Whether you’re preventatively sweeping a location or responding to an event that’s taken place, knowing exactly the danger you face makes a difference. RAE Systems’ rugged, proven, and integrated multi-gas and radiation detectors meet all military standards and specifications. Easy to maintain in the field and with a global infrastructure for comprehensive support, our products operate on an open platform and can integrate with other third-party systems.

Clandestine Labs

Clandestine labs pose unique risks not only for the general public, but also for the personnel called to investigate and remediate them. Responders need to quickly identify threats that are present. RAE Systems provides the real-time monitors to determine risk by detecting multiple toxic and combustible gases, VOCs and TICs in parts per million (ppm) or parts per billion (ppb). This depth of coverage will help you keep your team members safe while they protect the communities surrounding these sites.

Confined Space Entry

Confined spaces pose a potential threat from poisonous gases and man-down incidents. To comply with regulations and most importantly to protect responders or workers, these spaces must be evaluated before entry. Ongoing, continuous monitoring also offers important safety advantages. With full tracking capabilities, real-time wireless connectivity to a central office, and data logging and recording, you can simplify management and streamline compliance.

In addition to sensors for combustion risk, oxygen concentration, carbon monoxide, benzene and H2S, many of our solutions include a PID sensor, which allows you to check for a wide array of other unknown threats. With the information provided by RAE Systems devices, personnel and supervisors have a clear indication whether or not entry and working conditions are safe at all times.

Emergency Response

In an emergency, responders need to know exactly the threats they face. RAE Systems provides integrated gas and radiation monitoring solutions that can be wirelessly networked together to provide a comprehensive view of potential dangers. Rugged, easy-to-maintain personal monitors, GPS tracking capabilities, and man-down alarms provide data for individual team members in emergency situations. Portable detectors enable you to establish a continuously monitored perimeter around the incident, which helps protect the public and your response teams. And seamless wireless connectivity gives you centralized visibility and fast mobile access to levels and toxicity data via PC, smartphone, or tablet for effective decision making and coordination, even during times of crisis.

Environmental Cleanups/ Remediation

RAE Systems products are effective, reliable, and accurate for all stages of environmental remediation. Portable survey PID detectors provide broad awareness of any harmful VOCs and toxic industrial chemicals (TICs) that may be present. Transportable detectors enable multi-gas monitoring throughout the remediation phase and can be moved and reused on projects as needed. And multi-gas indoor air quality (IAQ) monitors with parts per billion (ppb) capabilities enable organizations to provide higher quality workplace environments.

Our ProRAE Guardian real-time wireless safety system centralizes monitor, GPS, biometric, plume and other data for added safety. This makes it easy to share information in real time with clients, consultants, contractors, and regulators, as well as record data for compliance monitoring. And because RAE Systems is a trusted vendor to the EPA and other environmental agencies worldwide, you can feel confident your real-time monitoring will meet stringent government and environmental requirements.

Our field-proven systems detect a variety of gases and provide around-the-clock detection with multiple audible, visible, local, and remote threat alarms to help maximize safety. With our easy to deploy networks, you can have a solution in place quickly, to help you get producing faster.

Our wireless solutions provide a full gas detection system that is up and running in less than an hour to help you speed rig deployment, minimize downtime, and enable a faster, safer overhaul. RAE Systems monitors are proven, intrinsically safe, and can be used in harsh operating environments anywhere around the rig. RAE Systems’ personal gas detectors can also provide your teams with continuous monitoring to improve safety and streamline compliance.

Fire Overhaul

After a fire has been suppressed and teams engage in overhaul operations to identify potential sources of re-ignition, numerous hazards persist. HCN can remain trapped in the walls and release when cooled. Today’s building materials can cause toxic off-gassing – even when only heated, not burned. Portable, area and personal RAE Systems monitors can help determine which toxins are in the area, and provide the real-time information necessary to decide whether the site needs to be treated like a HazMat situation, or whether it’s safe to remove SCBA.

Leak Detection

Minimize the risk of exposure, explosion, or loss of products with gas monitoring of areas, pipes, valves, and pumps. A comprehensive RAE Systems survey monitor, area monitor, and portable gas detection solution can provide real-time gas detection information. In addition to real-time data, RAE Systems solutions offer XML data output for integration with SCADA process controls, data analytics, and risk mitigation.

Plant Shutdown & Turn-Around

Ensure optimal safety during plant/refinery turnarounds. With onsite contractors, extensive confined space entry activities, and expanded potential for incidents, having RAE Systems’ fixed and portable wireless gas detection solutions can help you maximize turnaround efficiency, reduce downtime, and get back to production quickly.

Our range of wireless, plant-wide gas detection monitors delivers anywhere, anytime detection and can be deployed in a matter of minutes. These systems will help protect your contractors and offer visibility and simplified compliance by centralizing data collection and documentation.

Residential Calls

Residential EMS calls can involve contact with toxic or combustible substances. Frequently carbon monoxide (CO), a by-product of fuel that has been improperly burned can be found in structures. Also paramedics should be conscious of the potential for HCN at a fire scene. RAE Systems single-gas detectors are proven, fast, reliable, and conveniently worn or carried so that responders and EMS personnel can quickly determine whether CO or another toxic gas may be present.

Urban Search & Rescue

When large-scale disaster strikes, urban search & rescue teams can face unexpected exposure to toxic and combustible gases. These teams need to be ready for anything during search & rescue missions. RAE Systems solutions provide the data necessary to respond appropriately. Our multi-agent detectors enable team members to get real-time, detailed data on specific toxic gases, and our patented PID sensors provide broad-based assessment for other VOCs that might be present due to leaks or fire. Portable detection and dosimeters can also provide warning during accidents involving hospitals, research, power, and nuclear facilities.

Worker Exposure

Ensuring a clean and healthy workplace, free from toxins, is a key way to keep workers healthy and productive. RAE Systems provides a variety of options to protect worker safety — from personal monitors that detect even trace amounts of any VOCs or TICs to fixed and semi-fixed multi-gas detectors that provide continuous coverage for your facility.

According to the Centers for Disease Control, healthy workers are more productive. They use less sick time, reducing time off the job. Protecting your workers from exposure to harmful compounds and gases is key to maintaining their health. Workforce protection is also important for your reputation and for compliance with regulations. When you equip workers and managers with wearable personal gas detection monitors, you can help ensure their safety and well-being. Real-time wireless data logging and alarms help you reduce potential exposure, increase effectiveness of incident response, and document long-term exposure risk.
