Figure 3 (a) shows a risk assessment table for a laboratory activity. It identifies the hazard type (chemical, electrical, other) each with one or more specific hazards. The associated risks are classified as tolerable, moderate, serious or intolerable.
Figure 3 (b) shows the laboratory activity – it involves a beaker containing a blue liquid and two metal strips. The strips are part of a circuit containing a power supply and two electrical meters. The experiment is wearing gloves whilst recording measurements.
