Respirable Dust
Engineering Controls
 Work/Hygiene Practices: The score and snap method of cutting is recommended. Sawing, drilling or
machining will produce dust.
 Ventilation: Provide local and general exhaust ventilation to maintain a dust level below the PEL/TLV.
 Utilize wet methods, when appropriate, to reduce generation of dust.
Personal Protective Equipment
 Respiratory Protection: A NIOSH approved particulate respirator is recommended in poorly ventilated
areas or if the PEL/TLV is exceeded. OSHA's 29 CFR 1910.134 (Respiratory Protection Standard)
must be followed whenever work conditions require respirator use.
 Eye Protection: Safety glasses or goggles.
 Skin: Gloves, protective clothing and/or barrier creams may be utilized if conditions warrant.
