Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
Personal protective equipment
Eye/face protection
Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Body Protection
Complete suit protecting against chemicals, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use (EN 143) respirator cartridges as a backup to engineering controls. If th full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Control of environmental exposure
Do not let product enter drains.
Stability and reactivity
Stable under recommended storage conditions.
Possibility of hazardous reactions
Ammonium hypophosphite liberates spontaneously flammable phosphine at about 240°C; Some inorganic materials, such as hypophosphites, tend to form explosive mixtures with perchloric acid when hot
Conditions to avoid
Avoid moisture.
Incompatible materials
Strong oxidizing agents, Strong bases, Acid chlorides, Acid anhydrides, Corrodes metal
Hazardous decomposition products
Ammonium hypophosphite liberates spontaneously flammable phosphine at about 240°C.
Disposal considerations
Offer surplus and non-recyclable solutions to a licensed disposal company. Dissolve or mix the material with a combustible solvent and burn in a chem scrubber.
