This study was intended to measure the effectiveness of ventilation systems in removing airborne contaminants produced by arc welding in vocational agriculture laboratories in Missouri. It was found that most schools did not meet the minimum Occupational Safety and Health Administration standards. (SK)

Sensitivity to the sounds and noises affecting the operation of industrial arts and vocational education programs is imperative for the professional educator. All teachers need to develop the capacity to "tune-in" on noises or sounds which signify prompt reaction to a hazardous condition or an unsafe act. (CT)

This article brings to the attention of chemists the toxicological properties of several important classes of organic compounds. (BB)
