Health Department “action level”
Sir, — Your article on the problems of silica dust and lead absorption in foundries (“The Press," September 2) misrepresents the effect of the Health Department’s “action level.” When a certain level of lead is detected in the red blood cells of foundry workers our department inspects a factory with the purpose of finding and applying remedies to remove or moderate the lead source and to reform attitudes and work practices. This is the "action level." If a higher level is detected in a foundry worker, this may exceed what is called the “suspension level” and the worker is suspended until the level falls. Suspensions are rarely called for. The distinction between these’levels is important and should not be misunderstood. — Yours, etc., (Dr) W. A. MALPRESS, Medical Officer of . -Health. Christchurch. , September 2, 1982. ..•
