CONN-OSHA Annual Survey Shows 69,500 Injuries and Illnesses in Connecticut Workplaces in 2006 

A total of 69,500 injuries and illnesses were reported in Connecticut’s public and private sector workplaces during 2006, according to the Annual Survey of Occupational Injuries and Illnesses compiled by the Department of Labor’s CONN-OSHA division. The total translates into a rate of 5.2 cases per 10 equivalent full-time workers. This compares to a rate of 5.5 injuries and illnesses per 10 equivalent full-time workers in 2005.  The number of cases decreased from a total of 74,300 in 2005. This 6% drop in the number of cases over the year was offset by a 1% slump in the number of hours worked from 2005 to 2006. 

The private sector rate was 4.8 in 2006, compared to 5.0 in 2005.  The public sector – state government and local municipal government operations – was measured at 7.9 cases per 10 equivalent full-time workers, a significant decrease compared to the 2005 rate of 9.2. 

Revisions to the Survey

Change in industry classifications: Beginning with the 2003 reference year, the Survey of Occupational Injuries and Illnesses began using the 2002 North American Industry Classification System (NAICS).  Prior to 2003, the survey used the Standard Industrial Classification (SIC) system. The substantial differences between these systems result in breaks in series for industry data.  While industry comparisons are now possible among reference years 2003 through 2006, users are advised against making comparisons to results from years prior to 2003.  The only comparisons possible linking 2002 data to subsequent years are those at the sector totals mentioned above for private sector, public sector and all industry levels. 

Connecticut Public Sector

The incidence rate for Connecticut’s state and local government employees was measured at 7.9 cases per 10 equivalent full-time workers in 2006, down significantly from the rate of 9.2 registered in 2005. Local municipal government operations contributed 10,200 occupational injuries and illnesses to the state-wide total and had a rate of 8.7 cases per 10 equivalent full-time workers. State government employees, meanwhile, suffered 3,400 injuries and illnesses for a rate of 6.2. The rate of total recordable cases in the public sector is significantly higher than the private sector rate of 4.8 primarily due to hazardous occupations unique to the public sector such as police officers and firefighters. Overall, the public sector contributed 13,600 of Connecticut’s 69,500 work-related injuries and illnesses (20%) while providing 14% of the employment. 

National Rates and Totals

A total of 4.1 million nonfatal injuries and illnesses were reported in private industry workplaces during 2006, resulting in a rate of 4.4 cases per 10 equivalent full-time workers, according to the Bureau of Labor Statistics, U.S. Department of Labor.  The rate of injuries and illnesses declined from 4.6 cases per 10 equivalent full-time workers in 2005, and is the lowest rate recorded since the inception of the Survey of Occupational Injuries and Illnesses in 1972.  Approximately 2.1 million injuries and illnesses were cases with days away from work, job transfer or restriction; that is, they required recuperation away from work, transfer to another job, restricted duties at work, or a combination of these actions.  The remaining 2.0 million injuries and illnesses were other recordable cases that did not result in time away from work. The incidence rate for cases with days away from work, job transfer or restriction was 2.3 cases per 10 workers, and the rate for other recordable cases was 2.1.  Both of these rates decreased by 0.1 cases per 10 equivalent full-time workers from 2005. 

Industry Comparisons

To account for differences in industry employment and hours worked, the Bureau of Labor Statistics calculates incidence rates relating the number of injuries and/or illnesses to employee hours in the workplace. This formula can be found in footnote 1, table 1. Every employer is categorized in one of 20 industry sectors which make up the North American Industry Classification System (NAICS). The 2006 Connecticut injury and illness rates ranged from 7.9 cases per 10 equivalent full-time workers in both Construction as well as State and Local Government, to 0.9 in Finance and insurance. 

Highest Rate Industries - Table 1

An examination of the industries with the 10 highest rates of occupational injury and illness shows that the public sector continues to be the most hazardous. State and local government operations had the six highest rates: local government waste management and remediation services (32.7 cases per 10 equivalent full-time workers), local government fire protection (23.9), state government hospitals (23.1), local government police protection (20.5), local government public works – street & highway (19.0), and state government ambulatory health care services (14.7).   These were followed by private sector plumbing, heating and air-conditioning contractors (13.7), state government nursing and residential care facilities (13.6), and private sector primary metal manufacturing (12.9). Private sector nursing and residential care facilities (11.3) rounds out the top-ten list. 

“DART” Cases - Table 2 

More than half of the 69,500 cases in 2006 (36,100) were cases involving days away from work, restriction or job transfer. These cases required recuperation away from work, transfer to another job, restricted duties at work, or a combination of these actions. Of these cases, the majority (22,900) involved days away from work with or without job transfer or restriction while the remainder (13,300 cases) involved transfer or restriction only. 

Injuries and Size-Class - Table 3

Of the 69,500 nonfatal injuries and illnesses in 2006, 65,700 (95%) were traumatic injuries cases as opposed to the more latent occupational illness cases. Injury and illness rates are generally higher for mid-sized establishments employing 50 to 249 workers than for smaller or larger establishments. However, this pattern does not hold within certain industry divisions. 

Illnesses - Table 4

There were about 3,800 newly reported cases of occupational illnesses in Connecticut in 2006, just over 5% of the total number of injuries and illnesses reported statewide. The manufacturing sector (1200), followed by the education and health services sector (800), and state and local government (600) contributed the bulk of the illness cases.  These three sectors combined accounted for 2,600 occupational illnesses in 2006, or 68% of the total. 

Case and Demographic Details - Tables 9-16

For those cases which involved days away from work with or without job transfer or restriction (22,900 cases in Connecticut in 2006) the Annual Survey of Occupational Injuries and Illnesses generates estimates of the demographic characteristics of the workers involved as well as the case characteristics, or circumstances, detailing the injury or illness. 

Demographic characteristics include:

  • Occupation
  • Age
  • Gender
  • Length of service
  • Race or ethnic origin

Case characteristics – the survey uses four case characteristics to describe each incident that led to an injury or illness that involved one or more days away from work.  These characteristics include:

  • Nature – the physical characteristics of the disabling injury or illness, such as cuts/lacerations, fractures, or sprains/strains;
  • Part of body affected – directly linked to the nature of injury or illness cited, such as back, finger, or eye;
  • Event or exposure – the manner in which the injury or illness was produced or inflicted, such as falls, overexertion, or repetitive motion;
  • Source – the object, substance, exposure, or bodily motion that directly produced or inflicted the disabling condition, such as chemicals, vehicles or machinery.

Survey Notes 

The Survey of Occupational Injuries and Illnesses is a Federal/State program in which employer reports were collected from about 195,200 private industry establishments nationwide in 2006 and processed by State agencies cooperating with the Bureau of Labor Statistics (BLS). The Connecticut DOL sampled approximately 4,500 establishments in the private and public sectors. The survey measures nonfatal injuries and illnesses only. The survey excludes the self-employed; farms with fewer than 11 employees; private households; Federal government agencies; and, for national estimates, employees in State and local government agencies. The annual survey provides estimates of the number and frequency (incidence rates) of workplace injuries and illnesses based on logs kept by private and public sector employers during the year. These records reflect not only the year’s injury and illness experience, but also the employers’ understanding of which cases are work related under recordkeeping rules revised by the Occupational Safety and Health Administration (OSHA), U.S. Department of Labor and made effective on January 1, 2002. Effective January 1, 2004, OSHA further revised the recordkeeping rules by adding hearing loss as a separate identified illness category. 

Data in this release mark the fourth time for the Survey of Occupational Injuries and Illnesses that establishments are classified by industry based on the 2002 North American Industry Classification System Manual (NAICS). NAICS recognizes hundreds of new businesses in the United States economy, most of which are in the service providing sector. Establishments are classified into a detailed industry based on the production processes and provided services. As a result of the conversion to NAICS, the estimates by industry from the 2003 thru 2006 surveys are not comparable with those from prior years.  

Occupational injury and illness data for coal, metal, and nonmetal mining and for railroad activities were provided by the Department of Labor’s Mine Safety and Health Administration (MSHA) and the Department of Transportation’s Federal Railroad Administration (FRA), respectively. MSHA has not adopted the revised OSHA recordkeeping requirements for 2006.Therefore, estimates for coal, metal, and nonmetal mining are not comparable with estimates for other industries. FRA adopted the revised OSHA recordkeeping requirements in June 2003. Therefore, estimates for railroad activities for 2006 can be compared to estimates for other industries. However, estimates for railroad activities in 2006 should not be compared to estimates for railroad activities from years prior to 2004.  

The survey estimates of occupational injuries and illnesses are based on a scientifically selected probability sample, rather than a census of the entire population. Because the data are based on a sample survey, the injury and illness estimates probably differ from the figures that would be obtained from all units covered by the survey. To determine the precision of each estimate, a standard error was calculated. The standard error defines a range (confidence interval) around the estimate. The approximate 95-percent confidence interval is the estimate plus or minus twice the standard error. The standard error also can be expressed as a percent of the estimate, or the relative standard error. For example, the national 2006 incidence rate for all occupational injuries  and illnesses of 4.4 per 10 full-time workers in private industry has an estimated relative standard error of less than 0.5 percent.  The 95-percent confidence interval would be 4.4 plus or minus 1.0 percent (2 times 0.5 percent) or 4.36 to 4.44.  One can be 95% confident that the “true” incidence rate falls within this confidence interval. A relative standard error was calculated for each estimate from the survey and is be available on the BLS Internet site at http://www.bls.gov/iif/home.htm

The number of injuries and illnesses reported in any year can be influenced by the level of economic activity, working conditions and work practices, worker experience and training, and the number of hours worked.  The data also are subject to nonsampling error. The inability to obtain information about all cases in the sample, mistakes in recording or coding the data, and definition difficulties are examples of nonsampling error in the survey. Nonsampling errors are not measured. However, BLS has implemented quality assurance procedures to minimize nonsampling error in the survey.
