Routes of entry: inhalation: yes skin: yes ingestion: no
reports of carcinogenicity: ntp: no iarc: no osha: no
health hazards acute and chronic: short term exposure to welding fumes,
gases or dust may result in discomfort such as dizziness, nausea,
fever, dryness and/or irritation of nose, throat and eyes. Skin
sensitivity may also be noted. L ong term exposure to
fumes/gases/dust may cause pulmonary irritation or pneumoconiosis;
& siderosis from iron fumes.
explanation of carcinogenicity: nickel and chromium are considered
possible carcinogens under osha. Respiratory cancer from welding is
unconfirmed.
effects of overexposure: exposure to welding fumes may result in
discomfort such as dizziness, nausea, fever, dryness and/or
irritation of nose, throat and eyes. Skin sensitivity may also be
noted. Watery eyes, headache, brea thing difficulty, frequent
coughing and/or chest pains may occur from acute exposure. Toxic
gases can be fatal.
medical cond aggravated by exposure: individuals with impaired pulmonary
function or illness may have symptoms exacerbated by irritants
contained in welding fumes.
First aid: in case of electrical shock, turn off power prior to removal
from exposure area and administration of first aid. Remove from
exposure area and call for medical aid. Administer oxygen if
breathing is d ifficult. If not breathing, begin artificial
respiration. If no detectable pulse, begin external heart massage.
employ first aid techniques recommended by the american red cross.

Reports of carcinogenicity: ntp: yes iarc: yes osha: yes
health hazards acute and chronic: acute: inhalation-inhaled particulate
may irritate the respiratory tract. Excessive inhalation of
sluminum, cobalt, copper, magnesium, nickel & zinc can cause
respiratory irritation, cough, bronchitis , chills, "metal fume
fever" & asthma-like symptoms. Ingestion-ingestion of large doses
may cause nausea, vomiting, & diarrhea. Skin-may cause irritation &
in some individuals an allergic dermatitis w hen elements such as
chrome, cobalt, copper & nickel are present. Eyes-contact with
particulate metal (dust, fume or powder) may inflame the
conjunctiva.
explanation of carcinogenicity: chromium, cobalt & nickel-osha requires
that chromium & its compounds, cobalt & its compounds, & nickel &
its compounds be considered as carcinogens because thay are so
classified by iarc &/or ntp. We lding fumes-osha requires that
welding fumes be considered as carcinogens because they are so
classified by iarc.
effects of overexposure: chronic health effects of
overexposure-respiratory disease with symptoms ranging from
shortness of breath & cough to permanent disability due to loss of
lung function; sensitization or hypersensitivit y & fibrosis of
subsequent effects on the heart may be caused by excessive exposure
to dust or fumes containing cobalt, nickel, titanium & tungsten.
central nervous system depression has been identifi ed with
excessive manganese exposure. Insoluble nickel compounds &
hexavalent chromium compounds have been linked to nasal, bronchial
& lung cancers. Aluminum & iron have been indicated to cause gastr
o-intestinal disorders in the lung.
medical cond aggravated by exposure: individuals who may have ahd an
allergic reaction or sensitivity to metals such as chromium,
copper, cobalt & nickel may encounter skin rash or dermatitis if
skin contact with this product occurs.
First aid: iinhalation-breathing difficulty caused by inhalation of dust
or fume, move individual to fresh air & administer oxygen as
needed. If breathing has stopped, perform artificial respiration.
obtain medi cal aid at once. Ingest-contact poison control center.
unless poison control adviceses otherwise, have conscious person
drink 1-2 glasses of water. Do not induce vomiting unless large
amounts are inge sted. Obtain aid. Skin-cuts & abrasions can be
treated by standard first aid. If irritaiton develops, obtain
medical aid. Eyes-flush dust or powder from eye with water for 15
mins. If irritation or re dness occurs, obtain medical aid.
