SECTION 4 - FIRE AND EXPLOSION DATA |
|
|
Non-Flammable;
Flashpoint - None. |
| HAZARDOUS COMBUSTION PRODUCTS: |
Various elemental metals and metal oxides may
be generated during welding or other melting operations. Refer to Section 6 for
permissible exposure limits. |
|
| |
SECTION
5 - REACTIVITY DATA |
| These alloys are stable materials. However, contact with mineral acids
and oxidizing agents should be avoided, as this may cause hydrogen gas to be generated,
and hydrogen may be an explosion hazard. |
|
| |
SECTION 6 - TOXICOLOGICAL PROPERTIES |
| GENERAL HEALTH HAZARDS: |
Under normal handling and use of this
material, there are few health hazards. However, machining, welding, etc., of this
material can produce dust, fume, or particulate containing the component alloy elements.
Particulates may present health hazards if they enter the body by one of the listed routes
in amounts exceeding the exposure limits. |
| PRIMARY ROUTE(S)
OF EXPOSURE: |
| INHALATION: |
Inhalation of metal particulates may result
from welding, grinding or similar operations which generate airborne material. |
| INGESTION: |
This is not a normal route of entry. Hand,
clothing and food or drink contaminated with metal dust or particulate can cause metal
ingestion during hand-to-mouth activities such as eating, drinking smoking and nail
biting. |
| SKIN: |
Irritation, allergic dermatitis or
sensitization may occur from some components. |
| EYE: |
Contamination by airborne particulates or
soiled fingers may result in abrasion or irritation. |
|
|
EFFECTS OF
OVER- EXPOSURE: |
ACUTE:
Inhalation: Short, intensive exposure to copper, chromium and manganese
may cause metal fume fever – a flu-like illness. Some forms of chromium, nickel,
cobalt and tungsten carbides may cause asthma. Cobalt, chromium, boron, copper,
vanadium, molybdenum, nickel and manganese are respiratory irritants. |
|
Skin: Contact with
copper, vanadium and nickel may cause dermatitis. Exposure to cobalt may cause dermatitis
and other allergic skin reactions. Dermal exposure to manganese may result in increased
sweating. Boron and vanadium exposure may cause irritation. |
|
Ingestion: Although an
unlikely route of over-exposure, ingestion of cobalt, copper and vanadium may cause
nausea, vomiting, diarrhea and abdominal pain. |
|
Eye: Particulates may
cause irritation due to mechanical abrasion. Severe irritation or allergic conjunctivitis
may result from contact with cobalt. Exposure to copper may irritate the eyes. |
|
CHRONIC: Chronic health effects specific to an element may be difficult to
detect due to the numerous elements in this alloy. Chronic inhalation effects may include
chronic obstructive lung disease, pulmonary fibrosis, rhinitis and/or bronchitis. Chronic
occupational exposure to cobalt has been associated with polycythemia (an increase in the
total cell mass of the blood), bloody urine, and goitre (enlargement of the thyroid
gland). |

*** IARC Classification:
Group 1 .............................. Sufficient evidence of carcinogenicity in humans.
Group 2A ........................... Probably carcinogenic to humans.
Group 2B ........................... Possibly carcinogenic to humans.
Group 3 .............................. Not classified as to human carcinogenicity.
Group 4 .............................. Probably not carcinogenic to humans. |
| CARCINOGENICITY: Some of the elements
in this alloy have been identified as a cancer risk by The International Agency for
Research on Cancer (IARC). Exposure to cobalt, cobalt compounds, nickel, nickel compounds,
and hexavalent chromium may cause or contribute to an increased risk in cancer among
workers. |
|
| MEDICAL CONDITIONS AGGRAVATED
BY EXPOSURE: |
Individuals who may have had allergic reaction or
sensitivity to metals such as chrome, copper, cobalt and nickel may encounter skin rash or
dermatitis if skin contact with this product occurs. Persons with impaired pulmonary
function, airway diseases and conditions such as asthma, emphysema, chronic bronchitis,
etc., may incur further disability if excessive concentrations of dust or fumes are
inhaled. If prior damage or disease to the Neurologic (nervous), Circulatory, Hematogic
(blood) or Renal (kidney) systems has occurred, proper screening or examinations should be
conducted on individuals who may be exposed to further risk if handling and use of this
material causes excessive exposure. |
|
| |
SECTION
7 - PREVENTATIVE MEASURES |
| VENTILATION: |
To control exposure to airborne dust, fume and
particulate, maintain the working environment below the recommended exposure limits by use
of adequate ventilation. |
| RESPIRATORY: |
If ventilation is not adequate to maintain
levels below the exposure limits, respiratory protection should be used. NIOSH-approved
respirators with a high efficiency particulate air purifying filter are recommended. |
| SKIN: |
Leather or rubber gloves are recommended to
avoid prolonged contact with the skin, and to prevent metal cuts and abrasions. Skin
contact can be minimized by the use of clean, protective coveralls. |
| EYE: |
Wear safety glasses or goggles when
particulates are generated. |
| RECOMMENDED MONITORING PROCEDURES: |
ENVIRONMENTAL SURVEILLANCE:
Exposure to the elements identified in Section 2 can be best determined by having air
samples taken in the employee breathing zone, work area or department. |
|
MEDICAL SURVEILLANCE:Lung
function tests, chest x-rays, and routine physical examinations may be useful to determine
effects of dust or fume exposure. |
| WASTE DISPOSAL: |
It is the ultimate responsibility of the waste
generator to determine at the time of disposal whether the product meets any hazardous
waste criteria. Follow all applicable Federal, Provincial and Local regulations regarding
waste management methods. |
| |
|
SECTION 8 - FIRST AID MEASURES |
| INHALATION: |
Breathing difficulty caused by
inhalation of dust, fumes or particulate requires removal to fresh air. If breathing does
not improve, contact a physician. |
| INGESTION: |
If conscious, have the person
swallow copious amounts of water and induce vomiting. Contact a physician. |
| SKIN: |
Wash contaminated area with water;
remove contaminated clothing, and shower. If irritation persists, seek medical attention. |
| EYE: |
Irrigate with copious amounts of
water. If irritation persists, seek medical assistance. Contact lenses should not be worn
if working with metal dusts and powders. |
