Understanding the CL Seal on Art Materials Before You Buy

What is the difference between the CL and AP seals in the ACMI certification program?

The AP seal confirms a product meets the standard for non-toxic, safe use by all age groups, while the CL seal indicates the presence of substances requiring specific health warnings for professional users.

Use these categories to quickly filter products based on the intended user and the environment where the art will be created.

Which specific health risks are associated with products carrying the CL seal?

CL-labeled products contain ingredients that pose risks ranging from immediate irritation to long-term systemic damage if handled improperly.

• Cadmium pigments are frequently found in professional-grade oil paints and can cause kidney damage or respiratory issues if inhaled as dust or ingested.
• Cobalt compounds present in certain mediums may lead to skin sensitization or allergic contact dermatitis upon repeated exposure to the skin.
• Solvent vapors released by thinners or varnishes can trigger dizziness, nausea, or central nervous system depression if used in poorly ventilated areas.
• Lead-based materials, though rare in modern supplies, can cause neurological impairment if absorbed into the bloodstream over time.

Are art materials labeled with the CL seal safe for use by children?

No, children should never use materials bearing the CL seal because their developing bodies are more susceptible to the toxic effects of heavy metals and solvents. These products often fail the ASTM D-4236 standard required for materials intended for use in schools or by individuals under 12 years of age.

What criteria does the Art and Creative Materials Institute use to determine if a product requires a cautionary label?

The ACMI evaluates products based on the toxicological assessment of every ingredient in a formula, specifically looking for substances that could cause chronic illness, such as cancer or organ damage. They rely on independent toxicologists to review the concentration of these chemicals and determine if they exceed safe thresholds for human exposure during normal use.

For example, a paint containing a high concentration of crystalline silica would trigger a CL label due to the risk of silicosis if the dried pigment is sanded and the dust is inhaled. A nuance exists where a product might be labeled as safe for adults but still carry a warning for specific groups, such as pregnant women, if the ingredients are known to be reproductive toxins.

How should art supplies marked with the CL seal be stored and handled to minimize exposure?

Store these materials in a locked cabinet or a sealed plastic bin to prevent accidental contact by others. Keep them at least 5 feet away from food preparation areas and make sure the containers remain tightly closed when not in use to stop the accumulation of hazardous vapors in the room.

What legal requirements govern the labeling of toxic art materials in the United States?

The Labeling of Hazardous Art Materials Act (LHAMA) mandates that manufacturers must evaluate their products for chronic health risks and provide appropriate warnings on the packaging. This law requires that any product containing materials that could cause chronic health issues must clearly state the hazards and provide instructions for safe handling. A lot of people assume that all art supplies sold in stores are automatically tested for safety, but the LHAMA only requires manufacturers to label products that have already been identified as containing specific hazardous ingredients.

Are there specific types of art media that are more likely to carry the CL seal than others?

Professional-grade media are more likely to carry the CL seal because they often prioritize high-performance pigments and binders that contain toxic heavy metals or volatile organic compounds.

• Oil paints often utilize heavy metal pigments like cadmium, cobalt, or manganese to achieve specific colors and lightfastness that synthetic alternatives cannot replicate.
• Printmaking inks frequently contain hazardous solvents or metallic driers necessary for the curing process on metal plates or woodblocks.
• Ceramic glazes often rely on lead, barium, or lithium compounds to achieve specific finishes and melting points during the high-heat firing process.
• Spray fixatives utilize potent propellants and resins that can cause significant respiratory irritation if the fine mist is inhaled during application.

What steps should a consumer take if they accidentally ingest or experience skin irritation from a product with a cautionary label?

Seek professional medical attention immediately if you ingest or experience a severe reaction to any art material labeled with a cautionary warning.

1. Rinse the affected skin area with cool, running water for at least 15 minutes to dilute and remove any remaining chemical residue.
2. Remove any contaminated clothing to prevent further skin absorption of the toxic substance.
3. Consult the product's Safety Data Sheet, which lists the specific chemical components and provides standardized emergency first-aid procedures for that formula.
4. Contact a local poison control center or a physician, providing them with the exact product name and the list of ingredients found on the packaging.
5. Do not induce vomiting if the substance was ingested unless explicitly instructed to do so by a medical professional or poison control expert.
