Machine guarding overview November 19 2024 | Blog Post, Venus Automation When considering hazardous areas on machines such as crushing/impact, entanglement, laceration, stabbing, and abrasion hazards, it is important to understand two main ways to guard operators from interacting with them. The first option, which we have discussed extensively, are electro-mechanical solutions. These include electrical interlocks, mechanical interlocks, safety switches (both contact, and non-contact), and photoelectric sensors. The second, often more simple solutions lie within permanent and fixed guarding. Permanent machine guarding, as the name would suggest, is an inherent guard built into the design of a hazardous machine. For example, an AC motor has a spinning shaft that is hazardous once it reaches its operating speed. They can pinch, cut (if there are blades/gears), and generally harm operators. To mitigate this, a metal sheet welded onto a machine to form a barrier, or housings between a motor and a gearbox would make the shaft of an AC motor inaccessible when assembled. Permanent guards are integrated into the design and cannot be removed. Generally speaking, the use of  permanent guards in hazardous areas is not feasible if the machinery contains serviceable parts, and thus requires maintenance. This is where fixed guarding becomes valuable. Fixed guards are considered as semi-permanent physical barriers between operators and hazards. They include fencing, tunnel guards, or roller cover guards. If these fixed guards are not interacted with frequently, this form of fixed guarding is sufficient. However, in the case of access doors, panels, gates, and moving guards that allow conditional access to a hazard (it should not open when the machine is running), interlocked guards are required. This blog post will briefly explore some machine guarding options – two fixed, and two interlocked. Fixed Guards – Axelent Fencing Fencing is a crucial form of fixed guarding in the industrial workplace. Fixed guarding through fences and barriers prevent access to hazardous machinery, and prohibit operator-machine interactions during dangerous operations. By creating a physical barrier, fencing ensures that workers maintain are safely distanced from hazards brought about by moving heavy machinery. There are different types of fences, including perimeter fences and distance guards, which are strategically positioned to limit one’s reach into a hazard. Furthermore, horizontal and vertical spacing of mesh is also a factor that is considered by fence guarding designers. Reaching in through a grille, and through square/circular appertures (the gaps in fences) all have acceptable and expected measurements such as the distance from the danger point (safety distance), along with the separation between each line of fencing. Beyond this, fixed guard fencing with access points may also be designed to limit movement from operators so that entry of a limb into a hazardous area is limited. Examples of this would be adding an arm support that extends to joints depending on the angle/range of the hazard. For example, these guards can support up to the knuckle joint, the wrist joint, or the shoulder joint. Fences are often installed based on reach distances—guidelines that determine the minimum safe distance from the hazard based on ergonomic factors and the likelihood of someone attempting to lean over or reach through the fence. Axelent’s X-Guard safety fencing system is a versatile and modular solution designed to meet the latest safety standards, including the Machinery Directive 2006/42/EC. This system offers various configurations for effective machine guarding, including mesh panels, posts, and door options (hinged or sliding). It ensures comprehensive perimeter protection, preventing   access to hazardous areas while maintaining visibility and accessibility for maintenance. Additional accessories, like cable trays, enhance functionality and installation efficiency, making X-Guard an adaptable choice for industrial environments. Fixed Guards – Concertina Roller Guards Another option for fixed guarding that presents itself in industry is roller guards. Roller guards are ideal for tight, limited spaces, and are also capable of expanding (and locking in place) and retracting. This enhances the flexibility of these guards, enabling hazardous areas and environmentally sensitive moving parts to be effectively fenced-off from operators. However, since they can retract, Concertina guards do not limit the ability for operators to remove the cover guards to carry out maintenance on any serviceable parts. Commonly used on fitting, turning, and CNC machine tools, Concertina guards are a durable ‘curtain’ type of guard that shield contaminants like dust, debris, and corrosive/caustic liquids from entering sensitive machines and sensors. When rolled up, Concertina guards are compact and low-profile; but can always be expanded into their full size. Typically comprised of a metal (most likely aluminium or steel) housing and coated fabric, Concertina guarding is chemically inert, and resistant to oils, acidic, and basic liquids. The end tabs of each roller are often some form of metal cladding, enabling the guards to be bolted into a desired spot for more permanent guarding, while also providing protection from the edges of the roller fabric from fraying. Enhancing their flexibility even further, Concertina roller guards are made to customer specifications, allowing them to be made to suit whatever measurements and spaces the customer requires. Overall, this form of fixed guarding ensures cleanliness, precision, and safety of machine operation. Concertina roller guards contribute greatly to workplace safety by barring operators from hazardous parts. Machine Guarding: two-hand controls Introduction When fixed guarding is less viable/sufficient to protect workers from hazards, different approaches need to be taken to guard operators in other ways. Not unlike fixed guarding methods, some electro-mechanical safety solutions also aim to inhibit the movement of machine operators. To achieve this, two-hand control systems have been developed. Similar to AND gates in Boolean logic, a two-hand control needs an operator to depress both buttons to enable continuity of power flow. Similar to fencing or roller guards, a two-hand control restricts the movement of an operator to only within a tight radius around the machine. Typical Applications Typical applications for two-hand controls as a form of machine guarding include: Hydraulic presses, punches, and stamping procedures Cutting equipment such as automated shears/guillotines Packaging/clamping/sealing machinery Press brakes and metal bending machinery Injection moulding machines. Two-hand controls are useful when an operator’s involvement is essential to start/stop a machine; enhancing safety by enforcing deliberate engagement from a safe distance. Limitations Limited Hazard Protection: While two-hand controls do ensure that an operator’s hands are kept safe, it is important to understand that
