2 � Hazards Identification

Emergency Overview:

CAUTION! Contents under pressure. May be irritating to eyes, respiratory tract and skin.

Repeated skin contact may cause allergic skin reaction. Prolonged overexposure may cause

liver, blood, lymphatic system or central nervous system effects. Prolonged or repeated skin

exposure may cause drying, defatting and dermatitis. Use with adequate ventilation. Keep away

from heat, sparks and all other sources of ignition. Avoid eye contact and inhalation.



Symptoms of Overexposure:

Inhalation: Inhalation may cause nose, throat, and respiratory tract irritation, coughing,

headache, and anesthesia. Prolonged exposure to the propellant may cause rapid breathing,

headache and dizziness.

Skin Contact: May cause skin irritation. Prolonged contact may cause defatting, dermatitis, and

drying of the skin. May cause sensitization by skin contact.

Eye Contact: May cause eye irritation with redness, tearing and blurred vision.

Ingestion: May be harmful if swallowed. Ingestion may cause vomiting and headache. May

cause damage to liver and kidneys.

Chronic Effects: May cause blood disorders, liver, lymphatic system and ventral nervous system

effects based on animal data.

Medical Conditions Aggravated by Exposure: Preexisting skin conditions or allergies may be

aggravated by exposure.

4 � First Aid Measures

Ingestion (Swallowed): Do not induce vomiting. Call physician, poison control center or the

WD-40 Safety Hotline at 1-888-324-7596 immediately.

Eye Contact: Flush thoroughly with water for 15 minutes. Get immediate medical attention.

Skin Contact: Wash thoroughly with soap and water. If irritation develops and persists, get

medical attention.







                                          Page 1 of 4

Inhalation (Breathing): If irritation is experienced, move to fresh air. Get medical attention if

irritation or other symptoms develop and persist.



5 � Fire Fighting Measures

Extinguishing Media: Use water fog, dry chemical, carbon dioxide or foam.

Special Fire Fighting Procedures: Firefighters should always wear positive pressure self-

contained breathing apparatus and full protective clothing. Cool fire-exposed containers with

water. Use shielding to protect from bursting cans.

Unusual Fire and Explosion Hazards: Contents under pressure. Keep away from ignition

source and open fire. Exposure of containers to extreme heat and flames can cause them to

rupture often with violent force. Vapors are heavier than air and may travel along the ground to

remote sources and flash back.



6 � Accidental Release Measures

Immediately remove all sources of ignition. Remove personnel from general area. Wear

appropriate protective clothing (see Section 8). Contain and collect liquid with an inert absorbent

and place in a container for disposal. Clean spill area thoroughly. Report spills to authorities as

required.



7 � Handling and Storage

Handling: Avoid contact with eyes. Avoid prolonged contact with skin. Avoid breathing vapors or

aerosols. Use with adequate ventilation. Wash thoroughly with soap and water after handling.

Keep containers closed when not in use. Keep out of the reach of children.

Storage: Store in a cool, well-ventilated area, away from incompatible materials and heat, sparks

or open flame. Do not store in direct sunlight or above 120°F. U.F.C (NFPA 30B) Level 2

Aerosol.
