COATINGSPRO MARCH 2015 35 fume, mist, or vapor), project specif- cations and safety data sheets (SDS) should be consulted. To determine the concentration of atmospheric contaminants, possible approaches that can be used include: • Persona l air monitor ing. T his is considered the "gold " standard in the industr y. T his involves the use of instr umentation to eva luate the worker's ex posure to an airbor ne contaminant. Col lecting this data involves placing a sampling dev ice in the worker's breathing zone (on the f ront of the shou lder w ithin a 12-inch [31 cm] rad ius of the head). • Mathematical approaches. Where feasible, data on the physical and chemical properties of respiratory hazards, work area dimensions, air exchange rates, and contaminant release rates can be used to estimate the maximum exposure that could be anticipated at the jobsite. • Objective data. T his is used to demonstrate the highest exposures likely to occur under reasonably foreseeable conditions of use or handling. W here objective data is used, the data must have been obtained under conditions closely resembling the process, ty pes of materials, control methods, work practices, and environmental conditions that are expected to occur on the jobsite. Sources of objective data include, but are not limited to, industr y studies, studies performed by trade associ- ations, or tests conducted by chemical manufacturers. Te size and geometric confg- uration of the work area may afect the potential for accumulation of atmospheric contaminants. Hazard evaluations should also account for the nature of the work performed. For example, spray application can gener- ate mists and vapors whereas brush or roller will only generate vapors. Te amount of products to be used is another important consideration. Once the hazard evaluation is completed, the next step is to select the respiratory protection to be used. For example, the concentration must not exceed the Maximum Use Concentration of the respirator, which is determined by multiplying the Assigned Protection Factor of the respi- rator by the Permissible Exposure Limit (PEL) for that substance. OSHA, in paragraph (d)(3) of the Respiratory Protection Standard, specifes the Assigned Protection Factors for specifc types of respirators. Safety Watch when the going gets tough... we get tougher.
