OSHA IMIS Code Number: 1987

Chemical Abstracts Service (CAS) Registry Number: 115-77-5

NIOSH Registry of Toxic Effects of Chemical Substances (RTECS) Identification Number: RZ2490000

Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 29 CFR 1910.1000 Z-1 Table -- 15 mg/m3 TWA

Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 15 mg/m3 TWA

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 10 mg/m3 TWA

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 10 mg/m3 TWA

Health Factors

Potential Symptoms: Irritation of eyes, respiratory system. INGES. ACUTE: In animals: stool softening, diarrhea; tremors, ataxia, loss of righting reflex.

Health Effects: Nuisance particulate (HE19); LD50 (oral, guinea pig) 11.3 g/kg

Affected Organs: Eyes, respiratory system

Notes:

  1. Studies in rabbits indicated no skin irritation, but conjunctival instillation of a 50% aqueous suspension caused slight and transient eye irritation.
  2. Pentaerythritol is excreted unchanged in the urine.

Literature Basis:

  • NIOSH Pocket Guide to Chemical Hazards: Pentaerythritol.
  • NIOSH: Toxicologic review of selected chemicals: Pentaerythritol.
  • Pohanish, R.P. (editor): Pentaerythritol. Sittig's Handbook of Toxic and Hazardous Chemicals and Carcinogens, Fourth Ed., Vol. 2. Norwich, NY: Noyes Publications, William Andrew Publishing, 2002, pp. 1804-1805.

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: tared 37-mm diameter low-ash polyvinyl chloride filter
    maximum volume: 102 Liters
    maximum flow rate: 1.7 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 the Salt Lake Technical Center.
    note: If the net weight of the sample yields a concentration below the standard for the substance, the Salt Lake Technical Center 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 material and the result reported as the substance.
    current elemental analysis method: Gas Chromatography; GC/FID
    method reference: OSHA (In-House File)
    method classification: Not Validated
