VTHC Exposure Standard - 0.025mg/m3 as an 8hr TWA.
Victorian Trades Hall Council has released an approved safety standard for silica exposure.
The United States have implemented a silica dust exposure standard of 0.025mg/m3 as an 8 hour time weighted average. We don't think it's acceptable that Australian workers are expected to tolerate up to four times that amount. So we're changing it.
The OHS team at Victoria Trades Hall Council recently produced a webinar with industry experts on silica, where it's found, the damage it can cause and the protective actions that can be taken.
