Notes	Results are provided for the presence and amount or concentration of a specific element or elements. The stated identity of the actual sample contents (such as a specific form or compound) is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes. The physical form of a sample (dust, mist, or fume) is identified by the compliance officer using available documentation of materials and processes. A pre-filter, consisting of a mixed cellulose ester filter in a polystyrene cassette, is used with the active sampler. The pre-filter assembly should be connected to the sampling tube with the minimum amount of Tygon tubing necessary. The filter of the sampler will be analyzed separately and reported as [(Aryl and Inorganic) (as Hg), analyte code M111] based on the collection of particulate Mercury. The Hydrar or Hopcalite sorbent material will be analyzed and reported as [Mercury (Vapor) (as Hg), analyte code 1631]. These two results could then be combined to evaluate the transitional limit of TWA total Mercury, 1 mg/10m³, (vapor and particulate). Passive air sampling not recommended.

Results are provided for the presence and amount or concentration of a specific element or elements. The stated identity of the actual sample contents (such as a specific form or compound) is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes.

There is no need to contact SLTC before sampling.

This analysis can be pre-analyzed gravimetrically if collected on a pre-weighted PVC filter obtained from SLTC.

*These 3 codes are used for bulk sample results in place of their metal oxides.

**Please note that this is NOT hexavalent chromium.

Notes	The METALSSG-1 sampling group members are analyzed using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) to target the expanded standards metals As, Cd, and Pb with high sensitivity (clean samples and smear tabs only). If lead is the only analyte of interest, use the single analyte code 1591. If the filter is not overloaded, samples may be collected up to an 8-hour period.	Results are provided for the presence and amount or concentration of a specific element or elements. The stated identity of the actual sample contents (such as specific form, valence state, or compound) is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes. Smaller filters recommended for sampling inside welding hoods.	If the filter is not overloaded, samples may be collected up to an 8-hour period. Results are provided for the presence and amount or concentration of a specific element or elements. The stated identity of the actual sample contents (such as a specific form or compound) is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes. The physical form of a sample (dust, mist, or fume) is identified by the compliance officer using available documentation of materials and processes.
Special requirements	For high sensitivity, request any or all of analytes listed in METALSSG-1 (0260, C141, & 1591).	For the entire suite of analytes listed in METALSSG-2, request analyte code 2587.	For the entire suite of analytes listed in METALSSG-3, which may be found during soldering and brazing operations, request analyte code S131.

Notes: OSHA considers "lead" to mean elemental lead, all inorganic lead compounds, and a class of organic lead compounds called lead soaps. This standard does not apply to other organic lead compounds. Note: Large nonferrous foundries (20+ employees) are required to achieve the PEL of 0.05 mg/m³ by means of engineering and work practice controls. Small nonferrous foundries (<20 employees) are required to achieve an 8-hour TWA of 0.075 mg/m³ by such controls. See 29 CFR 1910.1025.		Notes: NIOSH considers "lead" to mean metallic lead, lead oxides, and lead salts (including organic salts such as lead soaps but excluding lead arsenate. Air concentrations should be maintained so that worker blood lead remains less than 0.06 mg Pb/100 g of whole blood. See Appendix C, Supplementary Exposure Limits.
