Section 8 - Exposure Controls/Personal Protection
Note: Steel Products under normal conditions do not present an inhalation, ingestion, or contact health hazard. These products contain trace
quantities of various elements but not at reportable levels under the OSHA Hazard Communication Standard Limit (29 CFR 1910.1200).

(a) OSHA Annotated Table Z-1 https://www.osha.gov/dsg/annotated-pels/tablez-1.html
(b) Denotes short term exposure limit (STEL).
(c) Denotes “ceiling limit” which is not to be exceeded at any time.
* Subject to Section EPCRA 313 reporting.
8(b) Appropriate Engineering Controls: Local exhaust ventilation should be provided when sawing, grinding or machining
to prevent excessive dust or fume exposure. During welding, burning or brazing please follow the ANSI Standard Z49.1
“Safety in Welding and Cutting”.
8(c) Individual Protection Measures:
RESPIRATORY: For welding or burning – NIOSH/MSHA approved dust and fume respirators should be used to avoid
excessive inhalation of particulates. Appropriate respirator selection depends on the magnitude of exposure
SKIN: Protective gloves should be worn as required for welding, burning, or handling operations. Cut resistant gloves
should be used when handling steel products.
EYE: Use safety glasses or goggles as required for welding, burning or handling operations.
OTHER PROTECTIVE EQUIPMENT: Depending upon the conditions of use and specific work situations, additional protective
equipment and/or clothing may be required to control exposures.
