First year teaching soldering to grade 11. Want to draft real safety procedures, not just "be careful."

My current draft:

• Safety glasses always when iron is on, no exceptions
• Hair tied back if longer than collar
• Soldering only at designated benches (ceramic top, fire-resistant)
• Wet sponge OR brass curl always on bench
• "Iron is hot, assume forever" rule, treat cold-looking iron as hot
• Hands washed after every session, before food
• No solo soldering, two-person minimum so help available

Lead solder vs lead-free: I want lead-free for student safety. Pricier but no heavy-metal exposure concerns.

What else am I missing? Other teachers, what incidents have you had despite procedures?
