2-METHYL-5-ETHYLPYRIDINE

Diamond	Hazard	Value	Description
2 3 0	Health	3	Can cause serious or permanent injury.
	Flammability	2	Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
	Instability	0	Normally stable, even under fire conditions.
	Special

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.

none

Insoluble in water.

Special Hazards of Combustion Products: Irritating vapors are generated when heated (USCG, 1999)

Breathing of vapors will cause vomiting and chest discomfort. Contact with liquid causes skin and eye burns. (USCG, 1999)

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].

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

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 the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank 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, 2024)

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. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal.

FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices 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 in direct contact with flames. (ERG, 2024)

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from 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, 2024)

Air-supplied mask for high vapor concentrations; plastic gloves; goggles or face shield. (USCG, 1999)

No information available.

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)
