OSHA IMIS Code Number: 0577
IMIS Name History: Portland Cement (less than 1% Crystalline Silica) prior to 9/1/89
Chemical Abstracts Service (CAS) Registry Number: 65997-15-1
NIOSH Registry of Toxic Effects (RTECS) Identification Number: VV8770000

OSHA Permissible Exposure Limit (PEL):
General Industry: 29 CFR 1910.1000 Z-1 Table -- 15 mg/m3 TWA; 29 CFR 1910.1000 Z-3 Table -- 50 mppcf TWA (PEL listed under Silicates (less than 1% crystalline silica), Portland Cement)
Construction Industry: 29 CFR 1926.55 Appendix A -- 50 mppcf TWA (PEL listed in Mineral Dusts Table under Silicates (less than 1% crystalline silica), Portland Cement)
Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 15 mg/m3 TWA; Skin 10; 50 mppcf TWA (PEL listed in Mineral Dusts Table under Silicates (less than 1% crystalline silica), Portland Cement)
American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 10 mg/m3 TWA; The value is for particulate matter containing no asbestos and <1% crystalline silica.
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 10 mg/m3 TWA
NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 5000 mg/m3
Potential Symptoms: Irritation of eyes, skin, nose; cough, sore throat, expectoration; exertional dyspnea (breathing difficulty); wheezing, asthma, chronic bronchitis; dermatitis, skin burns. INGES. ACUTE: Burning sensation, abdominal pain.
Health Effects: Irritation-Eyes, Nose, Throat, Skin---Marked (HE14); Cumulative lung damage (HE10)
Affected Organs: Eyes, skin, respiratory system
Notes: 1) Skin sensitization may occur if the mixture contains hexavalent chromium. 2) A case of pulmonary alveolar proteinosis was described in a cement truck driver exposed to Portland cement dust and having silicon-containing particles in his lung biopsy material. 3) Increased risks for some types of cancer (lung, bladder) among male cement production workers was reported, but adjustment for smoking in the calculations may have been inadequate. 4) In one pulmonary function study of cement production workers, airflow limitation was more likely to occur where dust exposure was highest (packing, crusher, crane operations), in older workers, in those employed longer and with higher cumulative dust exposure.
5. Airborne dust samples taken at various areas of a cement production plant in Saudi Arabia ranged from 2.13 mg/m3 in the kilns to 59.52 mg/m3 in the quarry area.

Laboratory Sampling/Analytical Method:
- sampling media: tared 37-mm diameter low-ash polyvinyl chloride filter
maximum volume: 240 Liters
maximum flow rate:1.0 L/min
current analytical method: Gravimetric
method reference: OSHA Analytical Method (OSHA PV2121)
method classification: Partially Validated
note: OSHA personnel can obtain tared sampling media from SLTC.
note: If the net weight of the sample yields a concentration below the standard for the substance, SLTC will perform no further work on that sample. If the net weight corresponds to an amount greater than the standard, the sample may be analyzed for the appropriate element and the result reported as the substance. SLTC does not presently have the equipment necessary to perform this analysis.
current elemental analysis method: X-ray Diffraction
method reference: OSHA Analytical Method (OSHA ID-207)
method classification: Fully Validated
