Labeling dangers

Flammable solids and organic peroxides having, as tested, explosive properties and which are packed in such a way that the classification procedure would require the use of an explosives label as a subsidiary risk label. Dangerous goods listed in Table 15.9... 

Attempts to label dangerous substances with either characteristic or outright unpleasant odors have not been successful with children, the primary victims of accidental poisonings by toxic household products. Children tolerate odors that adults find unpleasant, such as that of butyric acid. The range between the most pleasant and unpleasant odors is much narrower for children around 4years of age than for adults, and also much narrower than for taste stimuli. This means that olfactory cues are not suited to produce aversive responses in children (Engen, 1974b, Cain, 1978).

DOT CLASSIFICATION 9 Label CLASS 9 (NA 9260) DOT Class 4.1 Label Flammable SoUd (UN 1309) DOT Class 4.3 Label Dangerous When Wet (UN 1396) SAFETY PROFILE Although aluminum is not generally regarded as an industrial poison, inhalation of finely divided powder has been reported to cause pulmonary fibrosis. It is a reactive metal and the... 

ACGIH TLV TWA 2 mg(Al)/m3 DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE Hydrides of some metals (such as ASH3) are extremely toxic. Dangerous fire hazard. An unstable material which is spontaneously flammable in air or O2. Evolves explosive H2 upon contact with moisture. Severe explosion hazard by chemical reacdon wherein H2 gas is produced, also in contact with methyl ethers contaminated by CO2. Mixtures with tetrazole derivadves are explosive. Reacts with oxidizing materials. On contact with acid or acid fumes, it can emit toxic fumes. See also HYDRIDES and ALUMINUM COMPOUNDS. 

ACGIH TLV TWA 2 mg(Al)/m3 DOT CLASSIFICATION 4.3 Label Dangerous When Wet, Poison SAFETY PROFILE A poison. Dangerous fire hazard. Evolves spontaneously flammable PH3 in contact with water. See also PHOSPHIDES, PHOSPHINE,...

DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE Reaction on contact with moisture forms explosive acetylene gas. Flammable on contact with moisture, acid or acid fumes evolves heat or flammable vapors. Moderate explosion hazard. Incandescent reaction with CI2 (245°C), Br2 (350°C), I2 (305°C), HCl gas + heat, PbF2, Mg + heat. Incompatible with Se, (KOH + CI2), AgN03, Na202, SnCb, S, water. Mixtures with iron(III) chloride, iron(III) oxide, tin(II) chloride are easily ignited and burn fiercely. Vigorous reaction with methanol after an induction period. 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE Poison by ingestion, inhalation, skin contact, intravenous, and intraperitoneal routes. Moderately toxic to humans by ingestion. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. The fatal dose, by ingestion, is probably around 20 to 30 g for an adult. It does not have a cyanide effect. Calcium cyanamide is not believed to have a cumulative action. Flammable. Reaction with water forms the explosive acetylene gas. When heated to decomposition it emits toxic fumes of NOx and CN". See also CALCIUM COMPOUNDS, AMIDES, and CYANIDE. 

DOT CLASSIFICATION 4.3 Label Danger When Wet, Corrosive, Flammable Liquid SAFETY PROFILE Poison by ingestion and inhalation. A severe irritant to skin, eyes, and mucous membranes. Corrosive. Dangerous fire hazard if exposed to heat, open flames, or powerful oxidizers. Will react with water or steam to produce heat and toxic and corrosive fumes. To fight fire, use foam, dry chemical, mist, spray. When heated to decomposition it emits toxic fumes of CL and phosgene. See also CHLOROSILANES. 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE Moderate inhalation hazard. Low skin toxicity. Reaction with moisture releases hydrogen and acetylene gases, which then ignite impurities in the alloy may liberate such poisonous and reactive gases as phosphine and arsine. Dty mixtures with sodium hydroxide react incandescently when water is added. Reaction with acid, acid fumes, or oxidizing materials can emit toxic fumes. Reaction... 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet (UN 2950) DOT Class 4.1 Label Flammable Solid (UN 1869) DOT Class 4.3 Label Danger When Wet, Spontaneously Combustible SAFETY PROFILE Inhalation of dust and fumes can cause metal fume fever. The powdered metal ignites readily on the skin causing burns. Particles embedded in the skin can produce gaseous blebs that heal slowly. 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet, Flammable Liquid SAFETY PROFILE May ignite spontaneously in air. A very dangerous fire hazard when exposed to heat or flame can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHERS, MAGNESIUM COMPOUNDS, and BROMIDES. 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE The toxicity of potassium compounds is almost always that of the anion, not of potassium. A dangerous fire hazard. Metallic potassium reacts with moisture to form potassium hydroxide and hydrogen. The reaction evolves much heat, causing the potassium to melt and spatter. The reaction also ignites the hydrogen, which burns, or if there is any confinement. 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE A low-melting alloy of Na and K. Its toxicity is due to either Na or K alone. Corrosive to the eyes, skin, and mucous membranes. Upon contact with moisture it reacts violently to evolve H2 much heat and a highly caustic residue of NaOH or KOH. Oxidation forms Na20 and K2O, which are powerful caustics. 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet SAFETY PROFILE Moderately toxic by intraperitoneal route. A ver reactive alkaK metal (more reactive than potassium or cesium). In the body, rubidium substitutes for potassium as an intracellular ion. The ratio of Rb/K intake is important in the toxicology of rubidium. A ratio above 40% is dangerous. In rats, a failure to gain weight is the first symptom, followed by ataxia and hyperirritabihty. Symptoms include skin ulcers, poor hair coat, sensitivity, and extreme nervousness leading to convulsions and death. 

Amid-Thin (naphthalene acetamide) is labeled Danger because of the potential of severe irreversible eye damage, whereas Fruitone N, NAA 800, and Tree-Hold Sprout Inhibitor (NAA) are relatively nontoxic (Category III). See Table 5.28 for a listing of commercial products.
