Understanding the dangers of Ballast Dust

Ballast dust Understanding and handling the risks

While dust is an inherent feature of most construction sites, when it arises from working with ballast it presents particular problems. The granite within ballast typically includes a silica content of around 30%. As a result, dust arising from ballast contains RCS – respirable crystalline silica – which poses a serious threat to health. The quantities of material involved and their movement mean that large clouds of dust containing RCS can be produced.
