OSHA IMIS Code Number: 1987
Chemical Abstracts Service (CAS) Registry Number: 115-77-5
NIOSH, Registry of Toxic Effects (RTECS) Identification Number: RZ2490000

Exposure Limits
OSHA Permissible Exposure Limit (PEL) for General Industry: 29 CFR 1910.1000 Z-1 Table -- 15 mg/m3 TWA
OSHA Permissible Exposure Limit (PEL) for 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.

Monitoring Methods used by OSHA
Laboratory Sampling/Analytical Method:
-
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 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 material and the result reported as the substance.
current elemental analysis method: Gas Chromatography; GC/FID
method reference: OSHA SLTC In-House File
method classification: Not Validated
