Massachusetts contractors are avoiding the RRP requirement to become a Lead Safe Renovation Contractor (Certified Firm). The chief reason is the OSHA Lead in Construction requirements written into the Mass RRP Law 454 CMR 22.00. This OSHA Standard requires compliance with medical monitoring and respiratory protection provisions. Proof that contractors are avoiding the law is apparent in the number of firms on the Mass Lead Safe Renovation List. To date there after two years there are approximately 3100 Massachusetts companies who have applied for and received their license to legally work on pre-1978 properties in the state. In comparison as of July 2010 there are over 4000 Mass EPA Certified Firms. In our Lead in Construction Trainings workshops contractors are often unaware of the OSHA Standard that has been around for years.
