Boiling eruptions

A boiling liquid eruption in a hydrocarbon or chemical storage tank. Usually described as an event in the burning of the contents of the tank, where after a long period of time, there is a sudden increase in fire intensity with the expulsion of the contents of the tank, due to water at the bottom of the tank being heated to vaporization and causing a boiling eruption. 

Reaction with methanol may be vigorously exothermic. A mixture of bromine (9 ml) and methanol (15 ml) boiled in 2 m and in a previous incident such a mixture had erupted from a measuring cylinder [1], The exotherm with industrial methylated spirits (ethanol containing 5% methanol) is much greater, and addition of 10 ml of bromine to 40 ml of IMS rapidly causes violent boiling [2], A further case of ejection of a methanol solution of bromine from a measuring cylinder was described [3],... 

When a reaction mixture is heated, there is a tendency for it to boil violently as large bubbles of superheated vapour suddenly erupt from the mixture. This is prevented by the addition of the anti-bumping granules. A condenser is placed in the mouth of the flask and connected to a cold-water tap (water goes in at the bottom and out at the top). The flask is then heated and the vapours produced are condensed back into liquids when they reach the cool condenser. 

Acid containers must be kept closed. Water must not enter containers. When diluting the acid, always add the acid slowly with agitation to the surface of the aqueous solution to avoid violent spattering, boiling, and eruption. Never add the solution to the concentrated acid. 

Geyser A spring that periodically erupts hot water and steam because of the boiling of groundwater from shallow magmas (compare with hydrothermal and geothermal waters). 

Reaction with methanol may be vigorously exothermic. A mixture of bromine (9 ml) and methanol (15 ml) boiled in 2 m and in a previous incident such a mixture had erupted from a measuring cylinder [1], The exotherm with industrial methylated... 

Pulsatilla possesses sedative, analgesic, antispasmodic, and bactericidal properties. Traditionally, it is used for dysmenorrhea, orchitis, ovaralgia, epididymitis, tension headache, hyperactive states, insomnia, boils, skin eruptions associated with bacterial infection, asthma and pulmonary disease, earache, and specifically for painful conditions of the male and female reproductive systems. Pulsatilla is widely used in homoeopathic preparations as well as in herbal medicine. 

The liquid from 1 ounce of the root boiled in 1A pints of water simmered down to 1 pint, is taken four times daily in wineglass doses for many forms of skin trouble, noticeably boils, carbuncles and similar eruptions. Obstinate cases of eczema and even psoriasis have been known to yield to these decoctions of Burdock root, either alone or combined with other remedies. 

Inflammation of the respiratory organs and internal membranes generally. One ounce of herb in 1 1/2 pints of water simmered down to 1 pint. Dose, wineglassful every two or three hours. Used externally as a poultice for inflamed surfaces, boils, burns and skin eruptions. 

The action of Comfrey is similar to that of Marsh Mallow, and consequently it is a popular cough remedy. It is also used as a fomentation in strained and inflammatory conditions of the muscles, and will promote suppuration of boils and other skin eruptions. A decoction is made by boiling 1/2 to 1 ounce of the crushed root in 1 quart of water,... 

The infusion of 1 ounce of the flowers or herb to 1 pint boiling water is prescribed both for internal use in 1-2 tablespoonful doses, and externally as a lotion for chronic ulcers and varicose veins. The infusion is also given to children (in doses according to age) suffering from measles and other feverish and eruptive complaints. Sprained muscles gain relief from the hot fomentation. Marigold is frequently combined with Witch Hazel when a lotion is required. 

Slippery Elm bark coarsely powdered makes one of the best possible poultices for boils, carbuncles, chilblains, and skin eruptions generally. It soothes the part, disperses inflammation, draws out impurities, and heals rapidly. 

A potentially explosive situation can develop when an acetone slush bath is left sitting for an extended period. Over time, the acetone and dry ice separate and the acetone floats to the surface, whereas the dry ice settles to the bottom of the Dewar. The acetone soon warms up to near room temperature, but the dry ice remains near the slush bath temperature of -77°C. If any agitation causes the warmed acetone to cut into the dry ice slush on the bottom, a flume of boiled off C02 can erupt. This flume will carry the acetone layer that was on the surface in a large spray all around the area.11 If there is a flame or spark (from a motor) in the path of the acetone, this accident could have far greater consequences. This situation can be easily avoided by constantly mixing the solution. A safe alternative to the acetone slush bath is the ethanol slush bath. The ethanol slush bath is somewhat warmer (-72°C) but does not display the same potentially dangerous capabilities. 

Molecular weight 1 8.24. It has a specific gravity of 1.250, melts at 216.2°C, boils at 3 2 C. Insoluble in water, and hardly soluble in alcohol(0.076 g per 100 g of ethanol at room temperature). Purified anthracene has pure white snow-like crystals, but is generally somewhat yellowish. In summer it sometimes causes trouble with workers by producing skin eruption but this varies with constitution. It is used for compositions of black smoke. 

Drain cleaners are generally one of two types, sodium hydroxide or sulfuric acid. Numerous accidents have occurred when users have first applied one and, when it did not clear the drain, subsequently the other. The neutralization reaction of sodium hydroxide and sulfuric acid generates a large quantity of heat, sufficiently large enough to rapidly heat water present to its boiling point and result in a violent eruption. Numerous individuals have suffered eye and skin burns because of unreacted sodium hydroxide or sulfuric acid that has thus erupted.
