(2) What causes the scale in the tanks? (3) What is the cause of lead decomposition? (4) What effect does gum in gasoline have on lead if any ? (5) Are the tanks treated in any way to pervent corrosion? (6) Does lead have an affinity for water? (7) HKSXH Is air kept away from stored fuel, or, are the tanks allowed to breathe ? (8) Are some men more suscept&ble to lead poising than others? )9) la fresh air circulated in the tanka during the cleaning process? (10) If a person perspires will more^or less, lead be absorbed? (11) How does lead poisoning effect the human body? (12) Is there a remedy for lead poison? (13) Is there any electrolytic action 33Y3UKli taking place while the leaded fuel is in storage?
