Respiratory protection is required for the
spray foam applicator and any other SPF
contractor employees working in the same
area (e.g., on the same floor) as the applicator
during spraying, as well as during post-spray
activities (e.g., trimming foam, clean-up) in
the application area.
The recommended type of NIOSH-approved
respiratory protection is a full face or hoodtype supplied air respirator operated in positive
pressure or continuous flow mode. 4
Liquid Chemical Handling
When handling liquid product that has
been heated, an air purifying respirator with
combination organic vapor/particulate (P100)
cartridges is recommended. Per OSHA’s
respiratory protection standard (29 CFR
1910.134), the cartridges must be equipped with
end-of-service life indicators (ESLI) certified by
NIOSH; otherwise, a change out schedule must
be developed and implemented. The basis for
the change out schedule must be described in a
written respiratory protection program (29 CFR
1910.134(d)(3)(iii)). The change-out schedule is
based on the capacity of the cartridges relative
to workplace airborne concentrations. If the
wearer notices odors, irritation, or breathing
resistance at any time, cartridges should be
changed promptly.
General
Per OSHA’s Respiratory Protection Standard,
a medical evaluation is required prior to use
to determine the wearer’s fitness for using
a respirator (29 CFR 1910.134(e)). Users of
respirators with tight-fitting face pieces must
pass an annual fit test on the same make,
model, and size of respirator that they use
to ensure a proper fit (29 CFR 1910.134(f)).
Respirator users must not have facial hair that
interferes with the face piece seal or inhalation/
exhalation valves (29 CFR 1910.134(g)(1)).
Respirators should be regularly cleaned and
disinfected according to the manufacturer’s
instructions and must be periodically inspected
for damage and deterioration. Deteriorated/
defective respirators should be taken out of
service (29 CFR 1910.134(h)).
