Chemical	Global formula	UN code	Danger Code	Recommended joints	Attributes and risks (from INRS chemical data sheet)	Storage guidelines
Acetic acid (<80 %)	CH₃COOH	2790	80 corrosive	EPDM	Contact with strong oxidizers may cause aggressive reaction. Reacts with most metals when there is air or water. It releases hydrogen gas. If emissions occurred, neutralize with sodium bicarbonate.	Prevent the use (at the Storage Station) of metal or any metallic object that could provoke a reaction if in contact with hydrogen releases. Avoid product solidification (above 16°C) by outfitting the tank with a reheating system using coiled pipes.
Acide chlorhydrique	HCl	1789	80 Corrosive Toxic	EPDM	Suffocating gas. Violent reaction to oxidizers (chlorine formation) and to basis (heat release)	Store in a cool and ventilated place. Keep away from direct sunlight, heat, inflammable substances and reactives. Storage floor must be waterproof. Electrical equipment must be waterproof and anti-corrosion.
Chromic anhydride	CrO₃	1755	80 corrosif toxique comburant	FPM (Viton)	Strong oxidizer whose inhalation may cause cancer. Causes inflammation of organic combustive matter. Violent reaction with reducers.	Store away from humidity. Generally store in a HDPE tank. Tank must be place on a waterproof surface made of materials resistant to oxidation and acids.
Hydrofluoric acid (<60 %)	HF	1790	86 Corrosive Highly toxic	EPDM	Highly toxic when inhaled or swallowed or in contact to skin. Concentrated solution causes immediate injuries leading to more serious damage. Contact with metals may cause inflammation and explosion. It releases hydrogen.	Store in a HDPE tank
Formic acid	HCOOH	1779	80 Corrosive	EPDM	Flammable liquid whose vapour-air mixtures may become explosive. Contact with oxidizers causes fire and explosion..	Concentrated crystallization point of formic acid is 8°C, which may require the installation of a reheating system during cold weather.
Nitric acid (<70 %)	HNO₃	2031	80 Corrosive	EPDM	Strong oxidizer. Reacts explosively with organic or mineral materials, combustible and reductive materials. It destroys metals except noble metals (or platinum)	Foresee an spill containment tank. The tank must have a section air vent sufficiently large to evacuate air when being filled ,or to allow air penetration during discharge. In case the tank is not manufactured in HDPE,install a device to avoid humidity to penetrate inside the tank.
Per acetic acid	C₂H₄O₃	3109	80 Corrosive Harmful	EPDM	It may cause fire after a collision, friction or when lightly exposed to heat (it may be extinguished using pulverized water). Store away from reducers, oxidizers and basis. Causes skin, eyes and mucosa irritation.	Store away from reducers, bases and oxidizing materials. Keep in a dark place and away from reducers, bases and oxidizing materials and any source of heat. Consider the currently in force legislation for classified installations (Rubric ICPE 1200)
Phosphoric acid (<75 %)	H₃PO₄	1805	80 Corrosive	EPDM	Strong reaction with basis. Destroys most metals and releases hydrogen gas.	Keep the acid above -20°C to avoid crystallization.
Sulphuric acid (<98 %)	H₂SO₄	1830	80 corrosif	FPM (Viton)	Explosive if water is poured on it. Violent reaction if it comes in contact with heat. May become explosive if it comes in contact with several organic materials, powder metals, carbides, chlorate, etc.	Foresee a spill containment tank. Keep inside tightly closed containers in a properly ventilated area, away from heat, sparks and flames. Place away from combustibles, bases and reducers.
ammonium aydroxide (alkali solution)	NH₄OH	2672	80 Corrosive Irritant	EPDM	Highly toxic for aquatic organisms. Releases a suffocating gas (ammonia NH3) which may become explosive if it comes in contact with air. Violent reaction on several oxides and peroxides.	Store the container in a well-ventilated place, at a temperature below 50°C. Prevent chemicals to come into the container. Prevent water suction inside the container. Store away from gas oxidizers and other types of oxidizers. Keep away from all sources of ignition (including electrostatic charges) Purge installation air before introducing the gas.
Aqualenc	Al₂O₃	3264	80 Corrosive Irritant	EPDM	Causes eye irritation. Easily penetrates the soil. If widespread, neutralize with lime or sodium carbonate. Reacts with basis and oxidizers.	Be sure of a proper ventilation. Foresee an adapted spill containment system. Product remains stable for at least 6 months in normal storage conditions. Store away from heat.
Sodium bisulfite	NaHSO₃	2693	80 Corrosive Harmful	EPDM	Yellowish liquid. Strong sulphuric anhydride odour. Releases a toxic gas if it comes in contact with an acid. Corrodes aluminium. Harmful for aquatic organisms. When released into the air it oxidizers and releases sulphuric acid and corrosive steams.	Store to a temperature range between 5° and 40°C. Cannot stand freeze not high temperatures. Recommended material for tank manufacturing: HDPE, PPH, stainless steel. Foresee an insulation material on top of the tank or a re heater (heating pins must be prohibited)
Sodium chlorite (<35 %)	NaClO₂	1908	80 Corrosive Harmful	EPDM	Light yellow liquid. Harmful when swallowed. Risk of severe eye injuries. Highly toxic for aquatic organisms. Releases a toxic gas if it comes in contact with an acid (chlorine dioxide)	Store at a temperature below 50°C and in a properly isolated place. Protect from heat and light. Tank must be exclusively used for the storage of this product.
Ferric chloride	FeCl₃	2582	80 corrosive	EPDM	Aqueous dark brown solution. Strong odour. Mucosa irritant. Reacts as an acid when mixed with water. Destroys metals and releases hydrogen.	Store away from all kinds of humidity. Requires a tank including a spill containment.
clairtan	FeCISO₄	3264	80 corrosive	EPDM	Brownish green solution. Released chlorhydrique acid when decomposed. Causes irritation to skin, eyes and mucosa. Smokes coming from fire are hazardous. Stop spillage using sand and soil. Do not release to the environment.	Store away from all sources of heat. Protect from freeze. Requires a tank and a spill containment. Foresee the use of waterproof and corrosion-resistant electrical installations. Pump or gravity discharge required. In case of trouble do a compressed air discharge.
Formaldehyd	HCHO	2209	80 toxic	EPDM	Colourless and suffocating gas. Strong odour. Causes cancer. Reacts with strong oxidizers, acids and basis. Easy polymerization (especially in cool environments).
