The Importance of Choosing the Right Machine Safety Devices


Accident and Injury Prevention

These devices serve as a protective shield between employees and hazardous machine parts, safeguarding employees during regular operations. Choosing the proper machine safety devices is essential in preventing accidents and injuries. Your internal machine safety stakeholders can significantly reduce the risk of harmful incidents by identifying potential hazards and implementing the appropriate machine safety measures. 

Enhanced Productivity and Efficiency Safety

Implementing machine safety measures should not hinder productivity. In fact, by incorporating the appropriate machine safety devices, operations can be enhanced and streamlined. When employees feel safe and secure in their environment, they are able to focus on their tasks more effectively, ultimately boosting overall efficiency and productivity levels.

Compliance with Industry Regulations 

Adhering to industry safety regulations is not just a legal requirement. At the end of the day, safety in the workplace is a moral responsibility. Employers must prioritize the safety and well-being of their employees. Using the proper machine safety devices ensures compliance with regulatory requirements and industry-consensus standards and guidelines set by regulatory authorities - fostering a culture of safety in the workplace.

How to Choose the Correct Machine Safety Device for Your Application 

Selecting your application's correct machine safety device ensures a safe working environment. But the process is complex and can be timely if you don't have the internal machine safety and controls expertise. By following these steps as a roadmap, you can begin to grasp the intricacies of selecting the correct machine safety device that perfectly aligns with the unique requirements of your application. Remember, the choice of machine safety components should always prioritize personnel safety and compliance with relevant regulations. If you're unsure about any aspect of the selection process, consider consulting with safety experts or engineers specializing in machine safety.

Identify Potential Hazards with a Risk  Assessment:

Understand the specific risks associated with your machinery and its operation. Contact a trusted machine risk assessment provider for a thorough risk assessment that complies with the regulatory requirements and updated safety standards and guides to pinpoint potential hazards and the areas that require safeguarding improvements. Check out our past blog post, 5 Steps for Improving Machine Safety, for more information on machine risk assessment methodology. 


Analyze Machine Operations:

Analyze how your machinery operates and the potential scenarios where accidents might occur. Consider all possible near-misses or critical situations and plan for them accordingly. For the best results, involve your operators and mechanics in the decision-making process - their firsthand experience and insights can help identify potential safety concerns and provide valuable input on device usability.

 

Consider Application Specifics:

Consider your application's unique aspects, such as the type of machinery, its speed, and the tasks performed. Certain safety devices might be more suitable for specific machines and processes. Remember that compatibility and ease of integration are crucial to maintaining smooth operations.


Ten Common Machine Safety Devices

1. Guarding


Guarding is one of the most common and vital machine safety devices. Guards act as physical barriers preventing direct contact with hazardous machine components. Guards are adaptable to various applications, with sizes and configurations that can be customized to meet specific needs. They are typically constructed with an aluminum extrusion or steel frame, accompanied by a robust barrier made of clear polycarbonate or wire mesh. Allowing for seamless adaptation to meet your evolving requirements.

 

 

2. Safety Interlock Switches


Safety interlock switches are often used in conjunction with machine guarding. These tamper-resistant switches prevent machines from operating when a door or access point is open or removed. They help ensure the machine comes to a halt, providing an extra layer of protection.

 

3. Light Curtains & Laser Scanners

Light curtains and laser scanners use light beams to create an invisible barrier around a hazardous area. When the beam is interrupted, the machine is automatically stopped, preventing access to dangerous zones during operation.

 

4. Emergency Stop Buttons & Pull Ropes

Emergency stop buttons and pull ropes are crucial safety devices that allow employees to halt machinery instantly in emergency situations. They provide a failsafe mechanism that overrides all other controls, enabling a quick response to potential accidents.

 

5. Safety Controllers & Relays

Safety controllers and relays serve as the brains behind the safety control system, coordinating the functioning of various safety devices. They ensure the safe start and stop functions for hazardous machinery, providing an integrated approach to safety.

   

6. Enabling Switches 

User-activated switches become active when a user either squeezes or releases the handle/switch. These switches can operate continuously, enabling manual control of machines, but they are only functional when someone is actively operating them. They can take various forms, such as buttons, triggers on handles, dual-handed controls that necessitate the use of both hands, and numerous other possibilities.

 

7. Energy Isolation Equipment 

The fact that a machine is powered off does not guarantee its safety, particularly when in a vulnerable position, like during maintenance or repair. Unexpected releases of hazardous energy, either gravity, spring tension, or pneumatic or hydraulic energy can lead to disastrous consequences. However, energy isolation devices with lockout equipment applied can provide assurances all potential energy within a system has been controlled or relieved, ensuring no unforeseen release of hazardous energy occurs. 


     

 

8. Indicator Lights

Light and colors serve as rapid methods to convey real-time safety and operational status updates. Lights can function autonomously or be assembled as a tower, delivering exceptional visibility. They can be positioned within hazardous zones and can be tailored to indicate specific attributes needed for your particular application. An elementary illustration of immediate visual safety information is having a red light indicating an active hazard condition and a green light denoting normal operational activity. 

 

9. Safety Mats, Edges & Bumpers 

Safety mats are flexible mats placed on the floor in hazardous areas. They have pressure-sensitive sensors that halt machinery if someone steps on them. Safety edges are strips along moving parts that stop equipment when compressed. Safety bumpers, sturdier versions, are used on mobile machinery to detect collisions and prevent harm. All these devices enhance workplace safety by preventing accidents and injuries.

 

10. MPSA Gotcha Stick 

A Guard Opening Scale, AKA a "Gotcha Stick," is a tool used to ensure machine barrier openings are compliant with up-to-date machine safety standards.The Gotcha Stick physically tests the measurements between guard openings and machine hazards, quickly determining whether or not the guard openings are safety standard compliant. Testing machine barrier openings with a Gotcha Stick helps ensure the barrier guarding and any opening are at a safe distance away from the hazard.


   

 

 


In Summary...

Ensuring the proper integration of machine safety devices is crucial in creating a safe and secure workplace for all. By utilizing the correct machine safety devices, employers can significantly reduce the risk of accidents and injuries, comply with regulatory regulations, and foster a culture of safety and productivity. Each of these machine safety devices, plays a vital role in protecting both employees and equipment, ensuring a safe, secure, and productive work environment.
