Abstract

|
|
As a result of having examined reliability of MSDS record contents about powder coatings, MSDS and warning labels
reliability of were very low levels. The composition chemical substance used for production of powder coatings to
synthetic resin, hardening agent, pigment, an additive. The Lead chromate was contained in 0.1-25% by suspected
human carcinogen substance by 9 powder coatings, and silica was contained in 5-20% by cause substance of
silicosis by 3 powder coatings. The inhalable particulate mass(0-10㎛) was approximately 2.75% in particle size of
powder coatings, and the thoracic particulate mass(0-25㎛) was approximately 22.3%. If chemical substance composition component was omission of record and only a part list was 34.1% in MSDS, and it was a state to be low with 59% if a harmfulness classification was omission of record and a part list for it. A composition component and a content did not become a record in warning labels of all powder coatings, and a hazard pictographs of warning labels was approximately 56.8% if not adhesion. If toxicity information about powder coatings was omission of record, it was 97.7%, and the case that omission of record an TLV-TWA about component chemical substance was 75% level. There are an increasing number of problems associated with the regular monitoring of workplace environment, based on MSDS; more and more health-related problems are related to the management of harmful chemical substances. Under these circumstances, regarding these harmful substances, there is a compelling need for systematically examining the accuracy of MSDSs, and deeply investigating and evaluating toxic chemicals.
