F -- CONTAINMENT EFFICIENCY: ENVIRONMENT AND WORKER EXPOSURE SOL DTFH61-95-R-00114 DUE 062395 POC Lorraine Johnson, Contract Specialist, HCP-40E, (202) 366-0337. The objective of this requirement is to evaluate representative lead paint removal abrasive blasting containment operations to determine their ability to protect the environment and the worker from lead exposure. The work shall include development of a field containment evaluation and monitoring plan for each of the four research study areas discussed below, address and resolve the associated questions, and require data acquisition at field sites and development of implementation recommendations. The four research areas and questions follow. 1. Evaluate representative field abrasive blasting containment systems for conformance with OSHA lead removal regulations and their efficiencies in protecting the environment during operations. QUESTION: Can lead paint abrasive blasting paint removal operations that comply with OSHA's Lead in Construction Regulations adequately protect the work site environment? 2. Monitor containment air flow, worker exposure inside of hood, dust concentrations within containment, industrial hygiene practices, and the resultant worker's lead blood level. QUESTION: Can operational control regimens and environmental dust monitoring protocols other than continuous monitoring can be used to insure protection of the environment? 3. Evaluate nonabrasive blast operations i.e., power tool cleaning, hand tool cleaning, torch cutting for lead generation in the environment and identify cost effective control options for these operations. QUESTION: How much lead and dust concentration is generated by power tool cleaning, hand tool cleaning, and torch cutting, and what are the most cost effective containment and worker protection methods are? 4. Recommend cost effective environmental monitoring protocols and evaluate the operational safety factors for type CE air fed hoods and determine if their use is in compliance with Lead in Construction protocols and sufficiently protect the workers from lead exposure in achievable containment air flows. QUESTION: Is the use of type CE air fed hoods in conjuction with containment ventilation and compliance with OSHA's Lead in Construction protocols sufficient to protect the worker from elevated lead blood levels, and are hoods with a greater safety factor required to achieve this? All requests for this solicitation must be in writing. Furnish two self-adressed gummed labels for each solicitation requested. The solicitation number should appear on the bottom edge of the labels.
