3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This substance consists of an off-white, odorless powder. The primary health hazard
associated with emergency response to this material is the potential for mild irritation of skin, eyes, and other contaminated
tissue. 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole requires substantial pre-heating before ignition occurs.
When involved in a fire, this material may decompose and produce irritating vapors and toxic compounds (including carbon
monoxide, carbon dioxide, nitrogen oxides, and benzene). This substance is not reactive. Emergency responders must
wear adequate personal protective equipment for the situations to which they are responding.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The HAZARDOUS MATERIAL INFORMATION SYSTEM
main routes of occupational over-exposure to 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-
methylphenyl)-2H-benzotriazole are via inhalation of dusts, as well as
contact with skin or eyes. Currently, the anticipated symptoms of over-

exposure are as follows:
INHALATION: Inhalation is not anticipated to be a significant route of over-
exposure for 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole. If
dusts of this substance are inhaled, mild irritation of the nose and upper

contaminated object may cause intense pain, irritation, and local swelling (in addition to the wound).
HEALTH EFFECTS OR RISKS FROM EXPOSURE (An explanation in lay terms).
ACUTE: 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole may be mildly irritating to contaminated skin, eyes, mucous
membranes, and other contaminated tissue.
CHRONIC: Persistent skin irritation may result from prolonged or repeated skin contact with this substance. Refer to Section
11 (Toxicological Information) for additional data.
TARGET ORGANS: Skin, eyes.
PART II What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
SKIN EXPOSURE: If 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole contaminates the skin, immediately begin
decontamination with warm, running water. Minimum flushing is for 15 minutes. Remove exposed or contaminated clothing,
taking care not to contaminate eyes. Victim must seek medical attention if any adverse effect occurs.
EYE EXPOSURE: If dusts or powders of 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole enter the eyes, open
victim's eyes while under gently running water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum
flushing is for 15 minutes. Victim must seek immediate medical attention.
INHALATION: If dusts of 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole are inhaled, remove victim to fresh air. If
necessary, use artificial respiration to support vital functions. Remove or cover gross contamination to avoid exposure to
rescuers.

4. FIRST-AID MEASURES (Continued)
INGESTION: If 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole is swallowed, CALL PHYSICIAN OR POISON
CONTROL CENTER FOR MOST CURRENT INFORMATION. If professional advice is not available, do not induce vomiting.
Victim should drink milk, egg whites, or large quantities of water. Never induce vomiting or give diluents (milk or water) to
someone who is unconscious, having convulsions, or unable to swallow.
Victims of chemical exposure must be taken for medical attention. Rescuers should be taken for medical attention, if
necessary. Take a copy of the label and the MSDS to health professional with victim.

substantially pre-heated before ignition can occur. When involved in a fire,
this material may decompose and produce irritating vapors and toxic
compounds (including carbon monoxide, carbon dioxide, and benzene). It is
important to note that as with all organic solids, large dusts clouds of this
product have the potential to ignite explosively.
OTHER
Explosion Sensitivity to Mechanical Impact: Not applicable. See Section 16 for
Explosion Sensitivity to Static Discharge: Not applicable. Definition of Ratings
SPECIAL FIRE-FIGHTING PROCEDURES: Structural fire fighters must wear Self-Contained Breathing Apparatus and full
protective equipment. All personal protective gear and contaminated fire-response equipment should be decontaminated with
soapy water before being returned to service. Move fire-exposed containers, if it can be done without risk to firefighters. If
possible, prevent run-off water from entering storm drains, bodies of water, or other environmentally sensitive areas.
6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: In case of a spill, clear the affected area and protect people. Uncontrolled releases should
be responded to by trained personnel using pre-planned procedures. Proper protective equipment should be used.
The minimum personal protective equipment for incidental releases includes gloves, goggles, dust mask, and appropriate
body protection. In the event of a release of 4.5 kg or more of 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole,
minimum Personal Protective Equipment should be Level C: triple-gloves (rubber gloves and nitrile gloves, over latex gloves),
chemically resistant suit and boots, hard-hat, and a high-efficiency particulate filter. Level B, which includes a Self-Contained
Breathing Apparatus, must be worn in situations where the oxygen level is below 19.5% or is unknown. Wet spilled solid with
water before clean-up, to minimize the generation of dusts. Sweep-up or vacuum spilled material carefully, avoiding the
generation of dusts. Rinse the contaminated area with soapy water. Decontaminate the area thoroughly. Place all spill
residue in an appropriate, labeled container and seal immediately. Dispose of in accordance with U.S. Federal, State, and
local hazardous waste disposal regulations, or those of Canada and its Provinces (see Section 13, Disposal Considerations).
PART III How can I prevent hazardous situations from occurring?
7. HANDLING and STORAGE
WORK AND HYGIENE PRACTICES: As with all chemicals, avoid getting 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-
benzotriazole ON YOU or IN YOU. Do not eat, drink, smoke or apply cosmetics while using this material. Ensure this
substance is used with adequate ventilation and personal protective equipment (see Section 8, Engineering Controls and
Personal Protection). Areas in which 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole is used should be wiped-down,
so that this substance is not allowed to accumulate.
STORAGE AND HANDLING PRACTICES: All employees who handle this material should be trained to handle it safely.
Minimize all exposures to this substance.
UV ABSORBER MSDS

7. HANDLING and STORAGE (Continued)
STORAGE AND HANDLING PRACTICES (Continued): Open containers slowly, on a stable surface, in areas which have
been designated for use of 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole. Containers of 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-
methylphenyl)-2H-benzotriazole must be properly labeled.
Store containers in a cool, dry location, away from direct sunlight and sources of intense heat. Store away from incompatible
materials (see Section 10, Stability and Reactivity). Keep containers tightly closed when not in use. Empty containers contain
residual material; therefore, empty containers should be handled with care.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Ensure eyewash/safety shower stations are in areas where 2-(2鈥?-Hydroxy-
3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole is used. Ventilation must be adequate to ensure that exposures to this substance
are kept below the limits recommended in Section 2 (Composition and Information on Ingredients).
3
RESPIRATORY PROTECTION: Respiratory protection is generally not needed under normal circumstances of use or
handling. A full-face Air-Purifying Respirator with high-efficiency particulate filter or a Supplied-Air Respirator should be worn
during operations in which excessive amounts of 2-(2鈥?-Hydroxy-3鈥?-allyl-5鈥?-methylphenyl)-2H-benzotriazole dusts are
generated. When respiratory protection is needed, use only protection authorized in U.S. Federal OSHA Standard (29 CFR
1910.134), applicable U.S. State regulations, or the appropriate standards of Canada and its Provinces. Always use supplied
air respiration protection during emergency response situations in which oxygen levels are below 19.5% or are unknown.
EYE PROTECTION: Splash goggles or safety glasses.
HAND PROTECTION: Wear appropriate, chemically-resistant gloves (i.e. N-Dex; Solvex) for routine use. Use triple gloves
for spill response, as stated in Section 6 (Accidental Release Measures) of this MSDS.
BODY PROTECTION: Use body protection appropriate for task (i.e. lab coat, Tyvek Suit).
