Exposure Controls - Engineering Measures/Controls
• Keep exposures to dust generated from cutting, drilling, routing, sawing or crushing, as low as possible.
• Perform cutting of boards in a well-ventilated area (outside) and use local exhaust ventilation to keep exposures
below the recommended exposure limits.
• When using power saws, use blades designed for fiber cement siding.
• Use circular saws with a built-in dust collection container or shroud that functions as a hood, partially encloses the
saw blade, that is connected to the local area ventilation system (such as shop vacuum).
• Use a shop vacuum having a filter with 99% or greater efficiency (HEPA recommended), with an air-flow rate as
specified by the saw manufacturer.
• Use of high efficiency disposable filter bags is recommended as a pre-filter in the shop vacuum to capture most of the
dust. This will prolong the life of the cartridge filter and contain the dust to reduce exposure during disposal.
Personal Protective Equipment
Respiratory • If exposure controls listed above are not implemented, use NIOSH N-95 respirators when cutting, drilling,
sanding,etc.
Eyes/Face/Hands • Safety glasses with side shields should be worn at a minimum.
Skin/Body • Normal work clothing (long sleeved shirts and long pants) is recommended.
