Repeated exposure to an highly toxic material may produce general deterioration of health by an accumulation in
one or many human organs.
Meperidine HCl

Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention.
Skin ContactAfter contact with skin, wash immediately with plenty of water. Gently and 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 ContactNot available.
InhalationAllow the victim to rest in a well ventilated area. Seek immediate medical attention.
Serious InhalationEvacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Seek medical attention.
IngestionDo not induce vomiting. 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. 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.

Section 6. Accidental Release Measures
Small SpillUse appropriate tools to put the spilled solid in a convenient waste disposal container.
Large SpillUse a shovel to put the material into a convenient waste disposal container.
Meperidine HCl

Section 7. Handling and Storage
PrecautionsKeep locked up Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk,
evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not
breathe dust. Avoid contact with eyes Wear suitable protective clothing In case of insufficient ventilation, wear
suitable respiratory equipment If ingested, seek medical advice immediately and show the container or the label.
StorageKeep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly
closed. Keep in a cool, well-ventilated place. Highly toxic or infectious materials should be stored in a separate
locked safety storage cabinet or room.

Section 8. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal ProtectionSplash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
a Large Spillto avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
