Chemical Substance Management for Heavy Electrical Apparatus

Electrical safety standards for electrocardiographic apparatus.

IN 1972, the Committee on Electrocardiography of the American Heart Association (AHA) first published recommendations dealing with electrical safety in electrocardiographic (ECG) and vectorcardiographic (VCG) instruments.' These specifications were restated in slightly altered form in 1975.2 To our knowledge, practically all manufacturers of ECG equipment sold in the United States now follow th...

[Hospital response and medical management in toxic chemical substance disasters].

A hazardous material is defined as any item or agent which has the potential to cause harm to humans, animals, or the environment, either by itself or through interaction with other factors. Toxic chemical substance events are increasingly common events in our modern world. The numerous variables and special equipment involved make effective response to toxic chemical events an especially criti...

Method of and Apparatus for Producing Electrical Impulses or Oscillations

Chemical, Electrical and Magnetic Senses

BASED on preliminary observations that continuous exposure to electromagnetic fields (EMFs) produced an after-effect on human brain electrical activity, the effect of 10 Hz, 1 gauss, on the intrinsic activity of the brain at that frequency was studied. Ten subjects were exposed for 10 min and the 10 Hz spectral power was measured during the 1 min interval following stimulation and compared with...

Chemical Stabilization of Heavy Metals

Heavy metals contamination can be found at battery acid recycling sites, electroplating facilities, military installations, firing ranges, brownfields redevelopment sites, and associated with mining activities. The chemical stabilization process uses non-hazardous chemical binders that permanently stabilize heavy metals. The treated soils contain stable metalreagent compounds that eliminate the...
