SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 127 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
Wash skin with soap and water.
In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin.
Keep victim warm and quiet.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

FIRST AID

FIRST AID

EYE EXPOSURE - Immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical.
DERMAL EXPOSURE - Immediately wash the contaminated skin with soap and water. If this chemical penetrates the clothing, immediately remove the clothing, wash the skin with soap and water, and get medical attention promptly.
INHALATION EXPOSURE - Move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.
ORAL EXPOSURE - If this chemical has been swallowed, get medical attention immediately.
TARGET ORGANS - Eyes, skin, and respiratory system (National Institute for Occupational Safety and Health, 2007).

GENERAL

Move victims of inhalation exposure from the toxic environment and administer 100% humidified supplemental oxygen with assisted ventilation as required. Exposed skin and eyes should be copiously flushed with water. Because of the potential for rapid onset of CNS depression or seizures with possible aspiration of gastric contents, EMESIS SHOULD NOT BE INDUCED. Cautious gastric lavage followed by administration of activated charcoal may be of benefit if the patient is seen soon after the exposure.

INHALATION EXPOSURE

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.
If bronchospasm and wheezing occur, consider treatment with inhaled sympathomimetic agents.

DERMAL EXPOSURE

DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999).
Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

EYE EXPOSURE

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

ORAL EXPOSURE

Because of the potential for gastrointestinal tract irritation or CNS depression, DO NOT induce emesis.
Significant esophageal or gastrointestinal tract irritation or burns may occur following ingestion. The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation.
GASTRIC LAVAGE: Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in the head down left lateral decubitus position or by endotracheal intubation. Control any seizures first.

CONTRAINDICATIONS: Loss of airway protective reflexes or decreased level of consciousness in unintubated patients; following ingestion of corrosives; hydrocarbons (high aspiration potential); patients at risk of hemorrhage or gastrointestinal perforation; and trivial or non-toxic ingestion.

ACTIVATED CHARCOAL: Administer charcoal as a slurry (240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old.
Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury.

CONTAINMENT/WASTE TREATMENT OPTIONS

SUMMARY

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 127 (ERG, 2004)
- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
- All equipment used when handling the product must be grounded.
- Do not touch or walk through spilled material.
- Stop leak if you can do it without risk.
- Prevent entry into waterways, sewers, basements or confined areas.
- A vapor suppressing foam may be used to reduce vapors.
- Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
- Use clean non-sparking tools to collect absorbed material.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 127 (ERG, 2004)
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Structural firefighters' protective clothing will only provide limited protection.
Attempt to stop any leaks if it will not be a hazard to personnel, and prevent the compound from entering water supplies (AAR, 1996). Absorb liquids in materials such as dry sand, earth, or vermiculite and deposit in sealed containers (Sittig, 1991).
LAND SPILL: Dig a holding area to contain liquid or solid material and build dikes to contain any surface flow using sand bags, soil, foamed polyurethane, or foamed concrete. Cement powder, fly ash, or commercial sorbents should be used to absorb the liquid (AAR, 1996).
WATER SPILL: Travel of the spill should be controlled using natural barriers or oil spill control booms. Use suction hoses to remove trapped material (AAR, 1996).

LARGE LEAK/SPILL

LARGE SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 127 (ERG, 2004)
- Dike far ahead of liquid spill for later disposal.
- Water spray may reduce vapor; but may not prevent ignition in closed spaces.

WASTE TREATMENT OPTIONS

PHYSICAL TREATMENT

Incineration is the suggested disposal method (Sittig, 1991).
Waste management activities associated with material disposition are unique to individual situations. Proper waste characterization and decisions regarding waste management should be coordinated with the appropriate local, state, or federal authorities to ensure compliance with all applicable rules and regulations.
