Particular pools and situations
A pool chemical spill
A chemical spill is a safety matter before it is a cleaning matter. Ventilate, keep people clear, and never mix one chemical with another.
Pool chemicals are concentrated, and a spill is handled as a safety matter first. The immediate steps are to move people away, ventilate the area, and avoid touching the spill with bare hands. The one rule that matters above all is never to mix chemicals, because two different pool chemicals mixed together can react violently.
These guides adapt pool care to a particular season, household or type of pool.
What happens next depends on the chemical and the size of the spill. Some spills can be contained and cleaned up carefully with the right precautions; others, and any spill that produces fumes, should be left to someone who works with pool chemicals. When in doubt, clear the area and call for help rather than improvising.

In practice

Mistakes to avoid
Mixing spilled chemicals
Two different pool chemicals mixed can react violently. Never combine them, even to clean up.
Improvising a big spill
