Product Information and Safety Warning

At Walker Quarries, safety is a core part of our operations — from extraction through to delivery. We provide detailed safety information and Material Safety Data Sheets (MSDS) to ensure our customers, contractors, and staff are fully informed when handling quarry materials. Our guidelines include potential hazards, recommended protective measures, and safe work practices to minimise risk during transport, storage, and use.

1. Crystalline silica in dust or respirable form (described as Microcrystalline Silica (respirable crystalline fraction) (“silica dust”) can be generated when quarry materials are crushed, cut, drilled, sawed, broken up, ground or transported.
2. Silica dust (so described) is classified as a hazardous chemical by Safe Work Australia. Cystalline silica is also listed in Schedule 14 the Work Health and Safety Regulation 2017 (NSW) as a hazardous chemical that requires health monitoring.
3. Appropriate respiratory protective equipment (RPE) must be used in accordance with AS/NZS1715:2009 and A/NZS1716:2012 when working with or near silica dust to minimise the effects of potential exposure.
4. Exposure to high levels of silica dust can irritate the skin, eyes and throat. Prolonged or repeated exposure to high levels of silica dust can lead to lung disease and cause cancer. Steps should be taken to wash or rinse any affected areas of the body and move straight to fresh air. To prevent extended exposure appropriate RPE and, if necessary, other personal protective equipment (PPE) should be used at all times.
