The cooled piranha solution may be transferred into the piranha waste bottle. Experience. 3. in waste solvent carboys), as this will cause a violent reaction and a substantial explosion. PIRANHA’CLEANING’–’GLASS’SURFACES’ ©Moran(MirabalResearchGroup" 3/3" keep)the)temperature)in)the)appropriate)range. It should not be stored in a closed container. Slowly dilute 1 in 10 with water using clean glassware and a stirrer (i.e. This allows the spent solution to degrade prior to disposal. Critical functions related to hazardous waste, public health, and research safety are operational. Do not neutralize it by adding a base, as the rapid decomposition releases heat and pure oxygen gas. Piranha solution reacts violently with any organic materials. Quantities less than 100ml should be neutralized. The Pirana is the first new technology and method for onsite septic systems that finally allows us to recycle human sewage onsite, not just the contaminated water, since cesspools and septic systems began being used over 130 years ago. REUPLOADED DUE TO SOUND ISSUE.In this video we make and demonstrate the oxidizing power of piranha solution. Piranha solution is highly energetic and has many potential hazards. This includes acetone, photoresist, isopropyl alcohol, and nylon. REUPLOADED DUE TO SOUND ISSUE.In this video we make and demonstrate the oxidizing power of piranha solution. Chemical safety has many scientific and technical components.

Septic solutions are quick and cost-effective with PIRANA Systems. Relevant identified uses of the substance or mixture and uses advised against Intended use See Technical Data Sheet. It is highly corrosive and an extremely powerful oxidiser. ... 3.0 Waste Disposal: 3.1 Piranha waste: 3.1.1 Solid waste should go in the acid waste bin. If you store a hot piranha solution in an airtight container, it will explode! A less hazardous solution/process should be used if possible. While some institutions believe that used Piranha solution should be collected as hazardous waste, others believe that it can be poured down the drain with copious amounts of water. As such, this method is generally considered a last resort in disposal, and it's mostly used for Piranha solution is likely to become hot, more than 100 degrees Celsius. Trained employees and equipment are available 24 hours/day, 7 days/week to respond to such emergencies. Safety Alert: Piranha and Gas Producing Mixtures. Certain chemicals can be harmful to our health and environment, it is therefore important to ensure the safe management of chemical materials for use, disposal, storage, acquisition, inventory control, and regulatory compliance. Only pre-approvedacid piranha solutions containing Sulfuric acid and Hydrogen Peroxide will be accepted for proper disposal. NFPA National Fire Protection Association; Fire Protection Guide to Hazardous Materials. Piranha solution is likely to become hot, more than 100 degrees Celsius. Piranha solution should be allowed to cool, and oxygen gas should be allowed to dissipate prior to disposal. 3.1.2 Liquid waste should go in the “Piranha” (that is, Sulfuric Acid and Hydrogen Peroxide) glass waste bottle in the hazardous waste accumulation area. Put five times as much ice as the amount of the solution you want to neutralize into a container large enough to hold the ice, the piranha and the neutralizing solution (e.g., use 500 g of ice for 100 ml piranha solution). Riverside, CA 92521, Environmental Health & Safety 1940), “Young people everywhere have been allowed to choose between love and a garbage disposal unit. Septic solutions are quick and cost-effective with PIRANA Systems. Incidents involving the use and disposal of acidic ‘piranha’ solutions indicate a heightened potential for serious injury to campus researchers, EH&S staff and staff of the hazardous waste disposal vendor handling piranha wastes for final disposal. (EH&S provided), Cap poly-coated bottle with a vented cap. Handle with care. The primary hazard from storage of piranha etch waste is the potential for gas generation and over pressurization of the container when the solution is still hot. SOP: Strong Oxidizers. If you store a hot solution in a air tight container, it will explode! A less hazardous solution/process should be used if possible. Relevant identified uses of the substance or mixture and uses advised against Intended use See Technical Data Sheet. Piranha solution is very dangerous, being both strongly acidic and a strong oxidizer. hydrogen peroxide, bringing the total volume of solution up to 1000 mL). Piranha solution can be heated to high temperatures due to the enthalpy of solution: Handle with care. You may request vented caps from the Chemical Waste Pickup / Services Online Request. Chemical piranha solution or piranha etch is a mixture of a strong acid or base with peroxide, mainly used to remove organic residue from glass and other surfaces. If you store a hot solution in a air tight container, it will explode! Heat insulated gloves may benecessary. 4 - Piranha waste disposal 1. This means the solution can easily dissolve fabric and skin causing severe chemical burns in the process. Recent incidents involving the disposal of acidic 'piranha' solution (sulfuric acid, H2SO4 and hydrogen peroxide, H2O2) indicates a heightened potential for serious injury to campus researchers, EH&S staff and staff of hazardous waste disposal vendors for UCR that handle piranha waste for final disposal.
