| Potential
Hazards |
|
| Health |
|
|
Toxic; inhalation, ingestion, or contact (skin, eyes) with vapors, dusts or substance may cause severe injury,
burns, or death.
Reaction with water or moist air will release toxic, corrosive or flammable gases.
Reaction with water may generate much heat, which increase the concentration of fumes in the air.
Fire will produce irritating, corrosive and/or toxic and cause pollution. |
|
| Fire or
Explosion |
|
|
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Vapors may accumulate in confined areas (basement, tanks, hopper/tanks cars
etc.).
Substance will react with water (some violently), releasing corrosive and/or gases.
Reaction with water may generate much heat, which will increase the concentration of fumes in the air.
Contact with metal may evolve flammable hydrogen gas.
Containers may explode when heated or if contaminated with water.

Note
Most foams will react with the material and release
corrosive/toxic gases.
Small Fires
CO2 (except
for Cyanides), dry chemical, dry sand, alcohol-resistant
foam.
Large Fires |
|
 |
- |
Water spray, fog
or alcohol-resistant foam. |
| - |
Move containers
from fire area if you can do it without risk.
|
| - |
Do not use straight
streams. |
| - |
Dike fire control
water for later disposal; do not scatter the

| Fire involving
Tanks or Car/Trailer Loads |
|
|
- |
Fight fire from
maximum distance or use unmanned hose holders or
monitor nozzles.
|
| - |
Do not get water
inside containers. |
| - |
Cool containers
with flooding quantities of water until well after
fire is out.
|
| - |

immediately in case of rising sound from venting
safety devices or discoloration of tank.
|
| - |
ALWAYS stay away
from the ends of tanks. |

when handling the product must be grounded.
|
| - |
Do not touch
damaged containers or spilled materials unless
wearing appropriate protective clothing.

| - |
A vapor
suppressing foam may be used to reduce vapors.
|
| - |
DO NOT
GET WATER INSIDE CONTAINERS. |
| - |
Use
water spray to reduce vapors or divert vapor cloud
drift.
|
| - |
Prevent
entry into waterways, sewers, basements or
confined areas.
|
| - |
Small
spills cover with dry earth, dry sand, or other
non-combustible material followed with plastic
sheet to minimize spreading or contact with rain.
|

| First Aid |
|
|
- |
Move victim to fresh air - call emergency medical care. |
| - |
Apply artificial respiration if victim is not breathing. |
| - |
Do not use mouth-to-mouth method if victim ingested or inhaled the substance; include artificial respiration with the aid of a pocket musk equipped with a one-way valve or other proper respiratory medical device. |
| - |
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. |
| - |
For minor skin contact, avoid spreading material on unaffected skin. |
| - |
Keep victim warm and quiet. |
| - |
Effects of exposures (inhalation, ingestion or skin contact) to substance may be delayed. |
| - |
Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. |
| - |
Give demulcents as cold milk, egg white by mouth. |
| - |
Give pethidine to relief severe pain. |
| - |
Give dextrose 5% and saline 0.9% 500 ml.I.V. to correct fluid and electrolyte imbalance. |
| - |
Steroids should be started immediately by giving 0.1 mg/kg body weight or give prednisone 1-2 mg/kg body weight. this should be continued for 3 weeks and then diminish the dose gradually. |
| - |
Give antibiotics if there are specific indications for it. |
|
|
| . |
NEVER
give carbonate or bicarbonate. |
| . |
NEVER
induce emesis. |
| . |
NEVER
do gastric lavage. |
| . |
NEVER
give weak alkalis as calcined
magnesia or lime water by mouth because they
produce exothermic reaction heat more
destruction of the tissues. |
|
|
|
|
|
| Disposal
and Waste Treatment |
|
|
Add slowly to a large amount of solution of soda ash and a label lime by stirring.
Discharge the solution with large amount of water into a skin lined with protective matting and filled with shipped marble.
