| Note: The above listing is a summary of elements used in alloying stainless steels. Various grades of steel will contain different combinations of these elements. Trace elements may also be present in minute amounts. No permissible exposure limits (PEL) or thresholds limit values (TLV) exist for stainless steel. Values are applicable to component elements. |

| RESPIRATORY PROTECTION: Appropriate dust/mist/fume respiratorshould be used to avoid excessive inhalation of particulates. If exposure limits are reached or exceeded, use NIOSH approvedequipment. |
HANDS, ARMS, AND BODY: Protective gloves should be worn as required for welding, burning, or handling operations. |
| EYES AND FACE: Safety glasses should be worn when grinding orcutting. Face shields should be worn when welding or cutting. |
OTHER CLOTHING AND EQUIPMENT: As required depending on operations and safety codes. |
|
|
| |
| INHALATION: |
Remove to fresh air; if condition continues, consult a physician. |
| EYE CONTACT: |
Flush thoroughly with running water to remove particulate; obtain medical attention. |
| SKIN CONTACT: |
Remove particles by washing thoroughly with soap and water. Seek medical attention if condition persists. |
| INGESTION: |
If significant amounts of metal are ingested, consult physician. |

Stainless steel products in their solid state present no inhalation, ingestion, or contact health hazard. Operations such as burning, welding, sawing, brazing, grinding, and machining, which result in elevating the temperature of the product to, or above its melting point, or result in the generation of airborne particulates may present hazards. The major exposure hazard is inhalation. Effects or overexposure to fume and dust are as follows |
| ACUTE: Excessive inhalation of metallic fumes and dust may result in irritation of eyes, nose and throat. High concentrations of fumes and dust of iron-oxide, manganese, copper, zinc and lead may result in metal fume fever. Typical symptoms last from 12 to 48 hours and consist of a metallic taste in the mouth, dryness and irritation of the throat, chills and fever. |
CHRONIC: Chronic and prolonged inhalation of high concentrations of fumes or dust of the following elements may lead to the conditions listed opposite the element:
| |
Aluminum: Irritation of the eyes, nose and throat. |
| |
Chromium: Lesions of the skin and mucous membranes, possibly cancer of the nose or lungs- bronchogenic carcinoma |
| |
Cobalt: Respiratory tract irritation, skin rash |
| |
Copper: Irritation of the eyes, nose and throat, metal fume fever |
| |
Iron: Pulmonary effects, siderosis Pulmonary effects, siderosis |
| |
Manganese: Bronchitis, pneumonitis, lack of coordination |
| |
Molybdenum: Respiratory tract irritation, possible liver and kidney damage, bone deformity |
| |
Nickel: Lesions of the skin and mucous membranes, possibly cancer of the nose or lungs-bronchogenic carcinoma |
| |
Phosphorous: Necrosis of the mandible |
| |
Selenium: Nasal and bronchial irritation |
| |
Sulfur: (As sulfur dioxide) Edema of the lungs |
| |
Titanium: No chronic debilitating symptoms indicated |
| |
Columbium/Tantalum: No chronic debilitating symptoms indicated |
|
| MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Individuals with chronic respiratory disorders (i.e.: asthma, chronic bronchitis emphysema, etc.) may be adversely affected by any fume or airborne particulate matter exposure. |
| OCCUPATIONAL EXPOSURE LIMITS: See Products Ingredients Section I. Chromium and Nickel havebeen identified by the International Agency for Research on Cancer (IARC) and/or the National Toxicology Program(NTP) as potential cancer causing agents. |

EXTINGUISHING MEDIA: Does not present fire or explosion hazards under normal conditions. Use dry powder or sand on molten metal |
| FIRE AND EXPLOSION HAZARDSStainless tubular products do not present fire or explosion hazards under normal conditions. Fine metal particles such as produced in grinding or sawing can burn. High concentrations of metallic fines in the air may present an explosion hazard. |
EXTINGUISHING MEDIA NOT TO BE USED Do not use water on molten metal or fires caused by fine metal particles |

STABILITY |
INCOMPATIBILITY (MATERIALS TO AVOID) |
| Stable Unstable |
Reacts with strong acids to form hydrogen gas. |
| CONDITIONS TO AVOID: Stainless steel at temperatures above the melting point may liberate fumes containingoxides of iron and alloying elements. |
| HAZARDOUS DECOMPOSITION PRODUCTS: Metallic dust or fumes may be produced during welding, burning, grinding and possibly machining. Refer to ANSI Z49.1. |
|
|
| |
| SPILL OR LEAK PROCEDURES:Fine turnings and small chips should be swept or vacuumed. Scrap metal can be reclaimed for re-use. |
WASTE DISPOSAL METHOD*:Used or unused product should be disposed of in accordance with Federal, State, or Local Laws and Regulations.
*Disposer must comply with Federal, State, and Local disposal or discharge laws. |
|
|
| |
| In welding, precautions should be taken for airborne contaminants which may originate from components of the welding rod. |
| Arc or spark generated when welding or burning could be a source of ignition for combustion and flammable materials. |
