1. You are going to drill holes in pieces of steel
You are going to drill holes in pieces of steel. Before starting, your manager has asked you to identify the hazards that may be encountered.
List the mechanical and non-mechanical hazards you might encounter
Suggest measures that could be used to control these hazards.

2. Forewarned is Forearmed: What should an employer do to warn employees of hazards in the workplace?
Safety Signs
Task:
When instructed to do so, move quietly to room 0.07.
Make a note of the warning signs you see.
What colours are they?
What shapes are they?
What do they warn/tell you about?
Take photos if you like.
Return to 0.19 quietly.

5. What is the difference between a hazard and a risk?
“A hazard is anything that may cause harm”
“A risk is the chance, high or low, that somebody could be harmed by the hazard, together with an indication of how serious the harm could be”
Health & Safety Executive

6. Assessing “Risk”
Risks can be identified as either “trivial” or “significant”.
First, list the hazards.
Second, identify who might be affected by each hazard and how.
Third, score the “likelihood” of being harmed.
(1 = very unlikely, 5 = extremely likely)
Fourth, score the severity of any injury caused.
(1 = minor injury, 5 = fatality)

7. Example: Changing a wheel on a car
Hazards
Persons affected
Likelihood
Severity
Risk Factor
Trivial or Significant
Collapse of lifting jack
Mechanic – crushing
Other employees – crushing
Risk Factor = Likelihood x Severity
Risk factors above 4 are considered significant

8. TASK
Select a typical task that might be carried out in an engineering environment.
Draw a table, as on the previous slide, identifying:
Hazards
Who might be affected and how
Likelihood
Severity
Risk factor
Whether the risk is significant or trivial

9. TASK
Consider countermeasures for each of the hazards previously identified.
How would the likelihood and severity be affected?
Hence, what impact would this have on the risk factor?
