4 FIRST AID MEASURES
SKIN - Wash copiously with soap and water - remove contaminated clothing, including shoes and launder
before re-use. If skin irritation develops seek immediate medical attention.
EYES - As soon as possible irrigate thoroughly with water for at least 15 minutes, holding the eyelids apart. If
in any doubt, or the irritation persists, obtain medical attention.
INHALATION - Ensure that airways are clear and unobstructed. Keep warm and at rest. If there is any difficulty in
breathing, or vomiting has occurred obtain medical attention urgently. If breathing stops or shows signs
of failing, apply mouth to mouth ventilation.
INGESTION - In the event of deliberate ingestion help must be obtained urgently.
Keep at rest. Do not induce vomiting but seek prompt medical attention. Observe patient in case abdominal pain

5 FIRE-FIGHTING MEASURES
Keep product in storage (and in use) away from sources of ignition. In the event of fire, remove all unaffected product (if
possible) away from the immediate vicinity. If necessary cool stocks with water mists. Extinguish burning material with
foam, dry powder, CO2 or halons. DO NOT USE WATER.
6 ACCIDENTAL RELEASE MEASURES
6.1 Small Scale Spillages In the unlikely event of spillages from aerosol cans, place cans in bags or open pail until
pressure has dissipated. Aerosol cans must not be punctured or incinerated but disposed
of in land fill or in accordance with local regulations. Do not wash WD-40 contamination
into drains and waterways. Instead wipe affected areas with white spirit or turpentine
substitute and allow to dry When dry wash affected areas with soapy water to remove
any remnants of WD-40. If white spirit cannot be applied, layer with sawdust or
absorbent material. Allow to dry and then sweep/shovel into refuse bins and dispose of
via public or private waste disposal.
6.2 Large Scale Spillages In the event of large roadside transport spillages resulting from collision or overturned
vehicles, vehicles must be kept away from contaminated roads or other surfaces.
Affected areas should be covered in layers of sawdust or similarly absorbent material. Do
not wash into drains, waterways or soil courses. Later remove absorbent material to waste
disposal site. Marine spillages should be dealt with in accordance with pollutant
procedures which are relevant to the product classification and IMDG codes.
7 HANDLING AND STORAGE
7.1 Special Handling Information
Ventilation: Must be sufficient to keep solvent vapour less than TLV
Respiratory protection: Advised when concentration of solvent vapour exceeds TLV.
Protective gloves: Advised when skin comes into contact with WD-40 regularly or to prevent possible
skin irritation.
Eye protection: Factory or industrial users are advised to wear protection to guard against potential
eye contact.
Other protection equipment: None required.
7.2 Special Storage Information
There is no special storage information relevant to the keeping of WD-40. It is obvious that aerosols should be
kept away from sources of ignition or ambient temperatures above 50°Celsius. Local laws and fire inspectorates
may also influence storage policies of commercial organisations. Do not store large quantities of WD-40 aerosols
in unventilated bunkers or enclosures.
Keep out of reach of children. Do not spray on naked flame or any incandescent material. No Smoking near
expelled product.
