Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Causes severe burns.Corrosive.Water-reactive.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Causes eye burns. May cause irreversible eye injury.
Skin:
Causes severe skin irritation and burns.
Ingestion:
Causes gastrointestinal tract burns. Causes severe pain, nausea, vomiting, diarrhea, and shock.
Inhalation:
May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract. May cause pulmonary edema and severe respiratory disturbances. Harmful if inhaled.
Chronic:
Early symptoms of chronic phosphorous intoxication include gastrointestinal distress and possibly a garlic-like odor to the breath. Chronic exposure can lead to necrosis of the jaw, or 'phossy-jaw'.

Section 4 - FIRST AID MEASURES
  Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:
Antidote: None reported.

Section 5 - FIRE FIGHTING MEASURES
  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will react with water to form toxic and corrosive fumes. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Do NOT use water directly on fire. Use dry chemical, carbon dioxide, or alcohol-resistant foam. Do NOT get water inside containers. Cool containers with flooding quantities of water until well after fire is out.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Do not flush into a sewer. Wash area with soap and water. Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Provide ventilation. Do not get water on spilled substances or inside containers.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Wash hands before eating. Do not allow water to get into the container because of violent reaction. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Do not store near combustible materials.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Keep away from metals. Corrosives area. Keep containers tightly closed. Keep away from strong bases.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
Exposure Limits CAS# 1314-56-3: United Kingdom, WEL - STEL: 2 mg/m3 STEL Belgium - TWA: 1 mg/m3 VLE France - VME: 1 mg/m3 VME Germany: 1 mg/m3 TWA (inhalable fraction) Netherlands: 1 mg/m3 MAC Russia: 1 mg/m3 TWA Spain: 1 mg/m3 VLA-ED Spain: 2 mg/m3 VLA-EC Personal Protective Equipment Eyes: Wear chemical goggles and a face shield if splashing is possible. Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear butyl rubber gloves, apron, and/or clothing.
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
