Continuing Education Presents Certification Review Courses
Professional certification courses currently presented include: Comprehensive Industrial Hygiene (CIH), Certified Safety Professional (CSP), Certified Hazardous Materials Manager (CHMM), Certified Occupational Health Nurse (COHN) and Specialist (COHN-S), and Certified Occupational Health Nurse/Safety Management (COHN/SM). The Lab Safety course is a review for the Chemical Safety Officer (CSO). Please see the Continuing Education website at: http://osherc.sph.unc.edu/cert_review.htm
Ethics course is a NEW requirement for new and
recertified Industrial Hygienists
Beginning in 2010, new applicants and CIHs/CAIHs due to
recertify will be required to document that they have completed at
least two (2) hours of ethics training. For certification maintenance,
the ethics training is part of the requirement to show a minimum of 10
CM points per cycle in IH rubrics (during the 5 year cycle). For
certification applicants, the ethics training will be part of the
current IH coursework requirement. This new ethics requirement does NOT
affect those CIHs recertifying for the 2005-09 CM cycle.
In response to this certification requirement, The NC OSHERC
Continuing Education Program has added an extra hour into the CIH
Review Course directed by Dr. Nelson Couch and presented by Bob
Uhorchuck. The expanded course segment has received approval to
count toward the ABIH points in maintaining CIH certification. NC
OSHERC has also received approval from ABIH to offer this as a
stand-alone, two-hour Ethics course for CM points. Plans for
implementing an online course are being developed.
The newly revised ABIH Code of Ethics, and the ACGIH/AIHA Member Ethical Principles, clearly state that industrial hygienists shall "properly use professional credentials, and provide truthful and accurate representations concerning education, experience, competency and the performance of services." See ABIH Code of Ethics, Section II.A.5. Therefore, the misrepresentation of a certificant’s, applicant’s or examinee’s education and training, including CM courses, may violate these important ethics rules. Thus, the Ethics Review Committee cautions that if a full course is not attended and completed, it should not be listed on a resume or otherwise represented to ABIH, professional associations, government agencies, clients, employers, employees, or the public. See the website at: http://www.abih.org/documents/EthicsRequirements-Webversion.pdf

OSHA Recordkeeping Interpretations sought by CE Program Faculty
OSHA Injury and Illness Recordkeeping: Recent Interpretations
By Bill Taylor, CSP
www.ctjsafety.com
Maintaining the OSHA 300 injury and illness log is not an easy task. For this reason the consultants at CTJ Safety Associates get frequent questions from customers who are in need of guidance; therefore, we spend a great deal of time in contact with OSHA on behalf of those who come to us for assistance. When CTJ consultants request interpretations we go straight to those who write the rules at Federal OSHA. This helps to assure consistency in responses. Answers from regional offices may be different from those at Federal offices.
Recently there has been a change in personnel at the office which provides interpretations. For this reason we felt it necessary to have OSHA review some of the earlier interpretations we had gotten just to assure there had been no changes in philosophy. In very few cases has there been a change in information provided and we continue to get reliable and consistent interpretations from Federal OSHA.
Many of the interpretations that follow are not widely distributed or well known. Following are a few of the interpretations we have received since the beginning of the year and added to or updated on the CTJ Keyword Index.
Changing Flat Tire
Situation: An employee leaving work after his shift has ended
must change a flat tire on his personal vehicle in the company parking
lot. In the process he sustains an injury. Is the injury work related?
Interpretation: We brought this same question to Federal OSHA in January, 2002. The response was that changing a tire while in the company parking lot, even on a personal vehicle, is considered to be a work related activity. This, of course, makes the case work related. During a phone conversation on January 15, 2009, Federal OSHA confirmed the original interpretation, re-affirming the example given is still work related. And because recording criteria had been met the case would be recordable. The case would not be exempt as a motor vehicle accident [1904.5(b)(2)(vii)] because the exemption for motor vehicles applies only to moving vehicles. And because changing a tire has been ruled a work related activity the exemption on personal tasks outside assigned working hours [1904.5(b)(2)(v)] would not apply, even if it occurred outside assigned work hours.
Lost Days While Awaiting Drug Test Results
Situation: An employee sustains a minor injury at work
requiring only first aid. The employee undergoes a drug test which the
employer’s policy requires following all work related injuries. Company
policy prohibits the employee from returning to work until test results
are returned to the employer. Normal turn around for test results is
36-48 hours. Must these days be counted as days away from work?
Interpretation: An original interpretation dated April 16, 2007, stated the days must be counted as days away from work since the employer was prohibiting the employee from working. However, upon presenting the question more recently to Federal OSHA the original interpretation was reversed. In the revised interpretation, OSHA stated that classifying injuries or illnesses as cases involving days away from work and cases involving restricted work activity focuses on the employee’s need to recuperate, prevention of exacerbation of the injury or illness, and the inability of the employee to do work. The preamble states that both the count of days away from work and the count of days of restricted work activity are severity measures of the injury or illness.
If days away are assigned entirely for administrative reasons associated with formal company policies, classifying the injury as a case involving days away would not reflect the true severity of the case. If it is clearly stated that the employee in no way needed the time to recuperate and would have been able to perform all of his or her routine job functions, the case should not be recorded as one involving days away from work.
Chemical Inhalation
Situation: An employee breathed chemicals for a moment or two
and felt nauseous. He relaxed for about 15 minutes and felt fine
and went back to work. About 6 hours later, other employees began
to feel anxious because they heard this employee was "overcome" by
hazardous chemicals. The LHCP provided oxygen by mask “just for
comfort and relaxation" for these employees, including the one who felt
nausea earlier in the day.
Would OSHA consider this medical treatment for a work related event for the employee who was initially exposed to the chemical? What about the employees who experienced anxiety because of the event?
Interpretation: In the case of the employee who experienced the nausea OSHA has left no doubt the case is recordable. If an employee who experiences symptoms from a work related event is given oxygen the case is recordable. As for the employees who experienced the anxiety, at this writing the interpretation is that these are also recordable since the employees experienced symptoms. The question has been posed to OSHA again and we are awaiting a response.
Unused IV
Situation: An employee suffers a work related injury and is
taken to the hospital by ambulance. In route to the hospital the
ambulance attendant inserted an IV just in case intravenous medication
is required once he arrives at the hospital. Medication was not needed
so the IV was never used, but instead was removed by hospital staff. Is
this medical treatment which would make the case recordable?
Interpretation: As long as no fluid is transferred then there has been no medical treatment.
Injury While Treating an Injury
Situation: An employer injured an arm and was given first aid
treatment with a bandage. The bandage caused an infection to that arm
injury. Would this be a new case or a continuation of the first?
Interpretation: Consider the worst outcome. In this case the first aid treatment that turned into an infection would be recorded as one case.
Tired Due to Hospital Visit
Situation: An employee was injured at work, taken to the
emergency room and spent the entire day and night there awaiting
treatment. Only first aid was given. The next day, the employee was so
tired he missed the day of work. Would the lost workday make the case
recordable?
Interpretation: If the employee was directed by the attending
physician or the employer to take the day off to recuperate, the case
should be recorded as one involving a day away from work. If however,
if it was the employee who decided he couldn’t work because he was
tired, the employer is not obligated to count that as a day away. As
discussed on page 5969 of the preamble to the recordkeeping rule, the
employee is not the decision maker in the recordkeeping process. The
employer and or the physician must decide. If the employer agrees with
the employee’s decision, then they should count the day.
Missed Work Due to Test Prep
Situation: An employee suffered a work related injury and
needed a CAT scan. The employee was required to take a bowel prep which
gave him severe diarrhea resulting in a day away from work. The CAT
scan and bowel prep were necessary as a diagnostic for the work related
injury. Would the bowel prep be a new case?
Interpretation: No, the original injury and bowel prep would be one case OSHA refers the reader to FAQ 7-3 which states: If an employee dies during surgery made necessary by a work-related injury or illness, is the case recordable? What if the surgery occurs weeks or months after the date of the injury or illness?
Answer to FAQ 7-3: If an employee dies as a result of surgery
or other complications following a work-related injury or illness, the
case is recordable. If the underlying injury or illness was recorded
prior to the employee's death, the employer must update the Log by
lining out information on less severe outcomes, e.g., days away from
work or restricted work, and checking the column indicating death.
Injury Due to Overcompensation
Situation: An employee hurt her left arm at work resulting in a
recordable injury because of restrictions. Her restrictions caused her
to favor the injured arm resulting in overuse of her right arm. She
was then placed on right arm restrictions. Is this a new case?
Interpretation: We asked this question in 2005 and were told
this would be two separate cases. This earlier interpretation was
confirmed recently by the following response from OSHA: The development
of an injury to the right arm is a new case, therefore this would be
considered two separate injuries because the employee has not previously
experienced a recorded injury or illness of the same type that affects
the same part of the body with in the meaning of 29 CFR 1904.6.
Summary
OSHA has been quite consistent with interpretations as can be
seen by the few examples provided. There are other interpretations
which may be useful to those charged with the responsibility of
maintaining OSHA injury and illness records. You can go to the OSHA web
site or contact the consultants at CTJ Safety Associates.
Interpretations are also available on the CTJ Safety Keyword Index for OSHA Recordkeeping.

Guidance on the Use of Chemical Countermeasures
on Inland Oil Spills: By Scott Harris, PhD, MPH
The
U.S. Environmental Protection Agency (USEPA) recognizes the major role
of local government responders, such as firefighters, as the first
line of defense for mitigating threats to public health and the
environment from spills of oil and hazardous substances, and tries to
provide them with the tools necessary to safely and effectively
mitigate such incidents. Chemical countermeasures (CCMs) are one
of those tools, but their use must be authorized and carefully
managed. This article describes that process where countermeasures
are proposed for use on inland events such as fuel spills that may
affect navigable waters. These may include surface waters and
conduits to them, including road ditches and storm drains, though the
exact definition remains in flux.
EPA
defines CCMs as “any element, compound, or mixture that coagulates,
disperses, dissolves, emulsifies, foams, neutralizes, precipitates,
reduces, solubilizes, oxidizes, concentrates, congeals, entraps, fixes,
makes the oil more rigid or viscous, reduces the harmful effects or
otherwise helps remove the oil from the environment.” This
includes biological additives, dispersing agents, surface washing
agents, surface collecting agents, burning agents and any other
miscellaneous oil spill control agents.
For spills that have the potential to reach navigable waters,
either directly or by runoff, the CCM must be listed on the Product Schedule found at Subpart J of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The Product Schedule Q&A
can answer many typical questions, and you can also verify that a
product is on the Schedule by calling 202-260-2342. The NCP Product Schedule Notebook contains detailed information on listed products.

Experimental Investigations of Ergonomic Interventions for
Scaffolding Operations at Nuclear Power Plant Facilities
In the previous News-E article, NC State Occupational Safety and Ergonomics Program reported on the methodology of an OSHERC-supported pilot project to assess the effectiveness of various ergonomic interventions in scaffolding operations conducted at nuclear power plants as part of maintenance. We planned to conduct multiple experiments to determine whether alternative designs of materials and equipment for securing scaffold planks to frames and for coupling tubes as part of scaffold frames might reduce operator exposure to ergonomic risk factors and increase task performance.
Previous scaffolding work analyses, conducted in collaboration
with personnel from the Ergonomics Center of North Carolina, revealed
such tasks to require extreme worker posture positions (spinal forward
flexion and kneeling) as well as high-forces at the hands and wrists in
repetitious movements.
In our experiments, we compared the current use of 9-gauge steel
wire for plank-to-frame tie-down (see Fig. 1(a)) with the use of
high-strength industrial zip ties (250 lbs. test). We also made
comparison of existing scaffolding tube couplers (see Fig. 1(b)),
integrating a nut and bolt for fastening, with a new tube coupler
integrating a lever clamping mechanism and handle lock. We expected the
zip ties to reduce the need for workers to assume kneeling postures
and to eliminate the need for high-force twisting of wires with pliers
when securing planks to frames. The ties were also expected to reduce
task time. Beyond this, we expected the new tube couplers to eliminate
repetitious hand motions, required in using a ratchet to fasten old
couplers, and that they would be quicker to apply to frames. Field
experiments were conducted at a nuclear power plant training facility
with actual scaffold builders and scaffolding materials. A three-day
test period was used to capture scaffold builder joint-angle data (with a
goniometer) in the plank tie-down and tube coupling tasks as well as
task completion time data. Extensive worker surveys were conducted
during test trials and at the close of the data collection period.

Fig. 1 (b). Existing scaffold tube couplers. |
Preliminary results revealed the use of the industrial zip ties to dramatically reduce task time from approximately 8 min. (for securing eight plank ends with steel wire) to 4 min. The proportion of task time spent in a kneeling posture was also reduced and the ties eliminated extreme pronation and supination of the forearms relative to using steel tie-wire. The new scaffold tube couplers reduced task time by approximately 0.5-1 min. (over the course of completion of eight tube connections). There was also a substantial reduction in wrist flexion, extension, abduction and adduction as compared to using the old couplers requiring nut ratcheting. Finally, subjective surveys revealed the majority of participants to find the zip ties to be easier and faster to use and that the new couplers with a lever for clamping were quicker and required far less force to secure to frames. Detailed statistical analysis of this data and electromyography responses is to be conducted over the next several months.
Dr. Kaber will be offering a new Continuing Education Ergonomics course at the Winter Institute in St. Pete's Beach, FL, February 2010. Watch for it soon on the website.

Brian J. Caveney, MD, JD, MPH named Editor-in-Chief of
Occupational Injuries and Illnesses
Brian J. Caveney, MD, JD, MPH, Assistant Professor in the Division of Occupational and Environmental Medicine at Duke University Medical Center, was named the Editor-in-Chief of Occupational Injuries and Illnesses. OII is a three volume treatise published by Matthew Bender (Lexis-Nexis) targeted to occupational health professionals, the insurance industry, and attorneys dealing in workers' compensation claims, with particular focus on elements of causation, work-relatedness, and resulting impairment of occupational injuries and illnesses.
K01 Study Funded
Dr. Douglas Myers, an Assistant Professor in the Division of Occupational and Environmental Medicine, Department of Community and Family Medicine at Duke University, was recently awarded funding for his K01 study, “Preventing Blood and Body Fluid Exposures during Surgical Procedures”. In this study, Dr. Myers will evaluate intervention efforts to reduce the risk of blood and body fluid (BBF) exposures in operating rooms. Dr. Myers also recently had an article accepted for publication in the American Journal of Industrial Medicine entitled “Informal Social Status among Coworkers and Risk of Work-related Injury among Nurse Aides in Long-term Care”. In that study, he utilized social network measures to study the risk of work-related injury as a function of one’s social rank in an informal hierarchy among nurse aides. As a part of his study of BBF exposures in the operating room, Dr. Myers will build upon his background in sociology to examine whether greater familiarity among surgical team members produced by repeatedly working together leads to greater coordination and lowers risk of BBF exposures.

ABSTRACT:
Introduction: Ocular and musculoskeletal illness among computer
professionals has been a topic in occupational health research for many
years. Computers are revolutionizing the workplaces of India, and their
use will continue to grow. Concerns have been expressed about the
potential health effects associated with computer use in this setting,
yet current prevalence data are lacking in India. The bulk of
literature available on this problem is in the West with few studies
done in India.
Methods: Two IT Industries of Vadodara were selected by random
sampling. Out of 200 computer professionals 160 consented and completed
an occupational and medical health questionnaire.
Results: The prevalence of musculoskeletal complaints in the upper
extremities and ocular complaints of pain and watering of the eyes
increased with increasing length of shift and duration (years) of
computer work.
Conclusions: Musculoskeletal and ocular illness among India computer
professionals increases with length and duration of employment.
Ergonomic intervention is critical to reducing illness and increasing
job satisfaction.
Practical ergonomic interventions are discussed.

ABSTRACT:
Background: According to the BLS, diagnostic medical sonographers held about 37,000 jobs in 2002 in the US. Due to the upper extremity-intensive nature of this occupation, sonographers are at risk for developing work-related musculoskeletal disorders. A majority of the studies have identified the main factors leading to musculoskeletal disorders as forceful prolonged grip of the transducer, awkward upper body postures, and static contractions of the upper limbs.
Purpose: The purpose of this study was to assess the reduction in musculoskeletal disorder physical risk factors by using interventions when performing ultrasound scans. Sonographers at the host site frequently visited Employee Health with reports of pain. Researchers worked in concert with the host site’s ergonomics sonography committee and industrial designers to develop interventions. These consisted of transducer covers and elbow supports for the sonographers as well as breast and pannus supports for the patients.
Testing:. Field testing was designed with an intervention and control group with pre and post intervention measures. Approximately three months later, a follow-up exposure assessment was to be conducted. During this assessment, the experimental group was to perform their typical work tasks with the interventions. The control group was to perform their tasks as normal. Postures during scanning tasks were to be assessed using the PATH methodology and muscle activity was to be sampled using surface electromyography.
Participants: Employees at the host site, who work in the various sonography clinics were invited to participate in this study. Participants were informed of the benefits and risks to participating in this study and were assigned to the intervention or control group. Ten subjects were recruited in each group, respectively.
Results: Although many of the interventions did not meet the needs of the sonographers, this study led to other solutions using a participatory approach. The researchers have redesigned the interventions and developed a new intervention to assist with gripping the transducer – a flexible ring. The host site sonographers are pleased with the device and have requested nine more. A proposal to formally test the transducer ring as an ergonomic intervention has been submitted and is under review for funding.
