In industrial and mining settings risk management is not merely a priority; it's a fundamental requirement for sustainable and responsible operational practices. Various risks ranging from machinery malfunctions to human errors are ever present threats. Machine control systems can act as vigilant sentinels, continuously monitoring and managing these threats to prevent potential disasters. Utilising a risk-based approach during the design and integration of advanced machine control systems plays a pivotal role in mitigating inherent operational risks, contributing to the safety and well-being of personnel, equipment, environment and processes.
Risk Management by Design
Risk management by design is more than simply achieving compliance to functional safety standards such as IEC 61508, IEC 61511, IEC 62061, or EN ISO 13849. They can be useful tools but will not be a guarantee that your equipment will be safe to use in your application. Well-designed control systems need to consider the potential for equipment or environmental damage and economic loss, not just human safety. A deep understanding of the ways the equipment will be used and misused and the environment in which they operate is critical to adding layers of protection to the machine design and appropriately testing that they work. The best suppliers will work closely with the end users to gain this understanding before, during and after building their solutions to develop and refine a robust, safe and low risk system.
Uncontrolled Risks
Despite best efforts not every unacceptable risk can always be controlled through OEM engineered solutions. There are risks within the working environment that are simply outside the designers ability to manage, and whilst automation systems are becoming more sophisticated every day it isn't practical or possible to electronically monitor for every eventuality. As such it is necessary to understand and communicate these remaining equipment risks so they can be managed operationally.
Collaborative Human-Machine Safety
Machine control systems are not designed to completely replace human involvement but rather to enhance it. Collaborative safety features ensure that humans and machines work in tandem safely. Collision avoidance systems can detect the presence of personnel or other plant/vehicles in restricted areas, leading to immediate adjustments in machine operations to avoid accidents. Remote operation systems can remove the potential for human-machine incidents altogether. This collaborative approach not only ensures safety but also addresses concerns about the impact of automation on job roles.
The Role of Predictive Maintenance in Risk Mitigation
Beyond immediate response mechanisms, machine control systems contribute significantly to risk management through predictive maintenance. By continuously monitoring the health of machinery and operating conditions, these systems can predict potential failures before they occur. Modern AI can provide deeper revelations that cannot be detected through traditional monitoring methods. This proactive approach minimizes unplanned downtime, reduces the risk of catastrophic failures, and extends the lifespan of critical equipment.
The design and integration of advanced machine control systems is not just about enhancing efficiency; it's a strategic investment in risk management. These systems go beyond the realm of operational control, actively contributing to the safety and well-being of industrial environments. As industries evolve, sophisticated control systems will be an increasingly important tool in managing operational risk. It's important that the right design approaches are applied to make them effective.
