Handling, storage and disposal
Summaries only, follow the supplier SDS for your grade
Safe handling
Fire: NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
General: PREVENT GENERATION OF MISTS!
Inhalation: Use ventilation, local exhaust or breathing protection.
Skin: Protective gloves.
Eyes: Wear safety goggles in combination with breathing protection.
Ingestion: Do not eat, drink, or smoke during work.
Storage
Fireproof. Separated from strong oxidants. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
Disposal
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal.
Exposure limits and toxicity
Occupational exposure limits and toxicity data
- OSHA PEL, 8-hour TWA
- 500 ppm (2000 mg/m³)
- NIOSH REL, TWA
- 85 ppm (350 mg/m³)
- NIOSH REL, ceiling
- 440 ppm (1800 mg/m³) [15 minutes]
- ACGIH TLV, 8-hour TWA
- 400 ppm
- ACGIH TLV, STEL
- 500 ppm
- IDLH
- 750 ppm
Short-term exposure: The substance is irritating to the skin. The vapour is irritating to the respiratory tract. If swallowed the substance easily enters the airways and could result in aspiration pneumonitis. The substance may cause effects on the central nervous system. Long-term exposure: The substance defats the skin, which may cause dryness or cracking.
