ciprocating sanders, equipped with High Velocity, Low Volume (HVLV) lo- cal exhaust ventilation as part of the tool’s design are recommended because they have been shown to be effective in reducing total dust concentrations dur- ing the sanding of body filling com- pounds. HVLV ventilated sanders have cut total dust concentrations to one- tenth the levels produced using unven- tilated sanders.
Make sure all tools
and equipment used for sanding have built in dust extraction.”
Increased cost of sanders equipped with HVLV ventilation is minor compared with non-ventilated sanders. The amount of air used in the ventilated systems is also rela- tively low. Use of ventilated sanders can be enhanced by making them convenient to use, for example by installing retractable, flexible hosing attached to a central vacu- um system. Although initial costs for this system including an air mover, air cleaners, and duct work can be substantial, the sys- tem will help eliminate expensive repaints, shorten clean up time, and extend sandpa- per life. Workers also prefer using these HVLV sanders that result in a cleaner shop.
Secondly, workers need to protect them- selves from hazardous filler dust particles by following these safety precautions:
• Wear a P2 dust mask or greater.
• Wear goggles to protect your eyes.
• Wear coveralls which can be removed and left in the shop – keep the dust off your clothing, car and home. Young children are more severely affected when exposed to
these hazardous materials.
• Remove your coveralls and gloves in the
shop when you finish sanding – before using the restroom and before going for coffee breaks or lunch.
• Leave coveralls in the shop – throw away or wash in a commercial laundry.
• Before eating remove dusty clothing, wash your hands, arms and face thor- oughly with soap and water.
• Use a vacuum cleaner instead of com- pressed air to blow dust off yourself – everyone in the shop won't have to breathe the dust.
• Avoid exposure during pregnancy.
