SIA Emergency Procedures 4 — Questions and Answers
Question 1: What is the recommended depth for chest compressions during adult CPR?
- 2-3 cm
- 5-6 cm (Correct answer)
- 8-10 cm
- 1-2 cm
Correct answer: 5-6 cm
The UK Resuscitation Council recommends chest compressions at a depth of 5-6 cm (approximately 2 inches) for adults. Compressions should be at the centre of the chest at a rate of 100-120 per minute, allowing full chest recoil between compressions.
Question 2: In the context of bomb threats, what does the mnemonic 'HOT' stand for?
- Have Others Tried, Order Tactical response, Tell headquarters
- Hidden, Obviously suspicious, Typical of the area
- Has it been Hidden? Is it Obviously suspicious? Is it Typical for this area? (Correct answer)
- Help Others Think, Observe Threats, Take action
Correct answer: Has it been Hidden? Is it Obviously suspicious? Is it Typical for this area?
The HOT protocol helps assess suspicious items: Has it been Hidden or concealed? Is it Obviously suspicious in appearance? Is it Typical - would you expect to find this item in this location? If the answer raises concern, do not touch it and call 999.
Question 3: What is the primary purpose of a 'cordon' at an incident scene?
- To keep the media away
- To create a controlled boundary that protects the public, preserves evidence, and allows emergency services to work safely (Correct answer)
- To prevent staff from leaving early
- To create a queue for re-entry to the venue
Correct answer: To create a controlled boundary that protects the public, preserves evidence, and allows emergency services to work safely
A cordon establishes a secure perimeter around an incident scene. It serves three purposes: protecting the public from hazards, preserving evidence from contamination, and providing a safe working area for emergency services.
Question 4: Which colour fire extinguisher is used for electrical fires?
- Red (water)
- Cream (foam)
- Black (CO2) (Correct answer)
- Blue (dry powder)
Correct answer: Black (CO2)
CO2 (carbon dioxide) extinguishers with a black label are safe for use on electrical fires as CO2 is a non-conductive gas. Water (red) and foam (cream) must never be used on electrical fires. Dry powder (blue) can also be used but leaves residue.
Question 5: A person is choking and cannot cough, speak, or breathe. After 5 back blows have failed, what is the next step?
- Call 999 and wait
- Perform 5 abdominal thrusts (Heimlich manoeuvre) (Correct answer)
- Begin CPR immediately
- Give them water to drink
Correct answer: Perform 5 abdominal thrusts (Heimlich manoeuvre)
If 5 back blows fail to dislodge the obstruction, perform 5 abdominal thrusts. Stand behind the person, place your fist between the navel and bottom of the breastbone, and pull sharply inward and upward. Alternate between 5 back blows and 5 abdominal thrusts until the obstruction clears or the person becomes unconscious.
Question 6: What does 'invacuation' mean in emergency procedures?
- A slower version of evacuation
- Moving people INSIDE a building for protection rather than evacuating them outside (Correct answer)
- A voluntary evacuation where people choose whether to leave
- Evacuating people from the upper floors only
Correct answer: Moving people INSIDE a building for protection rather than evacuating them outside
Invacuation is the process of moving people inside or further into a building for safety, rather than evacuating them outside. This may be appropriate during external threats such as a chemical spill, gunfire outside, or severe weather.
