Inhalation
If inhaled, remove to fresh air. If breathing is difficult, give oxygen. If unconscious, evaluate the need for
artificial respiration. Get immediate medical attention.
Skin contact
Immediately wash skin with soap and plenty of water. Remove contaminated clothing. Obtain medical
attention immediately if symptoms occur. Wash clothing before reuse.
Eye contact
In case of contact, immediately flush eyes with plenty of water. Obtain medical attention if irritation
develops.
Ingestion
If swallowed, do not induce vomiting: seek medical advice immediately and show this container or label.

4.3. Indication of any immediate medical attention and special treatment needed
None known.

5. Fire-fighting measures
5.1. Extinguishing media
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide., Dry
Chemical combined with peroxide may reignite fire., Light water additives may be particularly effective at
extinguishing peroxide fires.
Unsuitable extinguishing media: High volume water jet.
5.2. Special hazards arising from the substance or mixture
The heat of decomposition of the peroxides adds to the heat of the fire. Dry chemical fire extinguishing
agent may catalyze the decomposition.
5.3. Advice for firefighters
If dry chemical is used to extinguish a peroxide fire, the extinguished area must be thoroughly wetted down
with water to prevent reignition.
As in any fire, wear self-contained positive-pressure breathing apparatus and full protective gear.

Containers near the source of fire should be cooled with a water spray to prevent contents from reaching
decomposition temperature.

6. Accidental release measures
6.1. Personal precautions, protective equipment and emergency procedures
Evacuate personnel to safe areas. Wear a self-contained breathing apparatus and appropriate personal
protective equipment. (See Section 8 – Exposure Controls/Personal Protection.) Remove all sources of
ignition. Ventilate the area.
6.2. Environmental precautions
Obey relevant local, state, provincial and federal laws and regulations. Do not contaminate any lakes,
streams, ponds, groundwater or soil.
6.3. Methods and material for containment and cleaning up
Dike spill to prevent runoff from entering drains, sewers, streams, etc. Wet spilled material with water and
absorb with an inert absorbent material such as perlite, vermiculite, or sand. Sweep up using non-sparking
tools and place in a clean polyethylene drum or a polyethylene pail. DO NOT place into a steel container,
lined or unlined, as decomposition may occur. Treat any contaminated cardboard packaging as hazardous
waste. Wet container with additional water prior to sealing. Use absorbent/absorbent material to solidify
liquids. Clean up promptly by sweeping or vacuum. Wear protective equipment, including eye protection,
to avoid exposure (see Section 8 for specific handling precautions).

7. Handling and storage
7.1. Precautions for safe handling
Rotate stock using the oldest material first. Avoid contact with skin, eyes and clothing. Use PPE as
specified in section 8. Keep containers closed to prevent contamination. Keep away from sources of heat,
sparks, or flame. Do not add to hot solvents or monomers as a violent decomposition and/or reaction may
result. When using spray equipment, never spray raw peroxide onto curing or into raw resin or flues. Keep
peroxide in its original container. DO NOT USE NEAR FOOD OR DRINK. Wash thoroughly after handling.
Protect from contamination. Keep tightly sealed in original packing. Risk of decomposition. Wash
thoroughly after handling.
7.2. Conditions for safe storage, including any incompatibilities

Storage
The stability of peroxide formulations us directly related to the shipping and storage temperature history.
Cool storage at 80 F (27 C) or below is recommended for longer shelf life and stability. Prolonged storage
at elevated temperatures of 100 F (38 C) and higher will cause product degradation, gassing and
potential container rupture which can result in a fire and/or explosion. Store out of direct sunlight in a well
ventilated area away from combustible and incompatible material. DO NOT STORE WITH FOOD OR
DRINK.
Refer to NFPA 400 Hazardous Materials Code from the National Fire Protection Association for additional
storage information.
Further information
Store apart from other dangerous and incompatible substances.
STORE BELOW 38 C (100 F).
Keep away from direct sunlight.
Keep containers tightly closed in a cool, well-ventilated place.

8. Exposure controls/personal protection
8.1. Control parameters
Other information

8.3.
Personal protective equipment
Respiratory protection
A respiratory protection program that meets OSHA 1910.134 and ANSI Z88.2 or applicable
federal/provincial requirements must be followed whenever workplace conditions warrant respirator use.
NIOSH’s “Respirator Decision Logic” may be useful in determining the suitability of various types of
respirators.
Hand protection
Wear protective gloves made of the following materials:.
Solvent-resistant gloves (butyl-rubber)
Nitrile rubber
Neoprene gloves
Skin should be washed after contact.
Eye protection
Use chemical splash goggles or face shield.
Skin and body protection
A safety shower and eye wash fountain should be readily available.
To identify additional Personal Protective Equipment (PPE) requirements, it is recommended that a
hazard assessment in accordance with the OSHA PPE Standard (29CFR1910.132) be conducted before
using this product.
Hygiene measures
Do not eat, drink or smoke during use.
Wash hands before breaks and immediately after handling the product.
Protective measures
Personal protective equipment comprising: suitable protective gloves, safety goggles and protective
clothing
