Occupational Exposure limit values

NIOSH considers amitrole to be 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: 0.2 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.

10.3 Possibility of hazardous reactions

Aqueous, nonflammable, as amitrol-t; dry powder, non-flammable, as amizol.Dust explosion possible if in powder or granular form, mixed with air.AMITROLE is a triazole derivative. The triazoles are a group that contain several derivatives that are highly explosive materials. They are sensitive to heat, friction, and impact. Sensitivity varies with the type substitution to the triazole ring. Metal chelated and halogen substitution of the triazole ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives. AMITROLE forms chelates with some metals. It is corrosive to iron, copper and aluminum. Forms salts with most acids and alkalis. This compound is incompatible with strong oxidizers, strong acids, acid chlorides and acid anhydrides .

• Toxicity to daphnia and other aquatic invertebrates: EC50 Daphnia magna (Water flea; intoxication, immobilization) 30 ppm/48 hr; static /formulated product

12.2 Persistence and degradability

WHATEVER THE MECHANISM WHEREBY TRIAZOLE RING IS OPENED, THERE APPEARS TO BE LITTLE DOUBT THAT RING OPENING DOES OCCUR RAPIDLY IN SOILS & RESULTING PRODUCTS (UREA, CYANAMID, & NITROGEN) SHOULD BE READILY METABOLIZED BY SOIL MICROORGANISMS.

12.3 Bioaccumulative potential

Carp exposed to 2 and 0.2 mg/L 2-amino-1,3,4-triazole over a 6 week incubation period had reported BCF values of <0.3 and <3, respectively(1). According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Based on batch equilibrium experiments, 2-amino-1,3,4-triazole (dissolved in 1% sodium azide solutions) was determined to be mobile in silty clay, sandy loam, sand, and silt soils, with Freundlich Kf values of 0.152-0.922 ml/g(1). Freundlich Kf values were 0.714 (1/n = 0.7671) for the silty clay soil, 0.223 (1/n = 0.8549) for the sandy loam soil, 0.152 (1/n = 0.8722) for the sand soil, and 0.922 (1/n = 0.8590) for the silt soil; corresponding Koc values were 11.6, 29.7, 20.2, and 51.2, respectively(1). 2-Amino-1,3,4-triazole was mobile in these same soils when the soils were acidified to approximately pH 4.5; Freundlich Kf values ranged from 0.575-2.28. In another batch equilibrium study, 2-amino-1,3,4-triazole was determined to be mobile in Plainsfield sand (Kf = 0.685, 1/n = 0.7975), California sandy loam (Kf = 3.52, 1/n = 0.6487), Kewaunee silty clay loam (K = 1.57, 1/n = 0.8563), and Plano silt loam (Kf = 3.79, 1/n = 0.7739) soils(1). No discernible correlation between adsorption and either organic carbon content or CEC of the soils was observed(1). According to a classification scheme(2), these Koc values suggests that 2-amino-1,3,4-triazole is expected to have very high to high mobility in soil(SRC).

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.
