**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful in contact with skin and if swallowed. Causes
burns.Hygroscopic (absorbs moisture from the air).Corrosive.
Potential Health Effects
Eye:
Causes severe eye irritation and possible burns.
Skin:
Harmful if absorbed through the skin. Causes severe skin irritation
and possible burns.
Ingestion:
Harmful if swallowed. May cause burns to the digestive tract.
Ingestion may cause weakness, ataxia (failure of muscular
coordination), diarrhea, and unconsciousness.
Inhalation:
Causes respiratory tract irritation. May cause burns to the
respiratory tract.
Chronic:
Laboratory experiments have resulted in mutagenic effects.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
Notes to Physician:
Treat symptomatically and supportively.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. During a fire, irritating and
highly toxic gases may be generated by thermal decomposition or
combustion. Use water spray to keep fire-exposed containers cool.
Water may be ineffective. Material is lighter than water and a fire
may be spread by the use of water. Combustible liquid. Vapors may be
heavier than air. They can spread along the ground and collect in
low or confined areas. Containers may explode when heated.
Extinguishing Media:
This material is lighter than water and insoluble in water. The fire
could easily be spread by the use of water in an area where the water
cannot be contained. Do NOT get water inside containers. Cool
containers with flooding quantities of water until well after fire is
out. Use water spray, dry chemical, carbon dioxide, or appropriate
foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Use water
spray to disperse the gas/vapor. Remove all sources of ignition.
Provide ventilation. Stop leak only if you can do so without risk.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep container tightly closed. Keep away from
heat, sparks and flame. Do not get on skin or in eyes. Do not ingest
or inhale. Discard contaminated shoes. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances. Corrosives area. Store protected
from moisture. Do not store in copper or copper alloy storage
vessels.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 104-90-5:
Russia: 2 mg/m3 TWA
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure. Rubber and plastic gloves should not be
relied upon to prevent skin contact.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.

**** SECTION 12 - ECOLOGICAL INFORMATION ****
Ecotoxicity:
Fish: Fathead Minnow: 81.1 mg/L; 96 Hr.; Flow-through bioassayFish:
Fathead Minnow: 69.8 mg/L; 96 Hr.; Flow-through bioassayThe estimated
Koc range of 25-540 was calculated using the regression-derived
equation. This value suggests that 5-Ethyl-2-methyl-pyridine will be
highly mobile in soil and should not partition from the water column
to organic matter contained in sediments and suspended solids. Based
on a pKa of 6.40, this product and its conjugate acid will exist
among most environmental media in vaying proportions that are pH
dependent. The estimated log BCF values = 0.49 and 1.66. These
values indicate that 5-Ethyl-2-methyl-pyridine should not
