An incinerator is about to be removed from an area within a building. We have
had a dust survey done and the results have said that there is a large
quantity of Lead dust as well as other metals (Manganese, Zinc, Copper). The sort of result you would expect from incinerator dust.
The only reference in EH 40 is dust of any kind i.e. (10 mg Inhalable, 4 mg respirable)
The CLAW regs gives no indication of Lead dust limits.
Can anyone give advise on things to consider apart from the obvious control measures of things to consider.
The company who will be doing the removal will send the method statement
and risk assessment to me which I will scrutinise before work commences.
Your help will be much needed

Manganese and copper are both listed in EH40/2005; see CLAW Reg 2 for the lead in air limit.

There is no direct translation. If the dust contains lead at 1156 mg/kg, the concentration of the metal in the air will depend on how much of the dust gets airborne. For example, if the total dust concentration is 10 mg/m3, the lead concentration would be a bit less than 1/10 of the lead in air limit; but, if the total dust concentration was 1 mg/m3, the lead conc. would be a bit less than 1/100 of the lead in air limit.
