Visual recording of testing is critical because it will assist in tracing the source of an anomaly in the results. For example, video may reveal wheth- er operator error or an equipment mal- function occurred. Arrange the equipment testing facili- ty to replicate as much of the process train as possible. The test location should be a dedicated area with re- stricted access. You should quarantine the facility from the beginning of the pretest cleaning. The vendor should state procedures that it undertook to ensure that no surrogate contamina- tion took place prior to the test. Data recording and reporting Be as detailed as possible when record- ing and reporting data to make your evaluation and analysis as accurate as possible and to alert you to trends or inconsistencies. If the data analysis indicates successful results, be sure to document the process so you can re- peat the procedures when training per- sonnel on the containment equipment. Include the following elements in your reporting: • Equipment. Describe all details of the equipment, including mon- itors, air sampling pumps, and type of surface swab; facility; and system and control conditions. • Surrogate-material details. The mate- rial safety data sheet (MSDS) usually can provide this information. • Frequency and duration of sam- pling. Include the area tested and personnel involved. • Sampler types and locations. De- tail the positioning of all airborne particle samplers relative to the test unit; the dimensions of the test facility; and the directions of any conditioning airflows. • HVAC inlets and outlets. Note the position of swab samples for sur- face contamination on a sketch or with a photograph of the test unit. • Airborne concentration data with method used. Use continuous monitoring with instantaneous readout or time-weighted-average sampling, with off-line analysis. • Filter sample exposure data. Express this data as a maximum airborne concentration that will be adequate to calculate an equiva- lent time weighted exposure limit based on anticipated operating cycles. • Surface concentration data. Include details about sampling locations and collection methods, conditions of equipment surfaces, and the location of and method for dust storage. • Interpretation of results and conclusions. Include the reasoning behind the summary conclusions and a statement of limitations with the data. The testing team will base this analysis on the testing proto- col created prior to conducting the test. • Digital video recording. Capture the entire length of the testing process to catch every potential issue or event outside of protocol. Include application and removal of samples and all operations that the operator carried out. You can use digital photographs to supplement the recording process. Make sure to include these elements in your testing protocol and reporting. See the Case Study, Click Here
