SECTION 4: First aid measures

Description of necessary first-aid measures

If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.

Following skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Following eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

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)

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

Absorption, Distribution and Excretion

Both compounds /SAN-6706 and norflurazon/ were readily absorbed from nutrient solution by cotton (Gossypium hirsutum Leguminatae "Coker 203"), corn (Zea mays Leguminatae "WF9") and soybean (Glycine max (Leguminatae) Merr. "Lee") plants. In corn and soybean plants, these compounds were translocated more rapidly and in greater amount than in cotton.

SECTION 5: Firefighting measures

Suitable extinguishing media

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

Specific hazards arising from the chemical

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. For UN3508, be aware of possible short circuiting as this product is transported in a charged state. (ERG, 2016)

Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

Persistence and degradability

AEROBIC: Norflurazon degrades slowly in aerobic soil, with a reported half-life of 130 days(1). The biodegradation half-life under aquatic conditions is 6-8 months(1). It has been found that biodegradation in soil is influenced by environmental conditions, with the rate increasing with increasing depth (5 cm, half-life 100 days; 80 cm, half-life 260 days), increasing with increasing pH (pH 5.25, half-life 105 days; pH 7.0, half-life 225 days), and decreasing with increasing soil organic matter (0.75% OM, half-life 210 days; 2.20% OM, half-life 75 days)(2). The soil types used in this study were a Lexington silt loam (Tennessee), a Beulah silt loam (Mississippi), and a Dothan loamy sand (Georgia)(2).

Bioaccumulative potential

An estimated BCF of 12 was calculated in fish for norflurazon(SRC), using a log Kow of 2.30(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).

Mobility in soil

The Koc of norflurazon is estimated as 420(SRC), using a log Kow of 2.30(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that norflurazon is expected to have moderate mobility in soil. Binding does appear to be influenced by organic matter, clay content and cation exchange capacity(4). Koc values of 3,311(5) and 1,914(6) have been reported for norflurazon although it is generally observed that norflurazon is expected to be mobile to highly mobile in soil(7).

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. 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.
