Keeping Workers Safe Through Anthropometric Research
Safety at work can depend on an effective or comfortable fit between the physical workplace or the tools of work, and the worker. A seatbelt becomes impractical if it can’t be latched securely or comfortably. The safety that firefighters’ gloves provide is compromised if the gloves are too big, hampering dexterity and movement in a hectic and physically risky situation. Whatever the example of fitting today’s workplace to the worker, one thing is certain—anthropometric research can help. Anthropometry is the science of defining human body dimensions and physical characteristics. NIOSH conducts anthropometric research to prevent work-related injuries and deaths by studying how work spaces and equipment fit today’s diverse worker population. This includes the fit of machines, vehicles, and personal protective equipment (PPE).
Although some anthropometric data have been published in recent years based on the body sizes and shapes of modern military personnel, most data available today were collected in the 1950s and 1970s from military personnel and the general population from that era. These decades-old data do not represent, on average and collectively, the sizes and body types of today’s workers, who are much more diverse in age, gender, and ethnicity. NIOSH research has shown workers have unique shapes and sizes for specific occupations. For instance, research revealed that truck drivers are heavier and wider than the average worker in the U.S. population, which has prompted many in the truck manufacturing industry to redesign truck cabs to support truck driver safety.
The differences in the body sizes and shapes of today’s workers when compared to previously available anthropometric data, as well as limited availability of proper fitting PPE, can contribute to worker injuries and fatalities. The anthropometric research we’re conducting will support worker safety and health by helping designers and manufacturers in:
- re-designing equipment and workspaces to better meet the needs of workers;
- developing PPE that fits and works better; and
- making PPE more comfortable.
Using anthropometric data to design machines, vehicles, and PPE that better fit today’s workers is an important part of Prevention through Design (PtD). An example of PtD is Dr. Ziqing Zhaung’s research on head-and-face anthropometry and 3D head models of industrial workers, which was incorporated into technical specifications of the International Organization for Standardization’s (ISO) standards for testing new respirator face pieces. Moreover, an article written by NIOSH’s Dr. Hongwei Hsiao, which has been among the most-read articles in Human Factors in the past few years, gives several other examples of how equipment and PPE can be redesigned to improve the safety and health of workersexternal icon. Taken together, these research outputs have assisted in the development of better-fitting PPE for the workplace, with manufacturers reporting the use of NIOSH data in design efforts of everything from hard hats to fall protection harnesses.
Most of NIOSH’s research on workers’ physical measures takes place in the NIOSH Anthropometry Labs. The Morgantown and Pittsburgh labs were developed in 1995 and 2001 respectively, and they are two of only several in the world with advanced technologies for collecting highly accurate anthropometric data. Computer-generated human models are available for analysis through 3-dimensional digital scanning in the lab. Full-body, head, and foot scanners as well as a hand-held scanning device for stationary objects are available and can produce high resolution scans within seconds.
NIOSH also has a Mobile Anthropometry Lab equipped with a whole body, foot, hand, and head scanner, all inside a 30-foot long trailer. This lab on wheels allows researchers to reach workers across the nation. The Mobile Anthropometry Lab has traveled across the United States, making stops in Boise, ID; Fort Worth, TX; New Haven, CT; Phoenix, AZ; Minneapolis, MN; Richmond, VA; and Tallahassee, FL.
These two labs were instrumental in our most recent research. As you may recall from the February issue of eNews, I shared some of NIOSH’s 2015 priorities. One of those goals was to develop and publish a summary of truck driver and firefighter anthropometry data on the NIOSH website for use in equipment and workspace design. I am delighted to report that NIOSH has made significant progress toward achieving this goal.
NIOSH recently released a summary of results from the first-ever federal anthropometric study of U.S. truck drivers. This document can help truck manufacturers improve the ergonomic design of truck cabs to better fit the sizes and shapes of today’s drivers. A truck cab designed on up-to-date truck driver body size and shape data supports a safer work environment for its operator. NIOSH gave data from this research to several truck manufacturers, which are using it to redesign truck cabs.
As for firefighter anthropometric research, NIOSH’s most recent studies have assessed fire apparatus seat and seat belt designs, and the fit of glovespdf iconexternal icon used in structural firefighting to accommodate current firefighters. As a result, NIOSH has given apparatus manufacturers and standards committees recommendations for seatbelt length, seat width and spacing, and head supports. NIOSH has also proposed an improved sizing scheme for structural firefighting gloves. A summary of firefighter anthropometry data was published in Human Factorspdf iconexternal icon, and NIOSH expects to publish the detailed data on its website by the end of 2015.
With support from stakeholders and partners, NIOSH has finished collecting data on emergency medical services workers, and it is gearing up to collect data on law enforcement officers. We expect these study findings will help identify design improvements for work vehicles and PPE.
Our anthropometric research gives us significant opportunities to prevent injuries through the concept of Prevention through Design. This research also takes our findings and allows them to be applied to practical uses outside the Institute. Working with manufacturers, standards committees, trade associations, labor organizations, employers, and workers, our research can be adopted in the workplace, so that together we can help ensure workers’ safety and health in today’s places of employment.

Lead Exposure from an E-Scrap Recycling Facility Can Transfer to the Home
Recycling of used electronics (E-scrap) is an emerging area of concern as a source of occupational exposures among workers, and as a source of take-home exposures. In evaluating an Ohio e-scrap facility, described in the July 17 Morbidity and Mortality Weekly Report (MMWR), NIOSH researchers found that take-home contamination and lead exposure can occur when dust is transferred from the workplace to the home. To read the full report, go to https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6427a3.htm?s_cid=mm6427a3_e. For more information on occupational exposures at e-scrap facilities go to http://blogs.cdc.gov/niosh-science-blog/2014/09/30/escrap/.

The goals were edited and reduced in number to better reflect accomplished goals and the level of effort currently available in the nation to address the remaining priorities. An updated literature review lists documents that helped advance the original goals. The council is interested in comments on the agenda and in additional documents that should be added to the literature review. Contact the NORA Coordinator with any comments.
News from Our Partners
Connecticut Program Announces Campaign on TCE Risks at Childbearing Age
The Connecticut Department of Public Health’s Occupational Health Program has launched a campaign to educate employers and workers who use trichloroethylene in their workplaces about the increased risk to women of childbearing age from low-level exposure to the chemical. The health alert can be found at http://www.ct.gov/dph/lib/dph/environmental_health/eoha/pdf/tce_health_alert_feb_2015c.pdfpdf iconexternal icon. The program cites recent toxicology reviews by the U.S. Environmental Protection Agency that have indicated significant risks to fetal development when pregnant workers are exposed to airborne trichloroethylene (TCE) concentrations as low as 1.5 parts per billion.
Study by New Hampshire Surveillance Program on Injuries and Underreporting
A recent study by the New Hampshire Occupational Health Surveillance Program of the New Hampshire Division of Public Health Services focused on injury underreporting and the role of workers’ compensation in paying for the treatment of work-related injuries. The study focused on survey respondents who were working for wages when they had been injured at work seriously enough to require medical attention. Nearly half of these survey respondents used workers’ compensation to pay for their injury. Other payer sources included personal insurance plans, Medicare and Medicaid combined, and those only partially paid for by workers’ compensation. The report can be found at http://www.dhhs.nh.gov/DPHS/hsdm/ohs/documents/brfss-wri-underreporting-2015.pdfpdf iconexternal icon.
OSHA Directive Updates Inspection Procedures for Protecting Workers From Tuberculosis in Healthcare Settings
The Occupational Safety and Health Administration updated instructions for conducting inspections and issuing citations related to worker exposures to tuberculosis in healthcare settings. This instruction incorporates guidance from the Centers for Disease Control and Prevention report, “Guidelines for Preventing the Transmission ofMycobacterium Tuberculosis in Health-Care Settings, 2005 (https://www.cdc.gov/mmwr/pdf/rr/rr5417.pdfpdf icon).” This directive also covers additional workplaces regarded as healthcare settings, such as sites where emergency medical services are provided and laboratories handling clinical specimens that may contain M. tuberculosis. More information on hazard recognition and solutions for reducing or eliminating the risks of contracting tuberculosis is available on OSHA’s Tuberculosis Safety and Health Topics page https://www.osha.gov/SLTC/tuberculosis/index.htmlexternal icon.
Horse Breeder Falls 11–12 Feet from Hayloft When Throwing Hay Bale—Michigan
A horse breeder died when his coat became entangled in the twine of a bale he was physically throwing from the hayloft. He fell 11–12 feet from the loft onto hard-packed dirt. Emergency responders arrived and transported him to a local hospital, where he died the next day. /niosh/face/stateface/mi/12mi281.html
Fire Fighter Fatality Investigation and Prevention Program Reports
Pump Operator/Paramedic Suffers Sudden Cardiac Death After Physical Fitness Training—Texas
On November 16, 2014, a 40-year-old male career pump operator/paramedic responded to a standby call and later ran 1 mile and lifted weights in the gym during his 24-hour shift. After performing fitness training, the pump operator went into one of the fire station’s restrooms. A crew member entered the restroom about an hour later and found the pump operator collapsed on the floor. After further assessment, the pump operator was declared dead on the scene. /niosh/fire/reports/face201423.html
Fire Engineer Suffers Sudden Cardiac Death at Shift Change—California
On January 20, 2014, a 49-year-old male career fire engineer was scheduled to work his regular 24-hour shift. This would have been his third consecutive 24-hour shift, because he had volunteered to work a 24-hour overtime shift the day before. During the first 48 hours, the fire engineer responded to seven medical calls, none of which required heavy physical exertion. When the engineer did not attend the third shift change meeting, crew members found him unresponsive in his bunk. NIOSH investigators concluded that an arrhythmia probably triggered his sudden cardiac death. /niosh/fire/reports/face201501.html
Health Hazard Evaluation (HHE) Program Update
Recommendations Provided to a Poultry Processing Plant
HHE Program investigators found a high percentage of poultry processing employees with hand activity and force above recommended levels—34% of tested employees had evidence of carpal tunnel syndrome. To help protect against musculoskeletal disorders and traumatic injuries, investigators recommended following OSHA poultry processing guidelines, redesigning job tasks, and using a job rotation schedule. A link to this final report is available at /niosh/hhe/whats_new.html.
Evaluation of Tuberculosis Transmission at an Elephant Sanctuary
The HHE Program evaluation found that improvements could be made to ventilation systems in barns at an elephant refuge where elephants with active tuberculosis disease were kept, and to employee work practices and personal protective equipment. HHE Program investigators recommended ways to treat elephants with active tuberculosis disease, perform employee tuberculin skin tests, and improve employee respirator use. This final report is available at /niosh/hhe/whats_new.html.

This Month In History
This month, 27 years ago . . .
Richard A. Lemen, then-director of the NIOSH Division of Standards Development and Technology Transfer, testified before the U.S. Department of Labor about the Occupational Safety and Health Administration’s proposed rules on air contaminants. He began his statement by saying, “We agree there is an urgent need to update the current air contaminant standards because they represent exposure limits based on data available prior to 1968.”
NIOSH advised that the “chemical universe” in the proposed rules includes all chemicals with NIOSH-identified recommended exposure limits. To support this position, NIOSH provided 179 comprehensive scientific analyses. To read the full statement go to /niosh/docket/archive/pdfs/NIOSH-240/1988policyStatement.pdfpdf icon.
