Section 3: Hazard Identification
Emergency overview
Appearance: Solid white powder.
Immediate effects: Slightly hazardous in case of skin contact (irritant, permeator), of eye
contact (irritant), of ingestion, of inhalation.
Potential health effects
Primary Routes of entry: Inhalation, Ingestion.
Signs and Symptoms of Overexposure: Ingestion of large doses may affect
behavior/central nervous system (tetany). However, if a significant amount of phosphate
is absorbed, hypophosphatemia will occur. Severe hypophosphatemia may result in
hypocalcaemia and tetany. Cardiovascular, respiratory, neurological, and musculoskeletal
effects may occur secondary to hypernatremia, hypophosphatemia, and hypocalcaemia.
Eyes: Causes mild eye irritation.
Skin: Slightly hazardous in case of skin contact (irritant, permeator). May cause
dermatitis.
Inhalation: May cause respiratory tract and mucous membrane irritation. Expected to be a
low hazard for usual industrial handling.
Ingestion: May cause irritation of the digestive tract and may cause purging. It is slowly
absorbed. Expected to be a low ingestion hazard for usual industrial handling.
Chronic Exposure: Skin: High and repeated exposure may cause dermatitis.
Chemical Listed As Carcinogen Or Potential Carcinogen: No
See Toxicological Information (Section11)
Potential environmental effects
See Ecological Information (Section 12)
Section 4: First Aid Measures
If accidental overexposure is suspected
Eye(s) Contact: Check for and remove any contact lenses. In case of contact, immediately
flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get
medical attention if irritation occurs.
Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get
medical attention if irritation develops. Cold water may be used.
Ingestion: Do not induce vomiting unless directed to do so by medical personnel. Never
give anything by mouth to an unconscious person. Loosen tight clothing such as a collar,
tie, belt or waistband. Get medical attention if symptoms appear.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.

Section 6: Accidental Release Measures
Steps to be Taken in Case Material is Released or Spilled: Small Spill: Use appropriate
tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and dispose of according to local and
regional authority requirements. Large Spill: Use a shovel to put the material into a
convenient waste disposal container. Finish cleaning by spreading water on the
contaminated surface and allow evacuating through the sanitary system.
Waste Disposal Methods: Dispose of waste according to Federal, State and Local
Regulations.
Section 7: Handling and Storage
Precautions to be taken in Handling and Storage: Keep container tightly closed in wellventilated area.
Storage temperature: Keep container in a cool.
Storage Pressure: NA
Section 8: Exposure Controls / Personal Protection
Engineering Controls
Ventilation required: Use process enclosures, local exhaust ventilation, or other
engineering controls to keep airborne levels below recommended exposure limits. If user
operations generate dust, fume or mist, use ventilation to keep exposure to airborne
contaminants below the exposure limit.
Personal Protection Equipment
Respiratory protection: Where protection from nuisance levels of dusts are desired, use
type N95 (US) or type P1 (EN 143) dust masks. Use respirators and components tested
and approved under appropriate government standards such as NIOSH (US) or CEN
(EU).
Protective gloves: Wear Gloves.
Skin protection: Lab coat and gloves.
Eye protection: Safety glasses, goggles or face shield.
Additional clothing and/or equipment: Lab coat.
