4. FIRST AID MEASURES-----------Up to Table of Contents
INHALATION:
When safe to enter area, remove from exposure. Use a bag valve mask or similar device to
perform artificial respiration (rescue breathing) if needed. Get medical attention immediately.
SKIN CONTACT:
Remove contaminated clothing, jewelry, and shoes immediately. Wash with soap or mild
detergent and large amounts of water until no evidence of chemical remains (at least 15-20
minutes). Get medical attention, if needed.
EYE CONTACT:
Wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids,
until no evidence of chemical remains. Continue irrigating with normal saline until ready to
transport to hospital. Cover with sterile bandages. Get medical attention immediately.
INGESTION:
Contact local poison control center or physician immediately. Never make an unconscious person
vomit or drink fluids. When vomiting occurs, keep head lower than hips to help prevent aspiration.
If person is unconscious, turn head to side. Get medical attention immediately.
ANTIDOTE:
amyl nitrite, inhalation; sodium nitrite, intravenous; sodium thiosulfate, infusion; oxygen.
NOTE TO PHYSICIAN:
Consider amyl nitrite inhalation, 1 ampoule (0.2 mL) every 5 minutes, and oxygen. For ingestion,
consider gastric lavage. Consider oxygen.
5. FIRE FIGHTING MEASURES-----------Up to Table of Contents
FIRE AND EXPLOSION HAZARDS:
Severe fire hazard. Moderate explosion hazard. Vapor/air mixtures are explosive. May explode
when heated. The vapor is heavier than air. Vapors or gases may ignite at distant ignition sources
and flash back.
EXTINGUISHING MEDIA:
regular dry chemical, carbon dioxide, water, regular foam, alcohol resistant foam
Large fires: Use regular foam or flood with fine water spray.
FIRE FIGHTING:
Do not get water inside container. Cool containers with water spray until well after the fire is out.
Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water
from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then
take the following precautions: Keep unnecessary people away, isolate hazard area and deny
entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device
or any discoloration of tanks due to fire. For tank, rail car or tank truck, evacuation radius: 800
meters (1/2 mile). Water may be ineffective.
FLASH POINT:
30.0 F (-1.1 C) (CC)
LOWER FLAMMABLE LIMIT:
3%
UPPER FLAMMABLE LIMIT:
17%
AUTOIGNITION:
898 F (481 C)
FLAMMABILITY CLASS (OSHA):
IA
6. ACCIDENTAL RELEASE MEASURES-----------Up to Table of Contents
WATER RELEASE:
Subject to California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).
Keep out of water supplies and sewers.
OCCUPATIONAL RELEASE:
Avoid heat, flames, sparks and other sources of ignition. Do not touch spilled material. Stop leak
if possible without personal risk. Reduce vapors with water spray. Small spills: Flood with water.
Large spills: Dike for later disposal. Remove sources of ignition. Keep unnecessary people away,
isolate hazard area and deny entry. Reportable Quantity (RQ): Notify Local Emergency Planning
Committee and State Emergency Response Commission for release greater than or equal to RQ
(U.S. SARA Section 304). If release occurs in the U.S. and is reportable under CERCLA Section
103, notify the National Response Center at (800)424-8802 (USA) or (202)426-2675 (USA).
7. HANDLING AND STORAGE-----------Up to Table of Contents
Store and handle in accordance with all current regulations and standards. Notify State

TPQ (U.S. EPA SARA Section 302). SARA Section 303 requires facilities storing a material with a
TPQ to participate in local emergency response planning (U.S. EPA 40 CFR 355.30). Protect
from physical damage. Store outside or in a detached building. Store with flammable liquids.
Keep separated from incompatible substances. Monitor inhibitor content. Secure to prevent
tipping. Use diking sufficient to contain total contents plus 10%. Keep separated from
incompatible substances.
