Hydrogen sulfide blocks oxygen from binding with blood cells
August 2013• Robert Honomichl, 55, and
Minden NE Utilities Superintendent Mike Kleen, 51, were clearing a blockage in a sewer line when they were overcome by the toxic gases in the manhole where they were working Sunday afternoon.
• Honomichl passed away August 13, 2013
July 2013
• Tampa FL• A 24-year-old man died
and his father is in critical condition after losing consciousness and being pulled from inside an empty asphalt tanker truck Saturday, authorities said.
2013 NC• Autopsy: Catawba plant worker
died of hydrogen sulfide intoxicationSamir Storey, 39 and others were cleaning a 10-by-40-foot tank
• “clear, cloudy smoke” entered the tank, triggering emergency alarms, which trapped Samir in the tank.
• Hydrogen sulfide affects the body in two ways, she said. It blocks oxygen from binding with blood cells, and it interrupts the central nervous system, which, in turn, affects the respiratory system.
May 2013• WAUCEDAH TOWNSHIP, Mich• Worker climbed into the 12-foot-
deep well in Dickinson County's Waucedah Township on Wednesday afternoon to make repairs.
• State police say a friend lowered dry ice into the well that was to be used in the repair, but the dry ice reacted and used up oxygen at the bottom of the well.
• Police say the man lost consciousness while trying to climb out and the friend called 911. Rescue crews got the man out, but he died.

Confined Space Most Cited
• Not evaluating confined spaces
• No Confined Space signs
• No written Confined Space Program
• No Permit before Entry• Employee Training
• No Rescue Provisions• Not testing the
Confined Space• Not developing safe
permit entry operations• Entry Supervisor not
verifying tests were conducted
• No retrieval system where practical
Examples
• Manholes • Grain Bins• Tanks• Vaults
History
• No standard for years - proposed 1976
• Film Recovery – Hydrogen cyanide -1983

in 1993
Statistics
• Over 224,000 worksites have permit spaces• Over 2.1 million workers enter permit spaces
annually• Compliance with 1910.146 will save:
- at least 53 worker deaths- 4,900 lost workday cases- 5,700 non lost-time accidents ANNUALLY
Idaho 2000
• Allan Elias, 61, was ordered to serve 17 years in Jail
• $6.3M in restitution• Told workers to clean
cyanide tank without respirators
• Employee suffered permanent brain damage
Confined Space
A space that: Is large enough and so
configured that an employee can bodily enter and perform assigned work
Has limited or restricted entry/exit means
Is not designed for continuous Employee occupancy
Permit Space
• a risk of death, incapacitation, injury or acute illness
• flammable gases• oxygen deficient • toxic atmosphere• engulfment, • other serious physical
hazards
Permits
• The following permit has been designed to assist in protecting persons entering confined spaces. It shall be completed before any employee enters a space designated as a "Permit-Required Confined Space". Only individuals that have received Confined Space Training shall be authorized to complete this permit. All questions that are not applicable to the entry are to be answered as "N/A". This section is to be completed by the confined space entry supervisor.

Provide advisory training prior to entry of any space
Manufacturing
• 1995 - IL• Open pit 45’ x’ 60’• Argon gas had been
used instead of compressed air to operate a pump that removed water from the pit.
• 3 died
Typical Machine Pit
Argon
• Several multiple fatalities where argon is used.
• Inert, colorless, odorless.
• Much more heavier than air.

Rescue
• Sixty percent (60%) of all confined space deaths were the would-be-rescuers
• Rescue equipment must be maintained
• Run practice drills
