FEATURE SAFETY IN ENGINEERING Boulting launches new hazardous


area inspection software E


ngineering solutions provider Boulting Ltd, has launched a new


cloud based inspection software that will enable plant engineers to ensure control equipment in hazardous areas is compliant with the latest technical standard, BS EN 60079:17. Boulting has worked in collaboration


with an ATEX certifying body to design and implement the secure, paperless, cloud-based system for maintenance procedures in hazardous areas. The user friendly app provides clear


visibility of hazardous area inspections and incorporates radio frequency identity tags that make it easy to recall information for each device. The system integrates documents required to form an Explosive Protection Document (EPD) for an unlimited number of items, including all area classification documents, risk assessments, equipment certificates and details of all equipment requiring inspection, frequency of inspection and associated drawings. All this information is stored securely in the cloud, with client read only access available. By going paperless and installing the


software on a tablet, engineers are able to navigate vital documents with ease. In addition, the software can help identify trends in any faults that may be common to a specific manufacturer or model. When working in hazardous


environments, which feature flammable gases, vapours or dust, the facility and all the equipment within it must meet BS EN 60079. This British standard is the equivalent of the international standard EN 60079, which sets clear guidelines around zone classification, electrical installation and equipment protection in explosive atmospheres. “As greater demand is placed on


industries such as food and beverage, pharmaceuticals and energy, manufacturing is inevitably put under more strain, meaning processes can often become more complex,” says Josh Groarke, deputy managing director at Boulting Ltd. “At Boulting we are continuously


looking to develop new ways of supporting our clients that go beyond the traditional delivery of a project. The ATEX Hazardous Area Inspection software is one example of us using both our knowledge base and engineering skills to improve overall project delivery.”

EMERGENCY STOP


Parker Hannifin introduces its new externally monitored pneumatic safety exhaust valve for emergency stop and fault conditions


P


arker Hannifin, provider of motion and control technologies, has introduced a new safety exhaust valve that rapidly exhausts compressed air in the event of a fault condition or when a machine has an


emergency stop. The P33 is designed for two channel control architectures and is externally monitored. The new safety valve has a patented fail safe design and is suitable for use in applications up to category 4 performance level e. The P33 safety exhaust valve is available with adjustable soft start and high flow exhaust performance to ensure rapid exhaust of compressed air when required. Designing a control system with a high diagnostic coverage provides a high means of fault detection within the valve, while LEDs provide operators with a clear status indication of sensor power, main solenoid operation and fault condition. The design of the P33 safety exhaust valves has been optimised for long service life (B10d), very high flow rates, high faulted flow rates, compact design and high mean time to failure (MTTF) values. Connectivity is via two M12 connectors that provide solenoid and pressure sensor interfacing. Compatibility with devices from popular manufacturers such as Rockwell, Omron, Sick and Siemens underlines the versatility and flexibility of the valves. Being externally monitored gives greater control at the safety device for the customer’s application. It also reduces the complexity of the machine for start up or resetting of the valve. The fail safe design of the P33 family is maintenance free and requires no additional silencers or mufflers that can clog creating potentially unsafe exhaust conditions.
