About
caustics
Caustics are strong alkaline chemicals, corrosive to many materials
including human tissue. Sodium hydroxide (NaOH) and potassium hydroxide
(KOH) are the two most important caustics used in industry, with over
10 million tons of NaOH alone produced annually in its various forms.
Mishandled, caustics can cause serious harm to the environment, and
workers exposed to caustics can experience long-term health problems
or even death. It is critical that workers who handle sodium hydroxide
or potassium hydroxide, and that response personnel who must respond
to an emergency involving one of these chemicals, be well educated in
the hazard properties of caustics.
About the film
"Sodium Hydroxide & Potassium Hydroxide,"
sixth in the award-winning HazChem Series of emergency response
and right-to-know training videos, tells where these caustics are
found and in what common forms. The program provides basic information
on bases and acids, explaining the relevance of Ph and how it is measured.
It advocates an active program of accident prevention and safety inspection.
The film explains the forms that caustics
may take and teaches safe storage and handling procedures. Typical
containers used for storage and transportation are described, and
proper protective clothing and respiratory protection, safety precautions
such as showers and warning signs, and safe loading and unloading
techniques are also discussed.

The hazard properties
of sodium hydroxide and potassium hydroxide are very similar. The program
covers flammability and reactivity properties, and discusses symptoms
of exposure and medical treatment for victims. The film also outlines
priorities for the incident commander during incidents involving NaOH
or KOH, and tells what the factors are in his decision whether to mount
an offensive or defensive strategy in controlling the incident. Other
topics covered include selecting protective clothing and respiratory
protection for emergency responders, protecting water supplies from
spills, avoiding or containing runoff, using foams or spray fog nozzles
to control vapors, using dry chemicals or carbon dioxide to extinguish
fires, decontamination procedures, and overseeing the clean-up crew
to make sure that clean-up activities are carried out safely. (25 minutes)
About the HazChem Series
Each film in the HazChem Series focuses on a different product
or group of products. Programs combine footage of actual incidents
with action-packed, realistic training sequences. The films are designed
to provide training to persons who are expected to respond to an emergency
involving these hazardous materials.
HazChem films have been the winners of
numerous awards for both filmmaking excellence and technical content.
Among the honors received by HazChem programs are the prestigious
Cine Golden Eagle award, the Society for Technical Communication Award
of Excellence, the Telly Award, and the Silver Apple Award from the
National Education Film and Video Festival.
