The Federal EPA requires that commercial/residential painting contractors be certified to prepare surfaces containing lead based paint on residential and public structures. As a result, when respirators equipped with HEPA filtration are required to be worn to reduce worker exposure levels to below the permissible exposure limit for lead, the surface preparation work is often subcontracted to a licensed lead abate contractor who holds these types of certifications.
The Federal EPA requires that commercial/residential painting contractors be certified to prepare surfaces containing lead based paint on residential and public structures. As a result, when respirators equipped with HEPA filtration are required to be worn to reduce worker exposure levels to below the permissible exposure limit for lead, the surface preparation work is often subcontracted to a licensed lead abate contractor who holds these types of certifications. Unfortunately, there have been several coating failures on commercial/residential buildings, originally containing lead paint that were the result of surface preparation performed by a lead abatement contractor and painting performed by a commercial painting contractor. These failures are generally catastrophic; with large sheets of paint delaminating from the building façade shortly after application. This paper discusses the applicable regulations that govern lead paint removal, provides insight into the reasons that painting contractors use lead abatement contractors for surface preparation work, and highlights the potential consequences of these partnerships. By bringing these issues to the forefront, painting contractors can realize the value of becoming licensed to perform surface preparation operations on their own, rather than leaving it in the hands of a contractor unfamiliar with its inherent importance. In this manner, safety can be preserved without sacrificing quality. The paper also discusses various surface preparation methods (e.g., chemical stripping, power tools with vacuum shrouds) that can be employed, as engineering controls, to reduce the inherent hazards of lead paint disturbing operations. Recommended practices and controls that can be implemented in the event that a lead abatement contractor must perform surface preparation operations for the painting contractor are also discussed.
Often when a polymeric flooring system fails, the cause of the problem is unknown. Forensic testing is used to determine the cause of failure while eliminating other potential causes. A basic understanding of the approach to a forensic investigation and the types of testing used will help aid in correcting the problem so future failures and project costs are reduced.

The Occupational Safety and Health Administration (OSHA) defines abrasive blasting as “using compressed air or water to direct a high-velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture or prepare a surface for the application of paint or other type of coating.” OSHA regulations governing General Industry, Construction, and Shipyards mandate the use of abrasive-blast respirators approved by the National Institute for Occupational Safety and Health (NIOSH). Blast respirators are Type-CE supplied-air respirators, commonly known as “blast helmets.” This article will review and explain the components and the requirements pertaining to the use of these respirators.
The use of fall protection equipment is very common nowadays. Still, however, many users do not know the basics of fall protection or the why and how this equipment function. Safety in general depends a lot on the use of common sense and proper due diligence. Understanding the risk of falling will lead us to be safe. It is a fact that we are all exposed to Gravity at all times 24/7; and we, humans in general, take little or no protection and precaution against gravity. The reality is that falls are never expected.
