CSCS Health, Safety & Environment Test — All Questions
4 questions
A safety sign that is a solid blue circle tells you that you:
- a.May do something if you wish
- b.Must not do something
- c.Are near an emergency exit
- d.Must do something, such as wear a hard hat or eye protection✓
Blue circular signs are mandatory: they tell you what you must do. Red circles with a diagonal line are prohibition (must not), yellow triangles are warnings, and green signs show safe conditions and escape routes.
Where does personal protective equipment (PPE) sit in the ways of controlling a risk?
- a.It is the last line of defence, used after other controls have reduced the risk as far as possible✓
- b.It is always the first and only control needed
- c.It removes the hazard completely
- d.It is optional decoration
PPE is the last resort in the hierarchy of control. Hazards should first be eliminated or reduced at source; PPE such as hard hats, boots and eye protection then protects against the remaining risk and only works if worn correctly.
Your safety helmet (hard hat) has taken a heavy knock. What should you do?
- a.Keep using it as normal
- b.Replace it, because a hat that has taken a significant impact may no longer protect you✓
- c.Paint over any cracks
- d.Only replace it after ten years no matter what
A helmet that has suffered a significant impact, or is cracked or damaged, must be replaced because its protective ability is reduced. Helmets also have a shelf life and should be checked regularly for damage.
A green safety sign on site normally indicates:
- a.A prohibited action
- b.A chemical hazard
- c.Safe conditions, such as first aid or an emergency escape route✓
- d.Mandatory hearing protection
Green signs show safe conditions: first-aid points, emergency exits and escape routes. Knowing your nearest escape route and assembly point before you start work helps you evacuate quickly in an emergency.
