On October 6, 2006, NIOSH released a new CBRN standard
for powered air-purifying respirators (PAPRs)
MSA has partnered with Safety Tech to provide a system
that passes the performance requirements of the new
standard
Tight-fitting facepiece PAPRs are designed for First
Responders
Loose-fitting facepiece PAPRs are designed for First
Receivers
The Responder CBRN PAPR is MSA’s answer to the
standard
The Responder CBRN PAPR is the first CBRN PAPR with
tight-fitting facepiece to be approved by NIOSH
Background
Responder CBRN PAPR provides
non-IDLH protection for extended
periods of time for:
 First Responders
 Military Personnel
 Special Operations Personnel
Background
Three Components

C420 Blower
 Purchased from Safety Tech
 Same blower used by Safety Tech, Dräger, & Scott
 Over 50,000 fielded in the Apache Helicopter program,
U.S. Special Forces, Federal tactical units, and U.S. and
U.K. Army NBC patient chemical casualty wrap programs

Facepieces
 Millennium® Facepiece
 Ultra Elite® Facepiece

Cartridges
 Responder CBRN Cartridge
 OptiFilter® XL Cartridge
 GME Multigas HE Cartridge
C420 PAPR
 A belt-mounted powered airpurifying respirator that forces
ambient air through filters to the
facepiece
 The motor-blower provides
constant air flow of at least 115 lpm
to the facepiece via the breathing
tube
 Reduces fatigue by virtually
eliminating breathing resistance
 Ideal for extended wear times
C420 PAPR
 Creates a cooling effect that
eliminates facepiece fogging and
keeps the user more comfortable
 Continuous air flow creates a slight
positive pressure
 EMI-shielded to MIL-STD-461C,
so it won’t interfere with radio
communications
 PAPRs offer an OSHA-assigned
protection factor 20 times greater
than APRs
C420 PAPR
Basic kit includes:

Commercial version of MCU-2/P
(developed for Air Force during
Operation Desert Storm)
Same facepiece as CBRN gas mask, so
no need for multiple fit tests
Nose cup has 2 check valves to improve
air flow, minimize lens fogging
Six-point head harness maximizes
comfort, improves ease of donning
Drinking tube allows wearer to ingest
water without removing mask
Facepieces
Ultra Elite

Soft Hycar rubber
Available with 5-point rubber or
SpeeD-ON® head harness
Optional ClearCommand®
Amplifier for increased
communication capabilities
Cartridges
Responder Cartridge
 NIOSH-approved for CBRN PAPR
 CBRN-approved for both APR and PAPR
 Provides longer service life for ammonia, formaldehyde,
and acid gases than GME Cartridge
Cartridges
OptiFilter® XL HE
 Type H filter—a HEPA, P100 particulate
filter (99.97% efficient against all aerosols,
oily and non-oily)
 Effective against particulates (dusts and
mists) but not poison gases or vapors
 Filter efficiency improves with use, but
users probably need to change filters
when pressure drop gets too high for
blower to operate effectively
 Choose for dust-filled environments
Cartridges
PAPR GME Multigas HE
 A combination cartridge comprised of P100 filter
and activated carbon bed to absorb poison gases
and vapors
 Filters out a broad spectrum of agents, such as:
acid gases (including chlorine, sulfur dioxide, and
chlorine dioxide), ammonia, formaldehyde, and
organic vapors
 Carbon bed lasts only as long as carbon is not
saturated with chemical, so GME has a limited
service life
 Service life is a function of the challenge agent
concentration and flow rate plus environmental
factors (humidity and temperature)
 Cartridge to choose for OSHA-regulated chemicals
with concentrations >TLV
Options
Facepiece:

Ultra Elite® or Millennium® (plus accessories)
Battery:
 Lithium-based
single-use mission battery
 Up to 8 hours of run time
 Nickel-based
rechargeable battery
 Up to 4 hours of run time
Breathing tube:
 36”
instead of standard 30”
