Improper sealing can cause reduction in performance of respirators to protect health and safety of workers against risks related to chemical agents at work. This study is aimed to evaluate the fitness of half-face respirators and other related factors on it in an Iranian petrochemical industry.
Methods: In this cross sectional study 54 persons using half mask in a petrochemical complex were evaluated qualitatively by means of Moldex Kit. The effect of staff training on adjusting and doing seal-check and effects of facial hair and different mask's brand used in the industry on respirator fit was investigated. The data were analyzed using Chi-square and McNemar tests by means of SPSS software.
Results: Before intervention 17 (31.5%) of staff out of 54 passed the test. After training the results improved from 31.5% to 92.6% (P
