TRANSFORMER OIL Usage And Synthesis

Definition

TRANSFORMER OIL is a complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C15 through C30 and produces a finished oil with a viscosity of less than 100 SUS at 100.degree.F (19cSt at 40.degree.C). It contains relatively few normal paraffins.

Flammability and Explosibility

Non flammable

Safety Profile

Confirmed carcinogen with experimental neoplastigenic data. Low toxicity by ingestion and skin contact. A severe skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

Toxics Screening Level

Hydrotreated light naphthenic distillate had an ITSL of 16 μg/m3 with annual averaging established in 1999, which was based on a rat LD50. The ITSL is being changed to match the generic oil mist ITSL of 50 μg/m3 with 8 hour averaging, because the TLV based screening level is higher in the screening level setting priority than a screening level based on an LD50.
