Exposure Limits

Duster

Eye: Flush eyes with water. Get medical attention if irritation develops and persists. For direct contact
with spray, flush immediately and get medical attention.

Skin: Wash area with soap and water. Get medical attention if irritation develops and persists. Treat
frostbitten or frozen skin by immersing affected area in lukewarm water. Get medical attention.

Inhalation: None needed under normal use conditions. If irritation develops, move to fresh air. Get
medical attention for serious overexposure of if symptoms persist.

Ingestion: Ingestion is an unlikely route of exposure for aerosol products. If ingestion occurs rinse mouth
with a small amount of water. Get medical attention. Never give anything by mouth to an unconscious or
drowsy person.

Most Important symptoms and effects, both acute and delayed: May cause mild eye irritation.
Spraying product directly on skin or in eyes may cause freezing of tissues. Inhalation may cause upper
respiratory tract irritation.

Indication of any immediate medical attention and special treatment needed: Immediate medical
attention is required if frostbite occurs from spraying directly in eyes or on skin.

SECTION 5: FIRE-FIGHTING MEASURES

Suitable and Unsuitable Extinguishing Media: Use any media that is appropriate for the surrounding

fire.
Special Hazards Arising from the Chemical: Contents under pressure. Container may rupture or

explode in the heat of a fire. Prolonged exposure to temperatures above 120F may cause cans to burst.
Combustion may produce carbon oxides, hydrogen fluoride, hydrofluoric acid, carbonyl fluoride and
fluorocarbons.

Special Protective Equipment and Precautions for Fire-Fighters: Wear NIOSH approved, positive
pressure, self-contained breathing apparatus and full protective clothing. Cool fire exposed containers with
water. Protect against bursting cans.

SECTION 6: ACCIDENTAL RELEASE MEASURES

Personal Precautions, Protective Equipment and Emergency Procedures: Wear appropriate

personal protective equipment. Ventilate area.

Environmental Hazards: Report spills and releases as required to appropriate authorities.
Methods and Material for Containment and Cleaning Up: Remove leaking containers to a well

ventilated area and allow gas to dissipate.

SECTION 7: HANDLING AND STORAGE

Precautions for Safe Handling: Avoid contact with eyes. Avoid breathing vapors and mists. Use with

adequate ventilation. Contents under pressure. Do not puncture or incinerate container.
Conditions for Safe Storage, Including any Incompatibilities: Store in a cool, well-ventilated area at

temperatures below 120F. Do not store in direct sunlight.

Appropriate Engineering Controls: General ventilation should be adequate for normal use. For
operations where the occupational exposure limit may be exceeded, mechanical ventilation such as local
exhaust may be needed to maintain exposure levels below applicable limits.

Individual Protection Measures:
Respiratory Protection: None normally required. For operations where the occupational exposure limit

may be exceeded, a NIOSH approved supplied air respirator is recommended. Selection of respiratory
protection depends on the contaminant type, form and concentration. Select in accordance with OSHA

1910.134 and good Industrial Hygiene practice.
Skin Protection: None required for normal use. For bulk handling and packaging operations, impervious

gloves are recommended.
Eye Protection: None required for normal use. For bulk handling and packaging operations, safety

glasses with side shields are recommended.

Possibility of Hazardous Reactions: None known.
Conditions to Avoid: Dropping containers may cause bursting.
Incompatible Materials: Avoid alkali or alkaline earth metals, powdered metals and powdered metal

salts.
Hazardous Decomposition Products: Decomposition may produce carbon oxides, hydrogen fluoride,

hydrofluoric acid, carbonyl fluoride and fluorocarbons.

SECTION 11: TOXICOLOGICAL INFORMATION

Potential Health Effects:
Eye: May causes mild irritation. Spraying product directly in eyes may cause freezing of tissue.
Skin: Spraying product directly on skin may cause freezing of tissue.
Inhalation: Breathing vapors may cause mild irritation of the mucous membranes and upper respiratory

tract. Excessive overexposure may cause headache, dizziness, drowsiness, irregular heartbeat,
unconsciousness or death from asphyxiation. Presence of bitterant makes inhalation overexposure
unlikely.

Ingestion: Ingestion is unlikely with this product. If liquid is swallowed, freeze injury would be expected.
Presence of bitterant makes ingestion unlikely.

Chronic Hazards: None known.
Carcinogen Status: None of the components of this product are listed as carcinogens by IARC, NTP or

OSHA.
Acute Toxicity Values:

Acute Toxicity Estimate: Inhalation >27,500 ppm/4 hr
1,1,1,2-Tetrafluoroethane: Inhalation rat LC50 567,000 ppm/4 hr

1,1-Difluoroethane: Inhalation rat LC50 >437,500 ppm/4 hr
