ingestion and intravenous routes.
Moderately toxic by skin contact. Human
systemic effects: respiratory depression.
Questionable carcinogen with experimental
neoplastigenic data. Mutation data reported. |
| Potential Exposure | People engaged in the manufacture,
formulation, and application of this plant growth regulator
said to be effective for cereal grains, tomatoes, and
peppers. |
| First aid | If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin,remove contaminated clothing and wash immediately withsoap and water. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit. Medical observation isrecommended for 24-48 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for pulmonaryedema, a doctor or authorized paramedic may consideradministering a corticosteroid spray. |
| storage | Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with chlormequat chloride you should be trained on its proper handlingand storage. Keep away from strong oxidizers. Store in acool, dry place and protect from heat and moisture. Sourcesof ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in amanner that could create a potential fire or explosionhazard. |
| Shipping | UN2811 Toxic solids, organic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required. |
| Incompatibilities | Chlormequat chloride decomposes on
heating or in fire forming nitrogen oxides, carbon monoxide, and hydrogen chloride fumes. This chemical decomposes on heating with strong aqueous alkali solutions
forming trimethylamine and other gaseous products.
Contact with strong oxidizers may cause fire and explosions. Attacks many metals in presence of water. |
| Waste Disposal | Incinerate in a unit with effluent gas scrubbing. |
