Potential Health Effects:
- Eye Contact Causes mild to severe irritation. May cause burns if not flushed with water.
- Skin contact Prolonged exposure may cause moderate irritation. May cause burns if not flushed
with water.
- Inhalation Inhalation of dust may irritate or burn nose, throat and lungs.
- Ingestion Small amounts (tablespoonful) swallowed are not likely to cause injury; however
swallowing large amounts may irritate or burn digestive tract.
Chronic effects/Carcinogenicity Not known to cause cancer.
NFPA Ratings (Scale 0-4) Health = 1, Fire = 0, Reactivity = 1.
HMIS Ratings (Scale 0-4) Health = 1, Fire = 0, Reactivity = 1.

4. First-aid measures
Eye contact Holding the eyelids apart, flush eyes promptly with copious flowing water for at least
20 minutes. Get medical attention immediately.
Skin contact Remove contaminated clothing. Wash skin thoroughly with mild soap and plenty of
water for at least 15 minutes. Wash clothing before re-use.
Get medical attention if irritation occurs.
Inhalation In case of dust inhalation or breathing fumes released from heated material, remove
person to fresh air.
Keep him quiet and warm. Apply artificial respiration if necessary and get medical
attention immediately.

Note to physician Treat symptomatically and supportively.
5. Fire - fighting measures
Flash point Not applicable
Flammable/Explosion limits Not explosive/Not flammable
Suitable extinguishing media Material is not combustible. Use extinguishing media appropriate to surrounding fire
conditions. Because material will readily dissolve in water to form a weak acid
solution, avoid water contact with material if possible.
Fire fighting procedure Product readily dissolves in water to form a weak acid solution. If using water, wear
acid protective equipment. No gases or toxic fumes are emmitted from this reaction.
However, if elevated temperatures (> 806癋) are reached, self-contained breathing
apparatus should be worn.
Unusual fire and explosion Will decompose above 806癋 (430癈) releasing poisonous and corrosive fumes of
hazards sulfur oxides.
6. Accidental release measures
Methods for cleaning up Vacuum or shovel material and place in disposal container. Avoid excessive dust
generation. Dilute residual material with ample supply of water and direct to sanitary
sewer if Federal, State or Local regulations permit.
- Water Readily dissolves in water to form a weak acid solution. If water is isolated or can be
contained, neutralize with weak alkaline solution.

11. Toxicological information
Toxicity No human data are available for this product.
Acute toxicity:
- Rat oral LD50 2800 mg/kg
- Dermal irritation (rabbit) This material is neither corrosive nor destructive.
Carcinogenicity Not classified by IARC, OSHA, EPA.
Not included in NTP 11th Report on Carcinogens.
12. Ecological information
Information on ecological This product redily dissolves in water to form a weak acid solution. A 0.05 percent or
effects greater (by weight) solution of this product is likely to be acutely harmful to fish and
other aquatic organisms.
Environmental fate Material will decompose in soil. Studies show that there are no adverse effects of
applying the main ingredient in this product (sodium bisulfate), directly to crops.
