Predicting exposure to jobsite hazards and implementing effective controls to protect workers has historically been a challenge in the construction industry. To address this need, CPWR-The Center for Construction Research and Training has developed the Exposure Control Database (ECD) for four major hazards: silica, welding fumes, noise, and lead.

The ECD has been populated with objective exposure measurements, and enables users to predict exposure to hazards before they start work. All data comes from reliable sources such as peer-reviewed literature and government reports. The database is intended to drive the use of effective engineering controls and sufficiently protective personal protective equipment (PPE). The ECD is constantly growing. So, if you do not find the information you need, please check back soon.

It must be noted that the ECD cannot be used for regulatory compliance purposes, and it does not replace the judgement of an Industrial Hygienist or other health and safety professional.
