Hazards and Protection.
Keep tightly closed in a cool place in a tightly closed container.
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Wear resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
If workplace exposure limit(s) of product or any component is exceeded (see exposure guidelines), a NIOSH/MSHA approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators (negative pressure type) under specified conditions.
Small spill - Sweep up material for disposal or recovery. Large Spill - Shovel material into containers. Thoroughly sweep area of spill to clean up any residual material.
Metals, strong oxidizing agents.
When heated to decomposition, emits toxic fumes of hydrogen chloride.
Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment. Extinguish using media most appropriate for surrounding fire.
Lethargy, hyporeflexia, weakness, and subjective feeling of thirst and heat may occur. Excessive absorption of magnesium from cathartics may result in CNS depression and seizures, most notably in renal failure patients.
Swallowing small amounts of this material during normal handling is not likely to cause harmful effects. Swallowing large amounts may be harmful.
This material is a dust or may produce dust. Breathing small amounts of this material during normal handling is not likely to cause harmful effects. Breathing large amounts may be harmful.
Can cause skin irritation. Symptoms may include redness and burning of skin, and other skin damage.
Can cause eye irritation. Symptoms include stinging, tearing, redness, and swelling of eyes.
