Product Overview

8. Exposure Controls and Personal Protection (PPE)

Respiratory Protection: If engineering controls (ventilation) are not sufficient to maintain exposure below occupational exposure limits, use a NIOSH-approved respirator with an organic vapor cartridge or a supplied-air respirator.
Eye Protection: Chemical safety goggles are mandatory. A face shield is recommended when handling open containers or during transfer operations.
Skin Protection: Wear chemical-resistant gloves (typically Nitrile, Butyl, or Neoprene depending on the exact solvent concentration). Wear long-sleeved shirts and long pants, or a full chemical suit for heavy exposure risk.
Hygiene: Emergency eyewash stations and safety showers must be accessible in the immediate work area.

Likely non-flammable or low flammability; consult MSDS for specific extinguishing media and hazards.
Use standard extinguishing media; firefighters should wear SCBA and full protective gear if involved with product fire.

Flush immediately with plenty of water. Remove and wash contaminated clothing before reuse. Inhalation:

Other Hazards:

May release toxic chlorine gas if mixed with acids or ammonia-based cleaners.
Reactive with reducing agents.

Causes serious eye irritation (Category 2A).
May cause skin irritation (Category 2).
Harmful if swallowed in large quantities.
Not classified as flammable or reactive.
