CONN-OSHA Annual Survey Shows an Increase in the Number of Injuries and Illnesses in Connecticut Workplaces During 2005

A total of 74,300 injuries and illnesses were reported in Connecticut’s public and private sector workplaces during 2005, a rise of 9% from 2004’s total of 68,200. These data, provided by the Connecticut Department of Labor’s CONN-OSHA division, was compiled from the Bureau of Labor Statistics’ Annual Survey of Occupational Injuries and Illnesses, a standard measure of workplace safety in America. The 9% increase in the number of injuries and illnesses was offset by a boost in the number of employees and hours worked.

In 2005, a rate of 5.5 injuries and illnesses per Published by the Connecticut Department of Labor, Project Management Office0 full-time workers was recorded for workers in Connecticut, compared to 5.2 in 2004.  The private sector incidence rate was recorded at 5.0 in 2005 and 4.8 in 2004. The public sector – state government and local municipal government operations – was measured at 9.2 cases per Published by the Connecticut Department of Labor, Project Management Office0 equivalent full-time workers, compared to the 2004 rate of 8.4. Some states do not have public sector OSHA plans and thus do not record public sector incidence rates. Therefore, comparisons between public and private sector rates are not made on the national level. 

Industry Comparisons

The Bureau of Labor Statistics calculates incidence rates, which relate the number of injuries and/or illnesses to employee hours in the workplace, to account for differences in industry employment and hours worked. 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 2005 Connecticut injury and illness rates ranged from 9.6 cases per Published by the Connecticut Department of Labor, Project Management Office0 full-time workers in Agriculture, forestry, fishing and hunting, to 0.8 in Finance and insurance.   

Connecticut Public Sector

Overall, the public sector contributed 15,300 of Connecticut’s 74,300 work-related injuries and illnesses (21%) while providing 13% of the employment. Local municipal government operations contributed 11,900 occupational injuries and illnesses to the state-wide total and had a rate of Published by the Connecticut Department of Labor, Project Management Office.1 cases per Published by the Connecticut Department of Labor, Project Management Office0 equivalent full-time workers. State government employees, meanwhile, suffered 3,400 injuries and illnesses for a rate of 7.1. Collectively, the incidence rate for Connecticut’s state and local government employees was measured at 9.2 cases per Published by the Connecticut Department of Labor, Project Management Office0 full-time workers in 2005, compared to the rate of 8.4 registered in 2004. The rate of total recordable cases in the public sector is significantly higher than the private sector rate of 5.0 primarily due to hazardous occupations unique to the public sector such as police officers and firefighters.  

National Rates and Totals

A total of 4.2 million nonfatal injuries and illnesses were reported in private industry workplaces during 2005, resulting in a rate of 4.6 cases per Published by the Connecticut Department of Labor, Project Management Office0 equivalent full-time workers, according to the Bureau of Labor Statistics, U.S. Department of Labor.  The rate of injuries and illnesses declined from 4.8 cases per Published by the Connecticut Department of Labor, Project Management Office0 full-time workers in 2004.  Approximately 2.2 million injuries and illnesses 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 2.4 cases per Published by the Connecticut Department of Labor, Project Management Office0 workers, and the rate for other recordable cases was 2.2.  Both of these rates decreased by 0.1 cases per Published by the Connecticut Department of Labor, Project Management Office0 full-time workers from 2004. 

Highest Rate Industries (Table 1)

An examination of the industries with the Published by the Connecticut Department of Labor, Project Management Office highest rates of occupational injury and illness shows that the public sector continues to be the most hazardous. Local municipal government operations had the five highest rates: waste management and remediation services (38.4 cases per Published by the Connecticut Department of Labor, Project Management Office0 equivalent full-time workers), police protection (36.4), public works – street & highway (19.7), fire protection (16.2), and water, sewage and other systems (16.2).   These were followed by private sector couriers and messengers (14.8), state government health care and social assistance (13.7), and private sector nursing and residential care facilities (13.1).  Forging and stamping manufacturing (11.8) and primary metal manufacturing (11.7) round out the top-ten list.

“DART” Cases (Table 2) 

More than half of the 74,300 cases in 2005 (39,900) 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 (23,900) involved days away from work with or without job transfer or restriction while the remainder (16,000 cases) involved transfer or restriction only.

Injuries and Size-Class (Table 3)

Of the 74,300 nonfatal injuries and illnesses in 2005, 69,400 (93%) were injuries that resulted in either lost worktime, medical treatment other than first aid, loss of consciousness, restriction of work or motion, or transfer to another job. 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 4,900 newly reported cases of occupational illnesses in Connecticut in 2005, just under 7% of the total number of injuries and illnesses reported statewide. The manufacturing sector, combined with the education and health services sector, contributed over half of the illness cases. They each had approximately 1,200 occupational illnesses in 2005, or 25% 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 (23,900 cases in Connecticut in 2005) 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 182,400 private industry establishments nationwide in 2005 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.

The 2002 North American Industry Classification System Manual (NAICS) classifies establishments into a detailed industry based on the production processes and provided services. NAICS recognizes hundreds of new businesses in the United States economy, most of which are in the service providing sector. The Survey of Occupational Injuries and Illnesses began classifying establishments by NAICS in 2003. As a result of the conversion to NAICS, the estimates by industry from the 2003 thru 2005 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 2005.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 2005 can be compared to estimates for other industries. However, estimates for railroad activities in 2005 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 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 2005 incidence rate for all occupational injuries and illnesses of 4.6 per Published by the Connecticut Department of Labor, Project Management Office0 full-time workers in private industry has an estimated relative standard error of about 0.6 percent.  The 95-percent confidence interval would be 4.6 plus or minus 1.2 percent (2 times 0.6 percent) or 4.54 to 4.66.  One can be 95% confident that the “true” incidence rate falls within 4.54 to 4.66 (the confidence interval). A relative standard error was calculated for each estimate from the survey and will 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.
