8.Exposure controls/personal protection

8.1 Control parameters

Occupational Exposure limit values

NIOSH recommends that captafol be regulated as a potential occupational carcinogen. NIOSH usually recommends that occupational exposures to carcinogens be limited to the lowest feasible concn.

Recommended Exposure Limit: 10 Hr Time-Weighted Avg: 0.1 mg/cu m.

Biological limit values

no data available

8.2 Appropriate engineering controls

Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

8.3 Individual protection measures, such as personal protective equipment (PPE)

Eye/face protection

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

Thermal hazards

no data available

9.Physical and chemical properties

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Slowly hydrolyzed in aqueous emulsion or suspension. Rapidly hydrolyzed in acidic and alkaline media. Decomposes slowly at the melting point.

10.3 Possibility of hazardous reactions

CAPTAFOL is non-flammable but, on heating, may decompose to generate toxic fumes, such as sulfur oxides, hydrogen sulfide, hydrochloric acid, and phosgene. Stable at room temperature when dry but readily hydrolysed, especially in an alkaline environment. Captafol and mixtures containing high concentrations of captafol may react violently with alkali. Incompatible with acids, acid chlorides, acid anhydrides, and strong oxidizing agents. Sulfhydryl compounds such as glutathione and cysteine cause a rapid chemical decomposition.

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

Incompatible with highly alkaline materials.

10.6 Hazardous decomposition products

When heated to decomposition it emits very toxic fumes of /hydrogen chloride, oxides of nitrogen and oxides of sulfur/.

Carcinogenicity

Evaluation: No data were available from studies in humans. There is sufficient evidence in experimental animals for the carcinogenicity of captafol. In making the overall evaluation, the working group took into consideration the following supporting evidence: Captafol is active in a wide range of tests for genetic and related effects, including the generally insensitive in vivo assay for dominant lethal mutation. Overall evaluation: Captafol is probably carcinogenic to humans (2A).

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

12.2 Persistence and degradability

In a laboratory incubation study with three kinds of soils under two moisture levels (field capacity and submergence) the biodegradation half-lives of difolatan ranged 23-55 days(1). The overall half-life of difolatan in soil is about 11 days, independent of soil type or initial concn(2). In soil, difolatan may be initially inhibitive to certain bacterial and microbial populations, but may be stimulative to certain bacterial populations(3,4). The inhibitory effect disappears in 7 days at a treatment level of 10 ppm(4). The rate of biodegradation was slowest in soil containing the highest organic carbon content(1,5).

12.3 Bioaccumulative potential

An estimated BCF of 170 was calculated for difolatan(SRC), using a log Kow of 3.80(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not altered physically or chemically after being released to the environment.

12.4 Mobility in soil

The adsorption coefficient, logKom, for difolatan based on soil organic matter has been reported as 3.08(1) and 3.09(2). Based on a relationship Kom = Koc/1.724(3), the Koc for difolatan would be 2073 and 2120, respectively. According to a classification scheme(4), these Koc values suggests that difolatan is expected to be slightly mobile in soil.

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.
