC ACID: Fuming nitric acid combined with sulfamic acid causes violent release of nitrous oxide. OXIDIZERS: Fire and explosion hazard. POTASSIUM CHLORATE: Oxidizes to sulfuric acid and nitrogen gas.

oxides of sulfur 

Thermal decomposition products: oxides of sulfur. 

Will not polymerize. 

Component Analysis - LD50/LC50 

Component Carcinogenicity

respiratory disorders 

SULFAMIC ACID: Inhalation of fumes or mist from acids may cause coughing, choking, headache, dizziness, weakness, hypotension, and delayed pulmonary edema with chest tightness, apnea, frothy sputum, and cyanosis Dyspnea and hemoptysis are possible for several weeks after exposure After inhalation of corrosive atmospheres, convalescence may be prolonged and frequent relapses may occur STARCH: High concentrations may cause unpleasant deposits in the nasal passages.

SULFAMIC ACID: Repeated or prolonged exposure to acidic fumes may cause erosion of teeth followed by jaw necrosis Bronchial irritation with cough and frequent attacks of bronchial pneumonia may occur Gastrointestinal disturbances are also possible STARCH: Repeated or prolonged exposure may possibly cause chemical pneumonitis.

STARCH ACID (Garratt-Callahan Co. has reported the following): Airborne dust is corrosive Inhalation of dust can result in irritation or destruction of respiratory tissues.

SULFAMIC ACID: Direct contact with acids may cause severe pain, burns and stains Extensive scarring may occur from the burns penetrating deep into the skin layers requiring a long period to heal Concentrations of greater than 20% of sulfamic acid may injure the skin STARCH: High concentrations may cause unpleasant deposits on the skin Injury may occur by chemical or mechanical action or by rigorous skin cleansing procedures necessary for removal of the dust.

SULFAMIC ACID: Repeated application of a 4% solution of sulfamic acid several times a day for 5 days on the skin of 5 human subjects produced mild irritation STARCH: Repeated and prolonged contact may cause mild irritation Dermatitis has been reported in workers handling starch products Starch is metabolized by microorganisms on the skin which may result in overgrowth of candida Starch dust has been reported to have slight allergenic properties.

STARCH ACID (Garratt-Callahan Co. has reported the following) May cause irritation.

SULFAMIC ACID: Contact with dilute acids will cause immediate pain, conjunctival hyperemia and sometimes injury of the corneal epithelium with symptoms of pain, tearing, and photophobia Usually the corneal epithelium will regenerate promptly and without any corneal opacities Contact with concentrated acids may cause extensive necrosis of the conjunctiva and corneal epithelium with possible penetration and damage to the stroma of the cornea Corneal damage frequently results in blindness The instillation of 0.5 cc of a 4 per cent solution with a pH of 0.82 into the conjunctival sac of 5 rabbits produced a moderate degree of conjunctivitis and edema Substances with a pH of less than 2.0 are considered corrosive to the eyes STARCH: High concentrations may cause irritation and unpleasant deposits in the eyes and seriously reduce visibility Instillation into the anterior chamber of rabbit eyes produced granulomatous reactions.

SULFAMIC ACID: Prolonged or repeated exposure to the dust or mists may cause effects as described in acute exposure STARCH: No data available.

STARCH ACID (Garratt-Callahan Co. has reported the following) Will cause irritation.

SULFAMIC ACID: Ingestion of acids may cause severe burning pain in the mouth, pharynx, and abdomen, followed by vomiting, diarrhea of dark precipitated blood and a drop in the blood pressure Discoloration may be found around the mouth and throat Asphyxia may occur from edema of the glottis After initial recovery, onset of fever indicates mediastinitis or peritonitis from perforation of the esophagus or stomach The patient may have a rigid abdomen without perforation If the patient recovers, scar formation is more apt to produce stricture of the pylorus than stricture of the esophagus Ingestion of greater than 10% of sulfamic acid solutions will cause lesions of the stomach STARCH: Oral administration to rats at a level of 10-20% of their total body weight caused only minimal symptoms.

SULFAMIC ACID: Chronic ingestion of a 2% concentration in the diet of rats for 105 days produced a decline in the growth rate; a 1% concentration in the diet did not produced any adverse effects STARCH: Repeated or prolonged ingestion of very large doses may cause partial intestinal obstruction, iron deficiency anemia, reduced cholesterol, and possibly hypertrophy of the parotid glands.

STARCH ACID (Garratt-Callahan Co. has reported the following): May irritate or burn mouth, throat, and stomach May cause serious damage to mouth, throat, and stomach.
