4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest.

In case of skin contact

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

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Give one or two glasses of water to drink.

4.2 Most important symptoms/effects, acute and delayed

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)

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

Skin contamination should be treated promptly by washing with soap and water. Contamination of the eyes should be treated immediately by prolonged flushing of the eyes with large amounts of clean water. If dermal or ocular irritation persists, medical attention should be obtained without delay. /Other Herbicides/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Extinguish fire using agent suitable for type of surrounding fire. Material itself does not burn or burns with difficulty. /Carbaryl (agricultural insecticides, nec, liquid); Carbaryl (agricultural insecticides, nec, other than liquid); Carbaryl (insecticides, other than agricultural, nec/

5.2 Specific hazards arising from the chemical

Flash point data for this chemical are not available, however it is probably combustible.

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers.

6.3 Methods and materials for containment and cleaning up

A system for removing pesticides from the wash water produced by pesticide applicators as they clean their equipment has been developed. The first step is the flocculation/coagulation and sedimentation of the pesticide-contaminated wash water. The supernatant from the first step is then passed through activated carbon columns. /Pesticides/

no data available

10.2 Chemical stability

Unlimited shelf life; not light or heat sensitive, but low temperature may cause crystallization of emulsifiable concentrate.

10.3 Possibility of hazardous reactions

ISOPROPYL-N-(3-CHLOROPHENYL)CARBAMATE is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

no data available

10.5 Incompatible materials

no data available

  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available

12.2 Persistence and degradability

SOIL MICROORGANISMS READILY DEGRADE CHLORPROPHAM ... BY PRODN OF 3-CHLOROANILINE BY ENZYMATIC HYDROLYSIS REACTION WITH SUBSEQUENT LIBERATION OF FREE CHLORIDE ION & CARBON DIOXIDE. ... PSEUDOMONAS STRIATA CHESTER, A FLAVOBACTERIUM SP, AN AGROBACTERIUM SP, & ACHROMOBACTER SP /DEGRADE IT/. ... BIOASSAY TESTS INDICATE HALF LIFE OF CHLORPROPHAM TO BE ABOUT 65 DAYS @ 15 DEG C & 30 DAYS @ 29 DEG C. HOWEVER, RATE OF DISSIPATION CAN VARY GREATLY WITH MICROBIAL ACTIVITY & MOISTURE LEVEL OF GIVEN SOIL.

12.3 Bioaccumulative potential

An estimated BCF of 100 was calculated for chlorpropham(SRC), using a log Kow of 3.51(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

Koc values for chlorpropham ranging from 245 to 816 have been reported(1-4). According to a classification scheme(5), these Koc values suggest that chlorpropham is expected to have moderate to low mobility in soil. Leaching of chlorpropham from three different types of soil was low(6). More than 90% of recovered chlorpropham was found in the upper inch of the soil profile after 4 cm of rain(6). Very little chlorpropham adsorbs to montmorillonite or kalonite clay(7).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 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. 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.
