Forget dogs. Robots are humans’ best friends. They may not be fond of fetching twigs or licking your feet, but you can rely on them when it comes to accomplishing tasks half the time.

This is the very reason why they are ideal helpers in factories and other manufacturing facilities. Not only can an industrial robot be designed to finish jobs assigned to ten people, it can be very useful in eliminating hazards that human workers are exposed to in a workplace. This can be anything from heat stress to electrocution to amputation.

But just as robots or robotics systems help reduce or eliminate workplace hazards, they can bring in new ones with their presence. These hazards usually arise with lack of training for employees, as well as improper use of guards.

Here are some general guidelines in reducing or eliminating the hazards posed by robots or robotics systems:

• Employer must insure that the company has a written robotics safety policy that all employees working with or near robots understand.

• The written robotics safety policy must indicate the names of personnel who are authorized to work with robots.

• All robot operators must receive adequate training in hazard recognition, control of robots, as well as the proper operating procedure of the robot and related equipment.

• Employers or safety coordinators must make sure only programmers have access to the work envelope and full control of the robot when it is in teach mode.

• Each robot must be installed according to the manufacturer’s guidelines and applicable codes.

• All robots must be compatible with environmental conditions.

• Power used for the robot must follow the specifications of the manufacturer.

• Each robot must be secured in such a way that it prevents vibration and tip over.

• Each robot must be installed in such a way that hazards like pinch points with robot components and fixed objects are avoided.

• The zones of movement of the robot must be posted on signs and markings displayed conspicuously on floors, walls and the robot itself.

• Stops must be placed on the robot system’s axes. This way, its motions are limited when under rated load or maximum speed conditions.

• Proper lockout procedures must be established and followed for preventive maintenance or repair operations.

• Ensure that robot manufacturer’s preventive maintenance schedule is followed rigorously.

• Before servicing the robot, workers must neutralize first the stored energy devices like springs and accumulators.

• Employees must conduct a periodic check of all safety-critical equipment and connections.
