ASBESTOS has been found in two tank seals on QCLNG's site on Curtis Island.
Bechtel said the amounts of asbestos were only trace elements and were removed from the site, but an investigation was underway to find out why the suspect seals were used.
Workers were sent a bulletin on Monday afternoon confirming one of the seals in a small vessel on the underside of the compressor deck on train one had an unusual composition, as did a similar seal on train two, both of which were collected and sent off site for analysis.
"We have inspected all of the tanks on site from the manufacturer of the subject tank," the bulletin said.
"None of the other seals on this manufacturer's tanks are suspect."
It went on to say no presence of asbestos had been found in samples from multiple other sources on site that were tested as a precaution.
Bechtel said the appropriate authorities had been notified about the concerns with the two suspect seals and an investigation into where the seals came from was ongoing.
The site preservation team, which found the trace elements, was congratulated on its proactive approach to ensuring and maintaining a safe work site.
