Spray foam contractors are encouraged
to ventilate the area during and following
spraying. For example, windows on opposite
sides of a room or structure could be opened
to allow outdoor air to enter and inside air to
escape. Of course, weather conditions and the
circumstances of the job site (e.g., proximity
to bystanders/passersby, other buildings,
vehicles, possible regulations, etc.) must be
taken into consideration. Active ventilation (i.e.,
fan/blower exhausting to outside of building)
may also be used. Access should be restricted
near the exhaust point(s). Do not locate exhaust
points near air intakes.
Air monitoring studies have shown that low
levels of airborne A- and B-side chemicals can
be present in the truck trailer. Accordingly, it is
prudent to ensure that all drums of chemicals
are tightly closed, connections between pumps,
drums, hoses, etc. are tight, and that any drips/
leaks are promptly addressed.
Eating, drinking, smoking, and chewing
tobacco or gum should not be conducted in
the truck trailer or active work area due to the
presence of chemicals. Further, employees
should wash their hands well with soap and
water after handling any chemicals.
