Revise: Hazards and RisksA hazard is the source of possible harm. The risk describes how likely that harm is and how serious it could be. For example, a glass test tube is not itself an injury: cracked glass is the hazard, while being cut is the possible harm.
Something with the potential to cause harm.
Link each control measure to a named hazard and explain how it reduces either the likelihood or severity of a specific harm.
Do not write only “be careful” or “wear protective equipment”. Give a precise action suited to the hazard, such as placing hot apparatus on a heatproof mat or wearing eye protection when a chemical could splash.
Keep the hazard and the possible harm separate: broken glass is a hazard; a cut is the possible harm.
