Pesticide Packaging, Transportation, and Storage:Hazards and Precautions
Transcript of Pesticide Packaging, Transportation, and Storage:Hazards and Precautions
and Storage:Hazards and Precautions By Rudolf Fischbach For Colloquium: Pesticide Impact 11/14/2012 Transportation: Why is it important? It is a crucial part of the supply chain of pesticides and food. Maintain the quality and quantity of food produced. Pesticides may be considered hazardous materials by department of transportation, they must be transported safely for public and environmental health. Transportation The Department of Transportation and the EPA both share responsibility in regulating transportation of pesticides Hazardous Material Transportation Uniform Safety Act, requires that pesticides being shipped are properly packaged, marked, and labeled. If the pesticide to be shipped is considered a hazardous material (by the DOT), it will need to bear the proper DOT Hazard Warning Labels on the product labeling. Transportation (cont.) A hazardous material may bear labels based on their class. There are 9 classes. Class 1: Explosives Class 2: Gasses Class 3: Flammable/Combustible Liquid Class 4: Solids (Flammable/Combustible, Dangerous when wet) Class 5: Oxidizers, Organic Peroxides Class 6: Poison/Toxic, Poison Inhalation Hazard Class 7: Radioactive Class 8: Corrosive Class 9: Misc. Transportation (cont.) Vehicles carrying hazardous materials are required to carry shipping papers (with class and ID#). Must have placards displayed on all sides of vehicle. This information is used to report accidents which are extremely important in risk assessment. Transportation (cont.) ID Number Class Number Transporters Transporters are required to have knowledge so they can react to chemical spills. Know how to clean up and/or protect the safety of others. Training is required by the DOT for those who transport, send, receive, handle, packages, and loads the materials. Training General Awareness Training MSDS, regulations, labels, and shipping forms Function-specific training Emergency response training, first aid, and basic safety. Required to maintain records of training for past two years, and receive new training every 3 years. Precautions Don't carry pesticide in passenger compartments Ensure that containers of pesticides are secure Ventilate cargo compartments (vans), inspect vehicle to make sure there is no hazard in the compartment Have emergency kit on hand (for cleanup and first aid) Have documents on hand (MSDS, DOT papers) Storage Improper storage can be hazardous to health and environment. Stockpiles of pesticides that may accidentally leak or spill will waste money. Proper storage will extend the shelf life of the chemical. Storage - Precautions Store pesticides in locked cabinets. Store at least 5 feet above ground away from children and pets and away from areas that are likely to flood. Always store pesticides in their original containers with their tops tightly closed. Never store pesticides in any food or drink containers. Store pesticides in a cool, dry place to prevent deterioration. Store pesticides away from food, potable water, medical supplies, protective clothing, seed, or fertilizers. Store dry pesticides above liquid pesticides to avoid contamination Storage - Precautions cont. Never store pesticides in application equipment. This will prevent accidents related to handling and storage of equipment Buy only the amount and type of pesticide needed for the upcoming year. Pesticides will become ineffective as they become older. Avoid having excess mixture in equipment. Keep the vehicle maintained Inspect the vehicle to make sure there are no pesticide residues Waste of money and increase risk if you do not need the pesticide. Storage containers must be in compliance with EPA standards, and DOT standards if the pesticide is to be transported. Packaging Like transportation, packaging falls under the authority of the FDA and DOT. If the pesticide is to be exported, it must meet standards of the United Nations, not only domestic standards. Materials are placed into packing groups, which are based on the degree of danger caused by hazardous material. Packing Groups Packing groups can be based on the danger of the class the material is in. Packing groups are rated 1-3, 1 being the most dangerous and 3 having only minor danger. If a material has a package group, it will be packaged in materials that are best chemically compatible. Packing Groups - Pesticides Pesticides in a poison class can be in packing groups 1-3, and are in packing groups 1 and 2 for flammability If a pesticide is poisonous and flammable, the flammability is counted as a secondary danger. Packing Groups - Pesticides Packing Group Flammability Toxicity 1 2 3 < 5mg/kg <5mgkg and
<50mg/kg <50mg/kg and
<500mg/kg Flash point Boiling Point < 23°C >23°C and
<60.5°C < 35°C >35°C >35°C Danger is determined by flash point, boiling point, and toxicity in mg/kg. A higher flash point, boiling point, and toxicity level is safer. Packaging Packages must have the proper labeling which must include ID #, class, group, and shipping name There are different ID #'s for domestic and UN. Packaging standards are based on the performance of a package. Drop resistance, leak resistance, hydrostatic pressure, vibration resistance, ability to stack. ID # indicates what capabilities and properties the packaging possesses. Conclusion The EPA and DOT both enforce transportation and packaging of pesticides if they are hazarous materials. Staff which handle these materials must receive proper training and are required to take safety measures to ensure public and environmental health Pesticides are in only two classes of hazardous materials but can be in all three packing groups. Safe storage of pesticides consist of various safety measures. The location and conditions around the pesticides is extremely important to keep risk of accident low. Questions
? Placards can also be color coded as well (such as red for flammable materials). Sources http://oeh.cals.cornell.edu/pdf/DOTPesticides.pdfhttp://www.unce.unr.edu/publications/files/ag/2001/sp0109.pdf
