Risk Assessment: 
Experiment Geological TimeLine Scarf Limestone Composition Fossils and Replica Dinosaur Bones Plushy Visual Aids Scale Model of the Solar System Audience Half-Life Experiment
Description A ~30m scarf, colour-coded with each geological period.
To covey sheer size of geological time, how long humans have existed for and dinosaurs.
Audience volunteers unroll the scarf, stopping at key stages in geological history.
Dissolving Limestone and collecting the gas produced in limewater.
Observation of CO2 released.
For the use of demonstrator. Placed under the projector to display to the audience. Use of plushie dinosaurs and other soft “creatures” as a visual aid To display relative distance from Earth to the asteroid belt. Involves volunteers moving around the lecture room and props (sports balls to scale) Audience Members Stand Up / Wave Hands in Air and instructed to sit down at different intervals to represent radioactive decay
  • Tripping hazard
  • Strangulation Hazard
  • Glass Breaking
  • Vinegar / weak acid spray is irritant
  • Spill hazard – electrical
  • Spill hazard – chemical
  • Swallowing hazard
  • Dropping of fossils on feet
  • Falling on the floor and being a tripping hazard.
  • Tripping or falling whilst moving around the lecture theatre
  • Balls rolling and becoming a trip hazard
  • Swallowing of small marble sized balls
  • Young children falling over from standing on chairs
  • Action To Be Taken To Minimise Risks
  • Keep scarf off the floor to prevent tripping
  • Encourage volunteers not to unwind scarf too fast
  • Ensure scarf unwinding does not occur where there are electrical wires along the floor
  • Ensure that the scarf is kept at waist height
  • Keep glassware at the centre of the desk at all times.
  • Only the demonstrator holds glassware.
  • Only use small amounts of liquid
  • Demonstrators to wear goggles when pouring
  • Keep apparatus away from electrical components
  • Mop up any spillages promptly.
  • Have eyewash available
  • Keep all liquids when not in use out of sight and with lids on
  • Fossils to only be held in two hands by presenter.
  • Keep fossils at the centre of the projector
  • Ensure that soft toys are not on the edge of the table.
    If they fall, pick them up promptly.
  • Encourage all volunteers to walk, not run around the lecture theatre
  • Ensure the volunteers do not throw or kick the balls. When not in use, balls to be kept in a box to prevent them from rolling around
  • Do not use small parts if volunteers are very young children
  • Ask adults to ensure that children do not stand on the lecture theatre chairs
  • Action To Be Taken In The Event Of An Accident
  • Call a first aider in the event of injury
  • Call first aider in the event of reaction or injury
  • Parents may administer eyewash to their child
  • Advise vinegar/weak acid to be washed off
  • Call a first aider in event of injury
  • Call a first aider in event of injury
  • Call a first aider in event of injury
  • Call first aider in event of injury
  • This experiment contains mains electrical parts, see separate risk assessment.
