DEFINITION OF NOTES
NOTE A - Security Storage - must be well ventilated with limited access.
NOTE B - Inorganic Alkali Storage - store away from acids by at least one 4 ft aisle width and away from
organic alkalis by at least one 4 ft aisle width.
Note C - Organic Alkali Storage - store away from acids by at least one 4 ft aisle width and away from
inorganic alkalis by at least one 4 ft aisle width.
NOTE D - Inorganic Acid Storage - store away from alkalis (caustics) by at least one 4 ft aisle width and
away from organic acids by at least one 4 ft aisle width. Separate from other acids with subsidiary risk
labels by at least one 4 ft aisle width.
NOTE E - Organic Acid Storage - store away from alkalis (caustics) by at least one 4 ft aisle width and
away from inorganic acids by at least one 4 ft aisle width. Separate from other acids with subsidiary risk
labels by at least one 4 ft aisle width.
NOTE F - Further separate into Acid and Alkali Storage within the low hazard storage area to keep
potentially incompatible products from mixing.
NOTE G - Separate from other oxidizers and oxidizers with secondary hazards by at least one 4 ft aisle
width.
NOTE H - Magazine Storage.
NOTE J - Segregate into flammable liquid storage separate from flammable solids by at least one 4 ft aisle
width.
NOTE K - Segregate into flammable solid storage separate from flammable liquids by at least one 4 ft aisle
width.
