Hazard Codes of Propyl chloride (CAS NO.540-54-5): FlammableF,HarmfulXn
Risk Statements: 11-20/21/22 
R11: Highly flammable. 
R20/21/22: Harmful by inhalation, in contact with skin and if swallowed.
Safety Statements: 9-29 
S9: Keep container in a well-ventilated place.

RIDADR: UN 1278 3/PG 2
WGK Germany: 3
RTECS: TX4400000
HazardClass: 3.1
PackingGroup: II
A moderately poisonous irritant to skin, eyes, and mucous membranes. Narcotic in high concentrations. Flammable liquid and dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderately explosive when exposed to flame. Keep away from heat and open flame; can react vigorously with oxidizing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits toxic fumes of Cl. See also CHLORINATED HYDROCARBONS, ALIPHATIC.

1-Chloropropane Standards and Recommendations

DOT Classification:  3; Label: Flammable Liquid

1-Chloropropane Specification

1. Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
2. Handling: Wash thoroughly after handling. Use only in a well ventilated area. Ground and bond containers when transferring material. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
3. Personal Protection: 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. Clothing: Wear appropriate protective clothing to prevent skin exposure.
4. Fire Fighting: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide.
5. Reactivity Profile: 1-Chloropropane presents a dangerous fire risk. May be incompatible with strong oxidizing and reducing agents. Incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
