Take care when working around your pool, and spend some time making sure others know the potential dangers that exist in other areas of the pool – aside from the acknowledged threat of drowning or near-drowning.

Top 5 areas of swimming pool dangers

1. Diving Boards: Basic pool diving board rules include No Horseplay, One at a Time, Look before you leap, etc. This should be reinforced with all swimmers. If too many swimmers are using the pool, “close the board” to diving. Head injuries are common when divers slip or don’t dive outwardly. The most tragic of diving board accidents are spinal injuries when divers make contact with the pool floor. Most of these happen to be Male, between 18-35 years old, a bit overweight and also perhaps a bit tipsy. These accidents continue to put young men in wheelchairs at an alarming rate. Your pool may not be deep enough for a diving board, and if so, remove it from the pool deck.

2. Pool Chemicals: In the water, doing their job? Not really, what we are talking about here are pool chemicals transported and stored improperly. Keep all pool chemicals secure, in a cool and dry location, out of the reach of children. If you have lots of old pool chemicals laying around, with bags torn open, or the plastic bucket is cracking – find the time to make a trip to your local landfill to dispose of – or add them to the pool if suitable. Chlorine and Acids (pH down) are especially hazardous and must always be sealed tightly – and kept dry and seperated. Keep all chemicals from any possibility of mixing. For more pool chemical safety information.

3. Pool Electrical: The pool pump, pool lights, pool heaters, salt systems and controllers all use some form of electricity. Make sure that the conduit (the rigid or flexible tube containing wires) is replaced when it shows signs of wear and tear. Pool lights, installed incorrectly have electrified pools, have resulted in death. Timer clocks, and breaker panels contain enough amperage to stop a weak heart. Make sure that your circuits are properly grounded and the steel equipment properly bonded.  I guess we should also consider lightning. All swimmers out of the pool when you hear thunder, as lightning is attracted to water. Finally, never use an electrical appliance within 10 feet of the pool, and always make sure you plug into a GFCI outlet (the type with the test button). Want more pool electrical safety information?

4. Main Drain Hazards: With the passage of the Virginia Graeme Baker Pool & Spa Safety Act in 2008, much attention has been brought upon entrapment injuries, most caused by powerful suction of pool or spa main drains. The new law requires public pools to replace single main drains with safer dual main drain setups, and/or install sensoring equipment to shut off pumps in the presence of a vacuum – or entrapment. Drains, or vacuum cleaner lines or any suction port that hair, or body parts can be sucked into, can trap even good swimmers of large body size. If your pool has a single main drain which has a dedicated line running all the way to the pump, make sure that new, safer drain covers are installed. Also consider modernizing to a dual drain system, or installing sensoring equipment, as mentioned above. Follow this link for more information on main drain pool safety.

5. Solid Pool Winter Covers: Sure, mesh safety covers are very safe, but the solid pool cover, held in place with water bags and such, or clamped around the edge of an above ground pool, are definately not safe. Solid pool covers, if a small child or animal falls on them, wrap themselves around the legs and body of the victim, with rushing cold water on top of the cover enveloping the person. Keep solid pool covers firmly anchored, and keep your cover pump operational, and limit or prevent access to the pool area during the winter.

1. Store pool Chemicals out of Reach of Children: This would mean on an upper shelf or locked cabinet.

2. Store pool chemicals in a cool, dry location. Very hot or wet locations can cause fumes to develop inside the bucket or bag.

3. Store pool chemicals in separate locations. Keep acids far away from chlorine. Keep different chlorine types separated. This is especially important while transporting pool chemicals. In the event of an accident, mixed pool chemicals could shut down the beltway!

4. Do not allow any contamination of pool chemicals. The smallest amount of foreign substances, such as other pool chemicals, flecks of leaves or dirt – can react with your pool chemicals, resulting in fire or explosion.

5. Use a clean, dry chemical scoop. Small flecks or dirt or trace amounts of other pool chemicals can react violently.

6. Keep all pool chemical lids on tightly. Lock them down – they are fairly childproof, if installed correctly.

7. Never Mix Pool Chemicals. Add them to the pool separately.

8. Add chemicals to water – not water to chemicals. When pre-mixing a chemical solution – fill the bucket with water, and add the pool chemical to the bucket, while stirring.

9. While adding pool chemicals, be up-wind. Strong winds can blow broadcasted chemicals back into your face, or all over the pool deck.

10. Follow all packaging instructions. All pool chemicals have very specific instructions in use and storage. For instance. 1lb shock packages will tell you to use the entire packet at one time. Half full bags of shock laying around is quite dangerous!

Many pool service companies base their business model on weekly or bi-weekly visits to the customer’s home to service the pool.  We’ve accepted that as a fiberglass pool company, that’s not a viable business model for us…..because our customers simply don’t need it. 

 Of our 600 or so fiberglass pool customers, I’d estimate that less than 1% have their pools serviced on a regular basis…..and that’s only because they’d rather not fool with it (and good for them!).  So why don’t fiberglass pools require regular servicing like concrete pools?

Here are 3 Reasons Your Fiberglass Pool Won’t Require Weekly Service

#1. pH Stays Balanced

Fiberglass pool shells are chemically inert which means they do not react with the pH of the pool water.  Concrete pools, on the other hand, are alkaline based.  Consequently, they require the addition of acid on a regular basis to counteract the rising pH. 

One of the primary functions of the weekly service is to check and adjust the pH of the pool water.  Because most fiberglass pools only require pH adjustment once or twice a season, verses on a weekly basis with concrete pools, the dependency on anyone else is greatly reduced. 

#2.  Little or no Wall Brushing

The surface of concrete pools is extremely rough and porous.  Each of these tiny little nooks and crannies is like a four star hotel for algae.  Well, in order to evict this unwanted guest the surface of the pool requires regular brushing.  If this is neglected, the algae will invite their friends and the next thing you know their trying to conquer the world (think Plankton from Spongebob!).

The surface of fiberglass pools, on the other hand, is smooth and virtually non-porous and therefore prohibits algae from taking hold.  That means less brushing, and less work….another reason you can do this yourself.

#3. Use Less Chemicals

Fiberglass pools, again because of their non-porous surface, require less chemicals to keep the water clean and sanitary.  Just as pool service companies check pH during each trip, they also test and adjust the sanitizer lever (aka Chlorine) of the water.  Because fiberglass pools consume less sanitizer, less time is spent testing and adjusting.

As you can see, it’s the surface of these two pools that is the biggest differentiator.  The surface of concrete pools is alkaline (along with the shell) and very porous, where fiberglass pools are inert and non-porous.  This single factor, the way the surface reacts in water, makes a world of difference in terms of maintenance, and is what allows fiberglass pool customers to maintain their own pool without spending their hard earned money on regular service trips.
