A walk through survey was conducted at Travenol Laboratories, Inc. (SIC-2834), North Cove, North Carolina where polyvinyl-chloride intravenous bag sets were manufactured. Dielectric radiofrequency (RF) heat sealers were used during the manufacturing process. The only appreciable exposure to which employees involved in the heat sealing operation were subjected during the survey appeared to be RF waves. Examination of the 19 heat sealers used indicated that two of the machines generated incident radiation of 0.65 and 2.85 amperes squared/meter squared (A2/m2) which are both above the current OSHA standard of 0.25A2/m2. Magnetic fields generated by the other heat sealers ranged from nondetectable to 0.171A2/m2 and the electric fields ranged from nondetectable to 20,800 volts squared/meter squared (V2/m2) with an average of 4,110V2/m2. Records kept at the firm were sufficiently detailed and accurate to permit an epidemiological survey, but almost all exposures were less than 10 percent of the current allowable standards. The authors conclude that this specific facility should not be included in the overall study cohort to review the effect of exposures to RF radiation on heat sealer operators.
