2. August 2013
• Franklin, NC
• One person has died and 16 others
were hospitalized from exposure to
high levels of carbon monoxide in
a packing facility
• "We monitored the (carbon
monoxide) levels once we got
there, and the highest reading we
got was 1,000 parts per million."
5. Hierarchy of Controls
• Engineering
• Administrative
• Personal Protective
Equipment
• Training
6. Problem #1 Noise
• BLS
• 125,000+ workers w permanent, hearing
loss since 2004
• In 2008 alone, 22,000 hearing loss cases
were reported
7. #1 Noise
• Hearing Protection worn
20%*
• Several processes
involving hammering,
cutting, blasting will cause
overexposure
• Set up an effective hearing
conservation program
9. “Effective hearing conservation
program?”
Monitoring
Engineering, work practice,
and administrative controls
Hearing protectors with an
adequate noise reduction
rating
Employee training and
education in hazards and
protection measures
Baselines and annual
audiometry
10. Audiograms
• Conduct a baseline analysis on
all equipment (New too!)
• Employees can request personal
noise monitoring at any time at
VPP sites
• 60 employees were tested in IL.
• It cost $29.00 per person plus
some labor cost (VPP)
• Insurance carrier will charge
$35.00 per person. (VPP site)
11. Ear protection
Re-usable ear plugs:
• regular and careful washing
• fitted by a trained person
• must be good fit
• dust may irritate
• Ear defenders:
• well designed
• well made
• must be good fit
12. Hearing
Protection
• Ear plugs
• Ear muffs
• Audiometric testing
• More information provided in
training on hearing
conservation
13. Hearing Protection Basics
• Noise induced hearing loss can occur with
exposures >90 dBA
• A hearing conservation program becomes a
requirement at exposures >85dBA
• Higher levels of noise exposure have
shorter allowable exposure times
15. Hearing Protection
• Rule of Thumb - if you cannot carry on a
conversation in a normal tone of voice with
someone at arm’s length, you are likely near
90dBA
• All hearing protection devices should have
a Noise Reduction Rating (NRR) = # of
decibels they will reduce noise levels
• Be conservative when using NRRs
16. A couple examples
• Example 1
– Ear plugs with NRR of 25 dBA
– exposure = 105 dBA
– 105 minus 25 = 80 dB therefore okay
• Example 2
– same plugs
– exposure = 125 dBA
– 125 minus 25 = 100 dB not acceptable; must be
below 90 dB
17. Hearing Protection - Types
• Ear Plugs - less expensive, disposable, good
ones have fairly high NRRs - sometimes
difficult to tell if employees are wearing
them
• Ear Muffs - more expensive, more durable,
typically higher NRRs than plugs, more
obvious
• Can be used together in very high noise
areas
18. #2 Lead
• Requires compliance with 1910.1025
• Overexposure can occur in less than 5 minutes
when torch cutting or painting
19. Lead effects
• Chronic overexposure - severe damage to
the blood-forming, nervous, urinary, and
reproductive systems
• High levels will require medical removal
• Bridge Painting/Removal continues to be
ones of the consistent lead issues in
construction
20. #3 Silica
• Cutting, hammering,
drilling, blasting can
create high silica
levels
• Use wet methods and
wear respirators
• One of the oldest
occupational diseases
21. Silica
• 150-200 deaths a year
(2009)
• 1150-1200 deaths a
year (1968)
• Yet….one company
had 3 silicosis and
10x+ severe
respiratory diseases
Gauley Bridge in 1920’s had
workers die in months.
22. #4 Copper Fumes - Welding
• Copper is inhalation
hazard affecting
respiratory system
• Mild steel (red iron)
and carbon steel
contain manganese
• Manganese may
cause Parkinson's
disease
What do you see?
23. #5 Total Dust
• All the things not
regulated.
• Good, bad, or
indifferent?
• Air blowing!
24. #6 Iron Oxide -Welding
• Metal fume fever
• Direct Draw or forced
ventilation should be
used
• Personal Protective
Equipment should be
used
• Bystanders should be
protected as well
25. #7 Carbon Monoxide
• Generators are most
common problem of
CO
• Heaters out of tune are
another cause
• CO TWA is 50 ppm
• Others set levels 25
ppm
26. #8 Hex Chrome
• Stainless steel contains
nickel and chromium
• Plating, grinding,
welding are problems
• Some cements
27. # 9 Cadmium
• Overexposure to
cutting cadmium bolts,
coated poles
• Torch cutting should
never be used
• Use hydraulic bolt
cutters
• Comply with
1926.1127 Cadmium bolts are often
found in sprinkler pipe use.
29. Asbestos
• Common Fireproofing
material used pre-
1980s
• Found in pipe
insulation, ceiling
tiles, and floor tiles
• Must comply with
1926.1101 or
1910.1001
30. June 2014
• The asbestos lawsuit that
saw a $1 million award
• Richard Rost has
Mesothelioma
• Defendants included Ford
Motor Company (Ford),
General Electric,
Westinghouse and Ingersoll-
Rand.
• However, the latter three
defendants settled with the
plaintiffs out of court, before
the trial had an opportunity
to begin.
Overall, nearly 3,000 people
are diagnosed with mesothelioma each
year in the United States, which represents
0.02 percent of all U.S. cancer cases.
31. Heat Stress
• Train the workforce
• Perform the heaviest work in the
coolest part of the day
• Slowly build up tolerance to the
heat and the work activity
(usually takes up to two weeks)
• Drink plenty of cool water (one
cup every 15-20 minutes)
• Wear light, loose-fitting,
breathable (cotton) clothing
• Take frequent short breaks in
cool or shaded areas
• Provide fans

Other tips for controlling heat stress
• Allow your body to become acclimatized to
your surroundings
• Follow scheduled work/rest cycles to avoid
overexertion
• Drink 5-7 ounces of cool water every 15 minutes
• Consume a light, cool lunch instead of hot,
heavy meals
Dealing with Heat Stress
38. Confined Spaces
• Manholes, pits, vaults,
tanks, are common
confined spaces

to lead, arsenic, and cadmium
39. Paint Solvents
• Ventilation is required
or overexposure can
result
