Hazards and Protection.
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.
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.
The use of personal protective equipment such as glasses, synthetic gloves and face masks is important.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
(Non-Specific -- Pesticide, Solid, n.o.s.) Do not touch spilled material; stop leak if you can do it without risk. Use water spray to reduce vapors. Small spills: take up with sand or other noncombustible absorbent material and place into containers for later disposal. Small dry spills: with clean shovel place material into clean, dry container and cover; move containers from spill area. Large spills: dike far ahead of spill for later disposal. Use caution with this material.
Very stable under normal conditions. Sensitive to light. Tenoran 50 wettable powder shows no hygroscopic tendencies and can therefore be stored for long periods even in tropical climates. Decomposed by UV light. Hydrolyzed to 4-(p-chlorophenoxy)aniline in strong acids and alkalis. No significant hydrolysis occurred at 30 C at pH 1.Ultraviolet source of 300w caused 90% loss in 13 hr under controlled conditions.
(Non-Specific -- Pesticide, Solid, n.o.s.) Avoid breathing vapors or dust. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing.(Non-Specific -- Pesticide, Solid, n.o.s.) For small fires, use dry chemical, carbon dioxide, water spray, or foam. For large fires, use water spray, fog, or foam.
CNS depression and coma were produced in animals by chloroxuron. No reproductive studies were found.
Nausea, vomiting, and diarrhea may be noted following ingestion.
Irritation may occur with high inhalation exposure.
Cyanosis unresponsive to oxygen therapy may be noted in patients with methemoglobinemia due to absorption of excessive amounts of these agents.
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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.
Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
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.
