A method for monitoring for the presence of chemical agents comprising the steps of:

• providing an alarm system for portable chemical monitors, comprising a housing configured for attachment to the portable chemical monitor having a twist lock mechanical connector capable of connecting to the portable chemical monitor, a twist lock mechanical connector attached to the housing capable of connecting to a portable chemical monitor, at least three pins mounted within the twist lock mechanical connector, wherein the at least three pins are capable of inserting into the portable chemical monitor, a circuit board supported within the housing and electrically connected to the at least three pins, the circuit board capable of receiving electrical signals from the chemical monitor and, a ceramic disk comprising an indicator means for generating vibrational movement, wherein the vibrational movement provides a audible sound;
• attaching the alarm system to the portable chemical agent monitor;
• transporting the portable chemical agent monitor into an operational area;
• and,
• activating the portable chemical monitor, wherein the indicator means initiates an audible alarm when the portable chemical monitor is in the presence of chemical agents.
