Had a look at the link provided by Clubman and was surprised by the lack on info. Plenty there on how to become a lifeguard, water quality, funding local authorities, hygiene, fire exits etc - but no info on pool safety requirements - typical of our Govt/LA bodies - the most important details are left vague, ambiguous or just missing!
Mir2001: When you spoke to the sales guy, did you specifically ask about lifeguards/pool safety? As you suggest, one can drown in a shallow pool, in fact a hell of a lot less than 4 ft.
IMHO, a lot depends on the pool size, occupancy and supervision. Non -Lifeguard pool supervisors might deal with most emergencies in water of this depth, but I'd hate to see someone untrained deal with an emergency involving someone heavy, or in major panic/distress. While some pools operate without lifeguards, ALL should have personnel trained in CPR on duty AT ALL TIMES.
If your discussion with the sales guy gave you false or misleading information then you may be entitled to a full refund. I suggest that you ask:
Are there personnel trained in CPR on duty whenever the pool is open?
Are there defibrillators on the premises?
Are staff trained & certified in their use?
Are there any qualified lifeguards on the staff?
Ask to see their emergency plan/protocol.
If the answers aren't positive, then I suggest walking, with or without the cash.
And, by the way, for those of you who use a gym, even without a pool........YOU need to be asking those questions too!! SCA - sudden cardiac arrest - is pretty common and there are a lot of fast buck fitness merchants out there!
