At approximately 8:30 p.m., Employee #1, who works for a manufacturer that makes multilayer circuit boards by a multistep dip operation, inadvertently mixed 55 gal of 50 percent hydrogen peroxide into 110 gal of 30 percent formaldehyde. This resulted in a carbon monoxide and hydrogen release. The facility was evacuated and the local fire department and ambulance responded. Employees #1 through #14, three of whom were from two temporary employment agencies, were treated for inhalation and released. Employee #1 evidently had not looked at the label on the 55 gal drum. Both hydrogen peroxide and formaldehyde are in similar black 55 gal poly drums with labels on one side.
