A company in Perth has been fined $5500 for failing to properly identify the presence and location of asbestos at one of its worksites.

SGS Australia, which has about 70 locations around Australia, pleaded guilty in Perth Magistrates Court last week to failing to ensure asbestos was identified at its geochemical service facility in Queens Park.

A WorkSafe inspection in June 2010 identified asbestos in several parts of the building, which was confirmed when SGS later commissioned an expensive asbestos assessment.

WA's work safety laws require an asbestos register to be established in workplaces that may contain the deadly material, and warning signage must also be placed at areas containing asbestos.

WorkSafe WA Commissioner Lex McCulloch said on Thursday that the case was a reminder to all employers to identify asbestos in workplaces.

"Although the company did make some attempt to address the asbestos issue at its other workplaces, it did not ensure that information about asbestos at its workplaces was passed along to all relevant parties, including any outside contractors who worked at their sites," he said.

"If a building may contain asbestos, everyone having any control has a responsibility to ensure that it is documented - from the employer, main contractor or self-employed person to the building owner or property manager."

Information about the location of asbestos also needed to be made available to anyone who entered a workplace so relevant precautions could be taken, Mr McCulloch said.
