3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: Hazardous chemical. Clear amber liquid. Phenoxy odor. May cause irreversible
eye damage seen as corneal opacity. Emergency personnel should wear a self contained breathing apparatus
because noxious fumes are produced under fire conditions.
Potential Health Effects: This section includes possible adverse effects which could occur if this material is not
handled in the recommended manner.
Eye: May cause irritation with corneal opacity.
Skin: Prolonged or frequent skin exposure may cause skin irritation.
Ingestion: Harmful if swallowed. Ingestion may cause nausea, vomiting, abdominal pain, mytonia, muscle
weakness, and fall in blood pressure.
Inhalation: Expected to be harmful. May cause irritation to the respiratory tract, caughing annd dizziness. Avoid
breathing vapors or mist.

Physical Properties
Appearance: Clear amber liquid.
Odor: Penoxy.
4. FIRST AID MEASURES
Ingestion: Do not induce vomiting. Contact a physician or poison control center immediately.
Eye Contact: Flush eyes with water immediately and continuously for 15 minutes. Consult a
physician.
Skin Contact: Wash skin with plenty of soap and water for 15 minutes. Remove contaminated clothing and
wash before reuse. Consult a physician if irritation develops.
Inhalation: Remove to fresh air. Consult a physician if irritation develops of breathing is difficult.
Medical Condition Likely to be Aggravated by Exposure: Skin irritation may be aggravated in persons with existing skin
lesions. Breathing of vapors may aggravate conditions such as asthma, emphysema or chronic bronchitis.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
These precautions are suggested for conditions with a high potential for exposure. If handling procedures are such
that there is only a low potential for exposure, less protection may be needed. Emergency conditions may require
additional precautions.
Engineering Controls: Normal room ventilator should be satisfactory. Eyewash stations and safety showers
should be easily accessible.
Eye Contact: Use chemical goggles. Eye wash station should be located in the immediate work area.
Skin Contact: Use protective clothing impervious to this material.
Inhalation: Use a NIOSH approved respirator when protection is required.
