Yes. New antifreeze and used antifreeze has a sweet taste that small children and animals can find attractive. If ingested, antifreeze affects the central nervous system and can cause death. A couple of states in the US require the addition of a bittering agent to make antifreeze less tasty to children and animals. Every year about 10,000 cats and dogs are victims of accidental poisoning by ingestion of antifreeze.

If there is any possibility that a rupture of the tubing could contaminate the potable water, use non-toxic propylene glycol. If contamination is impossible, automotive type ethylene glycol may be used. See similar questions...

Use a 50% solution of glycol based antifreeze solution to water for a system that must operate at very low temperatures. If only freeze protection is needed, a 20-25% solution is usually adequate because the more dilute solution forms a non rigid slush that will not flow well but will not damage the tubing.

The other family of domestic poisonous snakes is Elapidae, which includes two species of coral snakes found chiefly in the Southern states. See similar questions...

Although all true spiders have venom glands, not all venoms produced are very poisonous to humans. In fact, only two spiders in Texas are known to have the potential to commonly cause severe reactions: the brown recluse and the black widow. However, any spider bite could cause a reaction, especially if you are hypersensitive to that particular venom. See also the Medically Important Arthropods page for more information and pictures.

Dry Powder Chemical extinguishers are very basic and comparatively inefficient fire fighting technology. See similar questions...

There is a site out there that says that daddy long leg spiders are the most poisonous spider in all the world, but its fangs are too small to bite humans.
