Chemical Identifiers

The Chemical Identifier fields include common identification numbers, the NFPA diamond, U.S. Department of Transportation hazard labels, and a general description of the chemical. The information in CAMEO Chemicals comes from a variety of data sources.
CAS Number UN/NA Number DOT Hazard Label USCG CHRIS Code
  • 104-90-5   (2-METHYL-5-ETHYLPYRIDINE)
  • Poison
NIOSH Pocket Guide International Chem Safety Card
none none
NFPA 704
Diamond Hazard Value Description
2
3 0
Blue Health 3 Can cause serious or permanent injury.
Red Flammability 2 Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
Yellow Instability 0 Normally stable, even under fire conditions.
White Special
(NFPA, 2010)
General Description
A colorless to yellow liquid. Insoluble in water and more dense than water. Hence sinks in water. Contact may slightly irritate the skin, eyes, and mucous membranes. May be toxic by ingestion. Used to make other chemicals.

Hazards

The Hazard fields include special hazard alerts, air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
none
Air & Water Reactions
Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: Irritating vapors are generated when heated (USCG, 1999)
Health Hazard
Breathing of vapors will cause vomiting and chest discomfort. Contact with liquid causes skin and eye burns. (USCG, 1999)
Reactivity Profile
2-METHYL-5-ETHYLPYRIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. A mixture of nitric acid and methyl ethyl pyridine was placed in an autoclave and heated and stirred for 40 minutes. The emergency vent opened due to a sudden pressure rise, then an explosion occurred after about 90 seconds [Chem. Eng. News 30:3348. 1952].

Response Recommendations

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)
Firefighting
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

SMALL FIRE: Dry chemical, CO2 or water spray.

LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
Non-Fire Response
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2016)
Protective Clothing
Air-supplied mask for high vapor concentrations; plastic gloves; goggles or face shield. (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
INHALATION: remove victim to fresh air; give oxygen if breathing is difficult; call a physician.

SKIN OR EYES: immediately flush with plenty of water for at least 15 min.; get medical care for eyes. (USCG, 1999)
