3.5.2 T22 (CAM 17) Metals <br /> Types/Source: Heavy metal containing soils along railroad tracks; CAM 17 metals include <br /> elemental, organic and inorganic compound forms of chromium, copper, <br /> lead, nickel,and zinc. <br /> Exposure Route: Inhalation; ref. Attachment B-T22 (CAM 17) Metals <br /> Target Organ(s): Refer Attachment B <br /> Qualified Exposure Risk: Low <br /> Hazard Controls: <br /> • Isolation—restrict access during sampling tasks; avoid contact with potentially contaminated soils <br /> • Engineering Controls—Safe work practices and wet sampling procedures, <br /> Dampen dry soils prior to sampling to suppress dust hazards; <br /> Negative Exposure Assessment: Results of industrial hygiene monitoring of representative tasks and <br /> sampling procedures for aerially deposited inorganic lead (ADL) using these controls document <br /> exposures consistently below the PEL and TLV for airborne lead (ref. T8 CCR§1532.1(d)(5)(A)). <br /> • PPE—eye (safety glasses or goggles), hand protection(leather and/or impermeable gloves); and, <br /> • Good sanitation and personal hygiene; see Section 4.2. <br /> 3.5.2.1 Arsenic <br /> T8 CCR GISO Article 110 Regulated Carcinogen §5214 <br /> Exposure Route: Inhalation, ingestion, skin contact; ref.
