First Aid Measures

Ingestion

Ipecac induced vomiting is not recommended because there is so little information about the effects of overdose in humans. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). If persons exposed to triazines exhibit symptoms of severe toxicosis, concurrent absorption of other or additional toxins should be considered.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.

Eyes

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed.

Skin

Avoid any skin contact. See Inhalation.

Eyes

See Inhalation.

Exposure Controls/Personal Protection

Personal Protection

The use of personal protective equipment such as glasses, synthetic gloves and NIOSH approved breathing apparatus is important.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Coma was reported following ingestion of an herbicide containing atrazine, aminotriazole, ethylene glycol, and formaldehyde. Muscle tremors, tetany, and ataxia have been reported in animals following ingestions of triazine herbicides.

Fire Fighting Measures

Flash Point

196

Fire Fighting

Extinguish fire using agent suitable for type of surrounding fire. Use water in flooding quantities as fog. Use alcohol foam. Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. Keep upwind.

Fire Potential

Nonflammable.

Accidental Release Measures

Small spills/leaks

Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.

Stability and Reactivity

Stability

Stable under normal conditions. The methylthio group is hydrolized in the presence of strong acids or alkalis. Estimated shelf life of 80w formulation @ least 5 yr, with only slight sensitivity to natural light and extreme temperature which would occur normally.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
