2 � Hazards Identification

Emergency Overview:

CAUTION! Harmful of fatal is swallowed. Combustible Liquid and Vapor. If swallowed, may be

aspirated and cause lung damage. May cause eye, skin and respiratory tract irritation. Avoid eye

contact. Use with adequate ventilation. Keep away from heat, sparks and all other sources of

ignition.



Symptoms of Overexposure:

Inhalation: Mist or vapor can irritate the throat and lungs. High concentrations may cause nasal

and respiratory irritation and central nervous system effects such as headache, dizziness and

nausea. Intentional abuse may be harmful or fatal.

Skin Contact: May cause mild skin irritation with short-term exposure with redness, itching and

burning of the skin. Prolonged and/or repeated contact may produce mild irritation and defatting

with possible dermatitis.

Eye Contact: Contact may be mildly irritating to eyes. May cause redness, stinging, swelling and

tearing.

Ingestion: This product has low oral toxicity. If swallowed, this material may cause irritation of the

mouth, throat and esophagus. Swallowing may cause gastrointestinal irritation, nausea, vomiting,

diarrhea, dizziness, drowsiness, loss of consciousness, delirium and other central nervous

system effects. This product is an aspiration hazard. If swallowed, can enter the lungs and may

cause chemical pneumonitis, severe lung damage and death.

Chronic Effects: Prolonged or repeated skin contact may defeat the skin resulting in irritation

and dermatitis.

Medical Conditions Aggravated by Exposure: Preexisting eye, skin and respiratory conditions

may be aggravated by exposure.



Suspected Cancer Agent:

4 � First Aid Measures

Ingestion (Swallowed): Aspiration Hazard. DO NOT induce vomiting. Call physician, poison

control center or the WD-40 Safety Hotline at 1-888-324-7596 immediately.







                                             Page 1 of 4

Eye Contact: Flush thoroughly with water. Get medical attention if irritation persists.

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

attention.

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. Do not use water jet

or flooding amounts of water. Burning product will float on the surface and spread fire.

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

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

water.

Unusual Fire and Explosion Hazards: Combustible liquid and vapor. This material can release

vapors when heated above ambient temperatures. Vapors can cause a flash fire. Vapors are

heavier than air and may travel along surfaces to remote ignition sources and flash back. A

vapor and air mixture can create an explosion hazard in confined spaces. If container is not

properly cooled, it can rupture in the heat of a fire.



6 � Accidental Release Measures

Wear appropriate protective clothing (see Section 8). Eliminate all sources of ignition and

ventilate area. 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. Keep away from heat, sparks, hot surfaces and open

flames. 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. NFPA 30 Class

II Liquid.
