4. FIRST AID MEASURES
FIRST AID PROCEDURES
Move 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 attention 
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, repeat flushing and obtain 
medical attention.
Skin Contact:
Immediately flush eyes with running water for a minimum of 20 minutes.  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:
Medical supervision of all employees who handle or come in contact with respiratory sensitizers is 
recommended.  This should include preemployment and periodic medical examinations with respiratory 
function tests (forced expiratory volume, forced vital capacity as a minimum).  Persons with asthmatic-
type conditions, chronic bronchitis, other chronic respiratory diseases or recurrent skin eczema or 
sensitization should be excluded from working with this product.  Once a person is diagnosed as 
sensitized, no further exposure to any sensitizer should be permitted.
Medical conditions that may be aggravated by exposure to this product include diseases of the skin, 
eyes or respiratory tract ( asthma ).
Note to Physicians:
Prolonged, confined (especially under the finger nails, under rings or watch bands) or repeated 
exposure may cause skin irritation. Excessive contact with powder may cause drying of the skin due to 
absorption of moisture and oils. Prolonged and repeated contact may lead to dermatitis.
Skin Contact:
Not applicable.
Skin Absorption:
This product causes irritation, redness and pain.
Eye Contact:
This product may cause mild gastrointestinal discomfort. Ingestion of very high levels may cause weight 
loss.
Ingestion:
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.

6. ACCIDENTAL RELEASE MEASURES
Information in this section is for responding to spills, leaks or releases in order to prevent or minimize the adverse effects on persons, 
property and the environment.  There may be specific reporting requirements associated with spills, leaks or releases, which change from 
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. Avoid accumulation and dispersion of dust to reduce explosion potential.  
Wear respirator, protective clothing and gloves.  Avoid dry sweeping.  Do not use compressed air to 
clean surfaces.  Vacuuming or wet sweeping is preferred.  Any recovered product can be used for the 
usual purpose, depending on the extent and kind of contamination.  Collect product for recovery or 
disposal.  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
In common with many organic chemicals in powder form, this product may be capable of forming 
flammable dust clouds in air. Avoid accumulation and dispersion of dust to reduce explosion potential. 
Use normal "good" industrial hygiene and housekeeping practices. Clean up immediately to eliminate 
slipping hazard.
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, dry and well-ventilated area.  Keep away from heat, sparks and flames.  Keep 
containers closed.  Avoid moisture contamination.  Prolonged storage may result in lumping or caking. 
Protect from direct sunlight. Protect against physical damage.
Storage Requirements:
Confirm suitability of any material before using.

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
Local exhaust ventilation required.  Ventilation should be explosion proof. Make up air should be 
supplied to balance air that is removed by local or general exhaust ventilation. Avoid accumulation and 
dispersion of dust to reduce explosion potential. 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 dust-tight 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. Discard contaminated gloves.

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.
If while wearing a respiratory protection, you can smell, taste or otherwise detect anything unusual, or in 
the case of a full facepiece respirator you experience eye irritation, leave the area immediately.  Check 
to make sure the respirator to face seal is still good.  If it is, replace the filter, cartridge or canister.  If 
the seal is no longer good, you may need a new respirator.  (4)
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.

The ingredient(s) of this product is (are) not classed as carcinogenic by ACGIH, IARC, OSHA or NTP.
Carcinogenicity Data:
No adverse reproductive effects are anticipated.
Reproductive Data:
No adverse mutagenic effects are anticipated.
Mutagenicity Data:
No adverse teratogenic effects are anticipated.
Teratogenicity Data:
This product may cause respiratory sensitization or other allergic responses. Sensitization is the 
process whereby a biological change occurs in the individual because of previous exposure to a 
substance and, as a result, the individual reacts more strongly when subsequently exposed to the 
substance.  Once sensitized, an individual can react to extremely low airborne levels, even below the 
TLV, or to skin contact. See Section 11, "Other Studies Relevant to Material".
Respiratory / Skin Sensitization 
Data:
None known.
Synergistic Materials:
Guar gum has been reported to lower the serum and liver cholesterol levels in chickens and rats as well 
as the serum cholesterol and postprandial (after meal) blood glucose in humans.  When included at 
different levels in the diets of chickens, guar gum has been demonstrated to cause growth depression.  
Occupational asthma has been reported in subjects working with industrial production of guar gum.  (4)
