Integrated Risk Management’s ability to measure alertness simply changes how fatigue will be managed in the workplace forever.


Integrated Risk Management has the ability to actively measure and record an operator’s level of alertness—continuously and objectively. This ability is available for the very first time, and not only facilitates proactive mitigation activities with visual and audible alerts at the onset of drowsiness, but it also provides crucial monitoring input. Crucial monitoring input is used in both post-incident root cause analysis and optimizing tailored corporate fatigue management policies. Traditionally, alertness levels and workplace fatigue have not been easily measured or quantified. This fact has created hurdles for risk managers as administrative solutions alone have limitations—it’s difficult to manage what you cannot objectively measure. Integrated Risk Management’s ability to measure and record an operator’s physiological state of alertness is unprecedented in managing workplace fatigue. Simply, Integrated Risk Management makes workplace fatigue risk management easier, effective, and a solid return on investment.

FATIGUE RISK ASSESSMENTS Integrated Risk Management provides the most accurate and comprehensive fatigue risk assessment available in the world today. The risk assessment incorporates a human factors analysis in conjunction with objective fatigue risk profile data. The ability to overlay objective data with human factors analysis facilitates the most comprehensive assessment of an organization’s fatigue risk. The accuracy and understanding provided within the assessment allow for the development of appropriate administrative and engineers controls to minimize risk to an acceptable level. OPTALERT is the world leader in alertness detection technologies. Founded by Dr. Murray Johns, a world-renowned sleep expert, the company developed the OPTALERT Alertness Monitoring System—the only scientifically validated system that measures an operator’s level of alertness continuously and objectively.

Johns Drowsiness Scale Correlation to Individual’s Drowsiness Risk Profile

Johns Drowsiness Scale Dr. Murray Johns, over 15 years, developed an objective scale to measure alertness. The scale is the most effective means to manage fatigue in the workplace. The Johns Drowsiness Scale (JDS) measures an individual’s drowsiness level on a scale from 0-10 (0 being very alert and 10 being very drowsy). This JDS score directly correlates to an individual’s risk of having a drowsy incident, similar to an individual’s risk profile as their blood alcohol level increases. The JDS is the only scientifically validated scale for drowsiness in the world.

Continous Cycle of Improvement (PDCA) With the ability to measure, comes the ability to manage. Now fatigue risk can be objectively measured, metrics and risk profiles can be analyzed, and appropriate adjustments to the overall corporate strategy can be made. These adjustments can then be measured again, continuously lowering risk exposures as a company’s environment and operations change. This begins the continuous cycle of improvement, strengthening the effectiveness of the corporate fatigue strategy and lowering the company’s risk exposure to fatigue.

The OPTALERT Alertness Monitoring System consists of the OPTALERT Glasses and a visual indicator mounted on the dash of the vehicle or workstation. Behind the scene is a small and durable processor. All components are easily installed within all types of vehicles or vigilant control stations. OPTALERT’s patented technology continuously measures drowsiness by using invisible pulses of light to detect eye and eyelid movement. Tiny light emitters and receivers are built into the frames of the OPTALERT Glasses worn by the driver or operator. The glasses are connected to the OPTALERT Vehicle System, which processes the information for instant display and real-time communications to accountable parties.

FATIGUE RISK MITIGATION OPTALERT’s technology provides risk mitigation on three levels.

Level 1

Frontline Risk Mitigation

Simply allowing an operator to continuously see their alertness level with the visual indicator enables the operator to actively manage their drowsiness by adjusting their actions to keep risk within acceptable levels. Empowering operators to manage their drowsiness, coupled with visual and audible alarms as drowsiness levels increase, provides frontline risk mitigation before risk can escalate to dangerous levels.

DATA CASE STUDY A major mining company in Australia incorporated OPTALERT as part of their fatigue management strategy. Their night heavy haul shift began at 7 pm with operators taking their first break at 11 pm. As the risk profile for that shift began to build, it was very clear that the risk level of the entire shift spiked at 10:30 pm to an unacceptable level. With this information,

the mining company adjusted their shift schedule to begin a break at 10:30 pm. This simple change significantly lowered the overall risk profile for the night heavy haul shift. This is a

Operators JDS scores and risk profiles can be transmitted in real-time to accountable parties, such as control rooms and/or supervisors. The ability to monitor an entire fleet’s risk profile at any given moment allows accountable parties to take suitable actions before risk escalates. The real-time monitoring system provides a continuous snapshot of the company’s entire fatigue risk profile from an online source and can be provided to any accountable party anywhere in the world.

Quantitative Reporting, KPIs & Benchmarking

Quantitative reporting provides the ability to analyze fatigue risk profiles on many levels, including individual operators, shifts, operations, locations, and other key data. Identifying unacceptable risk profiles with objective data, for the first time allows, us to make proper adjustments and changes to policy including scheduling, training, monitoring, etc. The ability to identify unacceptable risk profiles improves the overall fatigue strategy—reducing risk and improving productivity. These risk profiles also enable KPIs and benchmarking to establish base lines for acceptable risk and allow performance to be measure.

lowering risk, and improving productivity.

OPTALERT’s technology offers the ability to objectively measure and record an operator’s level of alertness, and thus enables definitive rootcause analysis in post-incident investigations. The ability to determine definitively drowsiness as a contributing factor in an incident has been elusive for safety professionals to-date. Not anymore.
