Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)|In case of fire in the surroundings, use appropriate extinguishing media.

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

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. STORAGE PRECAUTIONS: You should store this chemical under ambient temperatures, and protect it from moisture. If possible, it would be prudent to store this compound under inert atmosphere. (NTP, 1992)

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

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 containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Store and dispose of according to local regulations.

Dry. Well closed. Store in an area without drain or sewer access.

Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

The substance is irritating to the eyes.

The substance may have effects on the central nervous system. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

PREVENT DISPERSION OF DUST!

Use local exhaust or breathing protection.

Protective gloves.

Wear safety spectacles or eye protection in combination with breathing protection if powder.

moderately toxic

SYMPTOMS: Symptoms of exposure to this compound include mild irritation of the eyes and mucous membranes of the respiratory tract. Symptoms of exposure to this type of compound include apathy, anorexia, headache, recurring leg cramps, loss of balance, clumsiness, pneumonia and associated pulmonary problems. Other symptoms include central nervous system damage, pulmonary system damage, upper respiratory infections, languor, sleepiness, weakness in the legs, a stolid, mask-like face, muscular twitchings, varying from a fine tremor of the hands to coarse, rhythmical movements of the arms, legs and trunk; slight increase in tendon reflexes, ankle and patellar clonus, typical Parkinsonian slapping gait and minute handwriting (affected by micrographia). It can cause spastic gait, insomnia, dystonia, fatiguability, asthenia and an inability to concentrate. It can also cause impaired mentation, ataxia, difficulty in walking and decreased movement of the eyelids and eyes. Other symptoms include lethargy, edema, extrapyramidal effects, sleep disturbances, dermatitis, irritability, liver enlargement, increased muscle tone, muscular cramps, mental deterioration, excessive salivation and perspiration, sexual disturbances, blood changes and, very rarely, hypothyroidism. Exposure can cause spasms, arthralgias and speech disturbances such as slurred speech, slow and monotonous voice tone, inability to speak above a whisper, difficult articulation and incoherence, and even complete muteness. Psychosis may occur with unaccountable laughter, euphoria, impulsive acts, absentmindedness, mental confusion, aggressiveness and hallucinations. Propulsion, retropropulsion and lateropropulsion are affected with no movement for protection when falling. Absolute detachment may occur, broken by sporadic or spasmodic laughter. Inhalation may cause acute bronchitis, nasopharyngitis and itching. Numbness of the extremities and impairment of libido may occur. Other effects include weakness, delusions, compulsions, rigidity, bradykinesia, sudden crying, stuttering, hoarse voice, nervousness, inability to walk backward, hyporeflexia, Romberg's sign, adiadochokinesia, forgetfulness, general malaise, drowsiness, stiffness of the arms or legs, urinary difficulty, somnolence, sexual excitement followed by impotence, "hen's gait" and frequent falling. Fever may occur, with chills, upset stomach (nausea), vomiting, dryness of the throat, cough and body aches. Other symptoms include trouble with memory and judgment, unstable emotions, incoordination, chest pain, restlessness, double vision, impaired hearing, anemia, lassitude and low back pain. Symptoms of exposure may simulate progressive bulbar paralysis, post-encephalitic Parkinsonism, multiple sclerosis, amyotrophic lateral sclerosis and progressive lenticular degeneration (Wilson's Disease). ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of sulfur oxides. (NTP, 1992)

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. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

Fresh air, rest.

Rinse with plenty of water for several minutes (remove contact lenses if easily possible).
