Biased risk assessments can happen when a safety products company, integrator, or solution provider participates in the risk assessment. The participant has a conflict of interest and may steer you towards overly expensive or complex solutions that they want to sell you. Safety product companies have sales targets and you could be one of them. We can solve your machine safety compliance issues, provide unbiased Risk Assessments, or help you develop your corporate Machine Safety and Risk Assessment program.

A multi-national food processing company had a problem. A recent amputation at a U. A summary in our safeguarding audit reports for one plant was as follows:. For the 19 high risk and 8 medium risk poorly guarded machines, action by applying risk reduction measures through the use of the hierarchy of controls was required.

MSS provided a Machine Safeguarding specification for the machines and worked with our client to select qualified local fabricators and integrators that performed the work in an aggressive schedule. MSS provided specifications and consulting services, and our client contracted the fabrication and integration contractors directly, under the guidance of MSS. During the design phase of the Machine Safeguarding implementation, MSS provided safety verification services and detailed design reviews.

Due to the stringent legal requirements and the need for global compliance, the safety design verification included SISTEMA analysis of the functional safety systems. Due to the complexity of the machines and global safety requirements, MSS verified and validated the machine to numerous U. Then, after installation and before placing the machines into production, MSS was contracted to perform safety validation services as required by the standards. During the validation phase of the project, MSS traveled to site to inspect all machine safeguarding and validate the functional safety systems.

This safety validation included all aspects of the safety system, including barrier guards, interlocked barrier guards, light curtains, area scanners, the safety controllers and safety software, safety servo systems, variable frequency safety drives safety VFDs , and pneumatic air systems.

After the machine safeguarding design verification, installation, and safety system validation, MSS was pleased to provide the following data in the executive summary of the report.

By helping you implement the project, we kept the safety project on-track. Our validation testing and detailed test reports provide peace of mind, and evidence of due diligence if OSHA pays you a visit.

A global OEM needed to automate 30 existing manufacturing lines across 12 plants. Six weeks later, the machine builder delivered a seemingly impressive Collaborative Robot assembly system to the plant.

Engineers quickly completed commissioning and the Collaborative Robot system went into production. As the Collaborative Robot worked in close proximity to the plant associates, troubling questions weighed on the project team…. On-site, we inspected the Collaborative Robot, took measurements, gathered observations and findings, validated safety functions, and spoke with various plant personnel maintenance, production, EHS, engineering, etc.

The final report included Observations, Risk Assessments, and specific corrective actions needed to achieve US and global safety compliance. Examples of our findings and corrective actions include:. With corrective actions complete, we re-inspected the machine and confirmed all safety settings. The customer then duplicated the machines and successfully installed the systems at 12 plants globally, knowing the machines were safe and that global compliance was achieved.

Another success story by MSS…. A US manufacturer was attempting to automate a complex task — assembly of an elastic sheet in a complex frame, then cutting it precisely. This process required 16 people across four US plants, and the manual process simply could not keep up with orders.

In addition, due to employee fatigue, quality issues were frequent and senior management demanded a solution. How to develop a custom robot cell and deliver it in a tight schedule. The manufacturer hired a robotics integrator and a brief engineering study determined that speed and force requirements required a high-performance Industrial Robot not a Cobot. Within 3 months, the robot integrator had the prototype system working beautifully in their shop and was requesting final acceptance of the system.

This is when the second problem hit — the US manufacturer experienced a serious robot-related injury. The final report included a formal Risk Assessment, a compliance matrix, our observations, and specific corrective actions needed to achieve safety compliance. With corrective actions complete, MSS re-inspected the machine, verified safety wiring, validated the safety functions and provided a Declaration of Conformance for the robot system.

The customer then accepted the system, commissioned, and placed it into production. The project was then deemed a huge success by senior management. Background: A safety products company was contracted to perform a risk assessment. Result: The most expensive products and solutions were recommended by the product company. The client purchased and installed the materials, resulting in an improper application of a safety device.

The hazard was not effectively abated. Machine Safety Specialists specified the correct light curtain and a compliant, cost-effective solution was finally installed.

Safety laser scanners can be installed in facilities where light curtains are not suitable, and the muting function makes it possible to minimize undetectable areas. Safety laser scanners, however, enable flexible and customized configuration of the muted area. With only the exact shape of the item being muted, other open areas that could pose a danger are eliminated.

Safety laser scanners are not restricted by where they can be installed or what areas they can cover. This means safety laser scanners can be used wherever they offer the best protection inside the factory. Multiple protection and warning zones can be set up for each bank. With a maximum of 32 configurable banks, users can select the most appropriate zone by using external signals.

Three levels of control can be set up through selective use of protection zones and warning zones. Safety laser scanners are capable of handling multiple banks, and users can switch between these banks using external signals to select the most suitable protection zone at that particular time.

This is called the bank switching function. Models that can be used to register up to 32 banks allow configuration of one protection zone and two warning zones for each bank. This prevents machine operation with an unintended protection zone selected.

These functions are useful safeguards for automated guided vehicles AGV and collaborative robots cobots. Automated guided vehicles AGV require a safety device that can switch the protection zone according to the surrounding situation. The SZ-V Series and the SZ Series both include the bank switching function for constantly detecting the travel direction of the scanner. The bank switching function is used to specify the protection zones and warning zones configured as banks. By switching banks according to the direction of travel, the safety laser scanner can continuously monitor its surroundings.

This ensures the AGV stops when the safety laser scanner detects a person or object on the course ahead. It also disables AGV startup when near a person or object. Selective use of protection zones and warning zones make it possible to issue an alarm warning whenever a person or object enters a warning zone, and stop the AGV if a person or object enters a protection zone.

Safeguards for six-axis robots without safety fences. Entering the movable range of an operating robot with no safety fence is extremely dangerous for operators, so strict safeguards must be put in place. It is possible to control the system so that the robot does not start up until all operators are outside of the protection zone. Startup can also be prohibited while an operator is working in the movable range.

In situations where robot operation is necessary even while an operator is in the protection zone, such as for maintenance, the safety function can be temporarily disabled.

Such a control system can be created using a communication-capable scanner. Safeguards for rolling machines: Unwinding devices. With most rolling machines, operators manually feed the materials, set up the rolls, and clean the machine.

For this reason, reliable safety measures are necessary to ensure that the roller is completely and unmistakably stopped while operators perform work.

Rolling machine startup is disabled while the operator is inside the safety perimeter. Combine this with a safety interlock switch GS Series , this creates a safety system that prevents rolling machine startup until the operator finishes working inside the safety perimeter, leaves the space, and closes and locks the door again.

A safety laser scanner serves three major purposes: area protection, access protection, and collision prevention. For area protection, the safety laser scanner is installed horizontally to monitor a hazardous zone.

For example, area protection may involve checking for any remaining operators and preventing the machine from being restarted if detected. For access protection, safety laser scanners are commonly installed vertically to detect access into a hazardous zone and stops machine operation if entry is detected. Safety laser scanners can be used in place of light curtains, which need pillars on both sides of the entry point, to detect access.

Collision prevention is a function used when the safety laser scanner is installed on an automated guided vehicle AGV. The scanner detects nearby workers to prevent collisions. Safety laser scanners can also be used for collision prevention with rail-guided vehicles RGV and forklifts.

Safety laser scanners are reflective sensors that use laser light. They can be installed anywhere and for any protection zone. This gives them an advantage over light curtains in terms of available installation locations. Aligning the optical axis during installation is also incredibly easy. Even complex-shaped protection zones can be easily set up using the intuitive software.

Additionally, compared with safety mats, safety laser scanners are not at risk of being damaged from falling workpieces. Safety laser scanner protection zones can be set freely, so layout changes can be implemented with ease. When changing the layout, there is no need to have a stock of safety mats of different sizes and shapes for creating different protection zone shapes.

Compared with other safety devices, safety laser scanners are less restricted in terms of installation location and protection zones.

Installation is easy and the risk of failure is minimal, making them safety devices that offer efficient safeguards. One of the most common causes of accidents near robots is activation reactivation of the machine while someone is still inside the safety fence.

Blind spots tend to increase near larger robots, and the need for measures to secure such blind spots is clearly defined in various standards including ISO Using a safety laser scanner makes drawing up a protection zone simple.

The functions for easily drawing zones according to a current layout and for drawing zones customized to a specific location both allow for simple protection zone setup. The maximum protection zone is also large. Using multiple safety laser scanners can completely eliminate blind spots.

With the help of such functions, safety laser scanners can easily detect workers without having to change the layout around the robot. Certified safety sensors that use laser scanners are called safety laser scanners.

To become a certified safety laser scanner, devices must meet the following international standard requirements. This section offers a closer look at the certified standards of these two sensor series.

This product safety standard focuses on electro-sensitive protection equipment ESPE , including safety sensors such as safety laser scanners, that electrically detects human bodies and outputs control signals for protecting workers while a machine is in operation. Safety sensors are classified by safety level, and each type must incorporate a design and structure that prevents hazardous situations in the event of a component failure.

Type 4 devices offer the highest level of safety.
