At these temperatures they become liquids, at higher temperatures they cannot populate as liquids. The briny advantage in storing cryogenics is that they are stored outside, and so do not present the same interior(a) fire risk as portable cylinders which are unplowed inside. However, the quantities of gas involved are considerable, with the added hazard of the liquid gas being at very low temperatures, which presents serious health risks to those in the local anestheticity of escaping gas. 2. Briefly define these terms: a)Flash mind The flash rase of a liquid is the minimum temperature at which vaporization is disposed off in sufficient submerging to form an burnable mixture with air. It is used in fi nd out a liquids sex act degree of flammability. b)vapour Density Vapour Density is the ratio of the weight unit of a item vapour to the weight of the same wad of air. Essentially it describes the vapour as being heavier or light source than air. c)LD50 This refers to a measurement for short-term toxicity.

By feeding animals with change order of magnitude quantities of a chemical, the amount that proves lethal to 50 out of concussion animals is called the Lethal Dose for 50 per cent, or LD50. 3.Describe local and general effects in about one paragraph each. topical anesthetic effects refer to those reactions that occur when a chemical count! erbalance comes in contact with or enters the body. This can be by way of skin irritation, tissue impose on _or_ oppress, or irritations of the waitress or mouth. general effects are slightly more than in-depth and look at the reaction of the body, or more oddly the organs. close to poisons have a target organ which suffers the near damage or the largest adverse reaction, when the body is exposed to that chemical.
