4. FIRST AID MEASURES-----------Up to Table of Contents

INHALATION:

Remove from exposure immediately. Use a bag valve mask or similar device to perform artificial

respiration (rescue breathing) if needed. Get medical attention.



SKIN CONTACT:

Remove contaminated clothing, jewelry, and shoes immediately. Wash with soap or mild

detergent and large amounts of water until no evidence of chemical remains (at least 15-20

minutes). Get medical attention, if needed.



EYE CONTACT:

Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper

and lower lids, until no evidence of chemical remains. Get medical attention immediately.



INGESTION:

Contact local poison control center or physician immediately. Never make an unconscious person

vomit or drink fluids. When vomiting occurs, keep head lower than hips to help prevent aspiration.

If person is unconscious, turn head to side. Get medical attention immediately.



NOTE TO PHYSICIAN:

For ingestion, consider gastric lavage.

5. FIRE FIGHTING MEASURES-----------Up to Table of Contents



FIRE AND EXPLOSION HAZARDS:

Severe fire hazard. Vapor/air mixtures are explosive above flash point. The vapor is heavier than

air. Vapors or gases may ignite at distant ignition sources and flash back.



EXTINGUISHING MEDIA:

regular dry chemical, carbon dioxide, water, regular foam



Large fires: Use regular foam or flood with fine water spray.



FIRE FIGHTING:

Move container from fire area if it can be done without risk. Cool containers with water spray until

well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool

containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If

this is impossible then take the following precautions: Keep unnecessary people away, isolate

hazard area and deny entry. Let the fire burn. Withdraw immediately in case of rising sound from

venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank truck:

Evacuation radius: 800 meters (1/2 mile). Water may be ineffective.



FLASH POINT:

55 F (13 C) (CC)



LOWER FLAMMABLE LIMIT:

1.0%



UPPER FLAMMABLE LIMIT:

6.5%



AUTOIGNITION:

403 F (206 C)



FLAMMABILITY CLASS (OSHA):

IB





6. ACCIDENTAL RELEASE MEASURES-----------Up to Table of Contents



OCCUPATIONAL RELEASE:

Avoid heat, flames, sparks and other sources of ignition. Stop leak if possible without personal

risk. Reduce vapors with water spray. Small spills: Absorb with sand or other non-combustible

material. Collect spilled material in appropriate container for disposal. Large spills: Dike for later

disposal. Remove sources of ignition. Keep unnecessary people away, isolate hazard area and

deny entry.





7. HANDLING AND STORAGE-----------Up to Table of Contents



Store and handle in accordance with all current regulations and standards.
