sneezing. See "Other Health Effects" Section.
Inhalation:
Skin contact can cause irritation, especially under the finger nails (and other confined spaces such as 
under rings or watch bands). Avoid handling when the skin is moist, wet or abraded. May cause 
defatting, drying and cracking of the skin. Prolonged and repeated contact may lead to dermatitis.

4. FIRST AID MEASURES
FIRST AID PROCEDURES
If respiratory problems arise, move the victim to fresh air.  Give artificial respiration ONLY if breathing 
has stopped.  Give cardiopulmonary resuscitation (CPR) if there is no breathing AND no pulse.  Obtain 
medical advice IMMEDIATELY.
Inhalation:
Start flushing while removing contaminated clothing. Wash affected areas thoroughly with soap and 
water. If irritation, redness, or a burning sensation develops and persists, obtain medical advice.
Skin Contact:
Immediately flush eyes thoroughly for 5 minutes with running water.  Hold eyelids open during flushing.  
If irritation persists, repeat flushing.  Obtain medical attention.
Eye Contact:
Do not attempt to give anything by mouth to an unconscious person. If victim is alert and not 
convulsing, rinse mouth out and give 1/2 to 1 glass of water to dilute material.  DO NOT induce 
vomiting.  If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing 
in of vomitus, rinse mouth and administer more water.  Obtain medical attention IMMEDIATELY.
Ingestion:
Treat symptomatically. Sodium salts have a hypothetical risk of hypernatremia.  In addition to calcium 
levels, sodium and phosphate levels should be monitored.
Medical conditions that may be aggravated by exposure to this product include diseases of the skin, 
eyes or respiratory tract.
Note to Physicians:
Effects (irritancy) on the skin and eyes may be delayed, and damage may occur without the sensation 
or onset of pain.  Strict adherence to first aid measures following any exposure is essential.
Sodium salts have a hypothetical risk of hypernatremia. May cause metabolic alkalosis. Metabolic 
alkalosis is a condition wherein the concentration of the arterial plasma bicarbonate concentration 
increases.

region to region.
In all cases of leak or spill contact vendor at Emergency Number shown on the front page of this MSDS. 
In common with many organic chemicals in powder form, this product may be capable of forming 
flammable dust clouds in air. Minimize air borne spreading of dust. Wear respirator, protective clothing 
and gloves.  Avoid dry sweeping.  Do not use compressed air to clean surfaces.  Vacuuming or wet 
sweeping is preferred.  Return all material possible to container for proper disposal. Do not allow to 
enter sewers or watercourses.
Any recovered product can be used for the usual purpose, depending on the extent and kind of 
contamination. Where a package (drum or bag) is damaged and / or leaking, repair it, or place it into an 
over-pack drum immediately so as to avoid or minimize material loss and contamination of surrounding 
environment. Replace damaged containers immediately to avoid loss of material and contamination of 
surrounding atmosphere. Ventilate enclosed spaces. Notify applicable government authority if release is 
reportable or could adversely affect the environment.
Containment and Clean-Up 
Procedures:
7. HANDLING AND STORAGE
HANDLING
Use normal "good" industrial hygiene and housekeeping practices.
Handling Practices:
See Section 8, "Engineering Controls".
Ventilation Requirements:
Use only with adequate ventilation and avoid breathing dusts. Avoid contact with eyes, skin or clothing.  
Wash thoroughly with soap and water after handling.  Wash contaminated clothing thoroughly before re-
use.
Other Precautions:
STORAGE
See below.
Storage Temperature (°C):
General exhaust is acceptable.
Ventilation Requirements:
Store in a cool, well-ventilated area.  Keep away from heat, sparks and flames.  Keep containers 
closed.  Do not expose sealed containers to temperatures above 40° C. Avoid moisture contamination.

Packaging or Containers:
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Recommendations listed in this section indicate the type of equipment, which will provide protection against overexposure to this 
product.  Conditions of use, adequacy of engineering or other control measures, and actual exposures will dictate the need for specific 
protective devices at your workplace.
ENGINEERING CONTROLS
General exhaust is acceptable. Local exhaust ventilation preferred. Make up air should be supplied to 
balance air that is removed by local or general exhaust ventilation. Ventilate low lying areas such as 
sumps or pits where dense dust may collect.
Engineering Controls:
PERSONAL PROTECTIVE 
EQUIPMENT (PPE)
Safety glasses with side shields are recommended to prevent eye contact. Use chemical safety goggles 
when there is potential for eye contact. Contact lenses should not be worn when working with this 
material.
Eye Protection:
Gloves and protective clothing made from cotton, canvas, rubber or plastic should be impervious under 
conditions of use.   Prior to use, user should confirm impermeability.
Skin Protection:
No specific guidelines available. A NIOSH/MSHA approved dust mask for concentrations of nuisance 
dust up to 100 mg/m³ particulate. An air-supplied respirator if concentrations are higher or unknown.
Respiratory Protection:
Wear an impermeable apron and boots. Locate safety shower and eyewash station close to chemical 
handling area. Take all precautions to avoid personal contact.
