Cyanuric acid can be oxidized by hypochlorite, in concentrated solutions, in the following manner, forming nitrogen trichloride as an intermediate.

H3Cy + OH- --> H2Cy- + H2O

Cyanuric acid + hydroxide --> Cyanurate + water

H2Cy- + 2ClO- --> Cl2Cy- + 2OH-

Cyanurate + hypochlorite --> dichloroisocyanurate + hydroxide

Cl2Cy- +7ClO- + 4H2O --> 3NCl3 + 2CO2 + HCO3 - + 7OH-

Dichloroisocyanurate + hypochlorite + water --> Nitrogen trichloride + carbon dioxide + bicarbonate + hydroxide

3NCl3 + 9OH- --> 1.5N2 + 4.5ClO- + 4.5Cl- + 4.5H2O

Nitrogen trichloride + hydroxide --> nitrogen gas + hypochlorite + chloride + water


H3Cy + 4.5ClO- --> 1.5N2 + 4.5Cl- + 3CO2 + 1.5H2O

Our city council has added criteria to their permit requirements for a pools and hot tub to state that "Pool chemicals must be stored in a safe, vented and locked container or in a building out of the reach of children".
I assume most people would simply put one cabinet in their garage and store everything inside, which is quite dangerous.

Is it dangerous storing pH+ with pH-, or Chlorine with neutralizer?
Are there any precautions necessary for Filter cleaners clarifies, liquid cover, or stabilizer,
