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:
Prompt removal of the material is essential. Flush skin with running water for a minimum of 20 minutes.  
Start flushing while removing contaminated clothing.  If irritation persists, repeat flushing.  Obtain 
medical attention IMMEDIATELY.  Do not transport victim unless the recommended flushing period is 
completed or flushing can be continued during transport.
Skin Contact:
Prompt removal of the material is essential. 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 IMMEDIATELY.  Do not transport victim until the recommended flushing period is completed 
unless flushing can be continued during transport.
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.  IMMEDIATELY contact 
local Poison Control Centre.  Vomiting should only be induced under the direction of a physician or a 
poison control centre.  If spontaneous vomiting occurs, have victim lean forward with head down to 
avoid breathing in of vomitus, rinse mouth and administer more water.  IMMEDIATELY transport victim 
to an emergency facility.
Ingestion:
This product contains materials that may cause severe pneumonitis if aspirated.  If ingestion has 
occurred less than 2 hours earlier, carry out careful gastric lavage; use endotracheal cuff if available, to 
prevent aspiration.  Observe patient for respiratory difficulty from aspiration pneumonitis.  Give artificial 
resuscitation and appropriate chemotherapy if respiration is depressed.
Due to the severely irritating or corrosive nature of the material, swallowing may lead to ulceration and 
inflammation of the upper alimentary tract with hemorrhage and fluid loss.  Also, perforation of the 
esophagus or stomach may occur, leading to mediastinitis or peritonitis and the resultant complications. 
(3)
Activated charcoal mixture may be administered.  To prepare activated charcoal mixture, suspend 50 
grams activated charcoal in 400 mL water and mix thoroughly.  Administer 5 mL/Kg, or 350 mL for an 
average adult.
Medical conditions that may be aggravated by exposure to this product include neurological, 
cardiovascular disorders, diseases of the skin, eyes or respiratory tract.
Note to Physicians:
Causes severe eye irritation. May cause corneal damage and conjunctivitis.
Eye Contact:
This product causes irritation, a burning sensation of the mouth and throat and abdominal pain.
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.
Symptoms of potassium poisoning may occur.  These include slow heartbeat, accelerated breathing, 
muscle weakness and, in severe cases, paralysis.

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. 
See Section 13, "Deactivating Chemicals". Wear protective clothing. Collect product for recovery or 
disposal.  For release to land, or storm water runoff, contain discharge by constructing dykes or 
applying inert absorbent;  for release to water, utilize damming and/or water diversion to minimize the 
spread of contamination.  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. Containers exposed to heat may be 
under internal pressure.  These should be cooled and carefully vented before opening.  A face shield 
and apron should be worn.

Ventilation Requirements:
Use only with adequate ventilation and avoid breathing vapours, mists and aerosols. 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. 
Protect from direct sunlight. Protect against physical damage.
Storage Requirements:
Materials of construction for storing the product include:   carbon steel, plastics and cast iron. 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
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 vapours 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 rubber should be impervious under conditions of use.   
Discard contaminated gloves. Prior to use, user should confirm impermeability.

No specific guidelines available. A NIOSH/MSHA-approved air-purifying respirator equipped with dust, 
mist, fume cartridges for concentrations up to 50 mg/m³. 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)
