Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowed
Rinse mouth. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Inhalation of spray and prolonged or repeated contact with skin should be avoided. (EPA, 1998)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration.

12.2 Persistence and degradability
AEROBIC: In soil, chlormequat chloride is rapidly degraded by microbial activity and has no influence on soil microflora or fauna(1). Half-lives in 4 soils were reported as averaging 32 days at 10°C and 1 to 28 days at 22°C(1). Studies with soil microorganisms indicated that chlormequat chloride breakdown occurred through oxidative processes(2). Chlormequat chloride, at an initial concentration of 282 ppm, biodegraded 18% after running a compost operation consisting of poultry and pig manure for 56 days; the high concentration may have retarded degradation(3). Based on analogy to other quaternary ammonium compounds(4), the reduction of biomass or other nutrient materials in natural water may reduce the biodegradation rate of the chlormequat chloride cation and acclimation enhances biodegradation of quaternary ammonium compounds.
12.3 Bioaccumulative potential
An estimated BCF of 3.2 was calculated for chlormequat chloride(SRC), using a log Kow of -3.80(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).
12.4 Mobility in soil
The Koc of chlormequat chloride has been reported to be 203(1). According to a classification scheme(2), this Koc value suggests that chlormequat chloride is expected to have moderate mobility in soil. However, this compound exists as a quaternary ammonium cation and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(3). Chlormequat chloride is expected to adsorb strongly to various materials, including suspended solids in wastewater treatment facilities, sediments in rivers and lakes, suspended organics and minerals in natural water systems, clays, proteins, and microorganisms(4-6). Further, adsorption of quaternary ammonium compounds to river sediment occurs primarily by an ion-exchange mechanism(5). Monitoring studies of river water samples from Germany reported that 50% of an alkyltrimethyl quaternary ammonium compound detectable in the water column was associated with suspended solids in the water; the suspended solids in the water comprise a small fraction of the water(7).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
