Heuser Tetra Cthjrl Lead rrermency - Totra Lthyl Lead Examinations ve recently discussed changing the fre quency of the Tetru thyl Lead, examinations from once each three weeks to once each four weeks, shls '.'ill facilitate the ease with which the exam ination may be performed since the Tetra Lthyl Load area Is now working four shifts and since the individuals will rotate on the day shift once each four weeks. I have discussed this suggestion with Management and with Dr. Tehrm&nn, the Medical di rector. They are in agreement with this plan. Le feel certain that, this will give us sufficient Information to follow the health pic ture of the Tetra- Lthyl Lead group. TDDICAL alPAHThloT < (&tr~-1L^A--3 KJ * maw xe 1*' r< N9530
