8.Exposure controls/personal protection

8.1 Control parameters

Occupational Exposure limit values

NIOSH (NOES Survey 1981-1983) has statistically estimated that 2,132 workers (1,796 of these are female) are potentially exposed to 1-naphthylamine in the US(1). The NOES Survey does not include farm workers. Occupational exposure to 1-naphthylamine may occur through inhalation and dermal contact with this compound at workplaces where 1-naphthylamine is produced or used. Monitoring data indicate that the general population may be exposed to 1-naphthylamine via contact with contaminated surface or groundwaters or by inhalation of cigarette smoke(SRC).

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.

Respiratory protection

Wear dust mask when handling large quantities.

12.2 Persistence and degradability

AEROBIC: Using activated sludge from both domestic and industrial sources and the Warburg technique, 1-naphthylamine depletion after 6 hrs at 25°C was measured to be 80-84% from an initial concn of 20 ppm(1). 1-Naphthylamine, at a concn of 500 ppm, was extensively oxidized by an aniline-acclimated activated sludge after 19 hrs in a Warburg respirometer(2). Over a 20-day period, no biodegradation of 200 ppm 1-naphthylamine as a sole carbon source was observed in a batch system containing an adapted activated sludge(3). 1-Naphthylamine at 500 ppm was found to inhibit oxygen uptake in a Warburg respirometer containing a municipal activated sludge(4). At 1000 ppm, 1-naphthylamine was toxic to an activated sludge(5). 1-Naphthylamine degradation in six different soils after 308 days of incubation at 23°C varied from 16.6-30.7% as measured by radio-labelled carbon dioxide evolution(6). Comparison of carbon dioxide evolution in sterilized (via gamma radiation) versus unsterilized soil suggested that the degradation was predominantly microbial in nature(6). Approximately 16, 28 and 33% of added 1-naphthylamine degraded in Russell soil at temperatures of 12, 23 and 30°C, respectively, indicating the effect of temperature on microbial degradation(6).

12.3 Bioaccumulative potential

An estimated BCF of 11 was calculated for 1-naphthylamine(SRC), using a log Kow of 2.25(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(SRC), provided the compound is not altered physically or chemically once released into the environment.

12.4 Mobility in soil

Using a batch equilibrium technique, 1-naphthylamine Koc values of 2,688 and 3,173 were determined for two sandy-silt soils and a Koc value of 3,777 was determined for a silty-clay soil(1). According to a classification scheme(2), this estimated Koc value suggests that 1-naphthylamine is expected to have low mobility in soil. Results of a batch equilibrium study with various soils indicated that 1-naphthylamine binds to soil in two phases with an initial rapid and reversible equilibrium established between the amine and the inorganic and organic components of soil followed subsequently by a strong association with the humic fraction of soil via covalent binding(3,4). In laboratory study, 1-naphthyalmine was found to have a relatively moderate tendency to adsorb to lignite coal in subsurface areas where it may be present as a contaminant from coal-gasification plants(5).

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.
