Information and Markings
Environmental Express HotBlocks
TM
provide an efficient method of digesting and storing water, wastewater, soil and sludge
samples for metals analysis. These innovative digestion systems allow samples to be digested in a corrosion-free environment.
In addition, samples are handled in a small area with minimal radiant heat loss. Users should be aware of potential dangers
from heating certain types of compounds. Such hazards may include explosion or the release of toxic or flammable gases.
Each HotBlock displays certain markings and symbols. All personnel working with the HotBlocks should have an
understanding of the following symbols and definitions:
• V = voltage
• ~ = alternating current
• Hz = frequency
• A = amperes
Unpacking Your HotBlock
