| Fire hazards | Flash point data for this chemical are not availablehowever, it is probably combustible. (NTP, 1992)Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of explosion as a result of decomposition when heated. |
|---|
| Health hazards | SYMPTOMS: Symptoms of exposure to this chemical include eye, skin and mucous membrane irritationburning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, vomiting and methemoglobinemia. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchichemical pneumonitis and pulmonary edema. |

|---|
| Reactivity Profile | A reducing agent. Reacts with bases and oxidizing agents. (NTP, 1992) |
|---|
| Chemical Dangers | Decomposes slowly on contact with moisture. Upon heating, toxic fumes are formed. Decomposes on heating. This generates explosion hazard. The solution in water is a weak acid. Attacks many metals. |
|---|
| Packaging and Labelling | Do not transport with food and feedstuffs. Marine pollutant. |
|---|
| Fire fighting | Fires involving this material can be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)In case of fire in the surroundings, use appropriate extinguishing media. |
|---|
| First aid measures | Fresh air, rest. Refer for medical attention.Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention . |
|---|
| First aid | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
|---|
| Safe storage | Dry. Cool. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. |
|---|
| Nonfire spill response | SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. |
|---|
| Spillage disposal | Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered non-metallic containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. |

| Isolation and Evacuation | Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: |
|---|
| Eye Prevention | Wear safety goggles or eye protection in combination with breathing protection if powder. |
|---|
| Inhalation Risk | Evaporation at 20 °C is negligiblea harmful concentration of airborne particles can, however, be reached quickly when dispersed. |
|---|
| Skin Prevention | Protective gloves. |
|---|
| Exposure Prevention | AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! |
|---|
| Ingestion Prevention | Do not eat, drink, or smoke during work. |
