The risk assessment document summarizes potential health and safety issues for a student film shoot taking place in a tunnel in Reigate. It identifies risks such as a cast member's cat knocking over equipment or tripping actors (medium risk), water on the floor or equipment in the bathroom (high risk), and narrow landings with many people (medium risk). For each risk, it proposes control measures like keeping the cat away, ensuring no water, and limiting people on landings to reduce risks to low levels.
