Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) Whenever any building or section thereof, other than fumigation vaults or chambers, are fumigated with a poisonous gas:
(1) All
cracks, holes, crevices, openings, and apertures in walls, floors, and ceilings
shall be sealed so as to confine the gas to the rooms being
fumigated.
(2) Doors and windows
shall be closed and sealed; and legible warning signs shall be posted at all
entrances or approaches. Signs shall state premises under fumigation and type
of gas used and shall not be removed till fumigation and ventilation are
complete.
(3) Employees releasing
poisonous gases for fumigation shall wear respiratory protection of a type
approved for use in the gas used.
(4) Fumigation of single rooms is forbidden
unless such room constitutes a wing, floor, or other detached or semi-detached
section of a building, or can be effectively sealed off from the remainder of
the building.
(5) When a part of a
building is to be fumigated, all adjoining rooms, including those above and
below, and all other parts of the building or of adjacent buildings into which
the gas may penetrate shall be vacated. Windows in such locations shall be open
during fumigation.
(6) After the
exposure is completed, premises shall be purged of fumigant and the air therein
shall be tested. Employees shall not be allowed to enter the premises, except
to make tests, until the concentration of fumigant is known to be safe.
Employees making tests shall wear respiratory protection approved for use in
the fumigant used.
(7) Purging or
ventilation shall be carried out in such a manner as not to endanger
employees.
(8) Where flammable
fumigants are used, no source of ignition shall be allowed in premises being
fumigated. When part of a building is being fumigated, no source of ignition
shall be allowed in the rooms being fumigated or in adjoining rooms including
those above and below, or in adjacent buildings into which gas may reasonably
be expected to penetrate.
