Barricade Dangerous Areas
|Mine Type: Surface and Underground Coal and M/NM|

The victim was obviously unaware of the amount of dust accumulation that could occur in the certain areas of duct. Further, the victim felt it safe to explore the duct since the operation was down and tagged out.
The regulation requires the posting of signs or the construction of barricades to warn people of health and safety hazards which are not readily obvious. Barricades are much better than signs which sometimes have an opposite effect. Signs tend to invite exploration whereas barricades prevent it.
So, if you have outside contractors or even your own people working in places where hazards exist but are not apparent, don't only post a sign, barricade the area off. It may seem like overkill but in these cases it is better to "GO THE EXTRA MILE".
