Cleaning Products and Work-Related Asthma, 10 Year Update.

OBJECTIVE: To describe the frequency of work-related asthma (WRA) and characteristics of individuals with exposure to cleaning products 1998 to 2012, compared with 1993 to 1997. METHODS: Cases of WRA from products used for cleaning or disinfecting surfaces were identified from California, Massachusetts, Michigan (1998 to 2012), New Jersey (1998 to 2011), and New York (2009 to 2012). RESULTS: There were 1199 (12.4%) cleaning product cases among all 9667 WRA cases; 77.8% women, 62.1% white non-Hispanic, and average age of 43 years. The highest percentages worked in healthcare (41.1%), and were building cleaners (20.3%), or registered nurses (14.1%). CONCLUSIONS: The percentage of WRA cases from exposure to cleaning products from 1998 to 2012 was unchanged from 1993 to 1997 indicating that continued and additional prevention efforts are needed to reduce unnecessary use, identify safer products, and implement safer work processes.

Reported injury, hospitalization, and injury fatality rates among New Jersey adolescent workers.

BACKGROUND: Workplace injuries are a public health concern, including among adolescents and young adults. Secondary school career-technical-vocational education related injuries are mandated by code under jurisdiction of New Jersey Department of Education to be reported online to New Jersey Safe Schools Program. These are the only U.S. law-based surveillance data for young workers in secondary school career-technical-vocational education. New Jersey Department of Health's hospitalization and fatality records provide additional information about other secondary school career-technical-vocational education and non- secondary school career-technical-vocational education related injuries not necessarily reported to New Jersey Safe Schools Program. This report compared data available to the New Jersey Department of Health and New Jersey Safe Schools Program on injuries among young workers ages 14-21 years. METHODS: Annual work-related hospitalizations, 2007-2016, were abstracted from hospital discharge data. Denominator data from the U.S. Bureau of Labor Statistics was used to estimate annual crude rate of hospitalizations per 100,000 employed persons. Hospitalization rates were stratified by demographic data from the U.S. Bureau of Labor Statistics. Hospitalization rates for primary diagnoses and job title/status with ≥2 documented cases were reported. Annual crude fatality rates per 100,000 full time equivalent workers, age ≥ 16 years, were estimated for 1990-2016 using annual average full time equivalent workers and the U.S. National Institute Occupational Safety and Health's Employed Labor Force Query System as denominator. RESULTS: Annual crude hospitalization rates decreased over time. Hospitalization and fatality rates were higher among young adult workers ages 19-21 years; non-Hispanic Whites; and, males. Percent fatality for ages 19-21 years was greater than ages 14-17 years and 18 years. Declines in hospitalization rates corresponded to decreases in reported injuries among career-technical-vocational education students. Age distribution varied slightly between hospital discharge data and New Jersey Safe Schools Program data. CONCLUSION: Hospitalization and fatality rates were higher among males than among females, possibly reflecting a tendency for males to engage in riskier jobs than females. Understanding injury disparities can inform public health prevention efforts. Trainings/interventions should aim at addressing the most frequently diagnosed conditions or nature of reported injuries, within those most impacted career clusters like sales/restaurant workers.

Evaluation of a state based syndromic surveillance system for the classification and capture of non-fatal occupational injuries and illnesses in New Jersey.

BACKGROUND: This preliminary study evaluates a real-time syndromic surveillance system to track occupationally-related emergency room visits throughout New Jersey. METHODS: Emergency Department (ED) chief complaint fields were evaluated from 79 of 80 hospitals in NJ in 2014, using work-related keywords and ICD-9 E-codes, to determine its ability to capture non-fatal work-related injuries. Sensitivity analysis and descriptive statistics, were used to evaluate and summarize the occupational injuries identified. RESULTS: Overall, 11 919 (0.3%) possible work-related ED visits were identified from all ED visits. Events with the greatest number of ED visits were slips, trips, and falls (1679, 14%). Nature of injury included cuts, lacerations (1041, 9%). The part of the body most affected was the back (1414, 12%). This work-related classifier achieved a sensitivity of 5.4%, a specificity of 99.8%, and a PPV of 2.8%. CONCLUSIONS: This evaluation demonstrated that the syndromic surveillance reporting system can yield real-time knowledge of work-related injuries.

Surveillance for Silicosis - Michigan and New Jersey, 2003-2011.

CDC's National Institute for Occupational Safety and Health (NIOSH), state health departments, and other state entities maintain a state-based surveillance program of confirmed silicosis cases. Data on confirmed cases are collected and compiled by state entities and submitted to CDC. This report summarizes information for cases of silicosis that were reported to CDC for 2003-2011 by Michigan and New Jersey, the only states that continue to provide data voluntarily to NIOSH. The data for this report were final as of January 8, 2015. Data are presented in tabular form on the number and distribution of cases of silicosis by year (Table 1), duration of employment in occupations with potential exposure to dust containing respirable crystalline silica (Table 2), industry (Table 3), and occupation (Table 4). The number of cases by year is presented graphically (Figure). This report is a part of the Summary of Notifiable Noninfectious Conditions and Disease Outbreaks - United States, which encompasses various surveillance years but is being published in 2016 (1). The Summary of Notifiable Noninfectious Conditions and Disease Outbreaks appears in the same volume of MMWR as the annual Summary of Notifiable Infectious Diseases (2).

Work-Related Unintentional Injuries Associated With Hurricane Sandy in New Jersey.

OBJECTIVE: We aimed to evaluate the occurrence of work-related injuries after Hurricane Sandy potentially related to response and recovery. METHODS: Emergency and hospital discharges (patients aged 18-65 years) with a diagnosis of unintentional injury were obtained from the New Jersey Department of Health. Work-related injuries were identified as those with a workers' compensation payer or other work-related codes. Counties were categorized as high-, medium-, or low-impact areas. Poisson regression analysis was used to compare the rate of work-related injury the year following Sandy landfall with the 3 previous years. RESULTS: Total work-related injuries declined the week immediately after Sandy (rate ratio [RR]: 0.85; 95% confidence interval [CI]: 0.69-1.05) and no overall increase was found in the year after Hurricane Sandy. However, high-impact counties showed an elevated risk of work-related injuries in the first and third quarters after Hurricane Sandy among men, especially for blacks and Hispanics. The greatest excesses occurred in the third quarter after the storm, May to July, for falls (RR: 1.30; 95% CI: 1.08-1.57), cut/pierce injuries (RR: 1.24; 95% CI: 1.09-1.40), struck-by injuries (RR: 1.17; 95% CI: 1.02-1.34), and overexertion (RR: 1.26; 95% CI: 1.10-1.44). CONCLUSIONS: Hospital data suggested an increase in injuries associated with rebuilding and recovery rather than with initial response. Future efforts aimed at prevention should evaluate the mechanisms and circumstances of injury in more detail. (Disaster Med Public Health Preparedness. 2016;10:394-404).

Assessing Barriers to the Use of Fall Protection in Small Residential Construction Companies in New Jersey.

Three focus groups were conducted with residential construction workers from local New Jersey labor organizations to characterize barriers to fall protection use among residential construction contractors who work for companies with fewer than ten employees. Thirty-six residential construction workers volunteered to participate, the average age was thirty-nine years, and twenty-four (67%) were of Hispanic origin. Twelve (33%) of the participants reported having fallen from greater than 6 ft at work and twenty (56%) of the participants had known someone who has fallen from greater than 6 ft. Sixteen (44%) had not been provided with fall protection equipment by their employer and eighteen (50%) reported their current employer had not provided workplace safety training. Factors that created barriers to use of fall protection equipment such as equipment availability, employee/employer relationships, cultural differences, and company size were identified. Results from this study confirm that falls remain a concern among residential construction workers in small companies.

Isocyanates and work-related asthma: Findings from California, Massachusetts, Michigan, and New Jersey, 1993-2008.

BACKGROUND: Isocyanates remain a leading cause of work-related asthma (WRA). METHODS: Two independent data systems were analyzed for the period 1993-2008: (1) State-based WRA case surveillance data on persons with isocyanate-induced WRA from four states, and (2) Occupational Safety and Health Administration (OSHA) Integrated Management Information System (IMIS) isocyanate air sampling results. RESULTS: We identified 368 cases of isocyanate-induced WRA from 32 industries and 678 OSHA isocyanate air samples with detectable levels from 31 industries. Seventeen industries were unique to one or the other dataset. CONCLUSION: Isocyanate-induced WRA continues to occur in a wide variety of industries. Two data systems uncovered industries with isocyanate exposures and/or illness. Improved control measures and standards, including medical surveillance, are needed. More emphasis is needed on task-specific guidance, spill clean-up procedures, skin and respiratory protection, and targeted medical monitoring to mitigate the hazards of isocyanate use.

Assessment of emergency responders after a vinyl chloride release from a train derailment - New Jersey, 2012.

On November 30, 2012, at approximately 7:00 am, a freight train derailed near a small town in New Jersey. Four tank cars, including a breached tank car carrying vinyl chloride, landed in a tidal creek. Vinyl chloride, a colorless gas with a mild, sweet odor, is used in plastics manufacture. Acute exposure can cause respiratory irritation and headache, drowsiness, and dizziness; chronic occupational exposure can result in liver damage, accumulation of fat in the liver, and tumors (including angiosarcoma of the liver). Because health effects associated with acute exposures have not been well studied, the New Jersey Department of Health requested assistance from the Agency for Toxic Substances and Disease Registry (ATSDR) and CDC. On December 11, teams from these agencies deployed to assist the New Jersey Department of Health in conducting an assessment of exposures in the community as well as the occupational health and safety of emergency personnel who responded to the incident. This report describes the results of the investigation of emergency personnel. A survey of 93 emergency responders found that 26% of respondents experienced headache and upper respiratory symptoms during the response. A minority (22%) reported using respiratory protection during the incident. Twenty-one (23%) of 92 respondents sought medical evaluation. Based on these findings, CDC recommended that response agencies 1) implement the Emergency Responder Health Monitoring and Surveillance (ERHMS) system for ongoing health monitoring of the emergency responders involved in the train derailment response and 2) ensure that in future incidents, respiratory protection is used when exposure levels are unknown or above the established occupational exposure limits.

Swimming facilities and work-related asthma.

BACKGROUND: Exposure to chlorinated water in swimming facilities may aggravate preexisting asthma or cause new onset asthma. This may be a particular problem for individuals who work and therefore spend prolonged time at swimming facilities. Chloramines formed by the interaction of chlorine-based disinfection products with the nitrogen in water from human sweat, urine and skin cells are the suspected causal agents. METHODS: Cases were reviewed from the state surveillance systems in California (CA), Michigan (MI) and New Jersey (NJ) to identify individuals with confirmed work-related asthma (WRA) attributed to exposures in swimming pools, water parks or hydrotherapy spas. A standardized method was used to confirm cases. RESULTS: A total of 44 confirmed cases of WRA were identified; 17 from 1994 to 2011 in CA, 15 from 1991 to 2012 in MI and 12 from 1990 to 2011 in NJ. A majority (52.2%) of the cases were new onset; 31.8% secondary to an acute exposure incident and 20.4% to repeated exposure. These represented 0.3-1.6% of all confirmed cases of WRA received during these time periods. Maintenance workers (34.9%) and lifeguards (31.8%) were the most common occupations. CONCLUSIONS: Swimming pool workers were identified from three states where the pool environment was either a trigger of preexisting asthma or associated with new onset of WRA. Regulations to require air monitoring and improvements in ventilation are recommended to reduce exposure levels of chloramines, the presumed etiologic agents. Clinical assessment of patients with asthma should include consideration of the effect on respiratory symptoms from exposures in a swimming pool environment.

Gender differences in work-related asthma: surveillance data from California, Massachusetts, Michigan, and New Jersey, 1993-2008.

OBJECTIVE: To characterize work-related asthma by gender. METHODS: We analyzed state-based sentinel surveillance data on confirmed work-related asthma cases collected from California, Massachusetts, Michigan, and New Jersey during 1993-2008. We used Chi-square and Fisher's Exact Test statistics to compare select characteristics between females and males. RESULTS: Of the 8239 confirmed work-related asthma cases, 60% were female. When compared to males with work-related asthma, females with work-related asthma were more likely to be identified through workers' compensation (14.8% versus 10.6%) and less likely to be identified through hospital data (14.2% versus 16.9%). Moreover, when compared to males, females were more likely to have work-aggravated asthma (24.4% versus 13.5%) and less likely to have new-onset asthma (48.0% versus 56.5%). Females were also more likely than males with work-related asthma to work in healthcare and social assistance (28.7% versus 5.2%), educational services (11.8% versus 4.2%), and retail trade (5.0% versus 3.9%) industries and in office and administrative support (20.0% versus 4.0%), healthcare practitioners and technical (13.4% versus 1.6%), and education training and library (6.2% versus 1.3%) occupations. Agent groups most frequently associated with work-related asthma were miscellaneous chemicals (20.3%), cleaning materials (15.3%), and indoor air pollutants (14.9%) in females and miscellaneous chemicals (15.7%), mineral and inorganic dusts (13.2%), and pyrolysis products (12.7%) in males. CONCLUSIONS: Among adults with work-related asthma, males and females differ in terms of workplace exposures, occupations, and industries. Physicians should consider these gender differences when diagnosing and treating asthma in working adults.

Evaluation of an innovative use of removable thin film coating technology for the abatement of hazardous contaminants.

This study evaluates a new decontamination technique for the mitigation and abatement of hazardous particulates. The traditional decontamination methods used to clean facilities and equipment are time-consuming, prolonging workers' exposure time, may generate airborne hazards, and can be expensive. The use of removable thin film coating as a decontamination technique for surface contamination proved to be a more efficient method of decontamination. This method was tested at three different sites on different hazardous metals. One application of the coating reduced the levels of these metals 90% and had an average reduction of one magnitude. The paired t-tests that were performed for each metal demonstrated that there was a statistically significant reduction of the metal after the use of the coating: lead (p = 0.03), beryllium (p = 0.05), aluminum (p = 0.006), iron (p = 0.0001), and copper (p = 0.004). The Kendall tau-b correlation coefficient demonstrates that there was a positive correlation between the initial levels of contamination and the removal efficiency for all the samples taken from different locations on the floor for each of the three sites. This new decontamination technique worked efficiently, requiring only one application, which decreased exposure time and did not generate any airborne dust.
