Safe handling of special chemical hazards
Toxic. Avoid contact with skin and eyes. Use effective fume removal device.
Toxic. Highly flammable. Avoid contact with skin. Do not breathe vapours. Use effective fume removal device. Decomposes violently in presence of strong oxidizing agents. Reacts violently with Cl . Considered to be carcinogenic.
Highly flammable. Forms explosive peroxides with oxidizing agents. Use effective fume removal device.
Bromine and chlorine
Hazardous with NH , H , petroleum gases, turpentine, benzene and metal powders. Extremely corrosive. Use effective fume removal device. Protect skin against exposure.
Reacts violently with alkali metals. Toxic. Fumes may decompose to phosgene when heated strongly. Use effective fume removal device.
Can be harmful if inhaled. Forms phosgene when heated to decomposition. Use effective fume removal device. Can react explosively with Al, Li, Mg, Na, K, N O and NaOH plus methanol.
Highly flammable. Use effective fume removal device. Can react vigorously with strong oxidizing agents.
Store protected from light. Extremely flammable. Unstable peroxides can form upon long standing or exposure to sunlight in bottles. Can react explosively when in contact with Cl , O , Li, Al, H or strong oxidizing agents. Use effective fume removal device. Avoid static electricity.
Flammable. Use effective fume removal device when heating or evaporating.
Hazardous with oxidizing gases, fuming HNO and Na O . Forms explosive mixtures with air.
Toxic. Use effective fume removal device.
Highly flammable. Use effective fume removal device.
Flammable. Toxic. Avoid contact with eyes. Avoid breathing vapours. Use effective fume removal device. Can react vigorously with NaOH plus CHCI , and KOH plus CHCl or HCIO .
(Perchlorates, peroxides, permanganates, persulfates, perborates, nitrates, chlorates, chlorites, bromates, iodates, concentrated H SO , Concentrated HNO , CrO .) Can react violently with most metal powders, NH , and ammonium salts, P, many finely divided organic compounds, flammable liquids, acids and S. Use exactly as specified in method. Handle in effective fume removal device from behind explosion-resistant barrier. Use face shield.
Hydrogen Peroxide: 30% strength is hazardous; can cause severe burns. Drying H O on organic material such as paper or cloth can lead to spontaneous combustion. Cu, Fe, Cr, other metals and their salts cause rapid catalytic decomposition of H O . Hazardous with flammable liquids, aniline and nitrobenzene. Since it slowly decompose with evolution of O , provide stored H O with vent caps. Wear gloves and eye protection when handling. Either peroxides -These peroxides form in diethyl ether, dioxane and other ethers during storage. They are explosive and must be destroyed chemically before distillation or evaporation. Exposure to light influences peroxide formation in ethers. Filtration through activated alumina is reported to be effective in removing peroxides. Store over sodium ribbon to retard peroxide formation.
Extremely flammable. Use effective fume removal device. Avoid static electricity.
Silver nitrate (AgNO )
Powerful oxidizing agent; strongly corrosive. Dust or solid form is hazardous to eyes. Handle as noted for oxidizers.
Moderately toxic. Readily soluble in water. Strong oxidizing agent. May form explosive mixture with H SO or HClO . When using with strong acids to destroy organic matter, perform reaction behind safety barrier.
Mycotoxins should be handled as very toxic substances. Perform manipulations under hood whenever possible. All mycotoxins are potential health hazard in one way or the other, Aflatoxin B is a highly carcinogenic substance and shall therefore be handled very carefully. Do not transfer dry aflatoxin for weighing or other purposes unless facilities (e.g., glove box) are available to prevent dissemination of aflatoxin to surroundings due to electrostatic charge on particles. Rinse all glassware exposed to aflatoxin carefully with chloroform, then with solution of NaOCl bleach (5% v/v solution in water) and then wash thoroughly. Swab accidental spills of aflatoxins with the solution of NaOCl bleach.
