SECTION 4: First aid measures
4.1. Description of first aid measures
First-aid measures after inhalation
:
If symptoms of lung irritation occur (coughing, wheezing or breathing difficulty), remove from
exposure area to fresh air immediately. If breathing has stopped, perform emergency
resuscitation. Keep affecte
d person warm and at rest. Get medical attention.
First-aid measures after skin contact
:
In case of contact, wash skin with plenty of soap and water. Remove contaminated clothing and
shoes and launder before reuse. If skin irritation develops and persist
s or recurs, get medical
attention.
First-aid measures after eye contact
:
In case of contact with dust, immediately flush eyes with plenty of water for at least 15 minutes. If
irritation persists, get medical attention.
First-aid measures after ingestion
:
Ingestion of this product is highly unlikely and no first aid should be needed. If product is
ingested and symptoms develop, do not induce vomiting except on advice of competent medical
personnel. Get medical attention immediately if product is ingeste
d and symptoms develop.
4.2. Most important symptoms and effects, both acute and delayed
Symptoms/injuries after inhalation
:
Inhalation of dusts generated from this product is likely to irritate the respiratory tract. Repeated
exposures to dusts generat
ed from this product may cause irritation of the respiratory tract.
Occupational exposure studies with have shown some association with obesity, arterial
hypertension, and liver enlargement at copper duct exposure levels ranging from 111 to 434 mg
Cu/m3. Repeated exposure to dusts may also have effects on the central nervous system (CNS).
Epidemiological data has shown some association of repeated exposure to aluminium dust and
the development of Alzheimer’s disease. Other neurological effects that could de
velop include
impairment of cognitive function and motor dysfunction.
Symptoms/injuries after skin contact
:
May cause mechanical irritation of the skin.
Symptoms/injuries after eye contact
:
May cause mechanical irritaiton of the eye.
Symptoms/injuries after ingestion
:
May be harmful if swallowed.
4.3. Indication of any immediate medical attention and special treatment needed
No additional information available
SECTION 5: Firefighting measures
5.1. Extinguishing media
Suitable extinguishing media
:
Use special powder foam (Extinguisher Class D) for metal fires if substances react to produce
liquid metal. This eliminates the source of oxygen and extinguishes the fire. Class D
extinguishing powder or dry sand will effectively retard the spread of the f
ire.
Unsuitable extinguishing media
:
Water.
5.2. Special hazards arising from the substance or mixture
Fire hazard
:
Copper based welding/joining materials are exothermic mixtures which, when reacted, produce
hot molten materials at temperatures in exc
ess of 2200 °C and a localiz
ed release of smoke. Hot
molten metals are best extinguished with fire extinguisher Class D.
Explosion hazard
:
None
5.3. Advice for firefighters
Protection during firefighting
:
Firefighters should wear full protective gear.
Special firefighting procedures
:
If the packaging materials were to be made combustible before reaching the substances, direct
application of water in a heavy continuous stream is recommended before the fire can spread to
the substances. Water should be
applied from a safe distance with extinguishing hose. If the
packaging materials have been burnt through then the immediate and direct application of large
quantities of extinguishing powder (Class D) or dry sand will effectively retard the spread of the
fire and effectively control it.
SECTION 6: Accidental release measures
6.1. Personal precautions, protective equipment and emergency procedures
6.1.1. For non-emergency personnel
Spilled material may produce a dust hazard if not handled correctly. Wear appropriate protective equipment- coveralls, gloves and eye protection.
Use non-conductive and non-static cleaning gear. Never smoke when handling exothermic materials.
