Descriptions of cosmetic items with personal safety devices are disclosed herein. In some embodiments, the cosmetic items hold personal beautification products such as makeup. In some embodiments, in addition to makeup, the cosmetic items also include a testing assembly which indicates the presences of specific chemicals mixed in liquids such as alcohol or water. In some embodiments, the cosmetic item includes a computer code trigger which initiates an emergency system. In various embodiments the computer code trigger takes the form of a button or printed computer code, and may include a wireless transmitter for sending signals to one or more computers.

A chemical release detection system includes a camera, an output control member, a mitigation member, and a controller in operative communication with the camera, the output control member, and the mitigation member. The camera is configured to detect a chemical release. The output control member is configured to generate commands. The mitigation member is configured to reduce risk generated by the chemical release based on the commands by the output control member. The controller is configured to notify a user of the chemical release, and provide an origin of the release and a direction of the release. The controller controls the operation of the output control member and the mitigation member.

In a system and method for detecting carbon dioxide in an enclosed volume, a CO2 detection system is triggered to awaken from a deep sleep state. Once awake, the system queries system sensors to determine the current system parameters, including current CO2 level and temperature. Current and expected CO2 decay rates are calculated, and the system determines whether the current CO2 decay rate is within an expected normal range for an unoccupied enclosed volume. If the volume is static, i.e., not moving, and the CO2 rate is rising and the temperature is rising, a series of alerts are sent to contacts previously set up by the user. If the alerts are not cleared by a user, emergency management personnel are notified.

For various political, commercial and humanitarian reasons there is a desire to detect intrusion of stowaways into lorries and other freight vehicles. Many traditional intrusion detectors operate on the bases of detecting an increase in carbon dioxide within a space as indicator of presence of a human. A problem arises when the freight vehicle is carrying perishable goods such as fruits and vegetables which give off CO.sub.2 as they perish which makes it difficult to reliably attribute the cause of an elevation in CO.sub.2 concentration.

An embodiment of the invention overcomes this problem by detecting a sudden decrease in CO.sub.2 concentration within the freight vehicle from a concentration that is much elevated from a background atmospheric concentration of around 400 ppm. This sudden decrease can be attributed to opening of a door of a trailer allowing the escape of CO.sub.2 that has built up as the freight perishes.

A system for redundantly detecting a gas is provided. The system includes first and second series-connected gas sensors and a signaling module. If both gas sensors are functioning normally, the signaling module provides an alert when both gas sensors detect a predetermined gas concentration. If however any one of the gas sensors is experiencing a fault condition, the faulty gas sensor's alarm is shunted by operation of a fault relay, and the signaling module provides an alert when the non-faulty gas sensor detects a predetermined gas concentration. If both gas sensors are experiencing a fault condition, both gas sensors' alarms are shunted by fault relays, and an audible and/or visual alert is generated by the signaling module. Embodiments of the present invention are well suited for industrial facilities, manufacturing facilities, research and development laboratories, and other locations where unsafe gas concentrations may become present.
