Custodians represent one of the largest occupational groups using cleaning agents, and yet their voices are infrequently heard in relation to the introduction of "green" cleaners and the laws regarding environmentally preferable products (EPP). This study reflects worker voices on use and effectiveness of chemicals, as well as incentives and obstacles for green cleaning programs. Sixty-four custodians and staff participated in 10 focus groups. Data were entered into Atlas Ti and the constant comparative method of qualitative data analysis was used to identify themes. Themes included satisfaction in a "well-done" job, more effort required for job, lack of involvement in EPP selection process, EPP's ease of use for workers with English as a Second Language (ESL), misuse of disinfectants, health complaints, and need for training. This study shows that custodians have a voice, and that improved communication and feedback among all the stakeholders are needed to make the transition to green cleaning more effective.

number of flights per day (adjusted OR 2.0, 95% CI 1.2-3.3 for 3+ versus 1 flights/day, p trend = 0.007) and fewer time zones crossed per flight (adjusted OR 2.0, 95% CI 1.0-3.7 for 0 vs. 2 + time zones/flight, p trend = 0.04) were associated with a higher rate of endometriosis. Conclusions The rate of endometriosis increased with number of flights and decreased with time zones crossed, which might be surrogates for exposures specific to flying a series of short flights during the workday. 0117 NONMALIGNANT DISEASE MORTALITY AMONG STYRENE, FIBREGLASS, AND WOOD DUST EXPOSED WORKERS IN THE REINFORCED PLASTIC BOATBUILDING INDUSTRYAlysha Meyers, Steve Bertke, Avima Ruder. National Institute for Occupational Safety and Health, Cincinnati, Ohio, USA 10.1136/oemed-2014-102362.40 Objectives To further evaluate the association of styrene, fibreglass, and wood dust exposure with non-malignant diseases, we extended follow-up through 2008 for 5203 workers exposed to styrene, fibreglass, and wood dust between 1959 and 1978 at two boat building plants.Method We used a person-years analysis program, LTAS.NET to compute standardised mortality ratios (SMRs) using Washington State and U.S. rates, standardised rate ratios (SRRs), and 95% confidence intervals. SMRs were stratified by exposure category (low or high) and duration of employment category (≤ 1 year, 1+ years). Results Overall, 1206 nonmalignant deaths occurred (WA SMR 1.14, CI 1.08-1.21), with excess mortality for chronic obstructive pulmonary disease (COPD) overall (n = 112, WA SMR 1.61, CI 1.32-1.93), and among 2063 workers highly exposed to styrene and fibreglass (n = 39, WA SMR 2.37, CI 1.69-3.25). Results were similar using U.S. mortality rates. Workers employed for less than one year had statistically significant increased mortality from several lifestyle-related outcomes (alcoholism, ischaemic heart disease, cirrhosis, accidental poisoning and homicide). Conclusions The excess COPD mortality in this cohort is difficult to interpret. Recent reports associate styrene/fibreglass reinforced plastic manufacturing with another respiratory diseasebronchiolitis obliterans. Based on a review of COPD death certificates, bronchiolitis obliterans does not appear to be a contributing factor for excess COPD mortality. The COPD excess in this study points to a need for an in-depth investigation of respiratory disease and occupational styrene exposure. Short term worker results are consistent with other occupational cohort studies. Objectives We investigated associations between nursing occupational exposures and menstrual cycle regularity and cycle length. 0119Method Cross-sectional data were collected in 2010-2012 from 6309 nurses aged 21 to 45 from the Nurses' Health Study 3. We used multivariable regression modelling to analyse the associations between occupational exposures and prevalence of irregular cycles and long and short cycle lengths. Results Cycle length was recorded as <21 days (1.5%), 21-25 days (15.6%), 26-31 days (69.7%), and 32-50 days (13.2%). In additio...
