Physical guards

Wilkinson and coworkers also tested a membraneless direct methanol fuel cell, built by replacing the PEM by an open spacer filled with liquid electrolyte (aqueous H2SO4). Reasonable power densities (close to 10 mW.cm ) were reached, and the main aim of the new architecture, to control the total power output of the cell, was achieved by disrupting the TPR with a physical guard on or within the electrode assembly [42]. 

Physical Guarding Measures to prevent the physical contact with the moving parts of machines such as covering of the machine or safeguarding measures.

If controlling the hazards through improved design or engineering is impossible or impractical, the next course of action should be to use physical guards or barriers to separate potential unwanted energy flows or other hazards from potential targets. 

Design and engineering controls and physical guards and barriers may provide positive protection and actually eliminate the occurrence of certain types of accidents. 

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. 

Physical guarding of sprockets, pulley belts, and other exposures...
