Section 5(a)(1) of the Occupational Safety and Health Act of 1970:  The
employer did not
furnish employmnent and a place of employment which were free from
recognized hazards that
were causing or likely to cause death or serious physical harm to
employees in that employees
were exposed to:
(a)During the heat treat processes, an employee places steel onto a slow
moving
conveyor belt from one end, which goes into the oven and heated to 1750
degrees
for 8-10 minutes. The actual WBGT at this location is 94.60 F, the TLV is
88.0
F.  The hot steel is then taken off the conveyor belt by an employee at
the other
end of the conveyor using a hydraulic clamp, which is then placed onto a
molding
machine, and then automatically dipped into an oil bath and eventually
cooled.
The employee taking the steel off the conveyor stands approximately
2.5-3.5 feet
from the oven which radiates a large amount of heat.  Above the employee
is a
laminar air flow duct that brings in a large amount of ambient air from the
outside (roof) and is used to cool him.  However, the WBGT temperature
under
the duct was only slightly cooler than the  surrounding hot environment.
The
actual WBGT in this area is 100.0 F, the TLV is 85.0 F.  The cycle repeats
itself
every 2 minutes resulting in approximately 350 springs/day or 175 springs
per
person. The two employees volunteer to rotate from one end of the conveyor
to
the other every 30 minutes to one hour depending on how hot the day.
(b)The Hille forging operation, a steel spring comes off the conveyor belt
out of the
hot (1800 degree) oven, which is then taken by the employee to the taper
machine
and 3 holes are punched into the hot steel. The employee stack the steel
onto a
metal cart to cool.  He then rests or stands at the conveyor until the
next spring
comes down.  The employee has 3 fans blowing in the area. The actual WBGT
in this area is 90.11 F, the TLV is 80.0 F. The cycle repeats itself
approximately
every 1.5 minute.  Two employees again voluntarily rotate every 15-25
minutes
depending on how hot the day.
(c)Hot/cold punch area, the employee places steel onto the conveyor belt
which then
goes into the furnace.  At the end of the conveyor system the same employee
takes the hot steel off and places it under a punch press to punch holes
into the
steel and is then placed on a holding cart to cool. The employee stands
under a
laminar air flow duct which brings in ambient air from the outside. The
employee
does not rotate and he punches 4-500 pieces of steel per day. The actual
WBGT
for this employee is 96.29 F, the TLV is 89.0 F.
(d)The batch treat department, an employee puts steel springs into the
furnace, allow
it to heat for 15 minutes, take them out and place the steel on a manual
molding
machine.  He takes the steel off the machine and manually dips it into an
oil bath.
After the steel cools (15 minutes) it is then placed on a dripping rack.
The
employee pulls about 16 heats a day or 2-3 heats per hour.  While the
steel is
heating the employee takes a break into the air conditioned break room or
outside. The actual WBGT reading for this employee is 98.9 F, the TLV is
90.0
F.
