title: Assessment of the living and workplace health and safety conditions of site-resident construction workers in Tehran, Iran.
abstract: OBJECTIVE
  The purpose of this study was to assess living and workplace safety conditions of construction workers in Tehran, Iran.
  
  
  METHODS
  This cross-sectional study was conducted among 410 construction sites in a municipal area of Tehran whose municipal building permits were issued in 2011. Data on ventilation, workplace safety and hygiene were collected by direct observation and interviews with site foremen. Noise levels were estimated from 10 sound-level-meter stations in the municipality area.
  
  
  RESULTS
  Lack of ventilation in the workers' rooms was abundant. Bathrooms were unhygienic and minimum requirements such as lighting and ventilation did not exist in 80% of the cases. In nearly 50% of large construction sites, sewage and garbage disposal were inappropriate. Elevator safety was poor at all sites and no measures for fall prevention were present in over 88% of active construction sites. This study showed that the mean 24-h equivalent continuous sound level Leq was over 70 dB in 80% of the sites during weekdays.
  
  
  CONCLUSIONS
  The results of this study revealed poor health and safety living and working conditions of construction workers in Tehran.
