Oil Residue on Metals

Expanded metal lath and other metal goods are often shipped to sites coated in rancid oil residues left over from the manufacturing process. Such residues will be odorous for a prolonged period of time unless the metal is cleaned. When these oils are left in metal duct­work, hot air blown through the ductwork distributes these odors throughout the house. To avoid this unwanted pollution source, con­sider adding the following to your specifica­tions:

• Remove oil residue from all coated metal products using a high-pressure hose and one of the acceptable cleaning products listed in these specifications.

Some builders have found that the high-pres­sure hoses at self-service car washes are effec­tive for removing oil residues.

Metals and Conductivity

The role that metals play in the electrodimate of a building, along with proper grounding considerations, will be discussed in Division 16.

Metal Termite Shielding

Where floors are joisted, the proper applica­tion of metal termite shielding, as illustrated, will create a physical barrier that is effective against subterranean termites.
