• Very toxic.
• Toxic
• Harmful
• Corrosive
• Irritant.

  1. 10 mg/m3 as a time-weighted average over an 8-hour period of inhalable dust, or
  2. 4 mg/m3, as a time-weighted average over an 8-hour period, of respirable dust.
  Which, not being a substance falling into any of the above mentioned categories, because of its chemical or toxicological properties and the way it is used or is present at the place of work, creates a risk to health.

There are currently- 9 (Nine) Classes into which the above mentioned fall within and for a better explanation, please click on the relevant navigation bar on the left to view the appropriate Chemical Class listing.
