N O T E S
|
Household bleaches usually contain about 5% sodium hypochlorite (about pH11, irritant), and more concentrated bleaches contain 10-15% sodium hypochlorite (about pH13, corrosive).
Rinse contaminated clothes (fire hazard) with plenty of water.
Clorox and Javel water are trade names.
Also consult
ICSC #1119 (Sodium hypochlorite, active chlorine >10%).
