NOTE: All commercial metals contain small amounts of various elements in addition to those specified. These small quantities, frequently referred to as 鈥渢race鈥? or
鈥渞esidual鈥? elements, generally originate in the raw materials used. Typical levels of commonly involved trace or residual elements that may be encountered in steel
products are provided in Annex I so that their potential hazards may be considered.
NOTE: All exposure limits are based on 8-hour time-weighted average values.

SECTION V 鈥? HEALTH HAZARD DATA
HEALTH HAZARDS (ACUTE AND CHRONIC 鈥? INCLUDE TARGET ORGAN EFFECTS)
Respiratory exposure to crystalline silica can cause lesions in the respiratory bronchioles in early stages to later development of massive fibrosis.
This is usually developed over an extended period of time in a gradual progression; however, progression of symptoms usually continues after dust
exposure ceases.
Long-term inhalation of Iron Oxide dust may produce a benign pneumoconiosis (siderosis).
SIGNS AND SYMPTOMS OF OVEREXPOSURE
Cough, dyspnea, wheezing, and repeated non-specific chest illness.
PRIMARY ROUTES OF ENTRY Inhalation Eye Contact Other(specify)
YES YES
EMERGENCY AND FIRST AID PROCEDURES
Inhalation: Remove to fresh air. Administer oxygen. Seek medical attention.
Eye Contact: Flush eyes thoroughly with running water, including under the eyelids for at least 15 minutes. Seek medical attention.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
IARC has listed crystalline silica as a Group 1 known Human Carcinogen

HAZARDOUS DECOMPOSITION PRODUCTS:
Steel products under normal conditions do not present an inhalation, ingestion, contact health or environmental hazard. However, operations such as
burning, welding, sawing, brazing, grinding, and possibly machining, etc., 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 health hazards.
MAY OCCUR CONDITIONS TO AVOID
HAZARDOUS NONE
POLYMERIZATION WILL NOT OCCUR

SECTION VII 鈥? SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Clean-up personnel should be protected against eye contact and inhalation of dust. Provide mechanical ventilation, and avoid raising dust clouds.
Place in closed container for disposal.
WASTE DISPOSAL METHOD

SECTION VIII 鈥? SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION (specify type)
NIOSH approved particulate respirators. Appropriate respirator selection depends upon type and magnitude of exposure.
VENTILATION SPECIAL
Mechanical general and/or local exhaust ventilation. NONE
SPECIAL PROTECTION INFORMATION EYE PROTECTION (specify type)
Protective clothing and work gloves Safety glasses with side shields.
OTHER PROTECTIVE EQUIPMENT WORK/HYGIENIC PRACTICES
None Particulates to minimize dust generation.
SECTION IX 鈥? SPECIAL PRECAUTIONS
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING
Good housekeeping techniques such as vacuuming should be used to remove dust accumulations and to prevent the generation of airborne dust.
Avoid the use of compressed air for removing settled dust; avoid inhalation of dust and contact with eyes.
OTHER PRECAUTIONS
NONE
