SECTION VII HANDLING AND STORAGE
The use of appropriate respiratory protection is advised when concentrations exceed
any established exposure limits (see Sections 8). Avoid contact with eyes, skin, and
clothing. Wash thoroughly after handling. Wash contaminated clothing or shoes. Use
HANDLING: good personal hygiene practices. Avoid systems that would tend to segregate dust
or any components of this product. Avoid accumulation of fugitive dust as high
concentrations of sulfur dust may present an explosion hazard. Follow standard
Hot Work guidelines when working around this product.
Use and store this material in cool, dry, well-ventilated areas. Store only in approved
containers. Keep container(s) tightly closed. Keep away from any incompatible material
STORAGE:
(see Section 10). Protect container(s) against physical damage. Material may absorb
moisture from the air.
