Description of first aid measures
If inhaledMove 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.

Indication of any immediate medical attention and special treatment needed
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. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Poisons A and B
Extinguishing media
Use dry chemical, carbon dioxide or alcohol-resistant foam.

no data available
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
If a spill occurs, clean it up promptly. Don't wash it away. Instead, sprinkle the spill with sawdust, vermiculite, or kitty litter. Sweep it into a plastic garbage bag, and dispose of it as directed on the pesticide product label./Residential uses/
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Do not contaminate water, food or feed by storage or disposal. Bardac Wood Preservative 80

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Bioaccumulative potential
A BCF of 81 was reported in bluegill sunfish (Lepomis macrochirus) for didecyl dimethyl ammonium chloride(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate. Didecyl dimethyl ammonium chloride is reported to have low bioconcentration in tests using carp (Cyprinus carpio)(3); BCF values not reported(SRC).
Mobility in soil
The log Koc for didecyl dimethyl ammonium chloride has been reported as 5.64 (sand), 5.96 (sandy loam), 6.20 (silty clay loam), 6.17 (silt loam)(1), corresponding to Koc values of 4.4X10+5, 9.1X10+5, 1.6X10+6, and 1.5X10+6 respectively(SRC). In batch equilibrium studies using five different soil types and OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method), didecyl dimethyl ammonium chloride had Koc values of 667, 1140, 10456, 14072 and 24433(2). According to a classification scheme(2), these Koc values suggest that didecyl dimethyl ammonium chloride is expected to have low to no mobility in soil with most Koc values suggesting the compound is immobile in soil. Didecyl dimethyl ammounium chloride is a cationic surfactant(1) that may exist in cation form in the environment(SRC), and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Didecyl dimethyl ammounium chloride binds rapidly to suspended solids and sediments(1). Reported Kd values at 25 deg C are 3.03 (sand), 3.91 (sandy loam), 4.52 (silty clay loam), and 4.49 (silt loam)(1).
