4. FIRST AID MEASURES
FIRST AID MEASURES FOR ACCIDENTAL:
Eye Exposure:
In case of contact, immediately absorb excess with clean absorbent cloth or cotton. Then, hold eyelids open and flush with a
steady, gentle stream of water for at least 15 minutes. Seek medical attention if irritation develops or persists or if visual
changes occur.
Skin Exposure:
Immediately wipe excess material off skin with a dry cloth; then wash skin with plenty of soap and water. Seek medical
attention if irritation develops or persists.
Inhalation:
Inhalation is not an expected route of exposure. If respiratory irritation or distress occurs remove victim to fresh air. Seek
medical attention if respiratory irritation or distress continues.
Ingestion:
If victim is conscious and alert, give 1-2 glasses of water to drink. Do not give anything by mouth to an unconscious person.
Seek medical attention. Do not leave victim unattended.
MEDICAL CONDITIONS POSSIBLY AGGRAVATED BY EXPOSURE:
No specific information found.
NOTES TO PHYSICIAN:
All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should be given to

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Introductory Remarks:
These recommendations provide general guidance for handling this product. Because specific work environments and material
handling practices vary, safety procedures should be developed for each intended application. While developing safe handling
procedures, do not overlook the need to clean equipment and piping systems for maintenance and repairs. Waste resulting
from these procedures should be handled in accordance with Section 13: Disposal Considerations.
Assistance with selection, use and maintenance of worker protection equipment is generally available from equipment
manufacturers.

This product can form formaldehyde vapors when heated to temperatures above 150 degrees C in the presence of air.
Formaldehyde is a potential cancer hazard, a known skin and respiratory sensitizer, and an irritant to the eyes, nose, throat,
skin, and digestive system. Safe handling conditions may be maintained by keeping vapor concentrations within the OSHA
Permissible Exposure Limit for formaldehyde.
Exposure Guidelines:
No exposure limits were found for this product or any of its ingredients.
Engineering Controls:
Where engineering controls are indicated by use conditions or a potential for excessive exposure exists, the following
traditional exposure control techniques may be used to effectively minimize employee exposures: general area
dilution/exhaust ventilation.
Respiratory Protection:
When respirators are required, select NIOSH/MSHA approved equipment based on actual or potential airborne concentrations
and in accordance with the appropriate regulatory standards and/or industrial recommendations.
For reasonably foreseeable industrial end uses of this material, respiratory protection should not be necessary.
Eye/Face Protection:
Eye and face protection requirements will vary dependent upon work environment conditions and material handling practices.
Appropriate ANSI Z87 approved equipment should be selected for the particular use intended for this material.
It is generally regarded as good practice to wear a minimum of safety glasses with side shields when working in industrial
environments.
Skin Protection:
Skin contact should be minimized through use of gloves and suitable long-sleeved clothing (i.e., shirts and pants).
Consideration must be given both to durability as well as permeation resistance.
Work Practice Controls:
Personal hygiene is an important work practice exposure control measure and the following general measures should be taken
when working with or handling this material:
(1) Do not store, use, and/or consume foods, beverages, tobacco products, or cosmetics in areas where this
material is stored.
(2) Wash hands and face carefully before eating, drinking, using tobacco, applying cosmetics, or using the toilet.
