157 Substances - Toxic and/or Corrosive
 |
(Non-Combustible/Water-Sensitive) |
|
| 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
will increase the concentration of fumes in the air. * Fire will produce irritating,
corrosive and/or toxic gases. * Runoff from fire control or dilution water may be
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/tank cars, etc.). * Substance will react with water (some violently), releasing
corrosive and/or toxic gases. * Reaction with water may generate much heat which will
increase the concentration of fumes in the air. * Contact with metals may evolve flammable
hydrogen gas. * Containers may explode when heated or if
contaminated with water. |
PUBLIC
SAFETY |
*
CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not
available or no answer, refer to appropriate telephone number listed on the inside back
cover. * Isolate spill or leak area immediately for at least 50 to 100 meters (160 to 330
feet) in all directions. * Keep unauthorized personnel away. * Stay upwind. * Keep out of
low areas. * Ventilate enclosed areas. |
PROTECTIVE
CLOTHING |
*
Wear positive pressure self-contained breathing apparatus (SCBA). * Wear chemical
protective clothing which is specifically recommended by the manufacturer. It may provide
little or no thermal protection. * Structural firefighters' protective clothing provides
limited protection in fire situations ONLY; it is not effective in spill situations. |
EVACUATION |
Spill:
See the Table of Initial Isolation and Protective Action Distances for highlighted
substances. For non-highlighted substances, increase, in the downwind direction, as
necessary, the isolation distance shown under "PUBLIC SAFETY". |
Fire:
If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2
mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in
all directions. |
| EMERGENCY RESPONSE |
FIRE |
*
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. * Use water spray or fog; do not use straight
streams. * Dike fire control water for later disposal; do not scatter the material. |
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. * Withdraw
immediately in case of rising sound from venting safety devices or discoloration of tank.
* ALWAYS stay away from tanks engulfed in fire. |
SPILL
OR LEAK |
*
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 damaged
containers or spilled material unless wearing appropriate protective clothing. * Stop leak
if you can do it without risk. * 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. Avoid allowing water runoff to contact spilled material. * 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. * Use clean non-sparking
tools to collect material and place it into loosley covered plastic containers for later
disposal. |
FIRST
AID |
*
Move victim to fresh air. * Call 911 or emergency medical service. * Apply artificial
respiration if victim is not breathing. * Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; induce artificial respiration with the aid of a pocket
mask 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 exposure (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. |
