SECTION 3 HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance & Odor: Colorless, mobile liquid. Sharp odor.
Health Hazards: Causes severe eye irritation. Causes skin irritation. May be harmful if swallowed. May cause
CNS depression.
Physical Hazards: FLAMMABLE. Vapors are heavier than air. Vapors may travel across the ground and reach
remote ignition sources causing a flashback fire danger.
Inhalation:
Vapors may be irritating to respiratory system. Breathing of high vapor concentrations may cause central nervous
system (CNS) depression resulting in dizziness, light-headedness, headache, nausea and loss of coordination.
Continued inhalation may result in unconsciousness and death.
Eye Contact:
Severely irritating to the eyes causing pain, redness, swelling and blurred vision.
Skin Contact:
Irritating to the skin causing a burning sensation, redness and/or swelling. Prolonged or repeated skin contact
can cause defatting and drying of the skin which may result in a burning sensation and a dried, cracked
appearance.
Ingestion:
May be harmful if swallowed. Liquid can directly enter the lungs (aspiration) when swallowed or vomited. Serious
lung damage and possibly fatal chemical pneumonia (chemical pneumonitis) can develop if this occurs.
SECTION 4 FIRST AID MEASURES
Inhalation:
Move victim to fresh air. If the victim has difficulty breathing or tightness of the chest, is dizzy, vomiting or
unresponsive, give 100% oxygen with rescue breathing or CPR as required and transport to the nearest medical
facility.
Isobutyl Alcohol MSDS # 5270 Page of
Skin:
Remove contaminated clothing. Flush with large amounts of water for at least 15 minutes, by the clock, and
follow by washing with soap if available. If redness, swelling, pain and/or blisters occur, transport to the nearest
medical facility for additional treatment.
Eye:
Flush eyes with large amounts of water for at least 15 minutes, by the clock, while holding eyelids open.
Transport to nearest medical facility for additional treatment.
Ingestion:
DO NOT induce vomiting. Have victim rinse mouth out with water, then drink sips of water to remove taste from
mouth. DO NOT GIVE LIQUIDS TO A DROWSY, CONVULSING OR UNCONSCIOUS PERSON. If vomiting
occurs spontaneously, keep head below hips to prevent aspiration. Transport to nearest medical facility for
additional treatment.
SECTION 5 FIRE FIGHTING MEASURES
Flash Point [Method]: 86 潞F/30 潞C
Flammability in Air: 1.7 - 10.6 %volume
Extinguishing Media:
Use 'alcohol foam', dry chemical or carbon dioxide (CO2) to extinguish flames.
Fire Fighting Instructions:
FLAMMABLE. Clear fire area of all non-emergency personnel. Do not enter confined fire space without full
bunker gear (helmet with face shield, bunker coats, gloves and rubber boots), including a positive pressure,
NIOSH approved, self-contained breathing apparatus. Containers exposed to intense heat from fires should be
cooled with large quantities of water to prevent weakening of container structure which could result in container
rupture.
Unusual Fire Hazards:
Vapors are flammable and heavier than air. Vapors may travel across the ground and reach remote ignition
sources causing a flashback fire danger.
SECTION 6 ACCIDENTAL RELEASE MEASURES
FLAMMABLE. Vapors are flammable and heavier than air. Vapors may travel across the ground and reach
remote ignition sources causing a flashback fire danger.
Protective Measures:
Evacuate area of unprotected personnel. Eliminate potential sources of ignition (no smoking, flares, sparks or
flames in immediate area). Stay upwind and keep out of low areas. Handling equipment must be bonded and
grounded to prevent sparking.
Wear appropriate personal protective equipment when responding to spills. Refer to Section 8.
Spill Management:
Shut off source of leak if safe to do so. Dike and contain spill. Use water spray (fog) to reduce vapors or divert
vapor cloud drift. If vapor cloud forms, use water fog to suppress or blanket spill area with foam. Remove with
vacuum trucks or pump to storage/salvage vessels. Soak up residue with an absorbent such as clay, sand or
other suitable material and dispose of properly. Flush area with water to remove trace residue. Contain run-off
from residue flush and dispose of properly. Prevent entry into waterways, sewer, basements or confined areas.
For small spills: Soak up residue with an absorbent such as clay, sand or other suitable material. Place in non-
leaking container and seal tightly for proper disposal.
Isobutyl Alcohol MSDS # 5270 Page of
Proper disposal should be evaluated based on regulatory status of this material (see Section 15), potential
contamination from subsequent use and spillage, and regulations governing disposal in the local area.
Reporting:
U.S. regulations require reporting releases of this material to the environment which exceed the reportable
quantity to the National Response Center at (800)424-8802. Notify authorities if any exposures to the general
public or environment occurs or is likely to occur.
SECTION 7 HANDLING AND STORAGE
Avoid prolonged or repeated contact with eyes, skin and clothing. Do not taste or swallow. Avoid contact with
eyes, skin and clothing. Wash thoroughly after handling.
Handling:
Surfaces that are sufficiently hot may ignite liquid material. Vapors are flammable and heavier than air. Vapors
may travel across the ground and reach remote ignition sources causing a flashback fire danger.
Keep away from heat, sparks and flame. Extinguish pilot lights, cigarettes and turn off other sources of ignition
prior to use and until all vapors have dissipated. Use explosion-proof ventilation to prevent vapor accumulation
while in use. Properly dispose of any contaminated rags or cleaning materials in order to prevent fires. Air-dry
contaminated clothing in a well-ventilated area before laundering. Bond and ground handling equipment and
transfer containers to prevent sparking.
Container Warnings:
Containers, even those that have been emptied, can contain explosive vapors. Do not cut, drill, grind, weld or
perform similar operations on or near containers.
SECTION 8 EXPOSURE CONTROLS/PERSONAL PROTECTION
Chemical Limit TWA STEL Ceiling Notation
Isobutyl Alcohol ACGIH - TLV 50 ppm (v)
Isobutyl Alcohol OSHA - PEL 100 ppm (v)
Isobutyl Alcohol OSHA - PEL- 50 ppm (v)
Interim
Standard
Shell has adopted as interim standards (IS), the OSHA PELs that were established in 1989 and later rescinded.
Exposure Controls
The level of protection and types of controls necessary will vary depending upon potential exposure conditions.
Appropriate measures include:
Adequate explosion-proof ventilation to control airborne concentrations.
Personal Protection
Personal protective equipment (PPE) selections vary based on potential exposure conditions such as handling
practices, concentration and ventilation. Information on the selection of eye, skin and respiratory protection for
use with this material is provided below.
Eye Protection:
Chemical Goggles, if liquid contact is likely, or Safety Glasses - If there is potential for eye contact.
Skin Protection:
Use protective clothing which is chemical resistant to this material. Selection of protective clothing depends on
potential exposure conditions and may include gloves, boots, suits and other items. The selection(s) should take
into account such factors as job task, type of exposure and durability requirements.
Isobutyl Alcohol MSDS # 5270 Page of
Published literature, test data and/or glove and clothing manufacturers indicate protection is provided by:
Butyl, or Neoprene, or Nitrile Rubber, or Polyvinyl Chloride (PVC), or Viton鈩?
Respiratory Protection:
If engineering controls do not maintain airborne concentrations to a level which is adequate to protect worker
health, an approved respirator must be worn. Respirator selection, use and maintenance should be in
accordance with the requirements of the OSHA Respiratory Protection Standard, 29 CFR 1910.134.
Types of respirator(s) to be considered in the selection process include:
Air-Purifying Respirator for Organic Vapors, Supplied-Air Respirator, Self-contained breathing apparatus
