3. HAZARDS IDENTIFICATION
Burns of the esophagus and less commonly the stomach may occur after caustic ingestion,the absence of oral mucosal injury does not reliably exclude esophageal burns.Patients with stridor,drooling or vomiting are more likely to have esophageal burns.
Stridor,dyspnea,upper airway injury,and pulmonary edema,especially following inhalation of vaporized caustics,may occur.
Severe skin irritation and/or burns may occur.
Oxides from metallic fires are a serve health hazard.
Fire may produce irritating,corrosive and / or toxic gases.
4. FIRST AID MEASURES
Mucosal if no respiratory compromise is present,dilute immediately with milk or water ,mo more than 8 ounces in adults and 4 ounces in children .Gastric ipecac contraindicated of a small,flexible nasogastric or orogastric tube to suction gastric contents after recent large ingestions,the risk of further mucosal injury must be weighed against potential benefits.
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 beta2 agonist and corticosteroid aerosols.
4.3 Skin Contact
Remove contaminated clothes.Irrigate exposed skin with copious amounts of water for at least 15 minutes or longer ,depending on concentration,amount and duration of exposure to the chemical .A physician may need to examine the area if irritation or pain persist.
Home irrigation-exposed eyes should be irrigated with copious amounts of water for at least 30 minutes.An examination should always be performed.Ophthalmologic consultation should be obtained.Medical facility:irrigate with sterile 0.9%Saline for at least an hour or until the cul-de-sacs are free of particulate matter and returned to neutrality(confirm with PH paper).
5. FIRE FIGHTING MEASURES
Extinguish fire using agent suitable for type of surrounding fire.(Material itself does not burns with difficulty.)Use water in flooding quantities as fog.Cool all affected containers with flooding quantities of water.Apply water from as far a distance as possible.
6. ACCIDENTAL RELEASE MEASURES/SPILL OR LEAK PROCEDURES
Build dikes to contain flow as necessary.
Neutralize spilled material with crushed limestone,soda ash, or lime.
7. HANDLING AND STORAGE
7.1 Storage Requirement
Store in a cool,dry location in a sealed container.
Containers of this material may be hazardous when emptied.Since emptied containers retain product residues(vapor,liquid,and /or solid),all hazard precautions given in the data sheet must be observed.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
8.1 Personal Protection
Wear appropriate protective gloves,clothing and goggles,and anti-slipping shoes.
Wear positive pressure self-contained breathing apparatus.
