Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool . Cover skin burns with dry sterile dressings after decontamination . Poisons A and B
SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

SECTION 10: Stability and reactivity
Reactivity
Insoluble in water. Reacts slowly with water. The reaction is promoted by acid such that the pH is less than 5.0 (1/2 life of 24-48 hrs.). Reaction is also promoted by polar organic solvents such as methanol and acetone.
Chemical stability
Stable to light when dry. ... In aqueous solutions, 50% hydrolysis occurs 4-8 weeks @ pH 5.7-7.0 and 20 deg C. Significant degradation occurs in 24-48 hr in acidic aqueous solutions below pH 5. Hydrolysis is also promoted by polar organic solvents such as methanol and acetone.

Persistence and degradability
AEROBIC: Pure cultures of microorganisms and mixed microorganisms in soil degraded chlorsulfuron(1). The half-lives of chlorsulfuron in two non-sterile soils were 5 days and 15 days at 30 deg C compared to the half-lives of 21 days and 28 days, respectively, in the sterile soils(1). Microbial breakdown accounted for 79% of the total initial degradation in a silt loam soil (pH 5.9, organic matter 5%), 50% in a sandy loam soil (pH 6.5, organic matter 1%) and 91% in a silt loam soil (pH 8.0, organic matter 5%)(1). On the other hand, microbial breakdown accounted for only 25% of total loss in a silty clay loam soil (pH 5.6, organic matter 2.4%)(2).
Bioaccumulative potential
An estimated BCF of 3 was calculated for chlorsulfuron(SRC), using a log Kow of -1.34(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The soil adsorption coefficient Kd of chlorsulfuron in sandy soil (88% sand,4% silt, 7.2% clay, 0.6% organic matter, pH 6.5), sandy clay (71.1% sand,8.6% silt, 20.3% clay,1.1% organic matter, pH 7.5), and a clay soil (19.2% sand,26.2% silt, 54.6% clay,1.5% organic matter, pH 7.6) was 0.170, 0.295, and 0.99, respectively(1). Using the percentage of organic carbon in each soil, these adsorption coefficients correspond to Koc values of 47, 45, and 110 in the sandy soil, sandy clay, and clay soil, respectively. Based on experimental soil adsorption coefficient's, the Koc values for chlorsulfuron in soil have been estimated to be in the range 6-31 in the soil pH range 6.2-8.1(2-5). According to a classification scheme(6), these Koc values suggests that chlorsulfuron is expected to have high to very high mobility in soil(SRC).
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
