Ingestion? Yes
Health Hazards (Acute and cnromc) Acid esters: Risk of irritation to eyes. Irritating to respiratory system. May degrease
skin.
Carcinogenicity None NIP? No
IARC Monographs? No OSHA Regulated? No
igns and symptoms of exposure Red irritated skin. May cause light-headedness when used in poorly ventilated area without
proper vapor mask..
Medical Conditions
Generally Aggravated by Exposure Persons susceptible or sensitive to eye and respiratory irritation
Emergency and First Aid Procedures Inhalation: Move to fresh air; Skin: Wash skin immediately with water. Eyes: Flush with
water for at least 15 minutes, consult physician; Ingestion: Drink water and consult physician.
Section VII—Precautions for Safe Handling and Use
Use safety glasses and latex or nitrile gloves. Work in well ventilated area.
Waste Disposal Method ABC can be disposed as waste water or landfilled when in compliance with local regulations
Precautions to Be Taken in Handling and storing May be F lammable - Do not store near ignition sources or at elevated
temperatures.
Avoid long storage times, will break down to innocuous products
Other Precautions Wear PPE when handling and keep containers tightly closed when stored.
Section VII—Control Measures
Respiratory P otection (speedy type) If ventilation inadequate or in confined space, use respirator with filter (DIN 141)
Ventilation Local Exhaust Acid esters have low vapor pressure (2.7 Special Ensure fumes can not reach ignition source

SECTION 6 - HEALTH HAZARD DATA
HEALTH EFFECTS
The effects of exposure to this material have not been determined. Safe handling of
this material on a long-term basis will avoid any possible effect from repetitive acute
exposures. Below are possible health effects based on information from similar
materials. Individuals hyper allergic to enzymes or other related proteins should not
handle.
Ingestion: Ingestion of large quantities may result in abdominal discomfort including
nausea, vomiting, cramps, diarrhea, and fever.
Inhalation: Hypersensitive individuals may experience breathing difficulties after
inhalation of aerosols.
Skin Absorption: N/A

Skin Contact: May cause skin irritation. Hypersensitive individuals may experience
allergic reactions to enzymes.
Eye Contact: May cause eye irritation.
FIRST AID
Ingestion: Get medical attention if allergic symptoms develop (observe for 48 hours).
Never give anything by mouth to an unconscious or convulsing person.
Inhalation: Get medical attention if allergic symptoms develop.
Skin Absorption: N/A
Skin Contact: Wash affected area with soap and water. Get medical attention if
allergic symptoms develop.
Eye Contact: Flush eyes with plenty of water for at least 15 minutes using an eyewash
fountain, if available. Get medical attention if irritation occurs.
NOTE TO PHYSICIANS: All treatments should be based on observed signs and
symptoms of distress in the patient. Consideration should be given to the possibility
that overexposure to materials other than this material may have occurred.
SECTION 7 - SPILL AND LEAK PROCEDURES
Reportable quantities (in Ibs of EPA Hazardous Substances): N/A
Steps to be taken in case of spill or release: No emergency results from spillage.
However, spills should be cleaned up promptly. All personnel involved in the cleanup
must wear protective clothing and avoid skin contact. Absorb spilled material or
vacuum into a container. After clean-up, disinfect all cleaning materials and storage
containers that come in contact with the spilled liquid.
Waste Disposal Method: No special disposal methods are required. The material may
be sewered, and is compatible with all known biological treatment methods. To reduce
odors and permanently inactivate microorganisms, mix 100 parts (by volume) of DHC
consortium with 1 part (by volume) of bleach. Dispose of in accordance with local, state
and federal regulations.
