Industrial Hygiene &
Respiratory Care
John Newquist
Draft 1 5 2015
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."
Exposure Limits
• Animal Studies
• Epidemiological
studies
• Industrial Experience
• STEL – 15 minutes
• Ceiling – never
exceeded
• Threshold Limit Value
Sampling
• Qualified person
• Appropriate
instrument
• Duration of sampling
• Pre and post
calibration
Hierarchy of Controls
• Engineering
• Administrative
• Personal Protective
Equipment
• Training
Problem #1 Noise
• BLS
• 125,000+ workers w permanent, hearing
loss since 2004
• In 2008 alone, 22,000 hearing loss cases
were reported
#1 Noise
• Hearing Protection worn
20%*
• Several processes
involving hammering,
cutting, blasting will cause
overexposure
• Set up an effective hearing
conservation program
REMEMBER!
• The aforementioned
applies to
overexposures above
90 dBA TWA
(Time-Weighted-
Average)
“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
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)
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
Hearing
Protection
• Ear plugs
• Ear muffs
• Audiometric testing
• More information provided in
training on hearing
conservation
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

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
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
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
#2 Lead
• Requires compliance with 1910.1025
• Overexposure can occur in less than 5 minutes
when torch cutting or painting
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
#3 Silica
• Cutting, hammering,
drilling, blasting can
create high silica
levels
• Use wet methods and
wear respirators
• One of the oldest
occupational diseases
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.
#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?
#5 Total Dust
• All the things not
regulated.
• Good, bad, or
indifferent?
• Air blowing!
#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
#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
#8 Hex Chrome
• Stainless steel contains
nickel and chromium
• Plating, grinding,
welding are problems
• Some cements
# 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.
#10 Methylene Chloride
• Paint stripping
• Parts cleaners
• Cancer causing
Asbestos
• Common Fireproofing
material used pre-
1980s
• Found in pipe
insulation, ceiling
tiles, and floor tiles
• Must comply with
1926.1101 or
1910.1001
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.
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
SUNBURN
Dealing with Heat Stress
Heat stress can be more than a minor inconvenience for those who work in
extremely warm conditions. Knowing how to prevent, identify and treat its
symptoms can literally save lives.
Symptoms
• Red, painful skin (first degree burns)
• Blistering and/or peeling (second degree burns)
Treatment
• Skin lotions
• Topical anesthetics
Prevention
• Limit sun exposure on bare skin
HEAT RASH & CRAMPS
Symptoms
• Red rash and itching
• Hot, moist skin
• Normal to slightly high body temperature
Treatment
• Ointment
Prevention
• Keep skin dry and clean
• Loosen clothing
• Drink lightly salted liquids (.1% saline)
• Seek medical aid if cramps persist
Dealing with Heat Stress
HEAT EXHAUSTION
First Aid Treatment
• Loosen or remove clothing and boots
• Cool the victim as fast as possible
• Call 911 if victim becomes faint or is unconscious
Symptoms
• Heavy sweating
• Intense thirst from dehydration
• Fatigue, weakness or loss of coordination
• Tingling in hands and feet or headache
Dealing with Heat Stress
HEAT STROKE
Early Symptoms
• High body temperature
• Hot, red or flushed, dry skin
• Headache or dizziness
• Confusion or delirium
Advanced Symptoms
• Seizure or convulsions
• Loss of consciousness
• No detectable pulse
Call 911 at the first sign of the above symptoms!
Dealing with Heat Stress
HEAT STROKE
Treatment
• Lower the victim’s body temperature as fast as possible
• Don’t give liquids to unconscious victims
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
Dehydration
Confined Spaces
• Manholes, pits, vaults,
tanks, are common
confined spaces
• Ensure atmosphere is
safe by testing and
ventilating
Worker in a sludge pit exposed
to lead, arsenic, and cadmium
Paint Solvents
• Ventilation is required
or overexposure can
result
• Fire Hazard
• Electrical must be
Class I if within 20
feet during open
spraying with
flammable paints
Tank painting. What could go
wrong?
Waterproofing
• Volatile compounds
are heavier than air
and toxic.
• Death
• Hazards similar to a
confined space
Diesel Fuel Exhaust
• blue smoke (mainly oil and
unburnt fuel)
• black smoke (soot, oil and
unburnt fuel);
• white smoke (water droplets
and unburnt fuel)
• Diesel Fuel Exhaust is
reasonably anticipated to be
a human carcinogen per
IARC

2015 industrial hygiene & respiratory care

  • 1. Industrial Hygiene & Respiratory Care John Newquist Draft 1 5 2015
  • 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."
  • 3. Exposure Limits • Animal Studies • Epidemiological studies • Industrial Experience • STEL – 15 minutes • Ceiling – never exceeded • Threshold Limit Value
  • 4. Sampling • Qualified person • Appropriate instrument • Duration of sampling • Pre and post calibration
  • 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
  • 8. REMEMBER! • The aforementioned applies to overexposures above 90 dBA TWA (Time-Weighted- Average)
  • 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
  • 14. Noise levels versus Duration Sound Level (dBA) 90 92 95 100 105 110 115 Exposure (hours) 8 6 4 2 1 0.5 0.25
  • 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.
  • 28. #10 Methylene Chloride • Paint stripping • Parts cleaners • Cancer causing
  • 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
  • 32. SUNBURN Dealing with Heat Stress Heat stress can be more than a minor inconvenience for those who work in extremely warm conditions. Knowing how to prevent, identify and treat its symptoms can literally save lives. Symptoms • Red, painful skin (first degree burns) • Blistering and/or peeling (second degree burns) Treatment • Skin lotions • Topical anesthetics Prevention • Limit sun exposure on bare skin
  • 33. HEAT RASH & CRAMPS Symptoms • Red rash and itching • Hot, moist skin • Normal to slightly high body temperature Treatment • Ointment Prevention • Keep skin dry and clean • Loosen clothing • Drink lightly salted liquids (.1% saline) • Seek medical aid if cramps persist Dealing with Heat Stress
  • 34. HEAT EXHAUSTION First Aid Treatment • Loosen or remove clothing and boots • Cool the victim as fast as possible • Call 911 if victim becomes faint or is unconscious Symptoms • Heavy sweating • Intense thirst from dehydration • Fatigue, weakness or loss of coordination • Tingling in hands and feet or headache Dealing with Heat Stress
  • 35. HEAT STROKE Early Symptoms • High body temperature • Hot, red or flushed, dry skin • Headache or dizziness • Confusion or delirium Advanced Symptoms • Seizure or convulsions • Loss of consciousness • No detectable pulse Call 911 at the first sign of the above symptoms! Dealing with Heat Stress
  • 36. HEAT STROKE Treatment • Lower the victim’s body temperature as fast as possible • Don’t give liquids to unconscious victims 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 • Ensure atmosphere is safe by testing and ventilating Worker in a sludge pit exposed to lead, arsenic, and cadmium
  • 39. Paint Solvents • Ventilation is required or overexposure can result • Fire Hazard • Electrical must be Class I if within 20 feet during open spraying with flammable paints Tank painting. What could go wrong?
  • 40. Waterproofing • Volatile compounds are heavier than air and toxic. • Death • Hazards similar to a confined space
  • 41. Diesel Fuel Exhaust • blue smoke (mainly oil and unburnt fuel) • black smoke (soot, oil and unburnt fuel); • white smoke (water droplets and unburnt fuel) • Diesel Fuel Exhaust is reasonably anticipated to be a human carcinogen per IARC What else is toxic in this ????
  • 42. Mold • Stachybotrys chartarum (also known as Stachybotrys atra) • Aspergillus sp. • Penicillium sp. • Fusarium sp. • Trichoderma sp. • Memnoniella sp. • Cladosporum sp. • Alternaria sp.
  • 43. First Aid First aid training Good Samaritan Collateral duty* Designated responder Not covered by BBP Standard BBP standard applies * if First-Aid response is an expected part of the job BBP standard applies
  • 44. Universal Precautions Treat as if known to be infectious All human blood Certain human body fluids All human body fluids if they can’t be distinguished
  • 45. Regulated Waste Handling • When moving containers: » Close immediately » If leaking, place in secondary container » If reusable, clean in a manner that will not expose employees.
