HHO Confined Space Entry Training

1. HAVERHILL OPERATIONS
Confined Space Entry Training
Rev. May 2019

2. • A confined space
– Is Large enough and so configured that an
employee can bodily enter and perform work;
– Has limited or restricted means of entry or exit;
– Isn’t designed for continuous occupancy
• A confined space requires a permit if it
– Contains or has the potential to contain a
hazardous atmosphere;
– Contains a material that has the potential for
engulfing an entrant;
– Has an internal configuration such that an
entrant could become trapped or asphyxiated
by inwardly converging walls or by a floor
which slopes downward and tapers to a
smaller cross-section; or
– Contains any other serious safety or health
hazard
General Requirements

3. • Oxygen Deficiency
– <19.5%
– >23.5% oxygen
Potential Hazards
• Airborne combustible
dust >/= 10% of its lower
flammable limit (LFL)
• Airborne concentration
of any substance > PEL

– Hydrogen Sulfide
– Welding fumes
– Corrosives
• Flammable gas, vapor,
or mist >10% of its
lower explosive limit
(LEL)
• Acetylene
• Propane
• Gasoline fumes
A Hazardous Atmosphere exists when there is a risk of death,
incapacitation, impairment of ability to self-rescue, injury, or acute
illness from one or more of the following causes:
OR when there is any other atmospheric
condition that is immediately dangerous
to life and health (IDLH)

4. • You’ve entered a confined space when any part of your body
passes through the opening into the confined space
• Confined Space personnel include
– Authorized Entrants
– Attendant/Hole Watch
• Required for each Confined Space Location
– May attend more than one space in a location if all duties can
be effectively performed
• Must be trained in emergency rescue (if responsible for rescue)

– Entry Authorizer
• SunCoke Personnel

Entry

5. • Must exchange air in
space as specified in table
• Must be positive pressure
and use a clean air source
– Negative pressure may
be allowed in some
instances

• Remove potential contaminants within 35-feet of space
• Ventilation must be used to remove any potential hazards &
whenever hot work is performed inside the space

6. • Before initial testing, turn off ventilation for 10 mins
• Test the atmosphere from outside of the space, using a 5-gas meter to
ensure
– LEL is 10% or less
– Oxygen > 19.5% and < 23%
– Carbon monoxide is 50 ppm or less
– SO2 is 5 ppm or less
– Hydrogen sulfide is 10 ppm or less
• Monitor alarm will sound at 5ppm
• Test additional parameters as necessary
• Ensure meters have been calibrated within 30 days
• Bump test meter each day before use

Ventilation Fan was not properly sized for space (initial atmospheric readings were within safe
ranges). Work was stopped. Entrants evacuated. Additional fan was added and additional
readings were taken and were within safe levels. Work resumed.
