SECTION 4: First aid measures

Description of necessary first-aid measures

If inhaled

Fresh air, rest.

Following skin contact

Remove contaminated clothes. Rinse and then wash skin with water and soap.

Following eye contact

Rinse with plenty of water for several minutes (remove contact lenses if easily possible).

Following ingestion

Rinse mouth.

Most important symptoms/effects, acute and delayed

Inhalation may cause nausea because of disagreeable odor. Contact of liquid with eyes causes mild irritation. Prolonged exposure of skin to liquid causes reddening and irritation. Ingestion produces nausea. (USCG, 1999)

Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Ethers and related compounds

Persistence and degradability

AEROBIC: In a river die-away test using Ohio River water with weekly additions of settled sewage inoculum (1% by volume), diphenyl ether's theoretical CO2 evolution was found to be only 20% after 75 days of incubation(1); re-dosing tests found that diphenyl ether was oxidized slightly better after re-dosing(1); however, the overall test results indicated that diphenyl ether was resistant to biological action(1). Diphenyl ether, present at 100 mg/L, reached 6.3% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test and is considered not readily biodegradable(2). Using a die-away study with spiked soil and sludge, diphenyl ether dissipated to below detectable levels after 3 months, loss processes were not confirmed and may have included volatilization and adsorption(3).

Bioaccumulative potential

Using a 4-day exposure period, a diphenyl ether steady-state BCF of 195 was measured in rainbow trout (Salmo gairdneri)(1). A steady-state BCF of 470 has also been reported for rainbow trout after 7 day exposure period at 16 ug/L(2). Using a 4-day exposure period a BCF of 590 was measured in rainbow trout(3). BCF ranges of 112-583 and 49-594 were calculated using carp (Cyprinus carpio) which were exposed to 0.3 and 0.03 ppm, respectively, over an 8-week period(4). According to a classification scheme(5), these data suggest that bioconcentration in aquatic organisms is moderate to high(SRC).

Mobility in soil

A Koc of 1950 for diphenyl ether can be determined(SRC) from a measured soil/water partition coefficient (Kd) of 12.4 in an Australian soil (organic matter content of 1.09%)(1). A log Koc of 3.29 has been reported(2), corresponding to a Koc of 1949(SRC). According to a classification scheme(3), these Koc values suggest that diphenyl ether is expected to have low mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods

Product

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.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning.
