NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 100 ppm

Potential Symptoms: Nausea, vomiting; respiratory, skin, and eye irritation; blurred vision; cough, sore throat; dizziness; wheezing, shortness of breath, feeling of chest tightness, pulmonary edema; dermatitis; INGES ACUTE: Abdominal pain; diarrhea.

Health Effects: Irritation-Eye, Nose, Throat, Skin---Marked (HE14); Respiratory sensitization (HE9).

Affected Organs: Eyes, skin, respiratory system

Notes:

  1. Large-scale occupational exposures have occurred when boiler steam containing this chemical as a corrosion inhibitor was released into the workplace.

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Silica Gel Tube (300/150 mg sections, 45/60 mesh, See Note)
    analytical solvent: 0.2N HCl in (4:1) Methanol:Water
    maximum volume: 24 Liters
    maximum flow rate: 0.2 L/min
    current analytical method: Gas chromatography; GC/FID
    method reference: OSHA Modified NIOSH Analytical Method (NIOSH 2007 [28 KB PDF, 5 pages])
    method classification: Partially Validated
    note: Immediately after sampling, transfer each section of the tube to separate vials containing 2 mL desorbing solvent, 0.2 N HCl in methanol:water (4:1). OSHA personnel may obtain vials containing solvent from the Salt Lake Technical Center.

On-Site Sampling Techniques/Methods:

  • device: Detector Tube
    manufacturer: Gastec
    model/type: 180L
    sampling information: 1 stroke
    upper measurement limit: 12 ppm
    detection limit: 0.12 ppm
    overall uncertainty: 16% for 0.6 to 2.4 ppm, 8% for 2.4 to 12 ppm
    method reference: on-site air secondary (manufacturer)
