Rust and Corrosion. Check hypochlorination unit for rust and corrosion. If any bare metal or
corrosion exists, clean, and apply thin coat of oil Report it to your supervisor.
(3) Bolt, Nuts, and Screws. Check all for obvious looseness, missing, bent, or broken condition You
can't try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads If you
find a bolt, nut, or screw you think is loose, tighten it or report it to your supervisor.
(4)
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a
bad weld, report it to your supervisor.

Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings are
tight. Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If leak
comes from loose fitting of connector, tighten It If something is broken or worn out, report it to your
supervisor
