A. Blood lead levels requiring employee removal. (Level must be confirmed with second follow-up level within 2 weeks of first report.)
	1. ≥60 μg per dL (2.90 μmol per L) or average of last three samples or all blood samples over previous 6 months (whichever is a longer time period) is 50 μg per dL (2.40 μmol per L) or greater unless last blood sample is 40 μg per dL (1.95 μmol per L) or less
B. Frequency with which employees exposed to action level of lead (30 μg per m3 TWA) must have blood lead level checked. Zinc protoporphyrin test is also strongly recommended at each occasion that a blood lead level is obtained:
	1. Last blood lead level is less than 40 μg per dL (1.95 μmol per L)
		a. Every 6 months
	2. Last blood level is between 40 μg per dL (1.95 μmol per L) and level requiring medical removal (see A above)
		a. Every 2 months
	3. Employees removed from exposure to lead because of an elevated blood lead level
		a. Every month
C. Permissible airborne exposure limit for workers removed from work due to an elevated blood lead level (without regard to respirator protection)
	1. 30 μg per m3 per 8 hour TWA
D. Blood lead level confirmed with a second blood analysis, at which employee may return to work
	1. ≤40 μg per dL (1.95 μmol per L)
