Section 06 - Accidental Release Measures
Personal Precautions / Protective
Equipment / Emergency Procedures
Wear appropriate personal protective equipment. Ventilate area. Only enter area
with PPE. Stop or reduce leak if safe to do so. Prevent material from entering
sewers. Flush with water to remove any residue.
Prevent material from entering sewers or confined spaces. Dangerous to aquatic life
in high concentrations. May be dangerous if it enters water intakes. Notify
government environmental agencies if material is released into the environment.
Methods and Materials for Containment Stop or reduce leak if safe to do so. Contain spill with earth, sand, or absorbent
material which does not react with spilled material. Do not get water inside
and Cleaning Up
containers or on spilled material. Contaminated absorbent material may pose the
same hazards as the spilled product.
Environmental Precautions
SMALL SPILLS: Neutralize with sodium bicarbonate (NaHCO3) or a mixture of soda
ash/slaked lime. Shovel residue into containers for disposal.
LARGE SPILLS: Recover liquid if it can be done safely. Place in suitable, covered,
labelled containers. Neutralize the solution remaining after recovery or the entire
spill cautiously with lime (CaO or soda ash (Na2CO3).
NOTE: Lime is the preferred neutralizing agent because of the low solubility of the
calcium phosphate formed. The residue (calcium phosphate) can then be shoveled
into containers for disposal.

Section 07 - Handling and Storage
Precautions for Safe Handling
Phosphoric acid is corrosive to the eyes and skin. Phosphoric acid will give off
flammable hydrogen gas on contact with many metals.
Use proper equipment for lifting and transporting all containers. Use sensible
industrial hygiene and housekeeping practices. Wash thoroughly after handling.
Avoid all situations that could lead to harmful exposure.
Immediately report leaks, spills or failures of the engineering controls. Use smallest
possible amounts in designated areas with adequate ventilation. Avoid generating
mists. Prevent the release of vapours or mists into the air. Unprotected persons
should avoid all contact with this chemical including contaminated equipment.
Always inspect containers for damage or leaks before handling them. Cautiously
dispense into sturdy containers made of compatible materials. Use the type of
container recommended by the manufacturer. Use corrosion-resistant transfer when
dispensing. Whenever possible, use self- closing, portable containers for dispensing
small amounts of this material. Never transfer liquid by pressurizing original
container with air or inert gas.
When preparing or diluting acid solutions, the acid should be added slowly to water
with plenty of careful stirring. This will prevent overheating, splashing and splattering
of the acid. Never use hot water and never add water to the acid. Water added to
acid can cause uncontrolled boiling and splashing. Protect from freezing.
Soda ash or lime should be kept nearby for emergency use. Label containers. Keep
containers closed when not in use. Empty containers may contain residues which
are hazardous. Never return contaminated material to its original container.
Containers of this material may be hazardous when empty since they retain product
residues (vapours, liquid), observe all warnings and precautions listed for the
product.
Conditions for Safe Storage
Storage of this product is influenced by the product supercooling at lower
temperatures without crystallizing. Many factors affect supercooling so actual
freezing point can be unpredictable.

Bioaccumulation
No bioaccumulation expected.
Mobility
When spilled onto soil, phosphoric acid will infiltrate downward, the rate being
greater with lower concentration because of reduced viscosity. During transport
through the soil, phosphoric acid will dissolve some of the soil material, in particular,
carbonate-based materials. The acid will be neutralized to some degree with
adsorption of the proton and phosphate ions also possible. However, significant
amounts of acid will remain for transport down toward the groundwater table. Upon
reaching the groundwater table, the acid will continue to move in the direction of
groundwater flow. A contaminated plume will be produced with dilution and
dispersion serving to reduce the acid concentration.
Other Adverse Effects
Dangerous to aquatic life in high concentrations. May be dangerous if it enters
water intakes. Notify local health and wildlife officials of any leaks/contamination.
