Blue flag protection in the railroad industry provides safety to workers from the inadvertent movement of equipment on which they
;
are working. Current Federal regulations provide minimum specifications for the devices that can be used as blue flags, allowing
;
many devices to be used as long as they are blue. Safety standards developed by national and international committees that have
;
been adopted throughout a wide variety of high hazard industries, however, require greater specificity in the design of safety signs
;
and signals. An analysis of 11 commercially available blue safety flag products revealed that 5 did not meet any safety standards
;
beyond the minimum government regulations, and only 1 met the requirements of the most stringent safety code.
;
Recommendations are provided for blue safety flags that are consistent with the current meaning and use in the railroad industry
;
and that meet current safety code guidelines.
