This is rediculous. The safety officer needs get his head pulled out! The benches are clearly not the problem. It's the operators that can't think clearly enough not to reach through, or across for that matter, a spinning prop and another that has yet to learn to install his prop securely. This is a classic example of someone so short sited that they "can not see the forest for the trees". If anything needs to be removed from your feild it is the safety officer.
