• Description:
  A study was made to document and evaluate effective techniques for the control of potential health hazards at Sims Radiator Repair Shop, Chamblee, Georgia. This radiator shop repaired automotive and small truck radiators. In July of 1990 the two radiator repair workstations were moved to the south wall of the shop and a ventilation booth was build to enclose them. The booth measured 4 feet deep by 11.3 feet wide by 9.3 feet high. Air was exhausted from the booth directly to the outside. There were no air cleaning devices on the exhaust stream. A fan produced an average airflow of 250 feet per minute (fpm) through the enclosure opening. NIOSH researchers modified the booth by placing a sheet of plastic across the bottom 3.6 feet of the front opening, reducing the height of the opening to 3.75 feet and increasing the face velocity through the opening by about 75fpm to 260fpm. The control booth cost about 1,100 dollars per workstation to construct and make operational. The average time weighted average lead (7439921) concentration prior to installing the control booth was 98 micrograms/cubic meter in 1989. After the control booth was installed this level dropped to 13 micrograms/cubic meter, a 87% reduction. This affordable ventilation control system could be used by most radiator repair shops, but is recommended primarily for locations where the winters are relatively mild. The high volume of air exhausted requires large amounts of heated make up air in the winter months which could be costly.
