Sodium and potassium hexametaphosphates, polyphosphates, tripolyphosphates,
pyrophosphates, and other phosphates used as water softeners form complexes with
calcium and, after ingestion, are capable of seriously reducing the serum level of ionic
calcium. They have less corrosive effect on mucous membranes than sodium or
potassium hydroxide. Hydrolysis of the polymeric phosphates can also produce acidosis.

Medical Surveillance:
In total parenteral nutrition ... potassium or sodium phosphate is essential; requirements
for phosphate are increased when glycolytic activity is increased or urinary losses are
high (eg, persistent acidosis proximal renal tubular defect). For /adults/ approximately
200 to 400 mg (6.5 to 13 mM) of phosphorus is required daily for maintenance, but larger
amounts are often needed when initiating total parenteral nutrition to maintain the serum
phosphate level above 2.5 mg/dl. For each 500 ml of 50% dextrose in water infused, 12
mM of phosphorus has been recommended.

Treatment Overview:
0.4.2 ORAL EXPOSURE
A) EMESIS: Ipecac-induced emesis is not recommended because
of the potential for CNS depression, seizures and
cardiovascular instability.
B) GASTRIC LAVAGE: Consider after ingestion of a
potentially life-threatening amount of poison if it can
be performed soon after ingestion (generally within 1
hour). Protect airway by placement in Trendelenburg and
left lateral decubitus position or by endotracheal
intubation. Control any seizures first.
1) CONTRAINDICATIONS: Loss of airway protective reflexes
or decreased level of consciousness in unintubated
patients; following ingestion of corrosives;
hydrocarbons (high aspiration potential); patients at
risk of hemorrhage or gastrointestinal perforation; and
trivial or non-toxic ingestion.
C) Hydrate with 0.9% of 0.45% saline as clinically
indicated. Correct hypocalcemia, hypomagnesemia,
hypernatremia, and hyper or hypokalemia. Monitor urine
output.
D) CONGESTIVE HEART FAILURE patients with an excessive
sodium load and normal renal function may be managed
with a diuretic such as furosemide (1 mg/kg IV to a
maximum of 40 mg).
E) SEIZURES: Administer a benzodiazepine IV; DIAZEPAM
(ADULT: 5 to 10 mg, repeat every 10 to 15 min as needed.
CHILD: 0.2 to 0.5 mg/kg, repeat every 5 min as needed)
or LORAZEPAM (ADULT: 2 to 4 mg; CHILD: 0.05 to 0.1
mg/kg).
1) Consider phenobarbital if seizures recur after diazepam
30 mg (adults) or 10 mg (children > 5 years).
2) Monitor for hypotension, dysrhythmias, respiratory
depression, and need for endotracheal intubation.
Evaluate for hypoglycemia, electrolyte disturbances,
hypoxia.
F) HYPOTENSION: Infuse 10 to 20 mL/kg isotonic fluid. If
hypotension persists, administer dopamine (5 to 20
mcg/kg/min) or norepinephrine (ADULT: begin infusion at
0.5 to 1 mcg/min; CHILD: begin infusion at 0.1
mcg/kg/min); titrate to desired response.
G) ATROPINE: ADULT DOSE: BRADYCARDIA: 0.5 to 1 mg IV every
5 min. ASYSTOLE: 1 mg IV every 5 min. Maximum total dose
3 mg or 0.04 mg/kg. Minimum single dose 0.5 mg.
PEDIATRIC DOSE: 0.02 mg/kg IV repeat every 5 min,
minimum single dose 0.1 mg; maximum single dose child
0.5 mg, adolescent 1 mg; maximum total dose 1 mg child,
2 mg adolescent.
H) Hemodialysis may be necessary to rapidly correct
hyperphosphatemia and hypocalcemia in severe cases.
0.4.3 INHALATION EXPOSURE
A) INHALATION: Move patient to fresh air. Monitor for
respiratory distress. If cough or difficulty breathing
develops, evaluate for respiratory tract irritation,
bronchitis, or pneumonitis. Administer oxygen and assist
ventilation as required. Treat bronchospasm with inhaled
beta2 agonist and oral or parenteral corticosteroids.
0.4.4 EYE EXPOSURE
A) DECONTAMINATION: Irrigate exposed eyes with copious
amounts of room temperature water for at least 15
minutes. If irritation, pain, swelling, lacrimation, or
photophobia persist, the patient should be seen in a
health care facility.
0.4.5 DERMAL EXPOSURE
A) OVERVIEW
1) DECONTAMINATION: Remove contaminated clothing and wash
exposed area thoroughly with soap and water. A
physician may need to examine the area if irritation or
pain persists.

/Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the
gastrointestinal tract. Transport of phosphate from the gut lumen is an active, energydependent process that is modified by several factors. ... Vitamin D stimulates phosphate
absorption, an effect reported to precede its action on calcium ion transport. In adults,
about two thirds of the ingested phosphate is absorbed, and that which is absorbed is
almost entirely excreted into the urine. In growing children, phosphate balance is
positive. Concentrations of phosphate in plasma are higher in children than in adults. This
"hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is
hypothesized to explain the physiological "anemia" of childhood. /Phosphates/

Once phosphate gains access to the body fluids and tissues, it exerts little
pharmacological effect. If the ion is introduced into the intestine, the absorbed phosphate
is rapidly excreted. If large amounts are given by this route, much of it may escape
absorption. Because this property leads to a cathartic action, phosphate salts are
employed as mild laxatives. Inorganic phosphate poisoning following ingestion of
laxatives that contain phosphate salts has been reported in adults and children. Ingestion
of large amounts of sodium dihydrogen phosphate lowers urinary pH. If excessive
phosphate salts are introduced intravenously or orally, they may prove toxic by reducing
the concentration of Ca 2+ in the circulation and from the precipitation of calcium
phosphate in soft tissues. /Phosphates/

1984, and determines whether they are eligible for reregistration. In addition, all
pesticides must meet the new safety standard of the Food Quality Protection Act of 1996.
Pesticides for which EPA had not issued Registration Standards prior to the effective date
of FIFRA, as amended in 1988, were divided into three lists based upon their potential
for human exposure and other factors, with List B containing pesticides of greater
concern and List D pesticides of less concern. Sodium phosphate is found on List D. Case
No: 4053; Pesticide type: Fungicide, herbicide, antimicrobial; Case Status: None of the
active ingredients in the case are being supported for reregistration by their registrants.
All are unsupported, or some are unsupported and some are cancelled. Cases described as
"unsupported" generally are being processed for cancellation.; Active ingredient (AI):
Sodium phosphate; AI Status: The active ingredient is no longer contained in any
registered pesticide products ... "cancelled."

Preventive Measures:
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The
benefit or detrimental effects of wearing contact lenses depend not only upon the
substance, but also on factors including the form of the substance, characteristics and
duration of the exposure, the uses of other eye protection equipment, and the hygiene of
the lenses. However, there may be individual substances whose irritating or corrosive
properties are such that the wearing of contact lenses would be harmful to the eye. In
those specific cases, contact lenses should not be worn. In any event, the usual eye
protection equipment should be worn even when contact lenses are in place.
