3. Hazards Identification
Emergency Overview
Symptoms of acute overexposure:
Skin: Moderate irritant. Contact at elevated temperatures can cause thermal burns. May cause skin
sensitization (rashes, hives.)
Eyes: Eye irritant (tearing, redness, discomfort).
Inhalation: May irritate nose and throat.
Ingestion: May cause gastric distress (nausea). May cause central nervous system depression.
Effects of chronic overexposure: Prolonged or repeated skin contact may cause sensitization, with itching,
swelling, or rashes on later exposure. Pure benzoyl peroxide is reported to be an allergen.
Carcinogenicity: OSHA regulated: No
ACGIH: No National Toxicology Program: No
International Agency for Research on Cancer: No Cancer suspected constituents: None
Medical conditions which may be aggravated by exposure: Skin and eye disorders.

4. First Aid Measures
First aid for eyes: Make sure to remove any contact lenses from the eyes before rinsing. Flush eye with
clean water for at least 15 minutes while gently holding eyelids open. Get immediate medical attention if
symptoms occur after washing.
First aid for skin: Immediately remove contaminated clothing or excess containment. Flush skin with water.
Wash thoroughly with soap and warm water. Consult a physician if irritation develops.
First aid for inhalation: Remove individual to fresh air. Administer oxygen if breathing is difficult. Place
unconscious person on the side in the recovery position to ensure breathing. Get medical attention if
symptoms persist.
First aid for ingestion: Do not induce vomiting. If patient is conscious, immediately rinse mouth and drink
plenty of water or milk. Keep person under observation. If vomiting occurs, keep head low. Transport
immediately to hospital and show attending physician this Material Safety Data Sheet.
5. Fire Fighting Measures
GENERAL FIRE AND EXPLOSION CHARACTERISTICS: Decomposition products can be flammable. Selfaccelerating decomposition temperature is 129°F (estimated).
EXTINGUISHING MEDIA: Foam, carbon dioxide or dry powder. Dry chemicals, sand, dolomite, etc.
Flash Point (°F): NA
Method: (no flashpoint method for peroxides)
Explosive limits in air (percent) – Lower: NA
Upper: NA
SPECIAL FIRE FIGHTING PROCEDURES: If large amounts of material are involved, evacuate the area and
fight fire from safe distance. Cool fire-exposed containers with water.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Benzoyl peroxide can decompose violently if heated
strongly while confined.
HAZARDOUS PRODUCTS OF COMBUSTION: Carbon monoxide and carbon dioxide.
6. Accidental Release Measures
PERSONAL PRECAUTIONS: Avoid personal contact. Eliminate ignition sources. Ventilate area. If contact
cannot be avoided, wear protective clothing as described in Section VIII of this safety data sheet.
ENVIRONMENTAL PRECAUTIONS: Do not let product enter drains. Avoid subsoil penetration. Spillage or
uncontrolled discharges into watercourses must be IMMEDIATELY alerted to the Environmental Agency or
other appropriate regulatory body.
CONTAINMENT AND CLEAN UP: Dike, contain and absorb with clay, sand or other suitable material and
then place into containers. Flush area with water to remove trace residue. Wash thoroughly after dealing
with a spillage.
7. Handling and Storage
HANDLING PRECAUTIONS:
 Use non-sparking equipment
 Do not get in eyes, on skin, or on clothing
2


Avoid breathing vapors
Use only as directed; avoid uncontrolled mixing with other materials, especially polymerizable or
combustible materials.
STORAGE PRECAUTIONS: Store out of direct sunlight in a cool, well-ventilated place. Store below 100°F
to maintain stability and active oxygen content. Keep from heat, sparks, and open flame. Exposure to high
heat can cause a violent reaction. Do not store near combustibles. Refer also to National Fire Protection
Agency (NFPA) Code 432, Code for the Storage of Organic Peroxide Formulations.
STORAGE CLASS: Chemical storage.
8. Exposure Controls, Personal Protection
PROTECTIVE EQUIPMENT:
EYE AND FACE PROTECTION: Safety glasses with side shields.
SKIN PROTECTION: Chemical-resistant gloves and other gear as required to prevent skin contact.
RESPIRATORY PROTECTION: None required at normal handling temperatures and conditions.
OTHER PROTECTION: Chemical resistant apron, protective suit, safety shoes / boots.
PROCESS CONDITIONS: Provide eyewash station.
ENGINEERING MEASURES: Ventilation: Local exhaust is recommended for confined areas. General
mechanical ventilation is adequate for normal use.
HYGIENE MEASURES: DO NOT SMOKE IN WORK AREA! Wash at the end of each work shift and before
eating, smoking and using the toilet. Promptly remove any clothing that becomes contaminated. Use
appropriate skin cream to prevent drying of skin. When using this material, do not eat, drink or smoke.
Handle in accordance with good industrial hygiene and safety practices.

11. Toxicological Information
Acute oral effects: LD50 (rat): No data. BPO: slightly toxic to practically non-toxic to rats.
Acute dermal effects: LD50 (rabbit): No data. BPO: non-irritating to rabbits (4-hr exposure). Repeated
controlled human skin contact studies produced skin allergy.
Acute inhalation effects: LC50 (rat): No data. BPO: practically non-toxic to rats (LC50>22.4mg/L, 4hr).
Pure benzoyl peroxide causes respiratory irritation.
Eye irritation: BPO: Severely irritating to rabbits.
Sub chronic effects: Not available.
Carcinogenicity, teratogenicity and mutagenicity: BPO: both positive and negative (mutagenic and nonmutagenic) responses occurred in tests with animal or bacterial cells. Repeated skin application with a known
carcinogen enhanced skin tumor production in mice by the carcinogen.
Other chronic effects: BPO: Rats fed does of 2800 mg/kg for 2 years showed increased incidence of
testicular atrophy. Pure benzoyl peroxide is reported to be an allergen.
