Answer these questions please:
Haz Mat Data: Lead, cadmium, and chromium metals and o,m,p-xylene (mix), stoddard solvent, isopropanol, and 2-butanone (methyl ethyl ketone or MEK) solvents are common raw materials used in the oil-based paint manufacturing process. Use MSDSs or the NIOSH Pocket Guide to complete the table. If you do not find info, then simply leave cell in table blank.

1. Are you concerned about contamination of the building and overall site? If yes, what type(s) of chemical contaminants?
2. Are you concerned about any biological hazards? If yes, what type(s) and sources?
3. Are you concerned about any radiological hazards? If yes, what type(s) and sources?
4. Are you concerned about the piping insulation? If yes, why?
5. During initial site entry and characterization, what is the minimum PPE (specify level and components) you would recommend?
6. Are you concerned about the pipes themselves? (Hint: Some pipes served as conduit to transfer raw materials and products. Eventually, as part of remediation, the pipes will need to be cut and removed).
7. During initial site entry and characterization, what major instantaneous ("real time") air monitoring equipment and SOPs (i.e., strategy; "caution" and "back-out" levels; etc.) would you recommend for use?
8. During opening of containers and/or cutting pipes containing liquids solvents, what major instantaneous air monitoring equipment would you recommend for use?
9. Would you recommend conducting any instantaneous air monitoring during any ongoing site activities (e.g., remediation)? If so, what would you recommend?
10. Would you recommend any integrated ("continuous") air monitoring during any ongoing site activities (e.g., remediation)? If so, what would you recommend?
11. Would you recommend collection of any bulk/grab samples? If so, what would you recommend?
