HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance & Odor: Colorless liquid. Fruity odor.
Health Hazards: Toxic and harmful if inhaled. May be harmful if absorbed through the skin. Can cause severe lung damage and may be fatal if swallowed. Causes severe eye irritation. May be harmful if swallowed. May cause CNS depression. May cause cancer. May cause allergic skin reaction.
Health Effects
Inhalation:
Toxic and harmful if inhaled. 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:
May be slightly irritating to the skin. Slightly toxic and may be harmful if absorbed through the skin. Repeated skin contact may result in an allergic skin reaction causing itching, burning, redness and swelling.
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.
Other Health Effects:
May cause cancer. Can result in central nervous system (CNS) depression and peripheral nerve damage.
Primary Target Organs:
Central Nervous System, Peripheral Nervous System
Signs and Symptoms:
Peripheral nerve damage may be evidenced by loss or impairment of motor function (incoordination, unsteady walk or muscle weakness in the extremities) and/or loss of sensation in the arms and legs.
SECTION 4
FIRST AID MEASURES
Inhalation:
DO NOT attempt to rescue the victim unless proper respiratory protection is worn. 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.
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.
Skin:
Remove contaminated clothing. Flush exposed area with water and follow by washing with soap if available. 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.
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: -35°F / -37.22°C
Autoignition Temperature: 840°F / 448.89°C
Flammability in Air: 2.3 - 37 %volume
Extinguishing Media:
Use water fog, 'alcohol foam', dry chemical or carbon dioxide (CO2) to extinguish flames.
Fire Fighting Instructions:
EXTREMELY 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.
SECTION 6
ACCIDENTAL RELEASE MEASURES
EXTREMELY FLAMMABLE. Vapors are flammable and heavier than air. Vapors may travel across the ground and reach remote ignition sources causing a flashback fire danger.
Spill Management:
Shut off source of leak if safe to do so. Dike and contain spill. Use foam to reduce vapors or divert vapor cloud drift. If vapor cloud forms, blanket spill area with foam. If vapor cloud forms, use water fog to suppress or blanket spill area with foam. Remove with explosion-proof vacuum trucks or pump to storage/salvage vessels. Remove with vacuum trucks or pump to storage/salvage vessels. Soak up residue with sand or other suitable material (DO NOT use clay or materials such as millisorb) 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 sand or other suitable material. Place in non-leaking container and seal tightly for proper disposal.
Disposal:
This product is reactive. DO NOT dispose of unreacted product. Proper disposal should be evaluated based on regulatory status of this material (refer to Section 13), potential contamination from subsequent use and spillage, and regulations governing disposal in the local area.
SECTION 7
HANDLING AND STORAGE
Do not taste or swallow. Do not breathe material. Keep container closed. Use only with adequate ventilation. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling. Odor threshold range is 10-199 ppm, with 45 ppm being the average for most people. Odor is inadequate warning of concentrations exceeding exposure limits.
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. Polymerization may cause violent rupture of cargo tanks or piping.
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. Contaminated leather articles including shoes cannot be decontaminated and should be destroyed to prevent reuse. Air-dry contaminated clothing in a well-ventilated area before laundering. Static electricity may accumulate and create a fire hazard. Bond and ground handling equipment and transfer containers to prevent sparking.
Storage:
Keep containers closed when not in use. Protect from atmosphere and water. Do not store at temperatures above 122°F (50°C).
Ground fixed equipment.
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
Shell has adopted as Interim Standards, 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 below the exposure guidelines/limits.
Personal Protective Equipment
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
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.
Published literature, test data and/or glove and clothing manufacturers indicate protection is provided by:
Silver Shield
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 (SCBA) - for use in environments with unknown concentrations or emergency situations.
