What helps an artist use colours and chemicals safely?

Correct answer: Following safety rules

Direct answer: Option B, following safety rules. Colours, solvents, adhesives, powders and other art materials may cause skin, eye or breathing problems if used carelessly. Step 1: read the label or instructions and learn the hazards. Step 2: use suitable protective equipment, such as gloves, an apron or eye protection when required. Step 3: work in a well-ventilated place and keep materials away from food, flames and the mouth. Step 4: store, clean and dispose of materials safely, and wash hands after work. Option B is correct because safety rules reduce exposure, accidents and harm to the artist and others. Option A, working without instructions, increases the chance of misuse and injury. Option C, keeping material in the mouth, can cause poisoning, choking or infection and must never be done. Option D, filling a closed room with smoke, creates dangerous inhalation and fire risks; ventilation is needed instead. Exact precautions depend on the material, so instructions and responsible supervision should be followed. Memory cue: read, protect, ventilate, store safely and never taste art materials.
