4.1 FIRST AID PROCEDURES
Page 2 of 8
3M MATERIAL SAFETY DATA SHEET 3M(TM) Scotch-Weld(TM) Threadlocker 3494, Blue 07/05/2005
The following first aid recommendations are based on an assumption that appropriate personal and industrial hygiene practices are
followed.
Eye Contact: Immediately flush eyes with large amounts of water for at least 15 minutes. Get immediate medical attention.
Skin Contact: Remove contaminated clothing and shoes. Immediately flush skin with large amounts of water. Get medical
attention. Wash contaminated clothing and clean shoes before reuse.
Inhalation: Remove person to fresh air. If signs/symptoms develop, get medical attention.
If Swallowed: Do not induce vomiting unless instructed to do so by medical personnel. Give victim two glasses of water. Never
give anything by mouth to an unconscious person. Get medical attention.

5.3 PROTECTION OF FIRE FIGHTERS
Special Fire Fighting Procedures: Water may be used to blanket the fire. Wear full protective equipment (Bunker Gear) and a
self-contained breathing apparatus (SCBA).
Unusual Fire and Explosion Hazards: No unusual fire or explosion hazards are anticipated.
Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition
information.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Accidental Release Measures: Observe precautions from other sections. Call 3M- HELPS line (1-800-364-3577) for more
information on handling and managing the spill. Evacuate unprotected and untrained personnel from hazard area. The spill should be
cleaned up by qualified personnel. Ventilate the area with fresh air. For large spill, or spills in confined spaces, provide mechanical
ventilation to disperse or exhaust vapors, in accordance with good industrial hygiene practice. Warning! A motor could be an ignition
source and could cause flammable gases or vapors in the spill area to burn or explode. Contain spill. For larger spills, cover drains
and build dikes to prevent entry into sewer systems or bodies of water. Working from around the edges of the spill inward, cover with
bentonite, vermiculite, or commercially available inorganic absorbent material. Mix in sufficient absorbent until it appears dry.
Collect as much of the spilled material as possible. Clean up residue with an appropriate solvent selected by a qualified and
authorized person. Ventilate the area with fresh air. Read and follow safety precautions on the solvent label and MSDS. Collect the
resulting residue containing solution. Place in a closed container approved for transportation by appropriate authorities. Dispose of
collected material as soon as possible.
In the event of a release of this material, the user should determine if the release qualifies as reportable according to
local, state, and federal regulations.

NFPA Hazard Classification
Health: 2 Flammability: 1 Reactivity: 1 Special Hazards: None
National Fire Protection Association (NFPA) hazard ratings are designed for use by emergency response personnel to address the hazards that are
presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies. Hazard ratings are primarily based on the
inherent physical and toxic properties of the material but also include the toxic properties of combustion or decomposition products that are known to
be generated in significant quantities.
