Treatment of mine timbers
Timber properly treated with creosote will last three to five times as long as untreated timber, depending on species; treatment with zinc chloride and sodium fluoride will increase service life two or three times, if salts are not used where wash of water will reach salts from treated timber; mine staff seldom includes man with experience or time to study local conditions; advantages of commercial treatment plants; comparative fire risks with creosote and with soluble salts.
