First Aid Measures

Ingestion

Rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal .

Inhalation

Establish a patient airway. Suction if necessaryAggressive airway control may be needed. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary. Monitor for shock and treat if necessary Anticipate seizures and treat if necessary .

Skin

Flush exposed area with water, wash with soap and water. Monitor for symptoms.

Eyes

Flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport to medical facility

Handling and Storage

Storage

Keep tightly closed. Store at 2-8 C

Hazards Identification

Inhalation

Profenofos can cause cholinesterase inhibition in humans; that is, it can stimulate the nervous system causing nausea, dizziness, confusion and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.

Skin

See inhalation.

Eyes

See inhalation.

Ingestion

See inhalation.

Hazards

Emits toxic fumes under fire conditions.

Exposure Controls/Personal Protection

Personal Protection

Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves.

Respirators

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

Exposure Effects

Harmful by inhalation, in contact with skin and if swallowed. Readily absorbed through skin. Target organ(s): Blood. Heart.

Poison Class

3

Fire Fighting Measures

Flash Point

197

Fire Fighting

Extinguish using Carbon dioxide, dry chemical powder, or appropriate foam. Water spray. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Fire Potential

Combustible material: may burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks

Absorb on sand or vermiculite and place in closed containers for disposal. Ventilate area and wash spill site after material pickup is complete.

Stability and Reactivity

Incompatibilities

Alkaline conditions. Oxidizing and reducing agents.

Stability

Stable under normal temperatures and pressures.

Decomposition

Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Combustion Products

Sulfur oxides, phosphorus oxides, hydrogen bromide and hydrogen chloride.
