Next risk come ingestion, and the least (but still not safe) is from absorption through the skin. But these are infinitesimal compared to the risk from sanding and breathing dust.
The simplest way is to leave the old paint and create a barrier. Most old houses I've seen deal with this by building a false ceiling below the old one using modern materials.
Added advantage is this adds an air gap that helps with insulation.
Another barrier is to put new paint on top, but if it's pealing, that needs dealing with first (we are back to risky sanding) and it's probably oil paint which usually needs specific paint to stick to it long term.

I hate sheet-rocking over my head. It's heavy! I'd use wood paneling on 2x4 studs rather than sheet rock. But if I were doing that, I'd still give it elastomeric paint before I did. Lead dust is not a thing to skimp on, and it will continue flaking if not glued in by something evil (like that paint) and the flakes will wander out cracks.
So my vote would be a glue it down hard layer of some sort, followed if desired by a ceiling smoothing layer of some sort. But I would NOT skip the glue down layer, and regular cheap paint won't be mean enough.

Using elastomeric paint above a wood cookstove is not a safe option, particularly when there's a food drying rack between the stove and the ceiling. Here's why:
🔥 Why It's a Risk
1. Elastomeric Paint Isn't Heat-Resistant
Elastomeric coatings are designed for exterior walls and roofs for flexibility and waterproofing—not high heat.
Most are rated only up to 150–200°F (65–93°C). A wood stove can radiate heat to ceilings well above this, especially directly above it.
Off-gassing risk: When overheated, elastomeric paint may release toxic fumes, especially problematic near food.
2. Proximity to Food
A drying rack between the stove and ceiling means food is directly in line with:
Heat
Rising fumes
Potential off-gassing from paint
Even if the paint doesn’t visibly burn, volatile organic compounds (VOCs) could contaminate drying food.
âś… Better Alternatives
For Ceilings Above a Stove:
Use heat-resistant paint specifically rated for high temperatures (e.g., Rust-Oleum High Heat, or stove/fireplace paint).
Use a metal heat shield or cement board above the stove instead of paint if protection is needed.
Maintain clearances per stove manufacturer specs—often 36" or more to combustibles.
For Food Drying Areas:
Ensure food drying is done in an area with:
Clean, food-safe surfaces
Good air circulation
Protection from smoke/fumes
Avoid drying food in areas exposed to any kind of non-food-safe coatings or adhesives.
Summary
Do not use elastomeric paint above a wood cookstove, especially where food is drying. It poses a heat and toxicity hazard. Use heat-rated paint or a non-combustible barrier instead.
Let me know your ceiling material or layout if you'd like specific safer options.
