**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Flammable. Irritating to skin. May cause sensitization by skin
contact. Very toxic to aquatic organisms, may cause long-term adverse
effects in the aquatic environment.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Prolonged and/or repeated contact may cause defatting of the skin and
dermatitis.
Ingestion:
May cause digestive tract disturbances.
Inhalation:
May cause respiratory tract irritation.
Chronic:
In 2-year gavage studies, there was clear evidence of carcinogenic
activity of d-limonene for male rats, as shown by increased
incidences of tubular cell hyperplasia, adenomas, and adenocarcinomas
of the kidney. There was NO evidence of carcinogenic activity of
d-limonene for female rats, for male mice, or for female mice.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with soap and plenty of
water. Remove contaminated clothing and shoes. Get medical aid if
symptoms occur. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Containers may explode in the heat of a fire.
Flammable liquid and vapor. Vapors are heavier than air and may
travel to a source of ignition and flash back. Vapors can spread
along the ground and collect in low or confined areas. This liquid
floats on water and may travel to a source of ignition and spread
fire.
Extinguishing Media:
Use water fog, dry chemical, carbon dioxide or alcohol type foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Forms smooth, slippery surfaces on
floors, posing an accident risk. Remove all sources of ignition.
Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Ground and bond containers when transferring material. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep away from
heat, sparks and flame. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames. Use only with adequate ventilation. Avoid breathing vapor or
mist.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area. Separate from oxidizing
materials. Partially filled containers should be blanketed with
nitrogen.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 5989-27-5:


Personal Protective Equipment

Eyes:
Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use. Wear a NIOSH/MSHA
or European Standard EN 149 approved full-facepiece
airline respirator in the positive pressure mode with
emergency escape provisions.
