No data on industrial experi ence m the United States has been published Bisphenol A has been considered a nuisance dust Unaccluiidted personnel can withstand concentrations approaching 15 mg/m3 before complaining of ocular or nasal irritation An adequate ventilation system should be em ployed to maintain airborne dust below the TLV If circumstances arise which do not permit adequate control at the source, then approved respiratory protective devices should be used to prevent inhalation of bisphenol A dust Clothing must be frequently laundered to prevent continuous slan contact, personal cleanliness is essential to avoid skin difficulties Boric acid has been used for many years as a mdd disinfectant and a soothing and slightly astringent wet dressing or ointment with little attention to its toxicity Poisoning is not usually an industrial prob lem since the human system processes and eliminates fairly large quantities of bone acid without trouble, but it may result from mis guided first aid attempts Bone acid is not readily absorbed through the intact skin, but may be absorbed through large areas of skin which are senously dam aged, as in bums or areas of superficial lacera tions If such areas are dusted with bone acid or covered with strong bone acid oint ment, toxic amounts may be absorbed Boron hydrides are a senes of compounds analogous to the hydrocarbons, and include diborane, pentaborane, and decaborane, which have found use as high-energy fuels Diborane is pnmanly a lung-injuring matenal and produces lung changes in rats m one to four weeks of daily exposure at about 2 ppm The compound has an odor, but it is not detectable at a low enough concentration to act as a warning of the possibility of chronic poisoning Pentaborane, unlike diborane, principally affects the central nervous system In labora tory animals it produces first a temporary ex citement and hypersensitivity which may lead 1130 to convulsions, and then a profound depres sion Decarborane is similar m its action on the system to pentaborane It can be cumu latively absorbed over a short senes of ex posures and the total dose, although less than a single lethal dose, may stiff cause death In practice it is probably more dangerous to handle than pentaborane, since, in addition to being toxic by inhalation, decaborane is rap idly absorbed through the intact skin At tempts to treat or counteract its toxicity have been unsuccessful Boron hydndes should be handled only in a closed system in a well-hooded and venti lated area Self-contained or supplied air respiratory protection should be provided if the system must be opened (filter-type respi rators are not effective) For the handling of decaborane, impervious clothing should also be used to prevent skin contact Brass, chiefly an alloy of copper and zinc, may also contain lead Melting of brass may produce copious quantities of zinc oxide fume which, if inhaled, may give nse to the signs and symptoms of metal fume fever (Refer to listings for Copper, Lead, and Zinc in this chapter ) Bromine is a dark red, low-boding liquid which produces large quantities of extremely irritant, nonflammable vapor at room tempera ture or above Its physiological effects are about the same as those of chlorine--irritation of all mucous membranes and the lungs and spasm of the glottis when inhaled in fairly large concentration A bromine concentration of 40 to 60 ppm is reported to be dangerous on short exposure The irritant action of bromine is not related to the bromide intoxication seen from time to time from continued overdoses of bromides as sedatives In bromide intoxication, the most notable effects are on the central nervous system and are seen as slurring of speech, somnolence, difficulty in walking, and various psychic disturbances, depending on the per sonality of the individual involved Bromochloromethane (methylene chlorobromide) Knowledge of effects m humans is limited at present Anesthesia is the primary

There seems to be no correlation between anemia, stippling and the amount of lead present in the blood.

I have always used the same organisation to investigate lead levels in children and I am glad to say that the investigations that I have been able to do with some money provided by the company, proved quite frank cases of lead poisoning in children was not due to atmospheric contamination but was due in every case to paint, water and particularly, as has come out recently, from improperly glazed earthenware jugs.

Lead casts Lead casts are taken m practically every conceivable manner m the forging industry.

breathing apparatus This can be either a compressed-air type of self-contained breath ing apparatus, or self-generating or air sup plied type The fit of the facepiece should be carefully checked before the workman enters the tank If the environment contains a sub stance that is dangerously irritant or corrosive to the skin (lead tetraethyl, for example), the breathing apparatus may be supplemented by complete attire of impervious clothing Some medical authorities advise that in dividuals with broken eardrums not work m vapor-laden atmospheres, because no mask will protect these abnormal openings The supplied fresh-air hose mask with blower is generally the best type of respira tory equipment for continuous use inside a tank Proper procedures A tank should be gas freed before any work is performed inside it A worker should not be allowed to enter a gassy or oxygen-deficient tank unless abso lutely necessary, such as m an emergency When this is necessary, the man should be attended on the outside by another worker who is similarly outfitted with appropriate respiratory protection and protective attire as needed so that the latter can rescue the man in the tank if necessary In some states this is a legal requirement Men engaged in tank cleaning should be instructed in the method of giving artificial respiration, and should be retrained peri odically If a tank cleaner is overcome by vapor or gas, he should be removed to fresh air immediately and given artificial respira tion until he resumes breathing A physician should be summoned, and the resuscitated man kept quiet and warm until breathing and circulation are normal The sense of smell cannot be relied upon for an accurate estimate of the amount of flammable vapor present in a tank It does, however, give warning that vapors of some kind are present Symptoms of dizziness, nausea, and headache indicate that a danger ous concentration of flammable and toxic vapors is present Exposed workers should leave the contaminated area immediately and not return until vapors have been cleared Workers should always have a clear path of escape from a tank and should bear m mind that they may have to use it in a hurry A ladder should always be used when a tank must be entered from above, and it should be left secured in place until the last man is out of the tank Under severe conditions, a life line is recommended to assist with rescue work Burning, welding, cutting, and spark-producing operations should not be permitted in a tank until the area to be heated has been thoroughly cleaned and tests have determined that the tank atmosphere is vapor free Where any vapor is present, further ventilation will be required to remove the vapor from the tank Hot work repairs (welding and cutting) should not be made whenever other means can be used more safely Even after a tank has been freed of vapor, combustible mixtures again may be formed through admission of flammable vapors or liquids from other sources, such as an unblanked line or connec tion, a break m the bottom of the tank, sludge, sediment, or sidewall scale, or wood struc tures soaked with the liquid The interior framing of floating tank roofs can trap quan tities of liquids that will release vapors Therefore, periodic tests with a combustible gas indicator should be made during the hot work Burning or cutting may release lead fumes from paint on either the inner or outer sur face of the tank or from some other source An approved mask for protection against lead may be necessary, or it may be advisable to exhaust the fumes Wood supports inside the tank should be protected or removed before hot work is begun Some companies use low-voltage trans formers to eliminate the danger of electric shock, especially when men are required to work in wet areas All portable electrical equipment should be grounded Cold work in a tank may present a dust problem, and approved dust respirators and goggles should be worn if tests definitely show that wearing of a hose mask is not necessary Gas tests should be made frequently if the presence of gas is suspected The concen tration of gas or vapor m a tank or vessel may increase as work progresses, especially if the inside of the tank is scraped or heated dunng the operation 1037
