# Studio Safety and Materials

## Scope

This is general studio-safety guidance, not a substitute for workplace-specific industrial hygiene, SDS, equipment manuals, or local regulations.

## Silica dust

Ceramic clays and many glaze/raw materials can contain crystalline silica.

Respirable crystalline silica can cause serious lung disease.

Prioritize:
- wet methods;
- local exhaust/engineering controls;
- minimizing dry handling;
- HEPA-equipped cleanup when appropriate;
- good housekeeping;
- preventing dust from becoming airborne.

Avoid dry sweeping fine ceramic dust.

Do not rely on an ordinary face covering as the primary control for a dusty process.

Respirator selection/use in occupational environments may require a formal respiratory-protection program, fit testing, and other requirements.

## Dry mixing

When dry raw-material mixing is necessary:
- consult SDS;
- minimize dust generation;
- use appropriate ventilation;
- keep containers labeled;
- clean safely;
- avoid food/drink in material areas;
- avoid bringing contaminated dust home.

## Spraying glazes

Spraying can create aerosols and fine particles.

Use properly designed spray ventilation/booths and appropriate controls rather than assuming room ventilation is enough.

## Kiln safety

Follow the exact kiln manufacturer's manual.

Typical concerns include:
- electrical installation;
- combustibles/clearance;
- heat;
- fumes;
- ventilation;
- damaged elements/cords/thermocouples;
- fire safety.

Do not improvise wiring, gas, interlocks, ventilation, or safety controls from generic online advice.

## Hot work

Hot kilns and ware can cause burns and fire hazards.

Do not open or unload based only on impatience; follow safe temperature/manufacturer guidance.

## Glaze/raw materials

Material hazards vary.

Check:
- SDS;
- label;
- manufacturer instructions;
- local disposal rules.

Do not assume "natural," "ceramic," or "lead-free" means harmless to inhale, ingest, or handle without controls.

## Grinding/sanding fired ceramic

Grinding or sanding can generate respirable dust and sharp fragments.

Use appropriate engineering controls and task-specific PPE.

Avoid dry grinding silica-containing material without adequate controls.

## Studio habits

Keep:
- food/drink separate;
- containers labeled;
- floors/surfaces clean;
- kiln/material records;
- SDS accessible;
- training appropriate to equipment/materials.
