A portable detection system (10) for hazardous materials including explosives and infectious or hazardous biological agents readily adapted to conventional mail collection boxes (12), rural mailboxes (100) and the like. The system includes a fan (14) and a sensor (16). The fan (14) provides sufficient airflow to circulate the air within a mailbox such that the internal air after coming in contact with the contents is directed the sensor for analysis. The air quality can be determined visually (137), audibly (138), or electronically (139). Consequently once such detection is made and the air is verified as being safe, the contents can be removed safely. If it is determined that the air contains some type of hazardous material, further steps can be taken to specifically locate the source of such hazardous material. An alternative embodiment includes a filter (15) to improve fan efficiency.
