Interlocked guards are safety devices that are designed to prevent access to a hazardous area or machine until certain conditions are met. These guards typically consist of physical barriers, such as gates or doors, that are equipped with interlocking mechanisms. These mechanisms are designed to prevent the guard from being opened or bypassed while the machine is in operation.
Interlocked guards are an important safety feature in many industrial settings, as they help to protect workers from the dangers of moving machinery and other hazards. By preventing access to hazardous areas, interlocked guards can help to reduce the risk of accidents and injuries.
There are a variety of different types of interlocked guards available, including mechanical, electrical, and electronic systems. Each type of interlocked guard has its own advantages and disadvantages, and the best choice will depend on the specific requirements of the application.
Some common examples of interlocked guards include safety gates on conveyor belts, interlocked doors on machinery, and safety switches on power tools. These guards are typically designed to be easy to use and maintain, while still providing effective protection for workers.
Overall, interlocked guards are an important safety feature in many industrial settings, and can help to prevent accidents and injuries. By ensuring that workers cannot access hazardous areas while machinery is in operation, interlocked guards can help to create a safer work environment for everyone.

Interlocked Guards
Interlocked guards are protective devices used in machinery to prevent hazardous situations by preventing access to hazardous areas while machinery is in operation or before it is put into motion. They are designed to interlock with the machine's energy sources, ensuring that the machine cannot be operated until the guard is securely in place, and that the guard cannot be removed while the machine is in operation.
Types of Interlocked Guards:
- Mechanical Interlocks: Physically prevent access by connecting a guard to the machine's motion system. When the guard is not in place, a mechanical linkage prevents the machine from operating.
- Electrical Interlocks: Utilize electrical components to detect the presence of the guard. If the guard is not securely in place, an electrical circuit is opened, preventing the machine from starting or continuing to operate.
- Hydraulic Interlocks: Similar to electrical interlocks, they use hydraulic components to detect the guard's position and prevent machine operation if the guard is not engaged.
- Pneumatic Interlocks: Employ compressed air to detect the guard's position and interlock the machine's energy sources accordingly.
Benefits of Interlocked Guards:
- Enhanced Safety: Interlocked guards provide a high level of protection by preventing unauthorized access to hazardous areas, reducing the risk of injuries or fatalities.
- Machine Integrity: By preventing the removal of guards while the machine is in operation, interlocked guards protect the machine from damage and minimize the risk of malfunctions.
- Legal Compliance: In many jurisdictions, interlocked guards are required by law for machines that present hazardous risks.
- Increased Productivity: By preventing machine downtime due to accidents or maintenance, interlocked guards can contribute to improved productivity and reduced operational costs.
