What Not To Mix

The rules that keep everyone safe.

In an emergency, call first

Life-threatening emergency911Trouble breathing, unconscious, serious burns, or a gas leak. Call first.Poison Control1-800-222-1222Any chemical in eyes, on skin, swallowed, or inhaled. Free, 24/7, expert guidance.BlueLux Office601-258-3589Once the situation is safe, notify BlueLux to report any incident, spill, or accidental mix. Never call here instead of 911 or Poison Control.

Never mix acid with any chlorine

Muriatic acid plus liquid chlorine, trichlor, or dichlor releases toxic chlorine gas.

Never mix two chlorine types

Trichlor, dichlor, and liquid chlorine can react together and cause fire or explosion.

Keep oxidizers dry and sealed

Water or moisture in a tablet or shock pail builds pressure and can form an explosive compound.

One chemical at a time

Add a single product, let the pump circulate, then add the next. If you are unsure, check the product label and SDS before adding anything.

Golden rule

Add one chemical at a time and let it fully circulate before the next. If you are unsure, check the product label and SDS before adding anything.

Before adding any chemical

Safety glasses on
Gloves on
Working in open air, not an enclosed space
Product label and SDS reviewed

When you are not sure whether two products are safe together, do not combine them. Add one at a time, let the pump run, or check the product label and SDS before adding anything.
