Safety Data Sheet For W5 - Thick Bleach

W5 Thick Bleach is stable under normal storage but decomposes when heated, exposed to light, or contaminated with metals (e.g., iron, copper). It reacts violently with acids (releasing chlorine gas), ammonia (forming chloramine vapors), and reducing agents. The SDS warns against contact with organic materials (e.g., fabric, paper) as they may cause oxidation and heat generation. Hazardous decomposition products include chlorine and oxygen.

This is arguably the most important part of the safety data sheet for W5 Thick Bleach for the average user. The SDS mandates specific, immediate actions:

Safe handling instructions include using in well-ventilated areas, never mixing with other cleaning products (especially acids, ammonia, or organic solvents), and wearing chemical-resistant gloves (e.g., nitrile) and safety goggles. Storage requires a cool, dry, well-ventilated place away from direct sunlight, heat, incompatible materials (acids, reducing agents, organic matter), and out of reach of children. Containers must be kept tightly closed and upright to prevent leaks.

You won’t usually find a paper copy on the bottle. Instead:

Sodium hypochlorite is not flammable but is a strong oxidizer. In a fire, it can decompose to release toxic chlorine fumes. The SDS recommends using water spray, carbon dioxide, or dry chemical extinguishers, and firefighters should wear self-contained breathing apparatus (SCBA). For spills, the SDS advises evacuating the area, avoiding dust/ aerosol formation, and neutralizing with reducing agents (e.g., sodium thiosulfate) or absorbing with inert material (sand, vermiculite). Dilute spills with large amounts of water, but prevent entry into drains due to aquatic toxicity. Hazardous decomposition products include chlorine and oxygen
