To find out how many dunks are needed we half the diameter to the radius (43), square that number by multiplying it by itself (43x43=1849) then multiply by 3.14159 (5808.8) now divide by the 100 Sq Ft each dunk covers = 58 dunks to do our pond for 30 days. Wow. The better solution for a large pond is a submersible sump pump on a timer to come on at regular intervals and keep the water aerated and moving. **Q: What is the exact definition regarding cats and dogs safety? What agency states the safety of the product?** A: Here is a bit more info with OSHA's required MSDS. I think the EPA designations are most useful in answering you pet related questions.Material Safety Data SheetProduct Identity (Label Name): Mosquito DunksSection 1Manufacturer's Name: Summit Chemical Company7657 Canton Center DriveBaltimore, MD 21224Telephone Number: (410) 282-5200 / (800) 227-8664Date Prepared: 11/01/98EPA No.: 6218-47Section 2 Hazardous Ingredients/Identity InformationHazardous Components OSHA PEL ACGIH TLV Other LimitsNo hazardous or toxic componentsSection 3 Physical CharacteristicsBoiling Point: N/AMelting Point: NoneSpecific Gravity: Less dense than waterEvaporation Rate: N/AVapor Pressure: N/AVapor Density: N/ASolubility in Water: N/AAppearance: Light brown donut - Shaped disks.Odor: Essentially noneSection 4 Fire and Explosion Hazard DataFlash Point: NoneMethod Used:Flammable Limits:L.E.L.: NoneU.E.L.: NoneExtinguishing Media: Water, conventional fire extinguishersSpecial Fire Fighting Procedures: NoneUnusual Fire and Explosion Hazards: NoneSection 5 Reactivity DataStability: Stable: X Unstable:Conditions to Avoid: Protect briquettes from moisture during storageIncompatibility (Materials to Avoid): Alkaline conditions above pH 9 may denatureproductsHazardous Decomposition Products: NoneHazardous Polymerization: Will not occurConditions to Avoid: NoneSection 6 Health Hazard DataRoute of Entry:Inhalation: NoSkin: NoIngestion: NoHealth Hazards (Acute and Chronic): None knownCarcinogenicity:NTP: NoIARC Monograph: NoOSHA Regulated: NoSigns and Symptoms of Exposure: No exposure hazardMedical Conditions Generally Aggravated by Exposure: None knownEmergency and First Aid Procedures: None requiredSection 7 Precautions for Safe Handling and UseSteps to Be Taken in Case Material is Released or Spilled: Clean up with soap and water.Waste Disposal Method: Conventional trash removaland land fill disposal.Precautions to be Taken in Handling and Storage: Store in a cool dry placeOther Precautions: Reseal opened containers afterpartial use.Section 8 Control MeasureRespiratory Protection (Specify Type): None neededVentilation:Local Exhaust: None neededMechanical: None neededSpecial:Other:Protective Clothing: None needed, wear normal work clothesGloves: None neededEye Protection: None neededClothes: None neededProtective Clothing: No special practices neededCheers. **Q: is this product pet friendly to cats and dogs... ye or no?** A: 100% pet friendly.
