 1.2 PESTICIDES (WOOD PRESERVATIVES). Wood preservatives are
classified by the Federal Insecticide, Fungicide and Rodenticide Act
(FIFRA) as pesticides. Only Environmental Protection Agency (EPA)
registered materials are approved for use; all recommendations made are
based on this requirement. OPNAVINST 6250.4A requires that all pes-
ticide usage, contractor or in-house, be reported on NAVFACENGCOM
Form 6250/2 (in-door applications) or 6250/3 (out-door applications).
NOTE: It is important to remember -
only DoD or State (contractors)
certified pesticide applicators are
permitted to apply wood preservative
chemicals, termiticides, herbicides, or
conduct fumigation operations on Navy
activities.
Safety is always an important consideration when handling preservative-
treated wood. Users of preservative-treated wood should carefully follow
the safety precautions outlined in the Consumer Information Sheet (CIS)
and Safety Data Sheet (SDS) supplied by most pesticide formulators. For
additional information users should contact the cognizant EFD Applied
Biologist [See Appendix (A)] or local Industrial Hygenist.
Wood preservative chemicals bind tightly to the wood fibers and when
handled properly pose little health risk. Individuals should wear long sleeve
shirts, coveralls and chemical resistant work gloves when handling treated
wood products to avoid prolonged or repeated skin contact. When cutting,
drilling or machining treated wood products, a dust respirator should be
worn to avoid inhalation of sawdust. The amount of dust and associated
preservative chemical inhaled can be significant if an individual is not
properly protected.
1.3 SPECIAL PROBLEMS.
13.1 High-band Steel Support Sleeves. Recent CDAA surveys have
identified significant premature failures in high-band antennae poles at
several sites throughout the world. The predominance of failures can be
attributed to the metal support sleeves (Figure 1-1) and thereby creates an
extremely favorable environment for decay fungi to grow, i.e., the ac-
cumulation and retention of water. In many instances failures are occurring
in less than half the projected service life. Corrective actions include: 1)
providing 3/4 inch diameter drain holes at the base of each support sleeve
