100mL 30% hydrogen peroxide
saturated potassium hydroxide solution
1 x 500mL measuring cylinder
dishwashing detergent
I signed off after adding the following under Control Measures:
using KI (not KOH) as per procedure reference
Additional measures: safety glasses, gloves
RiskAssess assessed KI but not the sat'd KOH as requested under 'Items to be prepared by lab tech' and another teacher has since re-ordered this prac. So what happens should a newbie innocently prepares the 'Teacher only' chemical as requested, with potentially disastrous consequences?
