NOTE:   Airgas will not change these requirements because of urgency, an expedited payment request or because of a "secret" or "confidential" situation.  If you are asked to circumvent these requirements, please alert your Supervisor or Compliance and Controls immediately as this may be a fraud attempt.  If fraud is suspected, the vendor shall be placed on a payment block until a thorough investigation is concluded.
