Question 3

What does 'effective chlorine' refer to in the context of pool water disinfection?

Answer

The chlorine concentration in the deepest part of the pool

Answer

The chlorine measured after 30 minutes contact time

Question 4

What action should a lifeguard take when they see lightning while supervising an outdoor pool?

Accepted Answer

Clear the pool immediately — all bathers must exit the water and take shelter, as water conducts electricity

Continue supervision but advise bathers to exit if they feel uncomfortable

Answer

Close the pool only if lightning is within 5 km

Answer

Continue if the storm appears to be passing

Question 5

What is the significance of a 'pool incident investigation' following a near-miss event?

Accepted Answer

Near-miss investigations identify system failures before they result in a death, allowing preventive measures to be implemented

Answer

Investigations are only required for fatalities, not near-misses

Answer

Investigation findings are only shared with legal teams

Answer

Near-miss investigations are optional and carried out at management's discretion

Question 6

What does 'informed consent' mean in the context of first aid administered by a pool lifeguard?

Accepted Answer

A conscious, competent adult should be informed of proposed first aid and their agreement sought — although implied consent applies for unconscious casualties and children in emergency situations

Answer

The lifeguard must obtain written consent before any intervention

Answer

Consent is irrelevant in emergencies — lifeguards can always proceed

Answer

Consent must be obtained from the pool manager before first aid is administered
