B: Component Exposure Limits
ACGIH, OSHA, NIOSH, EPA, Alberta, and Ontario exposure limit lists have been checked for
major components listed with CAS registry numbers. Other exposure limits may apply, check
with proper authorities.
Note: The Vacated OSHA permissible Exposure Limits (PELs) are those provided in the 1989
update to OSHA’s Air Contaminants Standard 29 CFR 1910.1000. These limits were vacated by
the U.S. Court of Appeals, Eleventh Circuit buy may be enforceable in some states.
Polyethylene (Ethene homopolymer) (9002-88-4)
ACGIH: 10 mg/m3 TWA (inhalable particles, recommended); 3 mg/m3 TWA (respirable
particles, recommended) (related to particulates (insoluble or poorly soluble)
not otherwise specified (PNOS))
OSHA (Vacated)*: 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction) (related to
particulates no otherwise related)
OSHA (Final): 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction) (related to
particulates no otherwise related)
Alberta: 10 mg/m3 TWA (total particulate); 3 mg/m3 TWAEV (respirable particulate)
(related to Particulate Not Otherwise Regulated)
Ontario: 10 mg/m3 TWAEV (inhalable); 3 mg/m3 TWAEV (respirable) (related to
Particles (insoluble or poorly soluble) Not Otherwise Specified (PNOS))
Talc (Hydrated Magnesium Silicate) (14807-96-6
ACGIH: 2 mg/m3 TWA (respirable fraction, particulate matter containing no asbestos
and < 1% crystalline silica)
OSHA (Vacated)*: 2 mg/m3 TWA (respirable dust, less than 1% crystalline silica)
NIOSH: 2 mg/m3 TWA (respirable dust, containing no asbestos and less than 1%
quartz)
1000 mg/m3 IDLH (containing no asbestos fibers, respirable particulate)
Alberta: 2 mg/m3 TWA (containing no asbestos fibers, respirable particulate)
Ontario: 2 mg/m3 TWAEV (containing no asbestos fibers, respirable) (particulate matter
containing no asbestos and less than 1% crystalline silica)
ENGINEERING CONTROLS
Engineering methods to reduce hazardous exposure are preferred controls. Methods include
mechanical ventilation (dilution and local exhaust) process or personal enclosure, remote and
automated operation, control of process conditions, leak detection and repair systems, and
other process modifications. Ensure all exhaust ventilation systems are discharged to outdoors,
away from air intakes and ignition sources. Supply sufficient replacement air to make up for air
removed by exhaust systems. Administrative (procedure) controls and use of personal
protective equipment also be required.
PERSONAL PROTECTIVE EQUIPMENT
Personal Protective Equipment: Eyes/Face
Wear safety glasses during normal handling. Wear full-face shield during thermal processing if
contact with molten material is likely.
Personal protective Equipment: Skin/Hands/Feet
To avoid burns from contact with molten product, use thermal insulating gloves and other
protective clothing (such as long sleeved shirts and long pants). Safety footwear with good
traction is recommended to help prevent slipping.
