SECTION 7. HANDLING AND STORAGE
USAGE PRECAUTIONS: Wash hands and face thoroughly after working with material. Protect from light
STORAGE PRECAUTIONS: Store at room temperature (15 to 25oC recommended). Keep well closed and protected from direct sunlight and moisture.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Protective gloves made of polyvinyl alcohol (PVA) are required. Use of a laboratory coat is suggested. Safety goggles or safety glasses with side shields are required if
there is any possibility of chipping or dust creation. Respirators must be worn when the threshold limit is exceeded. Provide adequate general mechanical ventilation, and
local exhaust ventilation. When handling quantities of this material, be sure to wear appropriate protective equipment as described. Eye wash should be readily available.
Wash thoroughly after handling. Do not take internally. Avoid breathing dust when generated. For persons with sensitive existing medical conditions, medical advice
should be sought before employing on tasks involving exposure to this material.

SECTION 12. ECOLOGICAL INFORMATION
The following applies to silver compounds in general: biological effects: silver ions toxic for aquatic organisms; bacteria: Ps. putida toxic from 0.006 mg/l up; protozoa:
U. parduczi toxic from 0.1 mg/l up; arthropods: D. daphnia LC50: 0.5 mg/l; algae: M. aeruginosa toxic from 0.0007 mg/l up; Sc. quadricauda toxic from 0.009 mg/l up
Due to the poor solubility of the product, no harmful effects on aquatic organisms are to be expected when the product is handled and used with due care and attention.
