Since being granted permission for self-assessment of the work environment by the Department of Labor in 1992, POSCO´s Industrial Hygiene Laboratory has participated in domestic and Foreign Quality Control Programs 8 times and has obtained remarkable results.
It has made a lot of effort to be a proficient laboratory with the ability to observe and analyse environmental monitoring data.
The summary of results is as follows:
1. POSCO´s Industrial Hygiene Laboratory has received a $quot;P(Proficient)$quot; grade from the round 115 to round 119 of AIHA/NIOSH PAT Program for analysis of such metals as lead, cadmium, zinc, and chromium, and also has received a $quot;P(Proficient)$quot; grade from its round 119 of for organic solvent analysis, i,e,. Trichloroethyiene(TCE), Carbon Tetr-achloride(CTC), 1.2-Dichloroethane(DCE), 1,1,1-Trichloroethane(MCM), Tetrachloroethylene (PCE), Chloroform(CFM), Benzene(BNZ), toluene(TOL), and O-xylene(OXY).
2. In the Quality Control Evaluation Program performed by the Industrial Health Research Institute, Korea Industrial Safety Corporation, POSCO has passed impressively in the 3-metal analysis test for lead, cadmium, cupper, and in the 6 organic solvent analysis test for Benzene(BNZ), toluene(TOL), O-xylene(OXY), Trichloroethylene(TCE) and Methyl isobutyl keton(MIBK), n-Hexane with 2 standard deviations.
These analytic techniques should be practically applied to various fields, and reliable results of environmental monitoring should be considered to improve the work environment and to keep workers from occupation related diseases.
