The Postal Service has recently issued two MMO's addressing two different safety hazard issues on the APPS machine. One deals with an electrical hazard, the other addresses the potential for unexpected startup of induction belts. These are not just Maintenance Craft issues. Anyone who works on the APPS should be aware of these potential hazards. Please Note:An important correction has been made. MMO-067-08 regarding unexpected 70 volts power contained an error. MMO-070-08 has been issued to supersede MMO-067-08.
