hazard. May cause irritation to the respiratory tract. Symptoms may include
coughing, sore throat, labored breathing, and chest pain.
Ingestion:
No information found, but compound should be handled as a potential health
hazard. May cause irritation to the gastrointestinal tract. Symptoms may include
nausea, vomiting and diarrhea.
Skin Contact:
No information found, but compound should be handled as a potential health
hazard. May cause irritation with redness and pain. May be absorbed through the
skin with possible systemic effects.
Eye Contact:
No information found, but compound should be handled as a potential health
hazard. May cause irritation, redness and pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Get medical attention.
Ingestion:
Give large amounts of water to drink. Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean
shoes before reuse. Get medical attention if symptoms occur.
Eye Contact:
Catalog # 10900
Araldite 502 Resin Page 2 of 7
Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper
and lower eyelids occasionally. Get medical attention if irritation persists.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-
contained breathing apparatus with full facepiece operated in the pressure demand
or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as
specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal.
Vacuuming or wet sweeping may be used to avoid dust dispersal.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect
against physical damage. Containers of this material may be hazardous when
empty since they retain product residues (dust, solids); observe all warnings and
precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures as low as possible. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its source, preventing
dispersion of it into the general work area. Please refer to the ACGIH document,
Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for
details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to dust or mist is apparent and engineering
Catalog # 10900
Araldite 502 Resin Page 3 of 7
controls are not feasible, a particulate respirator (NIOSH type N95 or better filters)
may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are
present, use a NIOSH type R or P filter. For emergencies or instances where the
exposure levels are not known, use a full-face positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-
deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities
in work area.
