![]() The inspection should evaluate the type of structure, floor layout, physical conditions, and airflows of the building(s) being studied. GUIDANCEĪ pre-sampling inspection should be performed prior to each sampling event to identify conditions that may affect or interfere with the proposed testing. The steps discussed include pre-sampling inspection and preparation of buildings, product inventories, and the collection and analysis of samples. This document provides guidance for preparing sampling locations and collecting samples for laboratory analysis to ensure the integrity of the test results and allow for meaningful interpretation of the data. The purpose of this document is to outline the recommended procedure for testing indoor air for volatile chemicals. Study of Volatile Organic Chemicals in Air of Fuel Oil Heated Homes, a tabulated summary of concentrations for 69 volatile organic chemicals in indoor and outdoor air of fuel oil heated homes, is also available.Īir testing for specific chemical compounds is an investigative tool used to characterize the nature and extent of contaminants in air and to determine whether contaminant sources affect indoor air quality.Indoor Air Sampling and Analysis Guidance is available in Portable Document Format (PDF, 31KB, 8pg.).Indoor Air Sampling and Analysis Guidance All Health Care Professionals & Patient Safety.Clinical Guidelines, Standards & Quality of Care.Health & Safety in the Home, Workplace & Outdoors.Birth, Death, Marriage & Divorce Records. ![]() Symptoms were inconsistently related to dust concentrations in the personal breathing zone. Conclusions-The FEV1 and FVC were impaired in smokers and those exposed to high dust concentrations in the personal breathing zone. On regression analysis, impairment of ventilatory function (FEV1, FVC) was predicted by smoking, male sex, age, not working in the weaving shed, not being white, and personal dust concentrations. Non-specific chest tightness was predicted by low dust concentrations and persistent cough by high dust concentrations. There was a strong correlation (r=0.94, p<0.0001) between pd1 and pd2. The corresponding value for total dust with large fibres lifted off the filter paper (pd2) was 1.55 mg/m3. Mean total dust concentration (pd1) in the personal breathing zone was 1.98 mg/m3. Results-The FEV1 and FVC were reduced in workers with respiratory symptoms (non-specific chest tightness, shortness of breath, persistent cough, and wheezing) as well as in preparation room workers, current and former smokers, Asians, those working with predominantly cotton fibre (>50% cotton) and starch size. Dust concentrations and ventilatory tests were analysed statistically with the Student's t test, Pearson's correlation coefficient, and forward step regression for relations with symptoms and environmental factors. A representative sample of workers from each occupational group underwent dust sampling in their personal breathing zone. ![]() Ventilatory function tests, forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) were performed on each person. Methods-Each person was given a respiratory symptom questionnaire (modified Medical Research Council, UK, questionnaire on respiratory diseases). However, this occupational group has not been extensively studied. Weaving room dust is considered to be less harmful than that encountered in the cardroom or spinning room and weavers are generally thought to have less respiratory disability than carders or spinners. Background-To report findings on ventilatory function and estimations of concentrations of personal breathing zone dust in Lancashire textile weavers.
