TORRANCE, Calif. (AP) - Tests on dust released during an explosion at a Southern California oil refinery show no serious levels of dangerous materials.
The South Coast Air Quality Management District tested material that fell on cars and the ground after Wednesday's blast at the ExxonMobil refinery in Torrance.
The results, released this week, found the samples contained fiberglass, aluminum, silicon and lower levels of other metals.
But there was no arsenic and only traces of toxic hexavalent chromium.
ExxonMobil officials earlier said the material was might cause skin, throat and eye irritation but wasn't expected to be hazardous.
The AQMD testing also found no serious air pollution from the explosion, which slightly injured four people and heavily damaged equipment.
The blast remains under investigation.
