• Do not use unapproved materials (brass, copper, carbon steel, rubber,
etc.) for transfer or storage systems.
Caps on the reagent bottles are made with a special porous liner that
allows venting of gas. The venting cap always must be used on the bottle
of hydrogen peroxide. As a precaution, the reagent bottles are shipped in a
plastic bag. If there is evidence of leakage during shipment, wear gloves
when removing the bottle from the bag and rinse the bottle with water
when removed from the bag. Rinse the bag before disposal.
3.3 Using Sulfuric Acid
Read and observe all warnings on the reagent labels and Material Safety
Data Sheets that accompany the sulfuric acid.
Concentrated sulfuric acid used in the digestion process should be
handled correctly and with caution. Sulfuric acid is a strong acid and
strong oxidizer; it can cause burns if splashed on the skin and permanent
damage if eye contact occurs. This caustic action is much more severe if
the acid is hot. In case of eye or skin contact, flush eyes and/or skin
with water for 15 minutes. Immediately call a physician.
Sulfuric acid mist or vapor has been classified by the International
Agency for Research on Cancer (IARC) as a possible human carcinogen.
Sulfuric acid is a strong oxidizer. It may ignite or explode on contact with
many different chemicals. Follow proper storage regulations.
3.4 Clean Up of Spills and Leaks
Use extreme caution when cleaning spills and leaks throughout the entire
digestion procedure. Your facility may require that only trained
individuals wearing appropriate protective equipment (gloves, goggles,
face shields and chemical resistant clothing) respond to a spill or leak to
ensure the Digesdahl is properly cleaned.
A spill, overflow, or eruption from the Digesdahl apparatus may leave a
residue on the equipment or other surfaces. Cleaning the residue must be
done cautiously. Do not use alternative cleaning methods or cleaning
agents not authorized or endorsed by Hach Company; they may damage
the equipment.
While cleaning a spill or leak, please follow the safety measures below:
1. DO NOT attempt to clean the apparatus if it is hot; this could cause the
glass to shatter. Let the apparatus cool before cleaning it.
