An Experimental Research of the Release Characteristics of the Transformer Oil in Workplace

Transformer oil emitted at the workplace can impose great risks to the workers. 1, 1-Diphenylethane and 4-Methyldiphenylmethane are the main substances released. The workers feel awful during the working time. Gas chromatography (GC) equipped with FID was used to measure the indoor concentration of the above toxic chemical substances in this work. Results show that the concentration of 1, 1-Diphenylethane and 4-Methyldiphenylmethane is up to 70.478 and 8.844mg/m³, respectively, and the concentration of the Diphenylethane is ten times higher than the limit values of Benzene and a part of its derivatives. Further observation indicated that the air change rate is only one time per hour in the workshop and the air distribution may not satisfactory.
