The subject report is attached and discusses the results of the air
sampling survey that I conducted on
July 23rd at the ACME Printing Corporation facility in Happy Valley,
WS. The purpose of the survey
was to evaluate personal exposures to select components of commonly
used chemicals associated with
the ACME printing process. An additional sample was collected to
assess ambient concentrations of
ozone. A discussion of relevant exposure limits is included.

ACME Printing Corporation has had an active air-sampling program in
place for several years. Air
sampling was conducted to assess personal exposures to select
components of commonly used
chemicals associated with the printing process. An additional sample
was collected to assess ambient
concentrations of ozone. A total of five personal samples were collected
and analyzed for ink
components; one area sample was collected and analyzed for ozone.
Sampling was conducted in
accordance with established procedures with results being compared to
two relevant exposure limits.
Personal samples ranged from 14.8 - 59.0% of the calculated additive
Permissible Exposure Limit (i.e.,
n-propanol and n-propyl acetate combined). The results are in general
agreement with samples taken in
previous years. The area sample result for ozone was deemed
insignificant after it was determined that
the lamination process was non-operational the day of the study.
Recommendations are made to share
results with affected personnel, continue the annual sampling survey,
and conduct another ozone study. BACKGROUND
The printing industry uses a variety of inks, solvents, and adhesives that
have chemical constituents
deemed hazardous according to definitions established by the
Occupational Safety and Health
Administration (OSHA). Federal regulations require employers to
evaluate employee exposures to
select substances and assure that airborne concentrations do not exceed
eight-hour, time-weighted
averages known as Permissible Exposure Limits (PELs). Employee
exposures below PELs are not
expected to cause adverse health effects in a majority of a healthy
working population.
To evaluate exposures, ACME Printing has been conducting air
sampling on an annual basis for
several years. Previous year’s results have generally shown personal
sampling results at or below 50%
of the applicable PEL. Area samples in high traffic areas near production
units have shown levels
below PELs. Additional process-specific studies have also been
conducted and have shown localized
areas where ambient concentrations exceed the applicable PEL.
However, given the highly variable
nature of work activities, workers do not occupy these areas for enough
time to reach the PEL. Finally,
air-sampling surveys have been conducted that characterize short-
duration, potentially high-exposure
activities. These studies showed ambient vapor concentrations near the
associated OSHA short-term
exposure limit but concluded that the infrequent nature of the activity
and the “worst case” design used
for the study resulted in low worker exposure potential. CHEMICAL
HAZARDS & EXPOSURE POTENTIAL
A review of current chemical usage shows that inks and adhesives are
two of the most commonly used chemical
materials across the plant. A review of the Safety Data Sheets (SDSs) for
a typical ink and adhesive used shows
two primary ingredients: n-propyl alcohol (n-propanol) and n- propyl
acetate. A brief hazard review and
exposure assessment is as follows: Chemical Name CAS# Primary

Retrieved f http://www.cdc.gov/niosh/npg To evaluate exposure
potential, ACME Printing Corporation has been conducting air sampling
on an
annual basis for several years. Previous year’s results have generally
shown personal sampling results
at or below 50% of the applicable PEL. Several other exposure studies
have been conducted on a
process-specific basis and have also documented low worker exposure
potential. However, given the
variable nature of the business, ACME Printing Corporation has taken a
prudent approach of
documenting worker exposures on an annual basis. SAMPLING
STRATEGY
A sampling strategy was devised in consultation with the Plant Director.
In addition to the organic
constituents routinely included in past annual surveys, an area sample
was collected for ozone. Ozone
is a by-product of the lamination process and has been of interest to
plant personnel recently. The
following samples were collected for this year’s study:
Personal Sample – Josh, W&H 3 - n-propanol, n-propyl acetate
Personal Sample – Jake, W&H 2 - n-propanol, n-propyl acetate
Personal Sample – Percy, Vision - n-propanol, n-propyl acetate
Personal Sample – Mike, Pre-Press - n-propanol, n-propyl acetate
Personal Sample – Ronnie, W&H 3 – n-propanol, n-propyl acetate
Area Sample – Laminator Work Station - ozone SAMPLING
METHODOLOGY
A total of five personal air samples and one area sample were collected.
Air sampling was conducted
using a sampling pump and appropriate filter media provided by the
analytical lab contracted for the
project. Pumps were operated for as close to a full shift as possible with
a flow rate that ensured
collection of the necessary air volume stated in the analytical method
established by the National
Institute for Occupational Safety and Health (NIOSH). All pumps were
pre- and post-calibrated to
ensure accurate airflow rates. Personal samples were placed in the
breathing zone of the employee with
the sampling cassette being attached to the lapel; the area sample was
placed in a location where
employees are expected to spend most their time. Sampling media was
sent for analysis to a laboratory
accredited by the American Industrial Hygiene Association (AIHA).
SAMPLING RESULTS
Attachment A contains Tables 1-6 that summarize the sampling results.
All personal monitoring results
were compared to the applicable PEL. For n-propyl alcohol and n-propyl
acetate, an additive formula
method was used. Since both materials have similar potential adverse
health effects (e.g., both affect
the central nervous system), it is acceptable to consider exposure to each
in an additive fashion (see
data tables for specific calculations).
Table 1 shows personal air sampling results for Josh, W&H 2. This
sample showed an ambient
concentration of n-propanol of 47.0 parts per million (ppm) and 14.0
ppm of n-propyl acetate. The
additive percentage of the PEL is 30.5%. Table 2 shows personal air
sampling results for Jake, W&H 2. This sample showed an ambient
concentration of n-propanol of 64.0 parts per million (ppm) and 26.0
ppm of n-propyl acetate. The
additive percentage of the PEL is 40.0%.
Table 3 shows personal air sampling results for Percy, Vision. This
sample showed an ambient
concentration of n-propanol of 23.0 parts per million (ppm) and 6.5 ppm
of n-propyl acetate. The
additive percentage of the PEL is 14.8%.
Table 4 shows personal air sampling results for Mike, Pre-Press. This
sample showed an ambient
concentration of n-propanol of 32.0 parts per million (ppm) and 10.0
ppm of n-propyl acetate. The
additive percentage of the PEL is 21.0%.
Table 5 shows personal air sampling results for Ronnie, W&H 3.
This sample showed an ambient
concentration of n-propanol of 91.0 parts per million (ppm) and 27.0
ppm of n-propyl acetate. The
additive percentage of the PEL is 59.0%.
Table 6 shows area sampling for the sample taken at the laminator work
station. This sample showed
an ambient concentration of ozone of <0.013 ppm which is 2.5% of
the PEL. DISCUSSION & RECOMMENDATIONS
All personal samples are below their respective PELs and in general
agreement with the range of
personal exposures measured in previous years. Although ACME
Printing continues to be in
compliance with OSHA regulations, it is a best management practice to
keep employee exposures
below 50% of the relevant PEL. Accordingly, ACME Printing should
continue to conduct annual
sampling and periodically assess any trends associated with exposures
(i.e., are exposures regularly
exceeding 50% of the PEL). Recommendations are as follows:
1) Share sampling information with employees. ACME Printing has a
strong record of sharing
monitoring results with affected employees. Employees are well versed
in the meaning of
sampling and employee exposure results.
2) Continue the annual air-sampling program. Day to day operations can
change and may impact
exposure potential to employees. It is prudent to conduct regular air
sampling even though ACME
Printing is full compliance with OSHA regulations.
3) Conduct a separate study to evaluate ozone concentrations. It is
unfortunate that the
lamination unit did not end up running on the day of sampling. A
separate study should be
conducted to fully evaluate ambient ozone concentrations.

Osh 4301 provide an overview of the results/tutorialoutlet

  • 1. OSH 4301 Provide an overview of the results FOR MORE CLASSES VISIT tutorialoutletdotcom The subject report is attached and discusses the results of the air sampling survey that I conducted on July 23rd at the ACME Printing Corporation facility in Happy Valley, WS. The purpose of the survey was to evaluate personal exposures to select components of commonly used chemicals associated with the ACME printing process. An additional sample was collected to assess ambient concentrations of ozone. A discussion of relevant exposure limits is included. If you have any comments or questions, call me at 720/123-4567. Thank you. Signature Here Sam “IH” Sampler Industrial Hygienist 1234 1st Street Gilbert, WS 70002 720/123-4567 2012 ANNUAL AIR SAMPLING REPORT ACME Printing Corporation, Inc. September 4, 2014 Sampling Conducted By: Sam “IH” Sampler Industrial Hygienist 1234 1st Street Gilbert, WS 70002 720/123-4567 EXECUTIVE SUMMARY ACME Printing Corporation has had an active air-sampling program in place for several years. Air sampling was conducted to assess personal exposures to select
  • 2. components of commonly used chemicals associated with the printing process. An additional sample was collected to assess ambient concentrations of ozone. A total of five personal samples were collected and analyzed for ink components; one area sample was collected and analyzed for ozone. Sampling was conducted in accordance with established procedures with results being compared to two relevant exposure limits. Personal samples ranged from 14.8 - 59.0% of the calculated additive Permissible Exposure Limit (i.e., n-propanol and n-propyl acetate combined). The results are in general agreement with samples taken in previous years. The area sample result for ozone was deemed insignificant after it was determined that the lamination process was non-operational the day of the study. Recommendations are made to share results with affected personnel, continue the annual sampling survey, and conduct another ozone study. BACKGROUND The printing industry uses a variety of inks, solvents, and adhesives that have chemical constituents deemed hazardous according to definitions established by the Occupational Safety and Health Administration (OSHA). Federal regulations require employers to evaluate employee exposures to select substances and assure that airborne concentrations do not exceed eight-hour, time-weighted averages known as Permissible Exposure Limits (PELs). Employee exposures below PELs are not expected to cause adverse health effects in a majority of a healthy working population. To evaluate exposures, ACME Printing has been conducting air sampling on an annual basis for several years. Previous year’s results have generally shown personal sampling results at or below 50%
  • 3. of the applicable PEL. Area samples in high traffic areas near production units have shown levels below PELs. Additional process-specific studies have also been conducted and have shown localized areas where ambient concentrations exceed the applicable PEL. However, given the highly variable nature of work activities, workers do not occupy these areas for enough time to reach the PEL. Finally, air-sampling surveys have been conducted that characterize short- duration, potentially high-exposure activities. These studies showed ambient vapor concentrations near the associated OSHA short-term exposure limit but concluded that the infrequent nature of the activity and the “worst case” design used for the study resulted in low worker exposure potential. CHEMICAL HAZARDS & EXPOSURE POTENTIAL A review of current chemical usage shows that inks and adhesives are two of the most commonly used chemical materials across the plant. A review of the Safety Data Sheets (SDSs) for a typical ink and adhesive used shows two primary ingredients: n-propyl alcohol (n-propanol) and n- propyl acetate. A brief hazard review and exposure assessment is as follows: Chemical Name CAS# Primary Route(s) of Exposure Health Hazard n-propyl alcohol 71-23-8 inhalation, dermal absorption irritation eyes, nose, throat; dry cracking skin; drowsiness, headache; ataxia, gastrointestinal pain; abdominal cramps, nausea, vomiting, diarrhea n-propyl acetate 109-60-4 inhalation, dermal absorption irritation eyes, nose, throat; narcosis; dermatitis Exposure

Retrieved f http://www.cdc.gov/niosh/npg To evaluate exposure potential, ACME Printing Corporation has been conducting air sampling on an annual basis for several years. Previous year’s results have generally shown personal sampling results at or below 50% of the applicable PEL. Several other exposure studies have been conducted on a process-specific basis and have also documented low worker exposure potential. However, given the variable nature of the business, ACME Printing Corporation has taken a prudent approach of documenting worker exposures on an annual basis. SAMPLING STRATEGY A sampling strategy was devised in consultation with the Plant Director. In addition to the organic constituents routinely included in past annual surveys, an area sample was collected for ozone. Ozone
  • 5. is a by-product of the lamination process and has been of interest to plant personnel recently. The following samples were collected for this year’s study: Personal Sample – Josh, W&H 3 - n-propanol, n-propyl acetate Personal Sample – Jake, W&H 2 - n-propanol, n-propyl acetate Personal Sample – Percy, Vision - n-propanol, n-propyl acetate Personal Sample – Mike, Pre-Press - n-propanol, n-propyl acetate Personal Sample – Ronnie, W&H 3 – n-propanol, n-propyl acetate Area Sample – Laminator Work Station - ozone SAMPLING METHODOLOGY A total of five personal air samples and one area sample were collected. Air sampling was conducted using a sampling pump and appropriate filter media provided by the analytical lab contracted for the project. Pumps were operated for as close to a full shift as possible with a flow rate that ensured collection of the necessary air volume stated in the analytical method established by the National Institute for Occupational Safety and Health (NIOSH). All pumps were pre- and post-calibrated to ensure accurate airflow rates. Personal samples were placed in the breathing zone of the employee with the sampling cassette being attached to the lapel; the area sample was placed in a location where employees are expected to spend most their time. Sampling media was sent for analysis to a laboratory accredited by the American Industrial Hygiene Association (AIHA). SAMPLING RESULTS Attachment A contains Tables 1-6 that summarize the sampling results. All personal monitoring results were compared to the applicable PEL. For n-propyl alcohol and n-propyl acetate, an additive formula method was used. Since both materials have similar potential adverse health effects (e.g., both affect the central nervous system), it is acceptable to consider exposure to each
  • 6. in an additive fashion (see data tables for specific calculations). Table 1 shows personal air sampling results for Josh, W&H 2. This sample showed an ambient concentration of n-propanol of 47.0 parts per million (ppm) and 14.0 ppm of n-propyl acetate. The additive percentage of the PEL is 30.5%. Table 2 shows personal air sampling results for Jake, W&H 2. This sample showed an ambient concentration of n-propanol of 64.0 parts per million (ppm) and 26.0 ppm of n-propyl acetate. The additive percentage of the PEL is 40.0%. Table 3 shows personal air sampling results for Percy, Vision. This sample showed an ambient concentration of n-propanol of 23.0 parts per million (ppm) and 6.5 ppm of n-propyl acetate. The additive percentage of the PEL is 14.8%. Table 4 shows personal air sampling results for Mike, Pre-Press. This sample showed an ambient concentration of n-propanol of 32.0 parts per million (ppm) and 10.0 ppm of n-propyl acetate. The additive percentage of the PEL is 21.0%. Table 5 shows personal air sampling results for Ronnie, W&H 3. This sample showed an ambient concentration of n-propanol of 91.0 parts per million (ppm) and 27.0 ppm of n-propyl acetate. The additive percentage of the PEL is 59.0%. Table 6 shows area sampling for the sample taken at the laminator work station. This sample showed an ambient concentration of ozone of <0.013 ppm which is 2.5% of the PEL. DISCUSSION & RECOMMENDATIONS All personal samples are below their respective PELs and in general agreement with the range of personal exposures measured in previous years. Although ACME Printing continues to be in compliance with OSHA regulations, it is a best management practice to
  • 7. keep employee exposures below 50% of the relevant PEL. Accordingly, ACME Printing should continue to conduct annual sampling and periodically assess any trends associated with exposures (i.e., are exposures regularly exceeding 50% of the PEL). Recommendations are as follows: 1) Share sampling information with employees. ACME Printing has a strong record of sharing monitoring results with affected employees. Employees are well versed in the meaning of sampling and employee exposure results. 2) Continue the annual air-sampling program. Day to day operations can change and may impact exposure potential to employees. It is prudent to conduct regular air sampling even though ACME Printing is full compliance with OSHA regulations. 3) Conduct a separate study to evaluate ozone concentrations. It is unfortunate that the lamination unit did not end up running on the day of sampling. A separate study should be conducted to fully evaluate ambient ozone concentrations.
