(a) Scope. These general work practices are minimum
requirements and do not constitute complete or sufficient specifications
for a mold remediation project. More detailed requirements developed
by an assessment consultant for a particular project shall take precedence
over the provisions of this section.
(b) Remediation work plan. A remediation contractor
shall prepare a mold remediation work plan that is specific to each
project, fulfills all the requirements of the mold remediation protocol,
and provides specific instructions and/or standard operating procedures
for how a mold remediation project will be performed.
(c) On-site records. A licensed mold remediation company
and a licensed mold remediation contractor who is not employed by
a company shall maintain the following records and documents on-site
at the location of the mold-related activities at a project for its
duration:
(1) a current copy of the mold remediation work plan
and all mold remediation protocols used in the preparation of the
work plan; and
(2) a listing of the names and license or registration
numbers of all individuals working on the remediation project.
(d) Personal protective equipment (PPE) requirements.
If an assessment consultant specifies in the mold remediation protocol
that PPE is required for the project, the remediation contractor or
company shall provide the specified PPE to all individuals who engage
in remediation activities and who will, or are anticipated to, disturb
or remove mold contamination, when the mold affects a total surface
area for the project of 25 contiguous square feet or more. The recommended
minimum PPE is an N-95 respirator.
(1) Each individual who is provided PPE must receive
training on the appropriate use and care of the provided PPE.
(2) The remediation contractor or company must document
successful completion of the training before the individual performs
regulated activities.
(e) Containment requirements. The containment specified
in the remediation protocol must be used on a mold remediation project
when the mold affects a total surface area of 25 contiguous square
feet or more for the project.
(1) Containment is not required if only persons who
are licensed or registered under this chapter occupy the building
in which the remediation takes place at any time between the start-date
and stop-date for the project as specified on the notification required
under §78.110.
(2) The containment, when constructed as described
in the remediation work plan and under normal conditions of use, must
prevent the spread of mold to areas outside the containment.
(3) If walk-in containment is used, supply and return
air vents must be blocked and air pressure within the walk-in containment
must be lower than the pressure in building areas adjacent to the
containment.
(A) Operation of equipment to recirculate air inside
of containment without maintaining negative air pressure may be conducted
when the specific conditions, phases, and time periods during which
it may or must occur are specified in the mold remediation protocol
before commencing this use of equipment.
(B) Operation of equipment to recirculate air inside
of containment without maintaining negative air pressure is prohibited
during periods of active mold remediation activity.
(4) The mold remediation contractor shall ensure that
the containment is maintained in accordance with the work plan and
the requirements of this chapter until the containment is removed.
(f) Notice signs. Signs advising that a mold remediation
project is in progress shall be displayed at all accessible entrances
to remediation areas.
(1) Notice signs shall be at least eight (8) inches
by ten (10) inches in size and shall bear the words "NOTICE: Mold
remediation project in progress" in black on a yellow background.
The text of the signs must be legible from a distance of ten (10)
feet.
(2) Notice signs must be displayed continuously during
the period in which active mold
remediation is ongoing.
(g) Removal of containment. No person shall remove
or dismantle any walk-in containment structures or materials from
a project site before receipt by the licensed mold remediation contractor
or remediation company overseeing the project of a written notice
from a licensed mold assessment consultant that the project has achieved
clearance as described under §78.140.
(h) Disinfectants, biocides, and antimicrobial coatings.
(1) A disinfectant, biocide, or antimicrobial coating
may be used only if:
(A) its use is specified in a mold remediation protocol;
(B) it is registered by the United States Environmental
Protection Agency (EPA) for the intended use; and
(C) the use is consistent with the manufacturer's labeling
instructions.
(2) If a protocol specifies the use of a disinfectant,
biocide, or antimicrobial coating but does not specify the brand or
type of product, a remediation contractor may select the brand or
type of product to be used, subject to the other provisions of this
subsection. A decision by an assessment consultant or remediation
contractor to use such a product must take into account the potential
for occupant sensitivities and possible adverse reactions to chemicals
that have the potential to be off-gassed from surfaces coated with
the product.
(3) A person who applies a biocide to wood to control
a wood-infesting organism must be licensed by the Structural Pest
Control Service of the Texas Department of Agriculture as provided
under the Texas Occupations Code, Chapter 1951 (relating to Structural
Pest Control) unless exempt under the Texas Occupations Code, Chapter
1951, Subchapter B (relating to Exemptions).
