Correct answer: That\u2019s right, all dust is potentially bad for our health, especially in high concentrations and, for this reason, it\u2019s best to minimise our exposure. However, some kinds of dust we may encounter at work are more dangerous than others. For example, the tiniest particles of crystalline silica dust are particularly dangerous \u2013 the respirable fraction.<\/p>

Incorrect answer: Not quite. All dust is potentially bad for our health and, for this reason, it\u2019s best to minimise our exposure. Larger particles are expelled by the body\u2019s natural defences after limited exposure, but finer particles can penetrate deeply into our lungs. The smallest fraction of Respirable Crystalline Silica (RCS) can cause lung irritation and long term health impacts.<\/p><\/div><\/div>\n<\/div>\n\n\n\n
