As we look back on the year that was; Australia has yet another Prime Minister, the newest reality TV star has found another love, and China has set up a ‘ban’ on the importing of recycled wastes under the Blue Sky/National Sword program.
It means, import restrictions imposed have excluded almost 99% of the recyclables that Australia previously sold to China.
This excessive amount of potentially dangerous (when accumulated for long periods of time) recyclable waste products are piling up adding pressure on recycling facilities, local councils and federal government to implement immediate changes to cover the backlog.
We start at ground zero: the recycling facilities. However, with increased volumes and sorting of recyclables, there becomes potential new risks in the workplace such as exposure to airborne dust (in addition to space/stockpiling of materials leading to other risks such as fire, resources to handle the increased/residual loads, lack of technologies to the increased recyclables loads,etc).
The Answer —> Obtain the Data First!! E.g. Airborne dust workplace testing.
Recently, a domestic kerbside and commercial recycling company wanted to know the dust levels in their working environment as it had never been tested before and this is also based on their (OHS) legal requirements.
A sampling plan was constructed and deployed by placing personal (inhalable) dust monitors including filters on various personnel within the plant after communication to them as to why we were doing what we were planning to do.
Personal air monitoring identified exposure to airborne dust particles to be below the respective Safe Work Australia Time Weighed Average (TWA), indicating there was no known immediate risk.
Although dust levels could vary from day-to-day depending on activities performed, it was recommended that appropriate personal respiratory protection should be used within processing areas (and follow up monitoring pending changes to the workplace – e.g. increased materials’ loads, increases in the number of personnel, change in legislation, etc).
If the TWA had been exceeded (or approached it), the following control hierarchy level would have been considered (by Helia EHS in consultation with the client) in terms of recommendations being put forward to the client.
