"Fit for life" is the first safety measure used by OSHA and this has become an integral part of their rules and standards. The purpose of this safety rule is to define a construction worker as able to do his or her job safely. This is achieved by defining what constitutes a safe work environment.

OSHA defines this environment as one that offers workers' protection from dangerous conditions on the work site. The first safety measures that were instigated by OSHA were safety shoes. These shoes are ergonomically designed shoes that provide workers maximum support while still allowing flexibility. In the past, OSHA did not define what safety shoes were and it varied from region to region. There was no standardization of OSHA safety shoes. This has led to variation in shoe sizes and other considerations in terms of the worker's comfortability while wearing the shoe.

An example of a safety measure known as FOPR is the angle of safety. This is the angle that is provided when a worker is standing in a working area. OSHA has defined this as a value in relation to OSHA Construction Directory Number 1. This is a system that helps workers know their safety needs and the significance behind them.

With the increase of technology, there have been changes in the construction industry. With the use of computers and other advanced technologies, the way materials are handled has changed dramatically. While these changes allowed materials to be handled without causing injury to workers, there have been cases when this was not done correctly. OSHA has been defined by these changes as meaning that any change in safety or health requirements must be communicated to all employees well in advance. There have also been many cases where workers have felt unsafe because they did not receive proper information about the new requirements.

In order to meet this new requirement of the safety code, FOPR has been implemented into OSHA's International Standard for Safety. If a worker wears safety shoes that do not meet this requirement, it can lead to an OSHA charge of discrimination. When a construction worker wears safety shoes that do not meet this requirement, there could be a violation of FOPR. There have also been suits brought forth by OSHA for the same case, stating discrimination.

For a company that makes construction equipment, it should not matter what safety shoes a worker wears. The company should be held responsible for the safety of all of its workers, regardless of whether they work for them or not. FOPR is a tool that every company should take full advantage of. It provides the information a company needs to make the workplace safe and comfortable for all of its employees.
