OSHA Material Safety Data (MSD Sheet)

NAME: Ozone

IMIS: 1980

CAS: 10028-15-6

NIOSH: RTECS RS8225000

DESCRIPTION: Colorless gas with a very pungent, characteristic odor, associated with electrical sparks.

MW: 48

BP: -170 F

MP: -313 F

INCOM: All oxidizable materials, both organic and inorganic

Exposure Limits
OSHA GENERAL INDUSTRY PEL: 0.1 ppm, 0.2 mg/m3

OSHA CONSTRUCTION INDUSTRY PEL: 0.1 ppm, 0.2 mg/m3 TWA

ACGIH TLV: Heavy Work - 0.05 ppm TWA; Moderate Work - 0.08 ppm TWA; Light Work - 0.10 ppm TWA; Heavy, Moderate, or light workloads (< or 2 hrs - 0.20 TWA; Appendix A4 (Not Classifiable as a Human Carcinogen)

NIOSH REL: 0.1 ppm Ceiling

Health Factors
SYMPTOM(s): Eye, mucous membrane irritation; pulmonary edema, chronic respiratory disease

HEALTH EFFECTS: Irritation-Respiratory tract---Marked (HE14); Lung edema (HE11)

ORGAN: Eyes, respiratory system

Monitoring
PRIMARY SAMPLING/ANALYTICAL METHOD (SLC1):

MEDIA: Two Impregnated Glass Fiber Filters (37mm polystyrene cassette) coated with a solution containing NaNO2, K2CO3 and Glycerol in water

MAX V: 90 L MAX F: 0.5 L/min

MAX V: 90 L MAX F: 0.25 to 0.5 L/min ANL1: Ion Chromatography; IC .

REF: 2 (OSHA ID-214)

SAE: 0.07

CLASS: Fully Validated

NOTE: If high concentrations of Ozone (>0.2 ppm) are expected, use the lower flow rate. Impregnated filters must be used within 30 days of preparation. Sulfur dioxide, if present, will interfere. Please request oxidizer tubes if SO2 is known to be present. If unknown, please screen with sulfur dioxide detector tubes or automatically use the oxidizer tubes in series with the filter cassettes.
