What makes you think that motors are safer than pneumatics?
Both can generate a lot of force and a lot of momentum. Both can be made safe, and both can be very dangerous if used incorrectly.
To Sam2197,
both pneumatics and motors can be used equally effective. If you already have pneumatics in your design then adding a cylinder is far less weight than a gearbox and motor ... but if you dont have pneumatics already in your system then the compressor alone may weigh more than using a motor and gearbox.
In short ... it depends
Good luck and let us know what you used.
