8. EXPOSURE CONTROLS - PERSONAL PROTECTION (Continued)
PROTECTIVE EQUIPMENT (continued):
RESPIRATORY PROTECTION: Maintain airborne contaminant concentrations below exposure limits listed above. For materials
without listed exposure limits, minimize respiratory exposure. If necessary, use only respiratory protection authorized under appropriate
regulations. Oxygen levels below 19.5% are considered IDLH by U.S. OSHA. In such atmospheres, use of a full-facepiece
pressure/demand SCBA or a full facepiece, supplied air respirator with auxiliary self-contained air supply is required under U.S.
OSHA‟s Respiratory Protection Standard (1910.134-1998). The following are NIOSH Respiratory Protection Equipment Guidelines for
some components of these products:
CARBON BLACK
CONCENTRATION RESPIRATORY PROTECTION
Up to 17.5 mg/m3: Any Dust and Mist Respirator.
Up to 35 mg/m3: Any Dust and Mist Respirator except single-use and quarter-mask respirators, or any Supplied-Air Respirator (SAR).
Up to 87.5 mg/m3: Any SAR operated in a continuous-flow mode, or any Powered, Air-Purifying Respirator (PAPR) with a dust and mist filter.
Up to 175 mg/m3: Any Air-Purifying, Full-Facepiece Respirator with a high-efficiency particulate filter, or any PAPR with a tight-fitting facepiece and a
high-efficiency particulate filter, or any Self-Contained Breathing Apparatus (SCBA) with a full facepiece, or any SAR with a full
facepiece.
Up to 1750 mg/m3: Any SAR operated in a pressure-demand or other positive-pressure mode.
Emergency or Planned Entry into Unknown Concentrations or IDLH Conditions: Any SCBA that has a full facepiece and is operated in a pressure-demand or
other positive-pressure mode, or any SAR that has a full facepiece and is operated in a pressure-demand or other positive-pressure
mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure
mode.
Escape: Any Air-Purifying, Full-Facepiece Respirator with a high-efficiency particulate filter, or any appropriate escape-type, SCBA.
In Presence of Polycyclicaromatic Hydrocarbons:
Based on NIOSH REL at Concentrations Above the NIOSH REL, or Where There is No REL, at Any Detectable Concentration: Any SCBA that has a full
facepiece and is operated in a pressure-demand or other positive-pressure mode, or any SAR that has a full facepiece and is operated
in a pressure-demand or other positive-pressure mode in combination with an auxiliary SCBA operated in pressure-demand or other
positive-pressure mode.
Escape: Any Air-Purifying, Full-Facepiece Respirator with a high-efficiency particulate filter, or any appropriate escape-type, SCBA.
CRYSTALLINE SILICA
CONCENTRATION RESPIRATORY PROTECTION
Up to 0.5 mg/m
3
: Any Air-Purifying Respirator with a high-efficiency particulate filter.
Up to 1.25 mg/m
3
: Any Powered, Air-Purifying Respirator (PAPR) with a high-efficiency particulate filter, or any Supplied-Air Respirator (SAR) operated in
a continuous-flow mode.
Up to 2.5 mg/m
3
: Any Air-Purifying, Full-Facepiece Respirator with a high-efficiency particulate filter, or any PAPR with a tight-fitting facepiece and a
high-efficiency particulate filter.
Up to 25 mg/m
3
: Any SAR operated in a pressure-demand or other positive-pressure mode.
Emergency or Planned Entry into Unknown Concentrations or IDLH Conditions: Any SCBA that has a full facepiece and is operated in a pressure-demand or
other positive-pressure mode, or any SAR that has a full facepiece and is operated in a pressure-demand or other positive-pressure
mode in combination with an auxiliary SCBA operated in pressure-demand or other positive-pressure mode.
Escape: Any Air-Purifying, Full-Facepiece Respirator with a high-efficiency particulate filter, or any appropriate escape-type, SCBA.
EYE PROTECTION: Wear safety goggles/glasses as appropriate for the task if dust or other particulates are present. Face shields are
recommended if solutions are made. If necessary, refer to appropriate regulations.
HAND PROTECTION: Wash hands and wrists before putting on and after removing gloves. None needed under normal conditions of
use and handling. Wear appropriate glove for work being done. Resistance of specific materials can vary from product to product.
Evaluate resistance under conditions of use and maintain gloves carefully. Because all gloves are to some extent permeable and
their permeability increases with time, they should be changed regularly or immediately if torn or punctured. Use triple gloves for spill
response, as stated in Section 6 (Accidental Release Measures) of this SDS. If necessary refer to appropriate regulations.
SKIN PROTECTION: Use appropriate protective clothing for the task. Full-body chemical protective clothing is recommended for
emergency response procedures. If a hazard of injury to the feet exists due to falling objects, rolling objects, where objects may pierce
the soles of the feet or where employee‟s feet may be exposed to electrical hazards, use foot protection, as described in appropriate
regulations. If necessary, refer to the U.S. OSHA Technical Manual (Section VII: Personal Protective Equipment) or other
appropriate regulations.
