13、ute FOREWORD This publication emphasizes that the use of nonferrous hand tools,sometimes referred toas nonsparking tools,is not warranted as a re prevention measure in petroleum operations.This position,based on experimental studies relevant to work associated with hydrocarbonsin the petroleum indus
14、try,is supported by real world experience over many decades.Thispublication does not address work around materials with lower ignition energies-such asexplosives,accelerants or oxygen enriched atmospheres-for which different data sets couldapply.Some studies emphasize that the term low sparking is m
15、ore appropriate than non-sparking for these nonferrous tools.API publications may be used by anyone desiring to do so.Every effort has been made bythe Institute to assure the accuracy and reliability of the data contained in them;however,theInstitute makes no representation,warranty,or guarantee in
