Tips to facilitate Labeling of
Hazardous Art Materials (LHAMA) Certifications
Inadequate or missing information can delay the certification
process. To facilitate LHAMA certification, it is important to
provide the toxicologist with accurate information at the start of
the certification process. The information should describe
each ingredient in, and the complete
formulation of, the art material. LHAMA regulations constrain the
toxicologist from divulging proprietary information. The
following information added to your submission to the toxicologist
should help facilitate the certification:
1) For each ingredient in the art material, include the standard
internationally recognized chemical name of the ingredient and its
Chemical Abstract Number (CAS), and Color Index (C.I.) number of
colorants. 2) Include the amount by weight or percentage of each
ingredient in the total formulation of the art
material. 3) Summarize the market history, if any, of
the art material and whether it has resulted in health-related
customer complaints (if so, the nature
of the complaints). 4) Include results of all heavy metal
analyses of individual ingredients and the formulation,
and 5) Include relevant Material Safety Data Sheets (MSDS) for
each of the ingredients.
Also it is helpful to accurately and completely identify the art material by including the full, and complete name of: 1) the Producer and/or Repackager of the art material, 2) the distributor of the art material, if known, and 3) the specific product name and identifying number for the art material.
Providing the certifying toxicologist with this information before the review is undertaken should facilitate the LHAMA review and certification, and help assure that the certification report is completed promptly and accurately.
The American Society for Testing and Materials (ASTM) practice D-4236-88 as incorporated into 16 CFR Part 1500.14 (b)(8)(i)(B)(11) defines a toxicologist as "an individual who through education, training, and experience has expertise in the field of toxicology, as it relates to human exposure, and is either a toxicologist or physician certified by a nationally recognized certification board."
These regulations require that, "The producer or repackager shall submit art material product formulation(s) or reformulation(s) to a toxicologist for review, such review be in accordance with paragraph (b)(8)(1)(D)" of 16 CFR 1500.14.
In evaluating the chronic hazard of the art material, the
toxicologist is to take into account:
1) the chemical
composition of the art material,
2) the scientific knowledge of
each component and the total formulation,
3) the physical and
chemical form of the product, bioavailability, concentration, and
the amount of each potentially chronic toxic component in the
formulation,
4) reasonable foreseeable uses of the art material
product as determined by consultation with teachers, and other
individuals who are experienced in use of the material(s),
5)
potential for known synergism and antagonism of the various
components in the formulation,
6) potentially chronic adverse
health effects of decomposition or combustion products, if known,
from any reasonably foreseeable use of the hazardous art material
product, and
7) opinions of various regulatory agencies and
scientific bodies concerning the components and the product.
Based upon the conclusions reached as conformance with review determinations the toxicologist(s) shall recommend precautionary labeling that is consistent with that set forth by the standard.
