SODIUM HYDROXIDE - NaOH
Sodium Hydroxide is caustic and is one of several alkaline compounds referred to as “lye”
Inhalation of Sodium hydroxide dust, mist or aerosol may cause irritation of the mucous membranes
Sodium hydroxide is odorless There is no antidote for sodium hydroxide Treatment consists of respiratory and cardiovascular
support Chemical Used In The Neutralization Of VX
SODIUM HYDROXIDE
HEALTHMaterial may cause severe injury or
death if toxic fumes are inhaled, if ingested or comes in contact with skin
Avoid any skin contactEffects of contact or inhalation may be
delayed
SODIUM HYDROXIDE (cont’d)
FIRE OR EXPLOSIONNon-combustible substance itself does
not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with metals may evolve flammable hydrogen gas
Containers may explode when heated
SCENARIO
It was a typical August day, sun shining, hot and humid, with a light breeze blowing from the south west. A transport tanker, hauling ethanol, was headed north on U.S. 41, and in the process of making a left turn onto U.S. 136. The driver of the tanker apparently did not see the southbound truck approaching the intersection. This truck was carrying a load of sodium hydroxide. The southbound driver, realizing there was to be an impact, veered his vehicle to the right, skidding sideways into and capsizing the tank truck.
Southbound Northbound
SCENARIO (cont’d)
A valve on the tanker popped open, permitting some ethanol to escape on the ground. After the impact, the southbound truck lost some containers of sodium hydroxide. Sparks from the tanker ignited the fuel. The fire and heat from the fire created a plume while heating the sodium hydroxide.
