SCRR 71-112A: Failed to furnish a place of employment which is free of
recognized hazards
which may cause death or serious physical harm to his employees and comply
with this
regulation and other occupational safety and health rules and regulations
promulgated under
Chapter 15 of Title 41, Code of Laws, State of South Carolina, 1976, as
amended, as
follows:
A.  Employer knew or should have known that employees entering a manhole
were exposed
to hazards associated with entry into a confined space and of being burned
by steam, such as
the manhole entered at George Street at Porter's Lodge on or about October
8, 2001.  A
feasible and useful means of abatement, among others, is development and
enforcement of a
written confined space entry program which includes as a minimum the
following elements:
1)  Testing the confined space atmosphere for oxygen level, flammability,
and known or
suspected toxic substances prior to entry;
2)  Establish and enforce work procedures, including safety lines and a
standby
person when
needed, and respiratory equipment as appropriate;
3)  Establish pre-planned rescue procedures;
4)  Establish written lock-out procedures to ensure that, prior to
employees performing
service or maintenance on steam lines, the steam lines be isolated from
the energy source to
prevent unexpected release of steam.
