SECTION 5: Firefighting measures
Suitable extinguishing media
If material on fire or involved in fire: Use water in flooding quantities as fog. Solid streams of water may be ineffective Use "alcohol" foam, dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. Do not extinguish fire unless flow can be stopped. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources.
Specific hazards arising from the chemical
Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
Special protective actions for fire-fighters
Use foam, dry powder, carbon dioxide. NO water. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures

SECTION 10: Stability and reactivity
Reactivity
The substance can presumably form explosive peroxides. Decomposes on burning. This produces toxic gases and irritating fumes.
Chemical stability
Highly volatile
Possibility of hazardous reactions
EXTREMELY FLAMMABLE.The vapour is heavier than air and may travel along the ground; distant ignition possible.Ethers, such as DIPROPYL ETHER, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
Conditions to avoid
no data available
Incompatible materials
The substance can presumably form explosive peroxides. The substance decomposes on burning producing toxic /emissions/ and irritating fumes.
Hazardous decomposition products
When heated to decomposition it emits acrid smoke and irritating fumes.

Persistence and degradability
AEROBIC: An activated sludge aqueous screening study found that dipropyl ether was biodegraded quickly after a 13 day lag period with a 63% theoretical biological oxygen demand being measured after 25 days incubation(1). In another activated sludge screening test dipropyl ether was not biodegraded within 240 hours(2). Many ethers are known to be resistant to biodegradation(3).
Bioaccumulative potential
An estimated BCF of 7 was calculated for dipropyl ether(SRC), using a log Kow of 2.03(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for dipropyl ether can be estimated to be about 15(SRC). According to a classification scheme(2), this estimated Koc value suggests that dipropyl ether is expected to have very high mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
