Empiribox Primary Science Trust CIC: Chemical Change RA1 - Green Fire and Hydrogels Risk Assessment Location Written by Mark Inder School Class Room Class Date of assessment Category / Activity Demonstration and Experiment Risk Category High Med X Low Demonstration Green Fire Class experiment Hydrogels Description of Activity to be assessed Description The teacher will mix some ethanol (methylated spirits) and boric acid. The mixture will then be ignited to show a characteristic green flame. Description Pupils will investigate the absorptive properties of the hydrogels in different nappies. They will remove the hydrogel from the nappy and, after making their own urine with water and food dye, they will measure the volume of the hydrogel after adding the urine. HAZARDS* 1) The methylated spirit is highly flammable. It can also be harmful if inhaled or ingested 2) Boric acid may irritate the skin and eyes if it comes into contact with them. If ingested, it is rarely toxic but may induce diarrhoea, vomiting and nausea. 3) Sodium Polyacrylate can cause irritation to the respiratory tract if the dust is inhaled. Irritation may also occur if the dust comes into contact with the eyes and sensitive skin. Risk Assessment Lesson 1 & 2 - Green Fire and Hydrogels V1.0 24 August 2015 Page 1
