Toxicological Data on Ingredients: Propylene oxide: ORAL (LD50): Acute: 380 mg/kg [Rat]. 440 mg/kg [Mouse]. DERMAL (LD50): Acute: 1500 mg/kg [Rabbit]. VAPOR (LC50): Acute: 4000 ppm 4 hours [Rat].
Potential Acute Health Effects:
Eyes: Very Hazardous in case of eye contact, vapors and liquid may cause severe eye irritation with redness, tearing, burning, swelling of the conjunctiva and corneal burns. Damage may be permanent.
Skin: Hazardous in case of skin contact (irritant/permeator). Contact may cause severe irritation with redness, pain and severe burns or blisters. Propylene oxide may be absorbed through the skin in harmful amounts causing systemic effects similar to those listed under ingestion and inhalation. Propylene oxide is a skin sensitizer and may cause an allergic skin reaction. Dilute solutions may be more irritating than undiluted materials.
Ingestion: Swallowing may cause severe burns to the mouth, throat and stomach with nausea, vomiting and diarrhea. May cause central nervous system depression with headache, dizziness, drowsiness, drunkenness and collapse. May be fatal due to respiratory failure. Aspiration may occur during swallowing or vomiting resulting in lung damage.
Inhalation: Inhalation of vapors or mists may cause mucous membrane or upper respiratory tract irritation with central nervous system depression. Symptoms include headaches, dizziness, coughing, narcosis, drunkenness, incoordination, nausea, vomiting, and collapse. High vapor concentrations may cause unconsciousness, coma or death.
Potential Chronic Health Effects:
General Effects: Very hazardous in case of eye contact (irritant), of ingestion, of inhalation. Hazardous in case of skin contact (irritant permeator), Skin: Prolonged or repeated exposure may cause delayed secondary burns, ulcers or superficial scarring. Inhalation: Studies with animals have shown chronic effects such as growth depression, lung and slight liver injury. Ingestion: Studies with animals have shown chronic effects such as loss of body weight, gastric irritation and slight liver injury.
CARCINOGENIC EFFECTS: Classified 2 (Reasonably anticipated.) by NTP.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available. The substance is toxic to lungs, mucous membranes. Repeated or prolonged exposure to the substance can produce target organs damage.
Eye Contact:
Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes, keep eyelids open. Cold water may be used. Do not use an eye ointment. Get medical attention.
Skin Contact:
After contact with skin, wash immediately with plenty of water. Gently an thoroughly wash the contaminated skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cold water may be used. Cover the irritated skin with an emollient. If irritation persists, seek medical attention. Wash contaminated clothing before reusing.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical attention.
Inhalation:
Allow the victim to rest in a well ventilated area. Seek Immediate medical attention.
Serious Inhalation: Not available
Ingestion:
Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic material was ingested; the absence of such signs, however, is not conclusive.
If patient is conscious and responsive, give 4 – 8 ounces of water or milk to dilute. Do not induce vomiting (high risk of respiratory damage). If vomiting occurs, Keep head lower than hips to avoid aspiration. Loosen tight clothing such as a collar, tie, belt, or waistband. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention.
Serious Ingestion: Not available
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Persons with pre-existing skin, kidney, liver and respiratory disorders may be at increased risk from exposure to this substance.
NOTE TO PHYSICIANS:. Propylene oxide is an irritant that may cause coughing, dyspnea, noncardiogenic pulmonary edema, or chemical pneumonitis. Cyanosis has occurred. Lung injury has been observed in experimental animals. Respiratory effects may be delayed. Evaluate for respiratory distress. Consider oxygen administration. If a chemical burn is present, decontaminate skin and treat as any thermal burn. No specific antidote is known, however, consider gastric lavage and administration of a charcoal slurry.

Special Remarks on Explosion Hazards:
Propylene oxide vapors are heavier than air and may travel long distances to sources of ignition and flashback. Vapor-air mixtures are explosive above the flashpoint. May polymerize violently if involved in a fire.
Small Spill:
Dilute with water an mop up, or absorb with an inert dry material and place in an appropriate waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements
Large Spill:
Flammable liquid. Keep away from heat. Keep away from sources of ignition. Stop leak if without risk. Blanket spill area with water fog or alcohol foam to reduce vapors. Contain and recover liquid if possible. Use non-sparking tools and
equipment. Absorb with DRY earth, sand or other non-combustible material. Do not touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources. Call for assistance on disposal. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities. It is mandatory to call the National Response Center (800-424-8802) if 100 pounds (45.4 kg) or more are spilled or released to the environment.
Precautions:
Keep locked up. Keep away from heat. Keep away from sparks. Keep away from sources of ignition. Take precautionary measures against electrostatic discharges. Ground the container while dispensing. Ground all equipment containing material. Ground and bond containers, when transferring material. Use spark proof tools. Practice safe work place hygiene. Do not eat or drink near hazardous chemicals. Do not ingest. Do not breathe gas/fumes/vapor/spray. Avoid contact with skin and eyes. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment. Wash hands with soap and water after working with material. If ingested, seek medical advice immediately and show the container or the label. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
