(HMIS codes are based on contact with the product as packaged and any hydrolysis by-products,
if present.) Hazardous Materials Identification System and HMIS are registered trademarks of
the National Paint and Coatings Association. Note: Respiratory protection is only recommended
in the event that ventilation or engineering controls are unable to maintain exposures below
recommended levels; or in the event of a spill or other emergency response situation.


Canadian WHMIS Classification: None.

3.2 Emergency overview and potential hazards

This material is not hazardous under OSHA criteria. This material is not hazardous under WHMIS
criteria.

Physical Hazards:

No known physical hazards.


Acute health effects

Route of entry or possible contact:

inhalation (in case of dust formation) , skin , eyes .

Eye contact:

May cause eye irritation.

Skin contact:

May cause skin irritation.

Inhalation:

May cause respiratory tract irritation. May cause mucous membrane irritation. Neurotoxic
effects are possible. In case of dust formation: If inhaled lung damage is possible.

Ingestion:

Ingestion is not expected in industrial use.

Additional information on acute health effects:

The toxicological evaluation is based on known effects of the active ingredient(s). This
material releases ethanol upon hydrolysis. Ethanol (CAS-No. 64-17-5) is an irritant to the eyes
and mucous membranes. Overexposure has been shown to cause central nervous system depression.
Direct contact with the eyes will cause burning and stinging.

3.3 Further information:

Chronic health effects:

No known or expected chronic health effects.

Medical conditions which may be aggravated by exposure:

none known .

Target organs affected:

Lungs

Signs and Symptoms of Exposure:

Refer to Acute Health Effects, listed above.

Carcinogens/Reproductive toxins:

This material does not contain any reportable carcinogenic ingredients. This material does not
contain any reproductive toxins at or above OSHA or WHMIS reportable levels.


See Section 11 for Toxicological Information, if any.

4 First-aid measures

4.1 General information:

Get medical attention if irritation occurs or if breathing becomes difficult. Remove
contaminated clothing and shoes.
4.2 After inhalation:

If inhaled remove to fresh air. If not breathing, give artificial respiration. If breathing is

If contact with eyes, immediately hold eyelids apart and flush with plenty of water for at
least 15 min.
4.5 After swallowing:

For ingestion, if conscious, give several glasses of water but do not induce vomiting. If
vomiting does occur, give additional fluids.
4.6 Advice for the physician:

Treat symptomatically.
