This Directive establishes rules for the safe transport of dangerous goods between EU countries by road, rail, and waterway. If large amounts of this compound are inhaled, move the person to fresh air and seek medical attention at once.Low acute toxicity; skin and eye irritant.Diethyl ether is extremely flammable (NFPA rating = 4) and is one of the most dangerous fire hazards commonly encountered in the laboratory, owing to its volatility and extremely low ignition temperature. Acetaldehyde is mutagenic and has been shown to be a reproductive toxin in animals. Small spills may be collected and carefully hydrolyzed with a large excess of cold water, neutralized with base, and disposed of properly. If acetone is ingested, obtain medical attention immediately. ""Paint-thinner-like" odor detectable at 12 ppmAnhydrous HF: 775 mmHg at 20 °CIodine should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C. Reaction with water generates highly corrosive lithium alkoxides and lithium hydroxide.Highly toxic; exposure by eye or skin contact or ingestion can be rapidly fatal.Slightly soluble in water (0.7 g/100 mL)(Acrylaldehyde, acrylic aldehyde, 2-propenal)Highly soluble in water (89.9g/100 mL at 0 °C)White phosphorus reacts with a number of substances to form explosive mixtures. Concentrations of acetylene above 50% in air can cause death by asphyxiation within 5 min.
Diborane has not been shown to have carcinogenic or reproductive or developmental effects in humans.Repeated or prolonged contact may cause dermatitis. Inhalation of hydrogen chloride gas can cause severe irritation and injury to the upper respiratory tract and lungs, and exposure to high concentrations may cause death. Containers of hydrochloric acid should be stored in secondary plastic trays to avoid corrosion of metal storage shelves due to drips or spills.Chronic toxin affecting the kidneys and central and peripheral nervous systems; reproductive and developmental toxin.In the event of a spill of dilute hydrofluoric acid, soak up the acid with an HF-compatible spill pillow or neutralize with lime, transfer material to a polyethylene container, and dispose of properly. In an experimental investigation, four human subjects tolerated 0.57 ppm iodine vapor for 5 min without eye irritation, but all experienced eye irritation in 2 min at 1.63 ppm. Exposure to formaldehyde gas can cause irritation of the eyes and respiratory tract, coughing, dry throat, tightening of the chest, headache, a sensation of pressure in the head, and palpitations of the heart.
Alternatively, acetaldehyde spills may be neutralized with sodium bisulfite solution before cleanup. An oral dose of 30 to 100 mL of 37% formalin can be fatal in humans. With a very high positive free energy of formation, acetyleneReactivity and incompatibility,Slightly soluble in water (0.4 g/100 mL at 20 °C)In cases of eye contact, immediate and continuous irrigation with flowing water for at least 15 min is imperative. Chronic exposure to HMPA can cause damage to the lungs and kidneys. the electronic edition of the Official Journal of the European Union.It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. Ether vapor forms explosive mixtures with air at concentrations of 1.9 to 36% (by volume).
in case of consumer and professional uses). Poisoning can occur by inhalation of mists of cyanide solutions and by inhalation of HCN produced by the reaction of metal cyanides with acids and with water.
Explosions have been reported to occur, for example, on addition of bromine to methanol, acetaldehyde, and DMF.
Cyanide salts should be stored in a cool, dry location, separated from acids.In the event of a spill, remove all ignition sources and close off the hood. Powdered LAH forms dusts that can pose an inhalation hazard. In case of eye contact, promptly wash with copious amounts of water for 15 min (lifting upper and lower lids occasionally) and obtain medical attention.
In the event solutions containing chromium compounds are spilled, neutralize (if possible) with aqueous base, soak up with a spill pillow or appropriate noncombustible absorbent material, place in an appropriate container, and dispose of properly. There is some evidence that chronic exposure to palladium particles in dust can have toxic effects on the blood and respiratory systems. This substance is readily absorbed through the skin and may cause systemic toxicity as a result. In case of eye contact, promptly wash with copious amounts of water for 15 min (lifting upper and lower lids occasionally) and obtain medical attention.
Formalin solutions can cause severe eye burns and loss of vision. ), hydrazine decomposes to ammonia, hydrogen, and nitrogen gases, which may ignite or explode.Acetic acid should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C. Carbon disulfide is a strong skin irritant; dermal exposure may result in severe burns.
