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.
Specific Hazards Arising from the Chemical
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.
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
Keep container closed. Store in a dry place. Do not store at elevated temperatures. Keep from freezing. Do not reuse empty container. Dantogard XL-1000

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.

Persistence and degradability
AEROBIC: Using OECD Guideline 301 A (new version) (Ready Biodegradability: DOC Die Away Test), 1,3-dimethylol-5,5-dimethylhydantoin was found to be readily biodegradable in activated sludge with 75% degradation in 10 days and 95% degradation in 28 days(1). The degradation product of 1,3-dimethylol-5,5-dimethylhydantoin, 5,5-dimethylhydantoin, was found to be readily biodegradable via OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test) with 87% CO2 evolution within 28 days of incubation and >60% degradation in 10 days(1). 5,5-Dimethylhydantoin was steadily biodegraded using OECD Guideline 308 (Aerobic and Anaerobic Transformation in Aquatic Sediment Systems) with half-lives of 13-24 days(1).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for 1,3-dimethylol-5,5-dimethylhydantoin(SRC), using a log Kow of -2.9(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Dimethylhydantoin (DMT), a degradation product of 1,3-dimethylol-5,5-dimethylhydantoin, has a BCF of 0.08(1).
Mobility in soil
Using OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)), the Koc of 1,3-dimethylol-5,5-dimethylhydantoin was determined to be <17.8(1). According to a classification scheme(2), this estimated Koc value suggests that 1,3-dimethylol-5,5-dimethylhydantoin is expected to have very high mobility in soil.

Disposal methods
ProductThe 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.
