On May 8 and 9, 2006, Dr. Henry P. Shotwell, Ph.D., CIH, Senior Vice President, and Mr. Adam J. Pratt, Manager of Technical Services, both of Atlantic Environmental, Inc. (AEI) performed an Industrial Hygiene Survey for respirable dust, respirable fibers, total dust and free silica at the Tapeta™ Footings facility located at 102 Piney Creek Lane in North East, Maryland.
Samples for respirable fibers, respirable dust, and total dust and free silica were collected on the Tapeta™ Footings racetrack; and samples for respirable dust, which were also analyzed for silica, were also collected at a nearby standard dirt/sand racetrack for comparison purposes.
All respirable fiber samples were less than the laboratory limit of detection.
With the exception of one sample taken on the dirt/sand track, each respirable dust sample was less than the laboratory limit of detection. The sample taken on the dirt/sand track was less than the Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL) for respirable dust.
With the exception of one sample, each total dust and free silica sample was less than the laboratory limit of detection. The sample which was above the limit of detection had total dust and quartz concentrations below the OSHA PEL for each material.
The analytical results of the samples collected at Tapeta™ Farm and the standard dirt/sand track indicate that a horse and rider have a greater risk of exposure to respirable dust on a standard dirt/sand track than on a track covered with Tapeta™ Footings material. Based on these results, AEI is of the opinion that no corrective actions or modifications are necessary at this time.
