Barrier guard

Screens, bars, or other mechanical harriers affixed to the frame of a machine, intended to prevent entry by personnel into the hazardous area(s) of a machine, while allowing the point of operation to he viewed. The maximum size of openings is determined by Table 0-10 of Occupational Safety and Health Administration (OSH A) standard 1910.217. It may also he called a fixed barrier guard. 

A form of guard that has a movable part connected with the machinery so that the parts of the machine causing a hazard cannot be set in motion until the guard is in place. Before the guard can be opened sufficiently to allow access to the work area, the power is turned off and the motion is braked to prevent potential injuries to workers. It may also be called Interlocked Barrier Guard. See also Barrier Guard Interlock Machine Guarding.

This chapter will focus on those warehouse hazards that need physical guarding or identification in some way. The proper design and construction of many physical safeguards requires that they be not only secure and substantial, but that they also meet OSHA guidelines. Something as basic as a physical pinch point exposure that requires a barrier guard should be of concern to each employee. Employees that work and travel through various parts of the warehouse could easily be exposed to many additional physical risks.
