Risk Assessment Author: Douglas Macdonald





Introduction

This is a science comedy show, in the form of a University Lecture, about the real science behind Zombies. It is delivered by Doctor Austin, head of Institute. As this follows the format of a University Lecture with slides, talk and a few demonstrations, it is generally low risk. The demonstrations do not involve any hazardous materials and the projectile experiments utilise only children's toys. The specific risks and additional measures to mediate these are detailed below.


General trip and slip hazards


With stage equipment and wires there are potential trip hazards for the performer and members of the public being invited onto the stage. Further more some of the experiments provide a potential slip hazard.
  • Risk Rating (Calculated using the risk rating table)
    • Likelihood: Low
    • Severity: Medium
    • Risk rating: Medium
  • Additional Controls to reduce risk to as low as reasonably practicable, (ALARP)
  1. The performer remove trip hazards before show.
  2. The performer should have material to clean up slip hazards during the show.
  3. The performer should maintain a tidy stage during the show.
  4. When invited onto the stage, the performer should brief and maintain control of participants.
  5. The performer should make sure that slip hazards are cleaned up during the show.
  • Final Risk Rating:
    • Likelihood: Low
    • Severity: Medium
    • Risk rating: Medium
Conclusions
Given that the staging environment is safe and that the trip and slip hazards are no worse than the every day, a medium risk rating is fair assessment. 



Zombie Bite

Hazard

This experiment simulates a Zombie bite by asking a volunteer to eat into a Swiss Roll

Risks
  1. Allergic reaction to ingredients
  2. Choking
Allergic reaction to ingredients
  • Risk Rating (Calculated using the risk rating table)
    • Likelihood: Low
    • Severity: High
    • Risk rating: High
  • Additional Controls to reduce risk to as low as reasonably practicable, (ALARP)
  1. The volunteer should be given the opportunity to refuse the food. 
  • Final Risk Rating:
    • Likelihood: Low
    • Severity: Medium
    • Risk rating: High
Choking
  • Existing control measures
  1. Being a soft cake, even if choking occurs it should be easily cleared.
  • Risk Rating (Calculated using the risk rating table)
    • Likelihood: Low
    • Severity: Low
    • Risk rating: Low
  • Additional Controls to reduce risk to as low as reasonably practicable, (ALARP)
  1. Some water may assist. 
  • Final Risk Rating:
    • Likelihood: Low
    • Severity: Low
    • Risk rating: Low
Conclusions
Given that the likelihood is low that anyone with a relevant life-threatening food allergy would freely volunteering for this experiment the final risk rating of 'high' is unfounded and therefore assessed as low.  The soft nature of the cake itself also renders its choking risk low.



Simulation of bashing the brain

 
A volunteer is asked to bash dummy brain with a weapon. The dummy brain is usually a cauliflower and the weapon a feather duster.

Hazards
  1. Slip - slip hazards and control are handled under general trip hazards above. 
  2. Flying vegetable
Risks
  1. Eye injury from flying debris

Eye injury
  • Existing control measures
  1. The dummy brain is soft and non-penetrating.
  • Risk Rating (Calculated using the risk rating table)
    • Likelihood: Low
    • Severity: Medium
    • Risk rating: Medium
  • Additional Controls to reduce risk to as low as reasonably practicable, (ALARP)
  1. The volunteer and anyone close-by should wear goggles.
  • Final Risk Rating:
    • Likelihood: Low
    • Severity: Low
    • Risk rating: Low

Conclusions
This is clearly a low hazard to the eyes. However, during the activity their may be an additional slip hazard and the presenter may have to intervene to stop the activity. At most this is a medium risk activity.   



Cross bow

Despite the title, this is demonstration is based on a child's sucker firing toy cross bow. The crossbow is used to aim at targets held by Doctor Austin. 

Hazards
The fast moving ' crossbow bolts'.

Risks 
Eye Injury.

Eye injury
  • Existing control measures
  1. The cross bow bolts are toy with a sucker on the end.
  2. These have additionally been tipped with a spongy material.
  • Risk Rating (Calculated using the risk rating table)
    • Likelihood: Medium
    • Severity: Medium
    • Risk rating: High
  • Additional Controls to reduce risk to as low as reasonably practicable, (ALARP)
  1. The volunteer and anyone close-by should wear goggles.
  2. The volunteer should be given instruction on how to operate the crossbow safely.
  3. The volunteer should be allowed a practice.
  4. The shooter should be facing away from the audience at all times.
  5. Doctor Austin should be wearing adequate eye protection.
  6. The presenter should remain in control at all times.
  • Final Risk Rating:
    • Likelihood: Low
    • Severity: Medium
    • Risk rating: Medium
Conclusions
This is already an acceptable children's toy and with the additional control measures in place there is little chance of an eye injury. However, vigilance needs to be maintained to keep the risks low, therefore a medium risk is a fair rating.
